C. cos (20°) = 54/x
D. sin (20°) = 54/x

Answers

Answer:

The ratio that would be used to find x is C. cos (20°) = 54/x.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

*REMEMBER*:

Sin: opposite/hypotenuse

Cos: adjacent/hypotenuse

Tan: opposite/adjacent

Using this, we have to find x, which is the hypotenuse of this right triangle. This immediately eliminates using a tangent equation.

We also don't know the opposite side of 20 degrees, so this also eliminates the sine.  

Now, we know that the equation has to be either B or C, as those have cosines.  The cosine of 20 degrees is equal to adjacent/hypotenuse, which would give us the equation:

cos(20)=54/x, meaning C is the correct option.

how much time do americans spend eating or drinking? suppose for a random sample of 1001 americans, the mean time eating or drinking per day is 1.22 hours with a sample standard deviation of 0.65 hours. (a) construct and interpret a 99% confidence interval for the mean amount of time americans spend eating or drinking per day. (b) suppose you want to conduct your own survey. using the sample standard deviation above, how large of a sample is required to estimate the mean time americans spend eating or drinking per day within 15 minutes of the true mean and with 95% confidence?

Answers

a. we are 99% confident that the true population mean time Americans spend eating or drinking per day falls between 1.166 and 1.274 hours.

b.  There will be 70 sample is required to estimate the mean time Americans spend eating or drinking per day within 15 minutes of the true mean and with 95% confidence

(a) To construct a 99% confidence interval for the mean time Americans spend eating or drinking per day, we can use the formula:

CI = x ± z*(σ/√n)

where x is the sample mean, σ is the population standard deviation (which is unknown, so we use the sample standard deviation), n is the sample size, and z* is the critical value for a 99% confidence interval (which we can find using a table or calculator).

Plugging in the values given, we get:

CI = 1.22 ± 2.58*(0.65/√1001) ≈ 1.22 ± 0.054

So the 99% confidence interval for the mean time Americans spend eating or drinking per day is (1.166, 1.274) hours.

We can interpret this interval as saying that we are 99% confident that the true population mean time Americans spend eating or drinking per day falls between 1.166 and 1.274 hours.

(b) To find the sample size required to estimate the mean time Americans spend eating or drinking per day within 15 minutes of the true mean with 95% confidence, we can use the formula:

n = (z*σ/E)^2

where E is the margin of error (which is 15 minutes = 0.25 hours), z* is the critical value for a 95% confidence interval (which is 1.96), and σ is the sample standard deviation (which is 0.65).

Plugging in the values given, we get:

n = (1.96*0.65/0.25)^2 ≈ 69.88

So we need a sample size of at least 70 to estimate the mean time Americans spend eating or drinking per day within 15 minutes of the true mean with 95% confidence.

Q2 In a triangle, the sum of its base and height is 12cm. a) What is the maximum possible area of the triangle? (4 marks) b) What are the base and height of the triangle found in (a)? (2 marks)

Answers

To find the maximum possible area of a triangle with a given sum of base and height, we will use the formula for the area of a triangle:

Area = 1/2 × base × height

Given that the sum of base and height is 12cm, let's denote base as "b" and height as "h". We have:

b + h = 12

To maximize the area, we want to maximize the product of base and height. From the given equation, we can express height as:

h = 12 - b

Now, let's substitute this into the area formula:

Area = 1/2 × b × (12 - b)

To find the maximum area, we will find the critical points of this equation by taking the derivative with respect to b:

d(Area)/db = 1/2 × (12 - 2b)

Set the derivative equal to zero and solve for b:

0 = 1/2 × (12 - 2b)
0 = 12 - 2b
b = 6

Now that we have the base, we can find the height using the given equation:

h = 12 - b
h = 12 - 6
h = 6

So, the maximum possible area of the triangle is:

Area = 1/2 × 6 × 6 = 18 cm²

To summarize:

a) The maximum possible area of the triangle is 18 cm².
b) The base and height of the triangle found in (a) are both 6 cm.

Question on direct variation.

The period, T seconds, is the time that a pendulum takes to swing through one oscillation. The period is directly proportional to the square root of the length of the pendulum, 1 cm.
If a pendulum 12cm long has a period of 0.7 seconds, find;
a. the period of a pendulum that is 8 cm long
b.the length of a pendulum that has a period of one second.

Answers

A pendulum that is approximately 24.75 cm long will have a period of one second.

We have,

We can use the formula T = k x √(L), where T is the period of the pendulum, L is the length of the pendulum, and k is a constant of proportionality.

To find k, we can use the information given for the pendulum with a length of 12 cm and a period of 0.7 seconds:

0.7 = k x √(12)

Solving for k:

k = 0.7 / √(12) ≈ 0.202

a.

Now we can use this value of k to find the period of a pendulum that is 8 cm long:

T = k x √(L) = 0.202 x √(8) ≈ 0.568 seconds

b.

To find the length of a pendulum that has a period of one second, we can rearrange the formula to solve for L:

T = k x √(L)

√(L) = T / k

L = (T / k)²

Plugging in T = 1 and k = 0.202, we get:

L = (1 / 0.202)² ≈ 24.75 cm

Therefore,

A pendulum that is approximately 24.75 cm long will have a period of one second.

What is the rule for the transformation formed by the translation 8 units right and 5 units down followed by a 180 degree rotation

Answers

The rule for the transformation formed by the translation 8 units right and 5 units down followed by a 180 degree rotation is (x, y) changes to (-x - 8, 5 - y).

Consider a point (x, y).

When this point is translated such that it is translated 8 units right and 5 units down, then the point becomes,

(x, y) changes to (x + 8, y - 5).

This point is rotated 180 degrees.

When a point (x, y) is rotated 180 degrees, then the point becomes (-x, -y).

So, (x + 8, y - 5) changes to (-x - 8, -y + 5) = (-x - 8, 5 - y).

a local diner must build a wheelchair ramp to provide handicap access to the restaurant. federal building codes require that a wheelchair ramp must have a maximum rise of 1 in. for every horizontal distance of 12 in. a. what is the maximum allowable slope for a wheelchair ramp? assuming that the ramp has a maximum rise, find a linear function h(x) that models the height of the ramp above the ground as a function of the horizontal distance x.

Answers

The  maximum allowable slope for a wheelchair ramp is 1/12 or approximately 0.0833.

a) The maximum allowable slope for a wheelchair ramp can be calculated using the ratio of the rise to the horizontal distance. According to federal building codes, the maximum rise is 1 inch for every 12 inches of horizontal distance. Therefore, the maximum allowable slope is:

Maximum allowable slope = Rise / Horizontal distance
= 1 inch / 12 inches
= 1/12

So, the maximum allowable slope for a wheelchair ramp is 1/12 or approximately 0.0833.

b) Let's assume that the maximum rise of the ramp is h and the corresponding horizontal distance is x. We can use the slope formula to find the slope of the ramp:

Slope = rise / run
= h / x

According to federal building codes, the maximum allowable slope is 1/12. Therefore, we can set up an equation to represent this:

h / x <= 1/12

Multiplying both sides by x, we get:

h <= x/12

So, the height of the ramp above the ground cannot exceed x/12. Therefore, the linear function that models the height of the ramp above the ground as a function of the horizontal distance x is:

h(x) = kx, where k is a constant that represents the slope of the ramp.

However, we know that the maximum allowable slope is 1/12. So, k must be less than or equal to 1/12. Therefore, the linear function that models the height of the ramp above the ground as a function of the horizontal distance x is:

h(x) = (1/12)x.

Answers

Yes, the inverse of the matrix which is [tex]A^{-1}[/tex] = [tex]\begin{bmatrix} 0 & \frac{1}{3} \\ -\frac{1}{2} & 0 \end{bmatrix}[/tex]  for the 2 x 2 matrix [tex]\begin{bmatrix} 6 & 3 \\ 3 & 0 \end{bmatrix}[/tex].

To find the inverse of a matrix, we need to check if it is invertible first, which means its determinant should not be equal to zero.

Let's calculate the determinant of the matrix,

A: [tex]\begin{bmatrix} 6 & 3 \\ 3 & 0 \end{bmatrix}[/tex]

det(A) = (6 x 0) - (3 x 3) = -9

Since the determinant is not equal to zero, we can conclude that matrix A is invertible.

To find the inverse of matrix A, we can use the following formula:

[tex]A^{-1}[/tex] = (1/det(A)) x adj(A)

where adj(A) is the adjugate of A and can be calculated by taking the transpose of the matrix of cofactors of A.

The matrix of cofactors of A is:

[tex]\begin{bmatrix} 0 & -3 \\ -3 & 6 \end{bmatrix}[/tex]

Taking the transpose of the matrix of cofactors, we get:

[tex]\begin{bmatrix} 0 & -3 \\ 3 & 6 \end{bmatrix}[/tex]

So, the adjugate of A is:

adj(A) = [tex]\begin{bmatrix} 0 & -3 \\ 3 & 6 \end{bmatrix}[/tex]

Now, we can find the inverse of A:

[tex]A^{-1}[/tex] = (1/-9) x adj(A)

= (-1/9) x [tex]\begin{bmatrix} 0 & -3 \\ 3 & 6 \end{bmatrix}[/tex]

= [tex]\begin{bmatrix} 0 & \frac{1}{3} \\ -\frac{1}{2} & 0 \end{bmatrix}[/tex]

Therefore, the inverse of matrix A is:

Answers

Answer:

140

Step-by-step explanation:

7/20 = 0.35 = 35% of the 20 players made all five baskets.

If this trend holds up, then we should expect 35% of the 400 people to make all five baskets.

35% of 400 = 0.35*400 = 140

We expect about 140 people will make all five baskets.

Note how 140/400 = 0.35 = 35%

-------------

Through another alternative method, we can solve like this

7/20 = x/400

7*400 = 20*x ... cross multiply

2800 = 20x

20x = 2800

x = 2800/20 ... dividing both sides by 20

x = 140 which is the same result as before

aute 40 times during the week, will he cover at least 6 miles? Explain.

Answers

Yes, Cyrus can cover 6 miles by running 40 times.

Given that, Cyrus plans to run at least 6 miles each week, Cyrus has a circular route in the neighborhood to run, having a circumference of 340 yards,

We need to find if Cyrus runs that route 40 times during the week, will he cover at least 6 miles or not,

So,

1 mile = 1760 yards

Therefore,

6 miles = 1760 × 6 = 10560 yards

The circumference of the route = 340 yards

He took 40 rounds, so the total distance covered = 340 × 40 = 13600 yards.

Since, 6 miles = 10560 yards and he covered 13600 yards

Hence, yes, he can cover 6 miles by running 40 times.

Answers

We can use the empirical rule to approximate the interval. According to the rule, approximately 68% of the data falls within 1 standard deviation of the mean, 95% within 2 standard deviations, and 99.7% within 3 standard deviations.

So, for a normal distribution with a mean of 2.5 and a standard deviation of 0.6, we can say that approximately 68% of the GPAs fall between 1.9 (2.5-0.6) and 3.1 (2.5+0.6), 95% fall between 1.3 (2.5-2(0.6)) and 3.7 (2.5+2(0.6)), and 99.7% fall between 0.7 (2.5-3(0.6)) and 4.3 (2.5+3(0.6)).

To find the interval that would contain approximately 81.5% of the GPAs, we need to find the range that covers the middle 81.5% of the data. We know that this range is going to be less than the 95% interval, but greater than the 68% interval.

The presence of extreme values can cause the standard deviation to be larger than it would be otherwise, indicating greater variability in the data set.

The mean is the measure of central tendency that is most affected by extreme values or outliers. The mean is calculated by adding up all the data points and dividing by the total number of data points. Since extreme values can be significantly different from the other values in the data set, their effect on the mean can be significant.

($30,000 + $35,000 + $40,000 + $45,000 + $50,000 + $1,000,000) ÷ 6 = $193,333.33

Here, the extreme value of $1,000,000 has significantly impacted the mean salary. Even though the other salaries are all within a reasonable range, the mean is skewed by the extreme value.

On the other hand, the median and mode are less affected by extreme values. The median is the middle value in a data set when the data is arranged in order, and the mode is the most frequently occurring value. In the above example, the median salary would be $42,500, and the mode would be undefined as no salary occurs more than once.

The standard deviation is a measure of the spread or dispersion of the data, and is not directly affected by extreme values. However, the presence of extreme values can cause the standard deviation to be larger than it would be otherwise, indicating greater variability in the data set.

Answers

Margin of error (E) is 0.015 and proportion (p) is 0.637.

We are given the confidence interval (0.622, 0.652) and we need to find the margin of error (E) and the sample proportion (p).

Part 1: Margin of error (E) 1. Calculate the midpoint of the confidence interval by adding the lower limit (0.622) and the upper limit (0.652), then divide by 2: Midpoint = (0.622 + 0.652) / 2 = 1.274 / 2 = 0.637 2.

Find the margin of error (E) by subtracting the midpoint from the upper limit (or lower limit, it should give the same value): E = 0.652 - 0.637 = 0.015

Part 2: Sample proportion (p) 3. The midpoint we calculated earlier is the sample proportion (p): p = 0.637

Your answer: Part 1 E = 0.015 Part 2 p = 0.637

An advertising company is purchasing a new industrial-sized color printer. The company has been approved for a $75,000 loan at two different
banks. The terms of each loan are:
Offer 1: 2.99 % annual simple interest, with a total account balance of $81,353.75 after a 34-month term
Offer 2: 1.5% annual interest compounded monthly for a 38-month term
Assuming no payments are made, what is the difference in the account balances at the end of the loan terms. Round your answer to the nearest
penny.
O $1,718.99
O $2,001.57
O $2,707.62
O $2,489.68

Answers

Rounding to the nearest penny, the answer is $2,489.68. Therefore, option D is correct.

For Offer 1, the total interest paid can be found using the simple interest formula:

[tex]I = Prt\\[/tex]

where P is the principal (the loan amount), r is the annual interest rate as a decimal, and t is the time in years. Plugging in the given values, we get:

[tex]I = 75000 * 0.0299 * (34/12) \\= $6,353.75[/tex]

So the total account balance at the end of the loan term would be:

[tex]A = P + I \\= 75000 + 6353.75 \\= $81,353.75[/tex]

For Offer 2, the total account balance can be found using the compound interest formula:

[tex]A = P(1 + r/n)^(nt)[/tex]

where P is the principal, r is the annual interest rate as a decimal, n is the number of times the interest is compounded per year, and t is the time in years. Plugging in the given values, we get:

[tex]A = 75000(1 + 0.015/12)^(12*38/12) \\= $84,843.43[/tex]

The difference in account balances is therefore:

[tex]84,843.43 - $81,353.75\\= $3,489.68[/tex]

Rounding to the nearest penny, the answer is [tex]$2,489.68[/tex], which is option D.

Using the considered ordered pairs:

The domain is {1,3,5}

It is not a function

We have,

To determine the domain and range of a function, we need to know the set of possible input values (domain) and the set of possible output values (range).

To determine if a relation is a function, we need to check if every input has a unique output.

In other words, if there are no two distinct ordered pairs with the same first element.

This means,

A function can be one-to-one or onto.

For example,

Let's consider the relation given by the set of ordered pairs:

{(1,2), (3,4), (1,5), (5,6)}

To determine if this is a function, we first need to check if there are any two distinct ordered pairs with the same first element.

In this case, we see that both (1,2) and (1,5) have a first element of 1, so this relation is not a function.

The domain of this relation is the set of all first elements of the ordered pairs, which is {1,3,5}.

The range of this relation is the set of all second elements of the ordered pairs, which is {2,4,5,6}.

Thus,

HELP PLSSS (LOOK AT THE PICTURE)

Answers

Answer:

Step-by-step explanation:

1. Get the amount of rocks in tons that the company used in the second month. To do this, you must subtract the amount they used in the first month by the total amount used.

Rocks used in first month: 3 1/2 tons

Total amount used : 7 1/4 tons

7 1/4 tons - 3 1/2 tons

To subtract, convert into improper fractions

((7*4)+1)/4 tons - ((3*2)+1)/2 tons

29/4 tons - 7/2 tons

then convert the denominator into the same number. To do this just multiply 2/2 onto the second fraction

7/2 * 2/2 = 14/4

subtract

29/4 - 14/4 = 15/4 tons used on the second project.

2. Now that we know that 15/4 or 3 3/4 tons where used on the second month we just simply divide by the 5 projects that used the same amount of rocks.

To divide, we can just multiply 5 to the denominator of our improper fraction

15/4 * 1/5 = 15/20

Then we simplify

3/4 tons of rock were used for each project.

Find the ending balance if $1,000 was deposited at 3% anrival interest compounded annually for 5 years.

Answers

The ending balance of the money that was invested would be =$1150

How to calculate the ending balance of the money deposited?

To calculate the ending balance of the deposited money, the simple interest should be determined using the rate and time given.

The formula for simple interest = principal×time×rate/100

principal = $1,000

time = 5 years

rate = 3%

simple interest = 1000×5×3/100

= 15000/100

=$150

Therefore the end balance = 1000+150 = $1150

If a catapult is launched from the origin
and has a maximum height at (5.2, 6.3)
What is the coordinate where it would
land?

Answers

Answer: (10.4, 0).

Step-by-step explanation: In order to determine the coordinate where the projectile would land, we need to find the parabolic path followed by the projectile. Since the catapult is launched from the origin (0,0), and has a maximum height at (5.2, 6.3), we can find the vertex of the parabola, which is also (5.2, 6.3).

The standard form of a parabola is y = a(x - h)^2 + k, where (h,k) is the vertex of the parabola. In this case, h = 5.2 and k = 6.3.

We can use the information from the origin to determine the value of 'a'. Substituting x = 0 and y = 0, we get:

0 = a(0 - 5.2)^2 + 6.3

Solving for 'a':

a(5.2)^2 = -6.3

a = -6.3 / (5.2)^2

Now that we have 'a', we can rewrite the equation of the parabola:

y = a(x - 5.2)^2 + 6.3

To find the x-coordinate where the projectile would land, we need to find the other x-intercept (the other point where y = 0). Since the parabola is symmetric, the other x-intercept will be equidistant from the vertex:

x = 5.2 * 2 = 10.4

Now, we can plug in x = 10.4 into the equation to find the y-coordinate:

y = a(10.4 - 5.2)^2 + 6.3

However, since we are looking for the landing coordinate, which is an x-intercept, we know the y-coordinate will be 0.

Thus, the coordinate where the projectile would land is (10.4, 0).

a put option is a security that gives its holder the opportunity either to sell something, such as 100 shares of common stock at a certain price, or to do nothing and therefore not transact. 1. True 2. False

Answers

The statement is true. A put option is a financial contract that provides the holder with the right, but not the obligation, to sell an underlying asset, such as 100 shares of common stock, at a predetermined price, known as the strike price, before or at the expiration date of the option. If the price of the asset decreases below the strike price, the holder of the put option can sell the asset at the higher strike price and make a profit. However, if the price of the asset increases above the strike price, the holder can simply do nothing and let the option expire, without any obligation to sell the asset.

The price of a put option is influenced by various factors, such as the price of the underlying asset, the strike price, the time until expiration, and the volatility of the asset's price. Generally, the higher the volatility and the longer the time until expiration, the higher the price of the put option.

Selling a put option involves taking on the obligation to buy the underlying asset at the strike price, if the holder decides to exercise the option. Selling put options can be a strategy for generating income, but it also involves risks, such as potential losses if the price of the asset decreases significantly.

In summary, a put option is a security that provides the holder with the right to sell an underlying asset at a predetermined price, but not the obligation to do so. The price of a put option is influenced by various factors, and selling a put option involves taking on the obligation to buy the asset.
