<h3>Solution:</h3>
By multiplying it by 100, we can get the answer.
<h3>Given Ratio:</h3>Answer: Mean of the sample proportion = 74.4
Standard deviation of the samnple proportion is 5.32.
Step-by-step explanation:
Given : A random sample of 120 is taken from a population of 10000.
Let n = 120
Also, from previous survey, it is believed that 62% of the population has an Instagram account.
i.e, population proportion : p = 0.62
Now , the mean of the sample proportin would be :
i.e. Mean of the sample proportion = 74.4
The standard deviation of the samnple proportion would be :
Thus , the standard deviation of the samnple proportion is 5.32.
Answer:
- a) AB = 10 units
- b) Midpoint is (2, 6)
===================
<h3 /><h3>Given</h3>- Points A( - 1, 10) and B(5, 2)
- a) The length of AB
- b) The midpoint of AB
a) Use the distance formula:
Substitute the coordinates and calculate:
The distance is AB = 10 units
b) Use midpoint formula and find x and y- coordinates of this point:
and
Substitute coordinates and find the midpoint:
and
The midpoint is (2, 6)
