Answer:
x = -10
Step-by-step explanation:
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:
x > 7
Step-by-step explanation:
Given
4x + 6 < 6x - 8 ( subtract 6x from both sides )
- 2x + 6 < - 8 ( subtract 6 from both sides )
- 2x < - 14
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.
x > 7
