C.) (5,0)
Step-by-step explanation:
You see where the lines cross together. That will be the answer.
A:science b: social studies, math, other, english, and science
Let x be the required waranty period, then
P(X < x) = P(z < (x - 12)/(8/12)) = 1 - 0.067 = 0.933
P(z < 12(x - 12)/8) = P(z < 1.498)
12(x - 12)/8 = 1.498
x - 12 = 8(1.498) / 12 = 0.9987
x = 12 - 0.9987 = 11
Therefore, they should waranty for 11 years so that no more than 6.7% fail within that time.
cost of production = %13
Let the price be p, then
revenue less price of failed iron = p - 0.067(13) = p - 0.871
Profit = p - 0.871 - 13 = 5
p - 13.871 = 5
p = 5 + 13.871 = 18.871
Therefore, the should charge $18.87 per waffle iron.
Answer:
B.25
Explanation:
The figures are similar. This means that corresponding sides have the same ratio.
This helps us set up a proportion.
We know that ML corresponds with DC, which gives us the ratio
8/40
EF will correspond with NH; this gives us the ratio
5/x
The proportion is then
8/40 = 5/x
Cross multiplying, we have
8(x) = 40(5)
8x = 200
Divide both sides by 8:
8x/8 = 200/8
x = 25
