Answer:

20% of 30 < 30% of 40

Step-by-step explanation:

Find 20% of 30

20/100 = x/30

Cross multiply

20 × 30 = 100 × x

600 = 100x

Divide both sides by 100

6 = x

Find 30% of 40

30/100 = x/40

Cross multiply

30 × 40 = 100 × x

1200 = 100x

Divide both sides by 100

12 = x

Compare the two answers:

6 and 12

6 < 12

Using the arrangements formula, it is found that there are 24 ways to arrange the people as such one works each quarter.

The number of possible arrangements of n elements is given by the factorial of n, that is:

[tex]A_n = n![/tex]

In this problem, 4 people will be arranged, hence:

[tex]A_4 = 4! = 24[/tex]

Hence, they can be arranged in 24 ways.

Answer:

0.15 = 15% probability that a randomly selected passenger has a waiting time greater than 4.25 minutes.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:

[tex]P(X > x) = \frac{b - x}{b - a}[/tex]

Uniformly distributed between 0 and 5 minutes.

This means that [tex]a = 0, b = 5[/tex]

Find the probability that a randomly selected passenger has a waiting time greater than 4.25 minutes.

[tex]P(X > 4.25) = \frac{5 - 4.25}{5 - 0} = 0.15[/tex]

0.15 = 15% probability that a randomly selected passenger has a waiting time greater than 4.25 minutes.

Answer:

15.49

Step-by-step explanation:

The pythagorean theorem

4^2 + B^2 = 16^2

16 + B^2 = 256

16 + 240 = 265

Sqrt240 = 15.49

Answer:

[tex]x = 15.49[/tex]

Step-by-step explanation:

To solve this problem is necessary to use the pythagorean theorem:

According to this diagram, the length of the ladder would be the hypotenuse and the distance between the base and the wall would be one of the legs of the triangle, to find the other leg, use the pythagorean theorem:

[tex]x = \sqrt{ {16}^{2} - {4}^{2} } \\ x = \sqrt{240} \\ x = 15.49[/tex]

The ladder hits the wall at 15:49 feet.

Answer:

(18x + 6)m

(Anyone can correct me if I'm wrong)

Step-by-step explanation:

Perimeter = 2l + 2w

Perimeter = 2(7x - 3) + 2(2(x + 3))

Perimeter = 14x - 6 + 4(x+3)

Perimeter = 14x -6 +4x +12

Perimeter = (18x + 6)m

Answer:

9

Step-by-step explanation:

7x - 3 = 60

7x = 60 + 3

7x = 63

x = 63 ÷ 7

x = 9

first, find the circumference of the circle

2πr = 2π × 5

= 31.42 ft

then multiply the circumference with the angle given which is 50° divided by 360°.

31.42 × 50 ÷ 360 = 4.36 ft

answer = 4.36 ft

Answer:

Since the pvalue of 0.0985 > 0.05, we cannot infer that the satisfaction rate is less than the claim with a level of significance of 5%

Step-by-step explanation:

The null hypothesis is:

[tex]H_{0} = 0.9[/tex]

Because tate Farm claims that policyholders have a customer satisfaction rate of greater than 90%.

The alternate hypotesis is:

[tex]H_{1} < 0.9[/tex]

Because of the question: Can we infer that the satisfaction rate is less than the claim with a level of significance of 5%.

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

State Farm claims that policyholders have a customer satisfaction rate of greater than 90%.

This means that [tex]\mu = 0.9, \sigma = \sqrt{0.9*0.1}[/tex]

To check the accuracy of this claim, a random sample of 60 State Farm policyholders was asked to rate whether they were satisfied with the quality of customer service.

This means that [tex]n = 60[/tex]

Fifteen percent of these policyholders said they were not satisfied with the quality of service.

So 100 - 15 = 85% were satisfied, which means that [tex]p = 0.85[/tex]

Test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.85 - 0.9}{\frac{\sqrt{0.9*0.1}}{\sqrt{60}}}[/tex]

[tex]z = -1.29[/tex]

[tex]z = -1.29[/tex] has a pvalue of 0.0985.

Since the pvalue of 0.0985 > 0.05, we cannot infer that the satisfaction rate is less than the claim with a level of significance of 5%

Answer:

Option.B

Step-by-step explanation:

Its because if you add these two angles you get a supplementary angle or 180°

Using this we can form an equation to find the value of x.

(And is this question from Khan Academy?)

Answer:

The first error is in line 1.

Step-by-step explanation:

The equation that represents the statement is:

[tex]4-\frac{x}{3}=11[/tex]

it is four (4) less than a number (x) divided by three (3) is 11.

Therefore, we need to start from this equation, so the first error is in line 1.

I hope it helps you!
