In this case, Ainsley is <em>adding </em>money to her savings, so the $75 deposit could be represented as the <em>positive </em>integer 75.
The opposite, of course, would be if Ainsley <em>withdrew </em>that money from her savings. In that case, we'd be subtracting money from the account, so we could use the <em>negative </em>integer -75 to represent that scenario.
Answer:
25, 70, 85
Step-by-step explanation:
x+2x+20+3x+10=6x+30
6x+30=180
6x=150
x=25
The angles are 25, 70, and 85

Answer:
Step-by-step explanation:
If repeated sample sizes of large sizes are taken at random, and proportion P is calculated for samples the sample mean will have a normal distribution irrespective of the original distribution.
In other words, the sample proportion will follow a normal distribution with mean = p-hat and std deviation =
This is a direct corrollary of central limit theorem for sample means.
Hence we have irrespective of sample size, sample proportion will have expected value same as p-hat.
So whether sample size is 500 or 100 the p hat will have the same distribution.
