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

Answer:

For x<1, answer would be A.

Step-by-step explanation:

Since the less than sign doesn't have a line under it "making it less than or equal to" the dot on the graph is not shaded, and if you simply read the inequality, x is less than 1, so it goes in the direction less than 1.

Answer:

the answer above this one is wrong

respectfully

Step-by-step explanation:

The answer is " < "

because angle F is greater than angle C, which means line ED is longer than AB

Answer:

h = √72 in.

Step-by-step explanation:

Height of the cone using pythagorean theorem, a² + b² = c², where:

a = h

b = ½(6) = 3 in.

c = 9 in.

Plug in the values

h² + 3² = 9²

h² + 9 = 81

h² + 9 - 9 = 81 - 9

h² = 72

h = √72

Answer:

9 = x (assuming 15 is the hypotenuse)

Step-by-step explanation:

15^2 = 12^2 + x^2

225 = 144 + x^2

subtract 144 from both sides

81 = x^2

square root both sides

9 = x

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:

8 to the nearest whole is 10

8 is over halfway so its 10.

Step-by-step explanation:

8 5/9 rounded to nearest whole is 9

5/9 id about 1/2 and 1/2 is about a whole so its 9

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.

Answer:

=7:2

Step-by-step explanation:

63:18

divide both sides by 3

=21.6

divide by 3 again

=7:2

Answer:

The equation of line a is y=(1/2)x−1, and it passes through point (6,2).

       line b is: y = -2x + c and we use point (-6,2) to find b.

      2 = -2(-6) + c

     14 = c

The equation for line b is: y = -2x + 14

The y-intercept (which is the point where x=0) is the point (0,14.)        So, y=14

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.
