Using the Central Limit Theorem, it is found that the sampling distribution of the sample proportion of the 50 questions on which you get the correct is approximately normal, with mean of 0.7 and standard error of 0.0648.

It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].

In this problem, we have that p = 0.7, n = 50, hence the mean and the standard deviation are given as follows:

[tex]\mu = p = 0.7[/tex]

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.7(0.3)}{50}} = 0.0648[/tex]

Answer:

36

Step-by-step explanation:
36 x 3.14 = 113.04

Since to find a diameter from the area, you need to divide by 3.14

113.04 divided by 3.14 = 36


But since its already there you can just figure out that 36 is the diameter and you don't have to do any calculating

Answer:

The answer would be 17

Step-by-step explanation:

Answer:

x = 17

Step-by-step explanation:

Pythagorean Theorem: a^2 + b^2 = c^2

15^2 + 8^2 = c^2 (15^2 = 225 and 8^2 = 64)

225 + 64 = 289

[tex]\sqrt{289}[/tex] = 17

The value of z using the information and the formula provided in the question is -5.292.

Subsituting for the missing values in the formula, the formula becomes: [tex]\frac{130 - 135}{\frac{5}{\sqrt{28} } }[/tex]

Solving for the numerator, the number becomes -5. Solving for the denominator, the number becomes 0.94491

z = -5/0.94491

z = -5.292

2) 274.89

Step-by-step explanation:

Find the volume and surface formulas for each shape attached.

I'll do a couple for you. For rest just use the formulas and input the values and solve.

1) It is a pyramid.

V  = 1/3 * b * h, where b is the area of base, which is a rectangle so,

b = l * w

so,

V = 1/3 * l * w * h

V = 1/3 * 8 * 21 * 13

V = 1/3 * 2184

V = 2184 / 3

V = 728

2) It is a cylinder

[tex]V = \pi *r^2*h[/tex]

V = π * 5^2 * 3.5

V = π * 25 * 3.5

V = 87.5 π

V = 274.89

Step-by-step explanation:

the scaling ratio is 12/20 = 3/5.

this always applies only to one-dimensional distances, lengths.

the perimeter is calculated as the sum of individual lengths. so while each length is scaled by the same ratio, also the sum is then scaled by that ratio.

p_old = a + b + c

p_new = ra + rb + rc = r(a + b + c) = r×p_old

so, the ratio for the perimeter is also 3/5.

for the area this is a bit different, as an area is always calculated by multiplying 2 lengths (other unscaled factors can be ignored for that consideration of relative change), and that means the scaling ratio has to be multiplied in twice.

a_old = a × b

a_new = ra × rb = r² × a×b = r² × a_old

so, the ratio for the area is

(3/5)² = 9/25

In short: y = 4(L)

Answer:

If you would like to solve x^3 - 3 * y when x = - 3 and y = 4, you can do this using the following steps:

x = - 3

y = 4

x^3 - 3 * y = (-3)^3 - 3 * 4 = -27 - 12 = - 39

The correct result would be A -39.

Answer:

25%

Step-by-step explanation:

The fraction of coins which are pennies

= 9/36

= 1/4.

As a percent this is 1/4 * 100

= 25%.

There is a probability of 22.66% that their average catch is less than 31.5 pounds

The z score is used to determine by how many standard deviations the raw score is above or belaw the mean. It is given by:

z = (raw score  - mean)/ (standard deviation ÷ √sample)

Given that, mean = 32, std = 4, sample = 36, hence:

For 31.5:

z = (31.5 - 32) / (4 ÷√36) = -0.75

P(z < -0.75) = 0.2266

There is a probability of 22.66% that their average catch is less than 31.5 pounds
