A crowd-sourced review platform believes that more and more customers are writing reviews online. The crowd-sourced review platform would like to test the claim that the percent of customers who leave a review online is greater than 72%. They decide to complete a hypothesis test at a 1% significance level. They sample 30 customers, and determine the sample percent to be 90%. The following is the data from this study: Sample size =30 customers Sample proportion =0.90 Identify the null and alternative hypothesis for this study by filling in the blanks with the correct symbol (=,≠,<, or > to represent the correct hypothesis.)
Answers
Answer:
H0 : P = 0.72
H1 : P > 0.72
Step-by-step explanation:
Claim is to test that percentage of customers who leave a review is greater than 72%
From the information given :
P0 = 72/100 = 0.72
The null hypothesis, H0 : P = 0.72
Alternative hypothesis claims the proportion is greater than 0.72 and from the sampling result obtained, phat = 0.90
Hence,
Alternative hypothesis, H1 : P > 0.72

A pitcher of iced tea holds 128 ounces. A large orange cooler holds 1792 ounces of iced tea. How many pitchers of iced tea will it take to fill the large orange cooler? * NO LINKS PLZZ!!!
A.12
B.24
C.14
D.18
Answers
The big orange cooler will hold 14 pitchers of iced tea. The response is C.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Since a pitcher of iced tea holds 128 ounces, we can find the number of pitchers required to fill the large orange cooler by dividing the total volume of the cooler by the volume of one pitcher:
1792 / 128 = 14
Therefore, it will take 14 pitchers of iced tea to fill the large orange cooler. The answer is C.

Why is c speed of light in albert einseins eqation e=mc squared

The speed of light (c) is considered a fundamental constant of nature. In the famous relativity equation, E = mc², the speed of light (c) serves as a constant of proportionality, linking the formerly disparate concepts of mass (m) and energy (E).
Solve this system of equations using the substitution method y=5x+4 x+12=y
Answers
Answer:
(2,14)
Step-by-step explanation:
Since y=5x+4, you can plug that into the other y in the other equation which would give you x+12=5x+4
Now subtract 12 from both sides
x=5x-8
Subtract 5x from both sides
-4x=-8
Now you divide them both by -4 which gives you x=2
Now plug x in to any of the equations
y=5(2)+4
y=10+4
y=14
Your final answer is (2,14)
What is the domain? Is it (-4,3)
Answers
Yes I think you are correct. The domain appears to be the set of x values such that -4 < x < 3 meaning that x is between -4 and 3, excluding each endpoint. In interval notation, that translates to (-4, 3). This of course assumes that we have two vertical asymptotes bookending the left and right sides of the curve, and these vertical asymptotes are at x = -4 and x = 3. If the curve extends beyond these boundaries, then the domain would instead be the set of all real numbers.

For what value of z would the following system of
equations be true for all real integers?
3x-2y = 14
-12x+8y = 8z
Answers
9514 1404 393
Answer:
z = -7
Step-by-step explanation:
The equations will be true for all real integers when they are a dependent set. That will be the case when the second equation is a multiple of the first.
Already, we observe that the ratios of x- and y-coefficients are -4:
-12/3 = -4
8/-2 = -4
The equations will be dependent when the constants have that same ratio:
8z/14 = -4 . . . . desired ratio
8z = -56 . . . . . multiply by 14
z = -7 . . . . makes the equations true for all real numbers
_____
Comment on the question
The system of equations can be made inconsistent (no solutions) or consistent & dependent (infinite solutions) by the choice of z.
However, integer solutions are limited to pairs of the form (2n+2, 3n-4) for integer values of n. The values of x and y are not "all real integers".
Consequently, we have interpreted the question to be asking for the value of z that will make the system of equations have an infinite number of solutions, including both rational and irrational, real and complex values of x and y. They cannot be made to be true for "all real integers" by any choice of z.
Answer:
z = -7 is the answer.Step-by-step explanation:

Miguel is 4 years older than 2/3 of Harper's age. The sum of their ages is 34. His harper 16?
Answers
Answer:
Harper's age = 18
Miguel age = 16
Step-by-step explanation:
Given:
Miguel age = [2/3][Harper's age] + 4
Sum of their age = 34
Computation:
Assume;
Harper's age = a
So,
Miguel age = [2/3][a] + 4
Sum of their age = 34
So,
Miguel age + Harper's age = 34
[2/3][a] + 4 + a = 34
[2a / 3] + a = 34 - 4
[2a + 3a] / 3 = 30
5a / 3 = 30
5a = 90
a = 18
So,
Harper's age = 18
Miguel age = [2/3][a] + 4
Miguel age = 16
