Answer:
1. X=1/2y+5/2 or y=2x-5, 2 picture
2. X=-3/2y+6 or y=-2/3x+4, 2 picture
3. X=-1/2y+-11/2 or y=-2x-11, 1 picture
4. X=-0.5y+1.5 or y=-2x+3
5. Y=4/3x-9
6. Y=1/4x-2
Step-by-step explanation: I can give you 5 picture, I can’t give you the another step-by-step, hope this help
We want to compare averages. From the histogram we have we don't know the exact mean, but if we just assume the average in each bin is the midpoint of the bin we can make an estimate.
Supplier A has
mean = ( 22(64) + 27(66) + 26(68) + 15(70) + 10(72) )/(22+27+26+15+10)
mean = 6728/100 = 67.28 grams
Supplier B has mean 66.5
Answer: Choose Supplier A
(work shown above)
Answer:
k=-2
Step-by-step explanation:
Using substitution to find what you're missing, (in this case k) is when you plug each letter into the other equation:
-4k+3=3k+17
So now solve for k:
subtract 3 from both sides...
-4k=3k+14
subtract 3k from both sides to combine with -4k...
-7k=14
divide -7 from both sides...
k=-2
Hey! I believe the answer is A. Have a nice/great day! :-)
