Solve for x X/6 = 10 A) X = 4 B) X = 10 C) X = 16 D) X = 60

Lina20 [59]

x/6 = 10

In a equation , you can use every math operation you know as long as you do the same thing on both sides.

Here we have x/6 = 10

But what I want is x .

Here X is split in 6. So I 'm going to multiplicate all by 6 to find the original amount of X

In bold operation that are often not written but that you must understand to do that kind of exercices.

So : x/6 = 10

(x/6) *6 = 10 *6

6x/6 = 60

x = 60

Ymorist [56]

Answer:

We want to verify if the true proportion of the alumni provide monetary contributions is higher than 0.15 (Alternative hypothesis), the system of hypothesis are.:

Null hypothesis: $p \leq 0.15$

Alternative hypothesis: $p > 0.15$

And the best answer for this case would be:

Ha: p > 0.15

Step-by-step explanation:

Information given

n=250 represent the random sample taken

X=40 represent the number of people on the alumni mailing list

$\hat p=\frac{40}{250}=0.16$ estimated proportion of people on the alumni mailing list

$p_o=0.15$ is the value to verify

z would represent the statistic

$p_v$ represent the p value

Hypothesis to test

We want to verify if the true proportion of the alumni provide monetary contributions is higher than 0.15 (Alternative hypothesis), the system of hypothesis are.:

Null hypothesis: $p \leq 0.15$

Alternative hypothesis: $p > 0.15$

And the best answer for this case would be:

Ha: p > 0.15
