Negative 1 and four-fifths
Negative StartFraction 5 over 9 EndFraction
StartFraction 5 over 9 EndFraction
1 and four-fifths
c.StartFraction 5 over 9 EndFraction
D. is not the answer and four-fifths i think the best answer

Use the following scenario for the next 4 questions: Based on the results of an annual customer satisfaction survey of State Farm policyholders, State Farm claims that policyholders have a customer satisfaction rate of greater than 90%. 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. Fifteen percent of these policyholders said they were not satisfied with the quality of service. Can we infer that the satisfaction rate is less than the claim with a level of significance of 5%
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%

20% of 30 ___30% of 40
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
Plz help if correct ill give brailiest also the first answer was x<1
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.

Use the Pythagorean theorem to find the length of the leg in the triangle shown below 12 15
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

number = 26
Round 8
to the nearest whole number.
Round 8 5/9 to the nearest whole number
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
C. Find the equation that is parallel to y = 12x-2 and crosses the point (6,2)
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
Step-by-step explanation:
hope this helps :)

Step-by-step explanation:
Which line shows the first error in the solution?
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!
Find the height of this cone using the Pythagorean Theorem. 9 in. h = [?] in. 6 in. a C Pythagorean Theorem: a2 + b2 = c2 b
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
