Answer:

See below.

Step-by-step explanation:

Just like 18, continue with 19-21. Solve for x by rewriting each equation in log form.

$e^x = 4.9\\\\x = ln 4.9\\\\x = 1.59$

When rewriting the form, the base of the exponent becomes the base of the log.

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.

Question:

MArishka [77]

Answer:

73°

Step-by-step explanation:

Given, Angle A = 17° and Angle B = 90°

As it is a triangle, sum of all the angles are 180°

so,

⇒ Angle A + Angle B + Angle C = 180°

⇒ 17° + 90° + Angle C = 180°

⇒ Angle C = 73°

Mariko has an 80: 1 scale drawing of the floor plan of her house. On the floor plan

Ivan

Answer:

16,771.56 square feet.

Step-by-step explanation:

In order to get to the result we will need to use the scale and the numbers that are provided of the dimensions of the room.

The dimensions of the room on the floor plan are 17.8 inches by 21.2 inches. We first need to multiply these numbers with the scale:

17.8 x 80 = 1,424

21.2 x 80 = 1,696

Now that we got the real measures we need to multiply these two values in order to get to a result as in how many square inches is the room:

1,424 x 1696 = 2,425,104

Now we need to convert the square inches into square feet to get to the final result:

1 ft² = 144 in²

2,425,104 / 144 = 16,771.56

So we have a result of 16,771.56 square feet.
