A.) 7/2 is greater than the 5/2, so it is located above 5/2. Hence, the statement is False.

B.) -1 1/4 is lower in magnitude with -ve sign so it would be above in the vertical line. So, the statement is True.

C.) -4/5 is obviously in the bottom, 'cause of the negative sign.

D.) 3 2/7 is in the above 'cause of it's positive sign as compared to the other one

In short, Your Answer would be: Option B

Hope this helps!

A. False - 7/2 is more than 5/2 and the number line gets bigger as it goes up so 7/2 is above 5/2

B. True - the numbers get bigger as they go down on the negative side of the number line so -1 1/4 is above -1 3/4

C. and D are both False because the positive numbers are above the negative numbers

Hope that helps

Answer:

x=125º

2x=250º

Step-by-step explanation:

720 is the sum of the interior angles of a Hexagon

720=60+65+120+100+3x

720=345 +3x

-3x=345-720

-3x=-375

-x=-125

x=125

mezya [45]

Complete question is;

Suppose we are testing the null hypothesis H0: μ = 20 and the alternative Ha: μ ≠ 20, for a normal population with σ = 5. A random sample of 25 observations are drawn from the population, and we find the sample mean of these observations is x¯ = 17.6. The P-value is closest to:

a. 0.0668.

b. 0.0082.

c. 0.0164.

d. 0.1336

Answer:

Option D

Step-by-step explanation:

We are given;

Null hypothesis; H0: μ = 20

Alternative hypothesis; Ha: μ ≠ 20

Population Standard deviation; σ = 5

Sample size; n = 25

Sample mean; x¯ = 17.6

Let's find the z-score from the formula;

z = (x¯ - μ)/(σ/√n)

z = (17.6 - 20)/(5/√5)

z = - 1.073

From online p-value from z-score calculator attached, using z = -1.073; two tailed hypothesis; significance value of 0.05,we have;

The P-Value is 0.283271.

Looking at the given options, the closest to the p-value is option D
