Answers

Answer 1

Answer:

189 seconds

Step-by-step explanation:

16% shorter,

Left side first and second group is 2.5% and 13.5% = 16%

189 is the max of that group

Answer 2

16% of videos on the streaming site are shorter than 189 seconds.

To determine the length at which 16% of videos are shorter, we can use the properties of a normal distribution.

Given that the mean length is 264 seconds and the standard deviation is 75 seconds, we can use a Z-score to find the corresponding percentile.

First, we need to find the Z-score associated with the 16th percentile. This can be done using a Z-table or a statistical calculator. The Z-score corresponding to the 16th percentile is approximately -0.9945.

Using the formula for Z-score:

Z = (X - μ) / σ,

where X is the length of the video, μ is the mean, and σ is the standard deviation, we can rearrange the formula to solve for X:

X = Z * σ + μ.

Substituting the values:

X = (-0.9945) * 75 + 264,

X ≈ 189 seconds.

Therefore, approximately 16% of videos on the streaming site are shorter than 189 seconds. So, the correct answer is 189 seconds.

Answers

Answer:

The responses to the given question can be defined as follows:

Step-by-step explanation:

Its color palette depends on how much radiation reaches the eyes or the intensity of it. If indeed the duration of a wave is less than 400 nm, it is called UV and much more than 750 nm simple pleasures light it is (IV). The shorter wavelength implies a much more frequent spectrum and lower frequencies are the longer wavelengths.

The shorter the distance, the higher it's indeed. Since the red duration has been longer, the intensity is low. The purple has a smaller range and a high frequency, on the other side. The wavelengths are shorter as well as the frequencies are lower than the red, and it will differ even as violet goes, Remember that even more power is provided with the longer the duration of color. That wave/frequency color rises and is longer the purple color is becoming the lowest color.

Is x=2 a solution to the equation below?
4(x-1)-3(x-2)=-8

Answers

Answer:

Step-by-step explanation:

To find out if 2 is a solution, replace all the x's with 2.

4(2 - 1) - 3(2 - 2) =8

4(1) - 3(0) = 8

4 - 0 = 8

4 = 8

Nope! False! 2 is not a solution.

Which expression is equivalent to 54n

Answers

Answer:

Choice A, 20(3n-m)

Step-by-step explanation:

First, lets combine like terms for the question 54n - 20m + 6n,

60n - 20m.

Next, lets rule out the choices that are visibly wrong. This includes Choice B, because it wouldn't equal what is above and Choice C, as it ignores unlike terms.

Now, it is down to Choices A and D. Let's use the distributive property to simplify these options.

Choice A:

20(3n-m)

60n-20m

Choice D:

20(m-3n)

20m-60m

With this, it can be concluded that the correct answer is Choice A since it equals 60n-20m, which is equal to the original question when like terms are combined.

the true mean SAT score of the graduating high school seniors.

Answers

Answer:

Step-by-step explanation:

Confidence interval :

Mean score ± margin of error

Margin of Error = 21

Mean SAT score = 447

Hence,

447 ± 21

Lower boundary = 447 - 21 = 426

Upper boundary = 447 + 21 = 468

Find the maximum value of y = -x^2 + 6x + 5

Answers

the answer is C, you use the formula x=-b/2a

Answer:

Step-by-step explanation:

The maximum value is the y- coordinate of the vertex

Given a quadratic in standard form , y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = - x² + 6x + 5 ← is in standard form

with a = - 1 and b = 6 , then x- coordinate of vertex is

x = - [tex]\frac{6}{-2}[/tex] = 3

Substitute x = 3 into the function for y- coordinate of vertex

y = - 3² + 6(3) + 5 = - 9 + 18 + 5 = 14

maximum value is 14 → D

Mrs. James is making snow cone cups using a special-coated paper to sell at a school
fundraiser. The snow cone cups have a diameter of 4 inches across the widest part of the
snow cone and are 5 inches tall.
What value most closely represents the amount of coated paper in square inches that Mrs.
James will need to make 150 snow cone cups?

Answers

Answer:

6957 inches squared

Step-by-step explanation:

surface area of a cone = πr × (r + √[h² + r²])

h = height

r = radius = 4/2 = 2 inches

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

(3.14 x 2) x (2 + √5² + 2²) = 6.28 x 7.39 = 46.38 inches squared

the amount of coated paper needed for 1 cup is 46.38 inches squared

Amount needed for 150 cups = 46.38 x 150 = 6957

x 150
