Answer:
x⁴-196x³+9204x²+32200x+40000
Step-by-step explanation:
(x+2)(x+2)×(x-100)(x-100)=
(x²+4x+4)×(x²-200x+10000)=
(x⁴-200x³+10000x²+4x³-800x²+40000x+4x²-800x+40000)
=x⁴-196x³+9204x²+32200x+40000
Answer:
Slope: 4
Y-intercept: -5
Equation: y=4x-5
Step-by-step explanation:
Slope formula:
So let's use the ordered pairs (1, -1) and (2,3) from the table (it doesnt matter which ones you choose) and plug the numbers in to the formula:
Which is equal to:
Which is equal to 4. So the slope is 4.
To find the y-intercept, substitute the slope and an ordered pair into the slope-intercept equation, y=mx+b. So let's use (1,-1).
-1=4(1)+b
= -1=4+b
= -1-4=4-4+b
= -5=b
So the y-intercept is -5.
Then for the equation, you just plug in the slope and the y-intercept into y=mx+b, which would be:
y=4x-5
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

Answer:
Ricky: 1202
Pedro: 1480
Step-by-step explanation:
Ricky: x
Pedro: x+278
2x+278=2682
2x=2404
x=1202
Remember Ricky is x so he has 1202 hits
1202+278=1480
