You need to post a graphic. I tried drawing my own, but I do not know where point "P" is nor where point "R" is.
Answer:
1/16
Step-by-step explanation:
4^-2 is the same as 1/4^2
and then calculate 4^2 to get 16, making it 1/16.
To awnser this , you first need to discover how much is 9% of 15000 that you invested.
To discover that you can just divide by 100 and multiply by 9
15000 ÷ 100 = 150
150 × 9 = 1350
So each year he earns $1350 but he has $1000 annual payments , so he only profit $350 a year.
Now to discover how long it will take to achieve $1.000.000 back you can just take the the $15.000 he needs to have 1.000.000 and divide by how much he profit each year
15000÷350= 42.85
which means it will take approximately 42 years and 10 months to achieve $1.000.000
<h2>
Answer with explanation:</h2>
Let
be the average weight of chocolate chips in each bag.
As per given , we have

Since
is left-tailed , so we perform a left-tailed test.
Also, the population standard deviation is known
.
So we use z-test.
Test statistic : 
Substitute given value ,

Significance level = 0.05
Decision rule : Reject
when p-value < 0.05.
By z-table , P- value for left-tailed test = P(z<-1.96)= 1- P(z<1.96)
[∵ P(Z<-z)=1-P(Z<z)]
= 1- 0.9750
=0.025
Since , P-value(0.025) < 0.05 , so we reject the null hypothesis.
We support the claim that the machine is underfilling the bags at 0.05 significance level .
