m(x) = (x-3)(x+5)

Answers

Answer 1

The equation m(x) = (x-3)(x+5) is written in intercept form.

How to determine if the equation is written in Standard, Intercept, or Vertex Form

The equation m(x) = (x-3)(x+5) represents a quadratic function.

Analysing the equation.

Standard form of a quadratic equation is written as:

f(x) = ax^2 + bx + c, where a, b, and c are constants.

Intercept form of a quadratic equation is written as:

f(x) = a(x-p)(x-q), where a, p, and q are constants representing the x-intercepts.

Vertex form of a quadratic equation is written as:

f(x) = a(x-h)^2 + k, where a, h, and k are constants representing the vertex coordinates.

The factors (x-3) and (x+5) represent the x-intercepts of the quadratic function.

Therefore, the equation m(x) = (x-3)(x+5) is written in intercept form.

1520−{64÷−4}−[37( √ 121+345)(43−|−583|)+405]−{1745÷5−64 }

Answers


Answer:

36,425,886

Step-by-step explanation:

To rewrite the expression mathematically and simplify it, let's break it down step by step:

1520 − {64 ÷ -4} − [37(√121 + 345)(43 − |-583|) + 405] − {1745 ÷ 5 - 64}

Step 1: Evaluate the expressions within the absolute value symbols:
|-583| = 583

Step 2: Evaluate the square root:
√121 = 11

Step 3: Simplify the expression within the brackets:
37(11 + 345)(43 - 583) = 37(356)(-540)

Step 4: Evaluate the divisions:
64 ÷ -4 = -16
1745 ÷ 5 = 349

Now, we can rewrite the expression:

1520 - (-16) - [37(356)(-540) + 405] - (349 - 64)

Step 5: Simplify the multiplications:
37(356)(-540) = -36,425,040

Step 6: Simplify the additions and subtractions:
1520 - (-16) - [-36,425,040 + 405] - (349 - 64)
1520 + 16 - [-36,424,635] - 285

Step 7: Simplify further:
1536 + 36,424,635 - 285
36,426,171 - 285
36,425,886

Therefore, the simplified form of the expression is 36,425,886.

The triangle ∆DEF is similar by the SSS similarly to the triangle ∆JKL

What are similar triangles

Similar triangles are two triangles that have the same shape, but not necessarily the same size. This means that corresponding angles of the two triangles are equal, and corresponding sides are in proportion.

To know if the triangles DEF and JKL are similar, we check if their sides corresponds in the same ratio, that is;

JK/DE = KL/EF = JL/DF

JK/DE = 9/12 = 3/4

KL/EF = 18/24 = 3/4

JL/DF = 12/16 = 3/4

The following cylinder has a volume of 627.8 cm3 and a height of 19.5 cm

What is the radius of the cylinder?

Use 3.14 for π and round your answer to the nearest tenth.

5.7
3.2
1.7
10.1

Answers

Answer:

Step-by-step explanation:

To find the radius of the cylinder, we can use the formula for the volume of a cylinder:

Volume = π * radius^2 * height

Given:

Volume = 627.8 cm^3

Height = 19.5 cm

π (pi) = 3.14

Substituting the given values into the formula:

627.8 = 3.14 * radius^2 * 19.5

Simplifying the equation:

627.8 = 60.93 * radius^2

To solve for the radius, we can divide both sides of the equation by 60.93:

radius^2 = 627.8 / 60.93

radius^2 = 10.29

Taking the square root of both sides:

radius ≈ √10.29

Rounding to the nearest tenth:

radius ≈ 3.2

Therefore, the approximate radius of the cylinder is 3.2 cm.

Answer:

3.2

Step-by-step explanation:

The volume of a cylinder is:

Vol = pi•r^2•h

Fill in what is given.

627.8 = pi•r^2•19.5

use 3.14 for pi.

627.8 = 3.14•r^2•19.5

simplify.

627.8 = 61.23r^2

divide by 61.23

10.253 = r^2

sqrt both sides

sqrt10.253 = r

3.2 = r

For which situations would it be appropriate to calculate a probability about the difference in sample means?

3) Both populations are skewed right. n1 = 5 and n2 = 10.
4) Population 1 is skewed right and population 2 is approximately Normal. n1 = 10 and n2 = 50.
5) Both populations have unknown shapes. n1 = 50 and n2 = 100.
6) Both populations are skewed left. n1 = 5 and n2 = 40.

Answers

It is generally appropriate to calculate a probability about the difference in sample means when the sample sizes are large (typically n ≥ 30) and the populations are approximately normally distributed.

How did we arrive at this assertion?

To determine if it is appropriate to calculate a probability about the difference in sample means, consider the assumptions and conditions for conducting a hypothesis test or constructing a confidence interval. The appropriateness of calculating a probability about the difference in sample means depends on the following factors:

1) Both population shapes are unknown. n1 = 50 and n2 = 100:

- It is generally appropriate to calculate a probability about the difference in sample means when the sample sizes are large (typically n ≥ 30) and the populations are approximately normally distributed. Since the population shapes are unknown in this case, it is difficult to assess this condition. However, the large sample sizes (n1 = 50 and n2 = 100) may suggest that it is reasonable to approximate the population distributions as normal. Therefore, calculating a probability about the difference in sample means could be considered.

2) Population 1 is skewed right and population 2 is approximately Normal. n1 = 50 and n2 = 10:

- In this case, the assumption of approximately normally distributed populations is violated for population 1, which is skewed right. When the population distributions are not approximately normal, it may not be appropriate to calculate a probability about the difference in sample means. The small sample size for population 2 (n2 = 10) may also limit the accuracy of any inference made based on this sample.

3) Both populations are skewed right. n1 = 5 and n2 = 10:

- Similar to the previous case, the assumption of approximately normally distributed populations is violated for both populations. Additionally, the small sample sizes (n1 = 5 and n2 = 10) may not provide sufficient information for reliable inferences. Therefore, it is generally not appropriate to calculate a probability about the difference in sample means in this situation.

4) Population 1 is skewed right and population 2 is approximately Normal. n1 = 10 and n2 = 50:

- Similar to case 2, the assumption of approximately normally distributed populations is violated for population 1, which is skewed right. In this case, the sample size for population 1 (n1 = 10) is also small, which may limit the accuracy of any inference made based on this sample. The larger sample size for population 2 (n2 = 50) might make it more reasonable to approximate the population distribution as normal. However, the violation of the assumption for population 1 suggests caution when interpreting the results. It is not generally appropriate to calculate a probability about the difference in sample means in this situation.

5) Both populations have unknown shapes. n1 = 50 and n2 = 100:

- Similar to case 1, the population shapes are unknown. However, the large sample sizes (n1 = 50 and n2 = 100) might suggest that it is reasonable to approximate the population distributions as normal. As mentioned before, calculating a probability about the difference in sample means could be considered in this case.

6) Both populations are skewed left. n1 = 5 and n2 = 40:

The assumption of approximately normally distributed populations is violated for both populations, as they are skewed left. Additionally, the small sample sizes (n1 = 5 and n2 = 40) may not provide sufficient information for reliable inferences. Therefore, it is generally not appropriate to calculate a probability about the difference in sample means in this situation.

Summarily, it is generally appropriate to calculate a probability about the difference in sample means when the sample sizes are large (typically n ≥ 30) and the populations are approximately normally distributed. However, when the population distributions are not approximately normal or when the sample sizes are small, it is generally not appropriate to calculate a probability about the difference in sample means.

Last year, 5 friends went to the beach. They each drank the same number of canned drinks and had 2 drinks left over. 2 friends could not come to the beach this year. The others brought the same number of drinks as last year and each drank equally as much as the year prior, this time ending with 8 drinks left over. How many beverages did each friend drink?

Answers

Each friend drank a total of 3 beverages during their visit to the beach.

Numerical calculation

To find the number of beverages each friend drank, let's assume the number of drinks they brought and consumed this year is represented by 'x'.

From the given information, we can set up the following equations:

Last year:

5x + 2 = Total number of drinks (equation 1)

This year:

3x + 8 = Total number of drinks (equation 2)

Since the total number of drinks should be the same in both years, we can set equation 1 equal to equation 2:

5x + 2 = 3x + 8

Now, let's solve this equation to find the value of 'x':

5x - 3x = 8 - 2

2x = 6

x = 3

So, each friend drank 3 canned drinks both last year and this year.

Therefore, each friend drank 3 beverages.

The surface area is cm Superscript 2

...

Answers

Answer:

348 cm²

Step-by-step explanation:

In this problem, we are asked to find the surface area of the regular hexagonal prism. We can use the formula:

[tex]SA = 2A + (P \cdot h)[/tex]

where [tex]A[/tex] is the area of the prism's hexagonal faces, [tex]P[/tex] is the perimeter of the hexagonal faces, and [tex]h[/tex] is the prism's height.

We can solve for the area of the hexagonal faces by splitting it into 6 triangles and multiplying the area of each triangle by 6.

[tex]A = 6\left(\dfrac{1}{2} bh\right)[/tex]

where [tex]b[/tex] is the triangle's base and [tex]h[/tex] is the triangle's height.

[tex]A = 6\left(\dfrac{1}{2}\cdot 4 \cdot 3.5\right)[/tex]

[tex]A = 6\left(2 \cdot 3.5\right)[/tex]

[tex]A = 12 \cdot 3.5[/tex]

[tex]A = 42\text{ cm}^2[/tex]

We can solve for the perimeter by multiplying one side length by 6.

[tex]P = 6(4) = 24\text{ cm}[/tex]

We are given that the height of the prism is 11 cm.

[tex]h = 11\text{ cm}[/tex]

Finally, we can solve for the surface area of the prism by plugging these values into the above formula.

[tex]SA = 2A + (P \cdot h)[/tex]

[tex]SA = 2(42) + (24 \cdot 11)[/tex]

[tex]SA = 84 + 264[/tex]

mean median mode

Answers

To determine which company has higher salaries, you can use the mean, median, or mode as measures of center. Let's calculate each of these measures for the given data:

Company A salaries: 45,000, 55,000, 53,000, 51,000, 49,000, and 42,000.

Mean (Average):

To calculate the mean, sum up all the salaries and divide by the total number of salaries.

Mean of Company A salaries = (45,000 + 55,000 + 53,000 + 51,000 + 49,000 + 42,000) / 6 = 295,000 / 6 = 49,167

Median:

To find the median, you arrange the salaries in ascending order and find the middle value. If there is an even number of values, you take the average of the two middle values.

Arranging the Company A salaries in ascending order: 42,000, 45,000, 49,000, 51,000, 53,000, 55,000

Median of Company A salaries = (49,000 + 51,000) / 2 = 50,000

Mode:

The mode represents the value(s) that appear most frequently in the dataset.

In Company A salaries, all the values occur only once, so there is no mode.

Now let's calculate the same measures for Company B salaries:

Company B salaries: 54,000, 39,000, 51,000, 52,000, 44,000, and 48,000.

Mean of Company B salaries = (54,000 + 39,000 + 51,000 + 52,000 + 44,000 + 48,000) / 6 = 288,000 / 6 = 48,000

Arranging the Company B salaries in ascending order: 39,000, 44,000, 48,000, 51,000, 52,000, 54,000

Median of Company B salaries = (48,000 + 51,000) / 2 = 49,500

Mode of Company B salaries = There are no repeating values, so there is no mode.

To summarize:

- Mean of Company A salaries: $49,167

- Median of Company A salaries: $50,000

- Mode of Company A salaries: No mode

- Mean of Company B salaries: $48,000

- Median of Company B salaries: $49,500

- Mode of Company B salaries: No mode

Based on these measures of center, we can see that the mean and median salaries of Company A are slightly higher than those of Company B. However, since there is no mode in either dataset, we cannot consider the mode as a determining factor in this case.

In one lottery, a player wins the jackpot by matching all five distinct numbers drawn in any order from the white balls (1
through 43) and matching the number on the gold ball (1 through 34). If one ticket is purchased, what is the probability
of winning the jackpot?

Answers

The probability of winning the jackpot with one ticket is P ( A ) = 1/34

Given data ,

To calculate the probability of winning the jackpot in the lottery, we need to determine the total number of possible outcomes (the sample space) and the number of favorable outcomes (winning outcomes).

Total number of possible outcomes:

For the white balls, there are 43 numbers to choose from, and we need to select 5 distinct numbers in any order. This can be calculated using the combination formula:

C(n, r) = n! / (r! * (n - r)!)

where n is the total number of options and r is the number of selections. In this case, we have 43 white balls and need to choose 5, so the number of possible outcomes for the white balls is:

C(43, 5) = 43! / (5! * (43 - 5)!) = 43! / (5! * 38!) = 43 * 42 * 41 * 40 * 39

For the gold ball, there are 34 numbers to choose from, and we need to select 1 number. So the number of possible outcomes for the gold ball is simply 34.

Therefore, the total number of possible outcomes is:

Total outcomes = (43 * 42 * 41 * 40 * 39) * 34

Number of favorable outcomes (winning outcomes):

To win the jackpot, we need to match all 5 distinct numbers from the white balls and the number on the gold ball. Since order doesn't matter for the white balls, we can use the combination formula again:

C(n, r) = n! / (r! * (n - r)!)

In this case, we have 43 white balls and need to choose 5, so the number of favorable outcomes for the white balls is:

C(43, 5) = 43! / (5! * (43 - 5)!) = 43 * 42 * 41 * 40 * 39

For the gold ball, there is only 1 winning number.

Therefore, the number of favorable outcomes is:

Favorable outcomes = (43 * 42 * 41 * 40 * 39) * 1

Probability of winning the jackpot:

The probability of winning the jackpot is the ratio of the number of favorable outcomes to the total number of possible outcomes:

Probability = Favorable outcomes / Total outcomes

Plugging in the values, we get:

Probability = [(43 * 42 * 41 * 40 * 39) * 1] / [(43 * 42 * 41 * 40 * 39) * 34]

Simplifying, we find:

Probability = 1 / 34

Hence , the probability of winning the jackpot with one ticket in this lottery is 1 in 34.

Match each event described to its probability.


( PLEASE ANSWER QUICK !!! )

Answers

The correct match are;

1 - 0.25

2 - 0.5

3 - 0.8

1) We must first evaluate the probability of each event before multiplying them together in order to predict the likelihood of receiving heads on a coin and an even number on a die.

Chance of flipping a coin heads:

The probability of receiving heads is 1/2 (or 0.5) because a fair coin has two equally likely outcomes (heads or tails).

Probability of rolling a die for an even number:

The probability of rolling an even number is 3/6 (or 1/2 or 0.5) since three of a fair die's six sides are even numbers (2, 4, and 6).

We sum the probabilities of the different events to determine the total probability:

P(Heads and Even) is defined as P(Heads) x P(Even) = 0.5 x 0.5 = 0.25, or 25%.

Therefore, the chance of rolling an even number on a die and receiving heads on a coin is 0.25, or 25%.

2) There are 26 red cards in a regular deck of cards out of a total of 52

As a result, the likelihood of earning a red card is:

P(Red card) = Red card count / total cards = 26 / 52 = 0.5 (or 50%).

Therefore, the chance of drawing one red card from a regular deck of cards is 0.5, or 50%.

3) The total number of marbles in the bag of 2 green, 8 yellow, 4 red, 3 blue, and 3 orange marbles is 2 + 8 + 4 + 3 + 3 = 20.

One can compute the likelihood of drawing a red marble as follows:

P(Red marble) = Red marble count / Total marble count = 4 / 20 = 0.2 (or 20%).

However, we are interested in determining the likelihood of NOT drawing a red marble.

Therefore, we deduct from 1 the likelihood of drawing a red marble:

Red marble: P(Not drawing one) = 1 - P(Red marble) = 1 - 0.2 = 0.8, or 80%.

Therefore, 0.8 or 80% of the time, no red marble will be drawn from the specified bag.

A: If there are 2 modes, what are the possible values of x?
B: If there is exactly one mode, write a possible value for x, and the mode.

Answers

Step-by-step explanation:

A: If there are 2 modes, x can be either 1 or 2.

B: To find the mode of the data set, we need to count how many times each number appears.

- 0 appears 2 times

- 1 appears 4 times

- 2 appears 4 times

- 3 appears 3 times

- 4 appears 1 time

Since both 1 and 2 appear 4 times in the data set, there are two modes.

For x, if we add it to the data set, then the mode must be x plus either 1 or 2.

If we choose x to be 2, then the mode would be 2, since 1 and 2 each appear 4 times, and adding another 2 would make it the mode.

So a possible value for x could be 2, and the mode would be 2.

The absolute value of any real number is always non-negative, meaning it is greater than or equal to zero. Therefore, the left side of the inequality, |x – 4|, will always be greater than or equal to zero.

Since the right side of the inequality, -3, is also greater than or equal to zero, this means that the inequality |x – 4| > –3 holds true for all real numbers x. In other words, there are no restrictions on the value of x.

The solution set for this inequality is the set of all real numbers, often represented as (-∞, +∞).

Answer:

(−∞,∞)

Step-by-step explanation:

|x – 4| > – 3

Since |x – 4| is always positive and - 3 is negative, |x – 4| is always greater than - 3, so the inequality is always true for any value of x.

All real numbers

The result can be shown in multiple forms.

All real numbers

So, the answer is (−∞,∞)

The value of variables in the figure is,

⇒ x = 80

⇒ y = 70

We have to given that;

By using given figure we have to find the value of each variable.

Now, We can formulate;

⇒ 55 = 1/2 (180 - y)

Solve for y;

⇒ 55 × 2 = 180 - y

⇒ 110 = 180 - y

⇒ y = 180 - 110

⇒ y = 70

And, The value of x is,

⇒ x = 180 - (60 + 40)

⇒ x = 180 - 100

⇒ x = 80

Thus, The value of variables in the figure is,

⇒ x = 80

⇒ y = 70

General Admission
$15 admission
$4 per taco

VIP
$36 admission
$1.50 per taco

How many tacos must Derrick buy for each pricing option to be the cheapest?

Answers

Answer:

Therefore, if Derrick wants to spend a maximum of $50 and he intends to buy a maximum of 8 tacos, then the general admission option is the cheapest. If he intends to buy 9 or more tacos, then the VIP option is the cheapest.

Step-by-step explanation:

To determine how many tacos Derrick must buy for each pricing option to be the cheapest, we can set up separate equations for each pricing option based on the total cost. Let's assume Derrick wants to spend a maximum of $50 on admission and tacos.

For the general admission option:

Total cost = 15 + 4x, where x is the number of tacos

We want to find the value of x that makes the total cost the same or less than $50:

15 + 4x ≤ 50

4x ≤ 35

x ≤ 8.75

For the VIP option:

Total cost = 36 + 1.5x, where x is the number of tacos

We want to find the value of x that makes the total cost the same or less than $50:

36 + 1.5x ≤ 50

1.5x ≤ 14

x ≤ 9.33

Answer:

x = -3y = 7

Step-by-step explanation:

You want to solve the system of equations ...

x +4y = 253x +y = -2

Solution

We can eliminate y by subtracting the first equation from 4 times the second:

  4(3x +y) -(x +4y) = 4(-2) -(25)

  11x = -33

  x = -3

Using the second equation, we have ...

  y = -2 -3x = -2 -3(-3) = 7

The values of x and y that make the equation true are ...

x = -3y = 7

If I have 7.55 how many dimes and quarters is it

Answers

Answer:

To convert 7.55 dollars into dimes and quarters, we need to make use of the fact that there are 10 dimes in a dollar and 4 quarters in a dollar. Here's how to do it:

Step-by-step explanation:

1. First, convert the dollar amount into cents: 7.55 dollars x 100 cents/dollar = 755 cents.

2. Next, use long division to find how many quarters are in 755 cents: 755 ÷ 25 = 30 with a remainder of 5.

3. The quotient of 30 tells us that we can use 30 quarters, which equals $7.50.

4. The remainder of 5 cents is less than a quarter, so we cannot use another quarter. Instead, we can use 1 dime, which is worth 10 cents.

Therefore, 7.55 dollars is equivalent to 30 quarters and 1 dime.

To determine the number of dimes and quarters you can make with $7.55, you need to consider the values of each coin and find a combination that adds up to the given amount.

Let's break it down:

1 dime = $0.10
1 quarter = $0.25

We'll assume you want to use the maximum number of coins possible.

To calculate the number of quarters, divide the total amount by the value of a quarter:

Number of quarters = $7.55 / $0.25 = 30.2

However, you can't have a fraction of a coin, so you'll need to round down to the nearest whole number. Therefore, you can have a maximum of 30 quarters.

To calculate the remaining amount after using all the quarters, subtract the value of the quarters from the total amount:

Remaining amount = $7.55 - (30 * $0.25) = $7.55 - $7.50 = $0.05

Now, we'll calculate the number of dimes. Divide the remaining amount by the value of a dime:

Number of dimes = $0.05 / $0.10 = 0.5

Again, you can't have a fraction of a coin, so you'll need to round down. Therefore, you can have a maximum of 0 dimes.

In summary, with $7.55, you can have a maximum of 30 quarters and 0 dimes.

Answers

Answer: 99 in²

Step-by-step explanation:

We can use the given formula for a triangular prism. We will substitute our known values and solve.

       Surface Area = length * base perimeter + (2 × base area)

       Surface Area = length * (1.5 in + 2 in + 2.5 in) + (2 × [tex]\frac{bh}{2}[/tex])

       Surface Area = 16 * (6 in) + (2 × [tex]\frac{(2\;in)(1.5\;in)}{2}[/tex])

       Surface Area = 16 in * (6 in) + (3 in²)

       Surface Area = 96 in² + 3 in²

       Surface Area = 99 in²

a bread making machine pours out 50 kg of mixture in 8 minutes in 8 minutes.at what rate is the mixture being poured?

Answers

To calculate the rate at which the mixture is being poured, we divide the amount of mixture poured (in kilograms) by the time it takes (in minutes):

Rate = Amount of mixture / Time

In this case, the amount of mixture poured is 50 kg, and the time taken is 8 minutes. Plugging these values into the formula, we have:

Rate = 50 kg / 8 min

Dividing 50 kg by 8 min gives us:

Rate = 6.25 kg/min

Therefore, the mixture is being poured at a rate of 6.25 kilograms per minute.
