It’s been found that 85% of American adults suffer from triskaidekaphobia (fear of the number 13). Researchers think this is too
uysha [10]

Answer:

Null Hypothesis, H_0 : p \leq 85%

Alternate Hypothesis, H_A : p > 85%

Step-by-step explanation:

We are given that it's been found that 85% of American adults suffer from triskaidekaphobia (fear of the number 13).

A USA Today/Gallup poll asked 1,006 randomly selected people 18 years old and older in telephone interviews "Suppose you checked into a hotel and were given a room on the thirteenth floor. Would this bother you or not?" 87% of the survey respondents answered they would be bothered.

Let p = <u><em>proportion of respondents who would be bothered about given a room on the thirteenth floor</em></u>

SO, Null Hypothesis, H_0 : p \leq 85%

Alternate Hypothesis, H_A : p > 85%

Here, <u>null hypothesis states that</u> the proportion of respondents who would be bothered about given a room on the thirteenth floor is less than or equal to 85%.

On the other hand, <u>alternate hypothesis states that</u> the proportion of respondents who would be bothered about given a room on the thirteenth floor is more than 85%.

Hence, this would be the correct null and alternative hypothesis.

Devide (a2+ 7a+ 12)÷ (a+3)​
arlik [135]

Answer:

(a - 3) • (a - 4)

Step-by-step explanation:

The first term is,  a2  its coefficient is  1 .

The middle term is,  -7a  its coefficient is  -7 .

The last term, "the constant", is  +12

Multiply the coefficient of the first term by the constant   1 • 12 = 12

Find two factors of  12  whose sum equals the coefficient of the middle term, which is   -7 .

     -12    +    -1    =    -13

     -6    +    -2    =    -8

     -4    +    -3    =    -7    That's it

Rewrite the polynomial splitting the middle term using the two factors, -4  and  -3

                    a2 - 4a - 3a - 12

Add up the first 2 terms, pulling out like factors :

                   a • (a-4)

             Add up the last 2 terms, pulling out common factors :

                   3 • (a-4)

Add up the four terms

                   (a-3)  •  (a-4)

Really hope this helps :)
