Answer:
A
Step-by-step explanation:
2x² - 12x - 14
2(x² - 6x - 7)
2(x² - 7x + x - 7)
2(x - 7)(x + 1)
Answer:
11=DE
Step-by-step explanation:
3x-28+3x-30+x=33
7x-58=33
7x=91
x=13
3(13)-28
39-28=11
Answer:
The selling price be $79.56 .
Step-by-step explanation:
Let us assume that the cost price be x.
As given
If the markup is $8.95 and the overhead is $4.31 .
Selling price = Cost price + Markup price + Overhead price
= x + 8.95 + 4.31
= x + 13.26
Profit = Selling price - Cost price
= x + 13.26 - x
= $ 13.26
Formula

Putting the values in the above formula



x = $ 66.3
Thus cost price be $66.3 .
Thus
Selling price = $66.3 + $13.26
= $ 79.56
Therefore the selling price be $79.56 .

Answer:
p(on schedule) ≈ 0.7755
Step-by-step explanation:
A suitable probability calculator can show you this answer.
_____
The z-values corresponding to the build time limits are ...
z = (37.5 -45)/6.75 ≈ -1.1111
z = (54 -45)/6.75 ≈ 1.3333
You can look these up in a suitable CDF table and find the difference between the values you find. That will be about ...
0.90879 -0.13326 = 0.77553
The probability assembly will stay on schedule is about 78%.
