**Answer:**

** the probability is 0.0750**

**Step-by-step explanation:**

The computation of the probability is shown below;

The mean of x is

= 1.5 ÷ √79

= 0.1688

Now the probability is

= P(Z < -0.3 ÷ 0.1688) + P(\bar{x} > 0.3 ÷ 0.1688)

= P(Z < -1.78) + P(Z > 1.78)

= P(Z < -1.78) + 1 - P(Z < 1.78

= 0.0375 + 1 - 0.9625

= **0.0750**

hence,** the probability is 0.0750**

Lola purchases music from two online services. Company A charges Lola a $10

subscription fee plus 89 cents for each song. Company B charges no subscription fee but

$1.19 per song. What is the minimum number of songs Lola would have to purchase for

Company A to be the cheaper option?

9514 1404 393

**Answer:**

8. (c) 34

9. 38 women

**Step-by-step explanation:**

8. The price for s songs is ...

A = 10 +0.89s

B = 1.19s

We want A < B, so ...

10 +0.89s < 1.19s

10 < 0.30s

33.33... < s

**Lola would have to purchase 34 songs for Company A to be the cheaper option**.

9. Let m represent the number of men. Then the number of women (w) is ...

w = 4m+2

The total of men and women is 47, so we have ...

m + w = 47

m + (4m +2) = 47

5m = 45 . . . . . . . . . subtract 2

m = 9 . . . . . . . . . . . .divide by 5

4m +2 = 4(9) +2 = 38 . . . . find the number of women

**The PTA has 38 women in it**.

An environmentalist wants to find out the fraction of oil tankers that have spills each month. Step 1 of 2: Suppose a sample of 211 tankers is drawn. Of these ships, 146 did not have spills. Using the data, estimate the proportion of oil tankers that had spills. Enter your answer as a fraction or a decimal number rounded to three decimal places.

**Answer:**

The estimate of the proportion of oil tankers that had spills is 65/211 = 0.308.

**Step-by-step explanation:**

**Proportion of oil tankers that had spills.**

Number of tankers with spills divided by the total number of tankers.

**In this question:**

211 tankers

146 did not have spills, so 211 - 146 = 65 had

**Proportion:**

[tex]p = \frac{65}{211} = 0.308[/tex]

The estimate of the proportion of oil tankers that had spills is 65/211 = 0.308.

A company that produces white bread is concerned about the distribution of the amount of sodium in its bread. The company takes a simple random sample of 100 slices of bread and computes the sample mean to be 103 milligrams of sodium per slice. Construct a 99% confidence interval for the unknown mean sodium level assuming that the population standard deviation is 10 milligrams.

**Answer:**

The 99% confidence interval for the unknown mean sodium level is between 100.42 milligrams of sodium per slice and 105.58 milligrams of sodium per slice.

**Step-by-step explanation:**

We have that to **find **our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

**Now**, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.58.

**Now, find the margin of error M as such**

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.58\frac{10}{\sqrt{10}} = 2.58[/tex]

The **lower end** of the interval is the sample mean subtracted by M. So it is 103 - 2.58 = 100.42 milligrams of sodium per slice.

The **upper end** of the interval is the sample mean added to M. So it is 103 + 2.58 = 105.58 milligrams of sodium per slice.

The 99% confidence interval for the unknown mean sodium level is between 100.42 milligrams of sodium per slice and 105.58 milligrams of sodium per slice.

Please give me the correct answer.Only answer if you're very good at math.Please use the Pythagorean Theorem formula which is a^2 + b ^2 = c^2.

**Answer:**

8.7 in

**Step-by-step explanation:**

a = 7.3

b = 4.8

c^2 = 7.3^2 + 4.8^2 = 76.33

c = sqrt(76.33) which is around 8.7

A backpack is on sale for $51.00. This is 75% of the original price. What was the original price?

Original price= $204.

100%-75%= 25% or 0.25.

51 = 0.25 * n (original price)

Divide 0.25 on both sides

51/0.25 = 204

N=204

That is indeed a very expensive backpack.

100%-75%= 25% or 0.25.

51 = 0.25 * n (original price)

Divide 0.25 on both sides

51/0.25 = 204

N=204

That is indeed a very expensive backpack.

In ADEF, the measure of ZF=90°, the measure of ZD=69°, and FD = 64 feet. Find

the length of DE to the nearest tenth of a foot.

9514 1404 393

**Answer:**

178.6 ft

**Step-by-step explanation:**

The definitions of the trig functions tell you ...

Cos = Adjacent/Hypotenuse

cos(69°) = FD/DE

DE = FD/cos(69°) ≈ (64 ft)/0.3584

** DE ≈ 178.6 ft**

Monthly budget: $1200

If he spends 25% on food each month, you can interpret it as a fourth of his budget because 25/100 is equal to 1/4.
