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 = proportion of respondents who would be bothered about given a room on the thirteenth floor

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

Alternate Hypothesis, $H_A$ : p > 85%

Here, null hypothesis states that 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, alternate hypothesis states that 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 :)

In ∆ABC, which ratio equals cos C? A. B. C. D.

Bond [772]

SOH CAH TOA

CAH

Cosine = Adjacent / Hypotenuse

∆ABC, where lets say B is the right angle.

cos C = adjacent/hypotenuse = BC/AC
