Answer:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Step-by-step explanation:
Σx = 77, Σy = 587, Σx2 = 1593, Σy2 = 70,533, and Σxy = 10040.
Where:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
The question seems incomplete, but if you are trying to figure out how much each dress costs, The answer would be $30.
To find the answer all you need to do is;
1. Subtract the price of the jeans ($40) From the total price.
160-40=120
2. Now we know the total price of the Dresses, and we also know she bought 4 of them, this means we can divide the total price ($120) of dresses, by the number (4) of dresses bought.
120/4 = 30.
So therefor, each dress costs $30 Dollars.

17.5
This is because if you do the math: (7/40)*100 you get 17.5!
So divide 7 by 40 and then multiply it by 100!
7/40=0.175
0.175*100=17.5
Answer:
its 15.75 please give me brainliest hope I helped
