Answer:
Now we can find the p value using the alternative hypothesis with this probability:
Since the p value is large enough, we have evidence to conclude that the true proportion for this case is NOT significanctly higher than 0.75 since we FAIL to reject the null hypothesis at any significance level lower than 30%
Step-by-step explanation:
Information provided
n=100 represent the random sample selected
estimated proportion of students that are satisfied
is the value that we want to test
z would represent the statistic
represent the p value
System of hypothesis
We want to verify if more than 75 percent of his customers are very satisfied with the service they receive, then the system of hypothesis is.:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
Now we can find the p value using the alternative hypothesis with this probability:
Since the p value is large enough we have evidence to conclude that the true proportion for this case is NOT significanctly higher than 0.75 since we FAIL to reject the null hypothesis at any significance level lower than 30%
Answer:
x axis
Step-by-step explanation:
it will be higher than the first point but not move left or right so by visualising it would be reflected by the x-axis
Answer: 
Step-by-step explanation:
We have the following expression:
![(\sqrt[3]{x^{2}} \sqrt[6]{x^{4}})^{-3}](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Bx%5E%7B2%7D%7D%20%5Csqrt%5B6%5D%7Bx%5E%7B4%7D%7D%29%5E%7B-3%7D)
Which can also be written as:
Since we have exponents with the same base 
inside the parenthesis, we can sum both exponents:
Now, we have to multiply the exponent out of the parenthesis with the inner exponent and have the following result:
Answer:
7. MN = 12
8. m<XYZ = 90°
9. m<YXM = 49°
10. m<XWZ = 131°
Step-by-step explanation:
This drawing is messed up.
The perspective is off because <NMW looks to be an obtuse angle because it appears to be greater than a square angle or 90°.
The median should be accurate in perspective even though WZ appears to be greater than MN or XY which is greater than WZ but appears to be smaller than WZ.
Answer:
$15
Step-by-step explanation:
Let Sam's Money =s
Let Janet's Money =j
of Sam's money equals 
of Janet's money.
Let n be the number of dollars held by Sam and Jane respectively
Therefore: 
s=3n
j=2n
s+j=3n+2n=5n
Together, they have more than $10
Therefore:
5n>10
n>2
The least sum they could have is at n=3
At n=3
s+j=5n=5X3=$15
The least number of dollars they could have combined is $15.
