Hi There! :)
<span>Which numbers should be multiplied to obtain 175^2 − 124^2?
</span><span>51 and 299</span>
x*(1.035) + (4,200-x)*(1.045) = 4,374.00
1.035x + 4,389.00 -1.045x = 4,374.00
15.00 = .01x
x = 1,500 so x (1,500) invested at 3.5% and
(4,200 - 1,500) (or 2,700) invested at 4.5%
Answer:
mean: 107.86
median: 100
range: 140
mode: 100
Step-by-step explanation:
Answer:
$200
Step-by-step explanation:
2.5 % commission on sales
he sold 8000
his commission will be sales * 2.5%
commission = 8000 * .025
= 200
Answer:
Step-by-step explanation:
I really hope you know how to use your calculator to find regression equations, because in this forum it is impossible to teach you how to do that. I ran the data through my calculator and got the exponential equation as
which means at 4 hours, we started with 1963 bacteria and it is growing at a rate of 114% each hour. Since we started out with an x value of 0, and that value represents the number of bacteria after 4 hours, then time 0 is 4 hours, which means that time 12 is 16 hours. We replace the x in the equation with a 12 and do the math:
which gives us, in the end,
y = 9460
