A food company sells its corn flakes in boxes of two different sizes: the regular box and the family value box. For the family value box, the length, width, and height of the box have all been increased by 25%

By what percentage does the volume of the box increase from the regular box to the value box? Round your answer to the nearest percent.

Answer:

14336

Step-by-step explanation:

the general term is:

s(n) = 7*(2)^(n-1)

you can check it by plugging in some number:

s(3) = 7*2^(3-1) = 7*4 = 28

s(4) = 7*2^(4-1) = 7*8 = 56

The 12th term is:

s(12) = 7*2^(12-1) = 7*2^11 = 7*2048 = 14336

The equation represented in the graph shown is,

⇒ y = x² - 2x - 8.

Now, We know that the parabola goes down from the left and passes through the point (-2,0),

then goes to a minimum of (1,-9), and then goes up to the right through the point (4,0).

Hence, We can use this information to determine the equation of the parabola in vertex form, which is,

⇒ y = a(x - h)² + k

where (h, k) is the vertex of the parabola.

Step 1: Finding the vertex We already know the vertex of the parabola is (1,-9) because it is given in the problem.

Therefore, h = 1 and k = -9.

Step 2: Finding the value of "a" To find the value of "a", we can use one of the points on the parabola (either (-2,0) or (4,0)).

Let's use the point (-2,0).

When x = -2, y = 0.

Therefore, we can substitute these values into the vertex form equation and solve for "a":

0 = a(-2 - 1)² - 9

0 = a(-3)² - 9

0 = 9a - 9

9 = 9a

a = 1

Therefore, the value of "a" is 1.

Step 3: Writing the equation in vertex form Now that we know the vertex (h, k) and the value of "a", we can write the equation in vertex form:

y = 1(x - 1)² - 9

Simplifying this equation gives us:

y = x² - 2x - 8

Therefore, the equation represented in the graph shown is option (a) y = x² - 2x - 8.

To find the percentile for the data value 121 in the given data set, we need to follow these steps:

Step 1, Sort the data set in ascending order.

111 111 112 113 113 115 115 115 117 118 119 119 121 123 127 129

Step 2, Calculate the rank of the data value 121 in the sorted data set.

The rank of 121 is the position of 121 in the sorted data set. Counting from left to right, we see that 121 is the 12th value in the sorted data set.

6.[tex]P = (4x -28) yds[/tex], [tex]A= (x-7)yds^2[/tex]

Step-by-step explanation:

5) Because the figure is a square then the diagonal splits the shape into two isosceles right triangles then the triangles are 45° 45° 90° triangles and the rule for such triangle is that the hypotenuse(in this case 4) is equal to a leg ·√2  so to find the leg we divide the hypotenuse by √2 so

4/√2 which is approximately 2.83 which when rounded to the nearest tenth is 2.8

so x = 2.8 cm

And because the figure is a square the perimeter is the length if a side times four so

P= 2.8(4)

P = 11.2 cm

A= 2.8(2.8)

A = 7.84cm^2 which when rounded to the nearest tenth is 7.8cm^2

6) This figure is also a square so the same rules apply for finding perimeter and area so

P = 4(x-7)

P = 4x - 28

P = (4x -28) yds

A = (x - 7)(x-7) which would just be A=(x-7)yds^2 or we could expand our answer

the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches ) and to the left end of the x-axis (as x approaches

The length of AB, x is 2.414 units.

Let's call the length of the square's side x. Then, the hypotenuse of each triangle is the diagonal of the square, which has length x√2.

Let's consider one of these triangles, say triangle APC. We can use the Pythagorean theorem to find the length of PC:

PC² = AP² + AC²

PC² = 1² + x²

PC = √(1+x²)

Since triangle APC is isosceles, we know that angle APC is 45 degrees. Therefore, angle CPB is also 45 degrees, since it is the supplement of angle APC. Similarly, angle BPC is 90 degrees, since it is the sum of angles CPB and BPA.

We can now use the sine rule in triangle BPC to find the length of BP:

sin(BPC) / BP = sin(CPB) / x√2

sin(90°) / BP = sin(45°) / x√2

BP = x / √2

Since AP = BP = CP = 1, we have:

1 + x / √2 + √(1+x²) = x

Solving this equation for x gives:

x ≈ 2.414

Therefore, the length of AB is approximately 2.414 units.

Decreasing confidence level or increasing sample size decreases width of confidence interval. Undercoverage cannot be adjusted after sampling.

Define sampling ?

Sampling is the process of selecting a subset of individuals or units from a larger population to estimate characteristics of the population.

(a) If the confidence level were decreased from 95% to 90%, the width of the interval would decrease. This is because a lower confidence level requires a smaller margin of error, which is the product of the critical value and the standard error of the proportion.

(b) If the sample size were increased from 50 to 200 students, the width of the interval would decrease. This is because as the sample size increases, the standard error of the proportion decreases, resulting in a smaller margin of error and a narrower confidence interval.

(c) The physician cannot adjust the confidence interval to take undercoverage into account after the sample has been collected. Undercoverage is a type of sampling bias that occurs when some members of the population are less likely to be included in the sample than others. Adjusting the confidence interval would require information about the characteristics of the missing 30% of freshmen, which is unknown. The best way to address undercoverage is to try to improve the sampling method in future studies, such as by using stratified sampling to ensure that all subgroups of the population are represented in the sample.

When the odds against an event are given as "a:b", the probability of the event can be found by using the formula:

Probability of the event = b / (a + b)

In this case, the odds against the event are 3:7, which means that the probability of the event not occurring is 3/(3+7) or 3/10. Therefore, the probability of the event occurring is:

1 - 3/10 = 7/10

So the probability of the event is 7/10 or 0.7 (70%) when the odds against the event are 3:7.

In order to simulate the amount of bullseyes that Grace will strike during her upcoming turn, we can carry out the following steps:

Set up a loop which will execute the simulation for a predetermined number of rounds. Let's say that we wish to conduct 10,000 rounds as an example.

Within each cycle of the loop, mimic every round by generating 5 random numbers between 0 and 1 – signifying the likelihood of hitting a bullseye with each projectile.

For each round, accumulate the total number of bullseyes achieved by summing together the resultant quantity of times when the generated figure is less than or equivalent to 2/3.

Subsequent to the successful running of the simulation through the 10,000 rounds, calculate the average number of bullseyes struck in per round basis by dividing the complete amount of bullseyes hit with 10,000.

Finally, express the projected amount of bullseyes that Grace is anticipated to hit within her successive turn, by stating the average attained from step 4.

Consequently, with judicious repeating of multiple rounds, our calculation can factor in the differential element instinctive within this process and finally acquire a more precise tally of the estimated number of bullseyes Grace could potentially hit during her impending turn.

What are place values?

Place values describe a digit's location within a number and the value that digit represents based on that location. Each digit in a number is given a place value in our decimal number system according to where it is from the rightmost side. The first position to the right is known as the one's place, followed by the tens place, hundreds place, thousands place, and so on, with each position to the left denoting ten times the value of the position to its immediate right.

The new set of numbers is produced by substituting the number 9 for the previous ones:

7989, 9456, 4592, 3972

We can see that 9 is the greatest digit by comparing the leftmost digit of each integer to itself. Due to the absence of a 9 in the leftmost digit, we can rule out alternatives 7989 and 3972.

Second from the left is then put up for comparison. The number is four in both 9456 and 4592. The 5 in 9456, on the other hand, is greater than the 5 in 4592 and is the next digit to the right in the number. As a result, option 4592 can be disregarded.

And that leaves 9456 and 7989 for us to work with. 9 in the number 9456 is the leftmost digit, which is greater than 7 in the number 7989. In both 9456 and 7989, the second digit is 4, making them the same. 9456's third digit, however, is 5, which is larger than 7989's eighth digit, which is 8. The biggest number,

The probability that two red and two blue balls were transferred from the first urn to the second urn is 0.27 (approx).

What is probability ?

Probability is a measure of the likelihood or chance of an event occurring. It is a mathematical concept that ranges from 0 (indicating an impossible event) to 1 (indicating a certain event).

Let R1 be the event that the first ball drawn from the first urn is red, and let B1 be the event that the first ball drawn from the first urn is blue. Similarly, let R2 and B2 be the events that the second and third balls drawn from the first urn are red and blue, respectively. Finally, let B be the event that a blue ball is drawn from the second urn.

We want to find P(R2=2, B2=2 | B), the probability that two red and two blue balls were transferred from the first urn to the second urn, given that a blue ball was drawn from the second urn.

By Bayes' theorem, we have:

P(R2=2, B2=2 | B) = P(B | R2=2, B2=2) * P(R2=2, B2=2) / P(B)

To find each of these probabilities, we can use the following:

P(R2=2, B2=2) = (5 choose 2) * (3 choose 2) / (8 choose 4) = 15/56, which is the probability of selecting 2 red and 2 blue balls from the first urn.

P(B | R2=2, B2=2) = 2/4 = 1/2, which is the probability of drawing a blue ball from the second urn, given that 2 red and 2 blue balls were transferred from the first urn.

P(B) = P(B | R2=0, B2=4) * P(R2=0, B2=4) + P(B | R2=1, B2=3) * P(R2=1, B2=3) + P(B | R2=2, B2=2) * P(R2=2, B2=2), which is the total probability of drawing a blue ball from the second urn.

To find P(R2=0, B2=4), we need to use the complement rule:

P(R2=0, B2=4) = 1 - P(R2=1, B2=3) - P(R2=2, B2=2)

To find P(R2=1, B2=3), we can use:

P(R2=1, B2=3) = (5 choose 1) * (3 choose 3) / (8 choose 4) = 5/56

Substituting all these values into Bayes' theorem, we get:

P(R2=2, B2=2 | B) = (1/2) * (15/56) / P(B)

To find P(B), we can use the law of total probability:

P(B) = P(B | R2=0, B2=4) * P(R2=0, B2=4) + P(B | R2=1, B2=3) * P(R2=1, B2=3) + P(B | R2=2, B2=2) * P(R2=2, B2=2)

Substituting the values we found earlier, we get:

P(B) = (0/4) * (1 - 5/56 - 15/56) + (1/4) * 5/56 + (2/4) * 1/2 = 0.27 (approx)

Answer:

Please mark me the brainliest. It took me a lot of time to answer this question.

Step-by-step explanation:

To solve this problem, we can use trigonometry. We know that the length of the train track through the mountain is 1600 feet and that the angle it makes with the horizontal is 1.1. Let's call the change in elevation from one end of the tunnel to the other "h".

We can use the tangent function to find "h", which is defined as the opposite side (the change in elevation) divided by the adjacent side (the length of the train track through the mountain). In this case, the tangent of the angle 1.1 is equal to h divided by 1600:

tan(1.1) = h/1600

To solve for "h", we can multiply both sides by 1600:

h = 1600 * tan(1.1)

Using a calculator, we can find that tan(1.1) is approximately 0.0192. Therefore:

h = 1600 * 0.0192

h = 30.72 feet

So the change in elevation from one end of the tunnel to the other is approximately 30.72 feet.

Probability is the study of the chances of particular outcomes in a set of given circumstances. It is used to measure the likelihood of an event occurring, and it is expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. Probability can also be expressed as percentages, fractions, or decimals. Probability is used in many fields, including mathematics, finance, engineering, and science.

P(B) = 0.20

P(-B) = 0.80

P(No Play | B) = 0.20

P(No Play | -B) = 0.95

a) P(No Play) = P(No Play | B)*P(B) + P(No Play | -B)*P(-B)

= 0.20*0.20 + 0.95*0.80 = 0.76

b) P(Store Bought | No Play) = P(No Play | B)*P(B) / P(No Play)
