Answer:
x(1÷4) y(-2)
Step-by-step explanation:
4x= -1-y
4x- 3y= 7
-1-y-3y=7
y= -2
4x-3 x (-2)=7
x=1÷4

Step-by-step explanation:
Answer:
I think 10.5 would be the unit price and 10lbs of potatoes and 2lbs of tomatoes would cost less
Step-by-step explanation:
since tomatoes cost 2 times more I decided to act as he only bought potatoes and in that case he would have bought 22lbs of potatoes so I divided 16.50 by 22 and got .75 then I multiplied it by 10 and got 7.5 as well as multiplied .75 by two to get the price of the tomatoes then I added 7.5+3 to get 10.5
The sampling distribution is illustrated below.
<h3>How to illustrate the sampling?</h3>
Based on the information given, the population is illustrated as 1, 4, 7. The sample without replacement will be:
<u>Sample Mean</u>
1 and 4. 2.5
1 and 7. 4
4 and 7. 5.5
The population mean will be:
= (1 + 4 + 7)/3
= 4
The sample mean is an unbiased estimator of the population mean.
The sampling with replacement illustrates that the mean will be:
= 36/9 = 4
Also, when n = 3, the number of samples will be:
= 3³ = 27
