A large school district found that 88 of 100 randomly selected students at East High School had internet access
at home. A separate random sample from West High showed 79 of 100 students had internet access at home.
Administrators used those results to make a 90% confidence interval to estimate the difference between the
proportion of students at each school who have internet access at home (PE - Pw). The resulting interval was
approximately 0.09 0.086. They want to use this interval to test H, : PE = Pw versus H : PE + Pw at
the a = 0.10 significance level. Assume that all conditions for inference have been met.
Based on the interval, what do we know about the corresponding P-value and conclusion at the a=0.10
level of significance?
Answers
It can be deduced that the p-value is less than the level of significance.
What is a level of significance?It should be noted that the level of significance simply means the measure of the strength of the evidence that's is present in a sample before the null hypothesis is rejected.
From the complete question, the confidence interval is a given as (0.004, 0.176). In this case, the p-value is less than the level of significance and they should conclude that there's a difference between the proportions.

Write 0.614¯¯¯ as a fraction in simplest form.
Answers
Answer:
307/500
Step-by-step explanation:
307 is a prime number.
The way to find this out is to take 0.614 and multiply it by 1,000 because then it will be a natural number. 0.614*1,000=614.
now you take 614/1,000 because that's what you multiplied it by and simplify it.
614/2 and 1,000/2=307/500 and this cannot be simplified any more than this because 307 is a prime number.

Kevin works two part-time jobs and wants to earn a total of at least $504 per week. He earns an
average of $12 per hour delivering food and $14 per hour working retail
A.) Write the inequality representing the scenario
B.) Graph the inequality
Answers
Kevin earning at least $504 implies that he wants to earn $504 or more
The inequality representing the scenario is [tex]12x + 14y \ge 504[/tex]
How to interpret the scenario?The given parameters are:
Earnings = At least $504
Food delivering = $12 per hour
Retail = $14 per hour
Represent the number of hours delivering food with x, and the retail work with y.
So, the earning is:
Earning = 12x + 14y
The earning is at least $504.
So, we have:
[tex]12x + 14y \ge 504[/tex]

star?
The perimeter is about
cm.
The area is about
cm2
Answers
Answer:
The answer is 16 cm
Step-by-step explanation:
If the area was 16cm^2 before, then each side was 4 cm long since each side of a square is equal, and the area for a square is the length of the sides squared. The square root of 16 is 4, so that is why the sides were 4 cm. When you make each side 1 cm shorter, they're now all 3 cm. 3^2 is 9, so the new area is 9 square centimeters.

Step-by-step explanation:
24: 18
Divide each side by 6
24/6 : 18/6
4 : 3
Answer: 4:3
Step-by-step explanation: so firstly we will see the common factors of 24 and 18.
the factors of 24 is 1, 2, 3, 4, 6, 8, 12, 24
the factors of 18 is 1, 2, 3, 6, 9, 18
we can see that the common factors are 1, 2, 3, 6
so the largest common factor is 6
so you divide 24 by 6 and that will give you 4
then you divide 18 by 6 and it will give you 3
so 24:18 simplify =4:3

Answer:
4.0 cm
Step-by-step explanation:
The volume of the frustum is the volume of the full cone (with height y + 7) minus the volume of the upper smaller cone (with height y).
Formula:
volume of cone = (1/3)πr²h
For the full cone:
r = 8 cm
h = y + 7
volume of cone [in cm³] = (1/3)π(8²)(y + 7)
volume of cone [in cm³] = (1/3)π(64)(y + 7)
volume of cone [in cm³] = (64π/3)(y + 7)
For the upper cone:
volume of cone = (1/3)πr²h
volume of cone = (1/3)π(4²)y
volume of cone = (16π/3)y
For the frustum:
volume = volume of full cone - volume of upper cone
volume = (64π/3)(y + 7) - (16π/3)y
volume = 64πy/3 + 448π/3 - 16πy/3
volume = 48πy/3 + 448π/3
Now we solve for y:
48πy/3 + 448π/3 = 670.2
50.265y + 469.144 = 670.2
50.265y = 201.056
y = 4.0

y - 4 = (5 - 4)/(-1 - 2) × (x - 2)
y - 4 = 1/(-3) × (x - 2)
-3y + 12 = x - 2
