Answer:
9/2 is the slope of the graphed line.
The second statement is true.
Step-by-step explanation:
Answer:
A sample size of 1031 is required.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is of:
37% of freshmen do not visit their counselors regularly.
This means that
98% confidence level
So , z is the value of Z that has a pvalue of , so .
You would like to be 98% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required?
A sample size of n is required.
n is found when M = 0.035. So
Rounding up:
A sample size of 1031 is required.
Answer:
Step-by-step explanation:
x = (-315* 2)/360 = - 630
- 21 /12 = -7
Answer:
1. x = 180 - 25 - 93 = 62°
2. x = 180 - 100 - 70 = 10°
3. x = 180 - 38 - 23 = 119°
4. x = 90 - 43 = 47°
5. x = 180 - 57 - 49 = 74°
6. x = 180 - 46 - 82 = 52°
Answer:
-0.83 <√4 <2.63 <√8
Step-by-step explanation:
We need to place the numbers √4, 2.63, √8, and-.83 in order from least to greatest.
We know that,
√4 = 2, √8 = 2.82
A number line starts from negative no then 0 and finally positive numbers.
The smallest no is negative no i.e. -0.83 and the greatest no is √8 i.e. 2.82
The sequence from least to greatest is :
-0.83 <√4 <2.63 <√8
