The points on the number line are -6 and 2.

2 - -6 = 4

2 + 6 = 4

A is not the answer.

--6 - 2 = 8

+6 - 2 = 4

B may be the answer.

-6 - 2 = -8

C is not the answer.

-2 - -6 = 4

-2 + 6 = 4

D is not the answer.

<h3>The answer is B) The value of -a - 6 is positive.</h3>

Let me know if this is the correct answer. :)

In a recent survey, 72 out of 100 consumers reported that they preferred plastic bags instead of paper bags for their groceries.

kupik [55]

Answer:

a) P=0.03

b) α=0.05

c) 0.72

d) 100

e) 0.72

Step-by-step explanation:

a) The P-value is the probability of the sample result. In this case the P-value is 0.03.

b) The level of significance is the threshold of probabilty for the null hypothesis to be reejcted or not. It is contrasted with the P-value to know if the effect is significant. In this case, the level of significance is 0.05.

NOTE: if it is a two-side test, the level of significance is 0.1 (two times 0.05).

c) The sample proportion is the one that results from the sample data. In this case, the sample proportion is 0.72.

$p=72/100=0.72$

d) The sample size is the amount of consumers reported. In this case is 100 customers.

e) The null value is 0.72 (equal to the sample proportion), because it is tested if there is no difference between the population proportion and the sample proportion.

Attached geometry question. Please help. 100 points, will mark branliest.

-BARSIC- [3]

$\large{\rm{\underline{\underline{Answer:}}}}$

Since ∆AFB is similar to ∆ABC.

< F = < B (corresponding angle)
< G = < C (corresponding angle)
< A = common.

In ∆ABC,

⇛< A + < B + < C = 180°

⇛37° + 65° + < C = 180°

⇛102° + < C = 180°

⇛< C = 78°

We know that, < AGF / < G = < C

So, Measure of angle < AGF = 78° (ans)
