Answer is D

if you want to get the area of a triangle you have to multiply the base times height and than divide by 2

A= 1/2 bh
A=1/2 (7x6)
A= 1/2(42)
A= 21

and for the area of the rectangle it’s 42 since there’s no dividing

A=bh
A=7x6
A=42

Answer:

197

Step-by-step explanation:

Sample proportion is; p^ = 12/50 = 0.24

Margin of error of 5% is given by the formula;

ME = (z_0.05) √[p^(1 - p^)/n]

Let's make n(number of sample) the subject.

n = ((z_0.05)/ME)²((p^)(1 - p^))

From tables, the z-score of 0.05 is 1.645

Thus;

n = ((1.645)/0.05)²(0.24(1 - 0.24))

n ≈ 197

What is the difference between the mean and the median of the data set?

natka813 [3]

Answer:

Your answer is 0 (zero).

Step by Step Explanations:

For mean:

1. Add all the numbers; which is 90

2. Divide by how numbers there are, for this case there are 6 numbers; 90/6 = 15

3. Your mean is 15

For Median:

1. Order the numbers from lest to greatest. Ex: 8, 10, 12, 18, 20, 22

2. Find the middle number(s), which are 12 &18

3. Add; 12 + 18 = 30

4. Divide; 30/2 =15

5. Your Median is 15

So now the question asks "what's the difference?" which means subtraction: 15 - 15 = 0
