Answer:

A. 0.62%

B. 28 months

Step-by-step explanation:

A. Calculation for what percentage of total production will the company expect to replace

Let x represents the distribution of life times

Let mean be 34 months

Let standard deviation be 4 months.

Based on the information the full refund on any defective watch for 2 years will represent 24 months (2 years *12 months).

First step

P(X<24)

= p(x-mean/ standard deviation< 24-34/4)

= p(z< -10/4)

=P(z<-2.5)

Second step is to Use the excel function to find NORMSDIST(z) of P(z<-2.5)

NORMSDIST(z)=0.62%

Therefore the percentage of total production will the company expect to replace will be 0.62%

B. Calculation for how much the guarantee period should be

First step

P(X<x)=0.06

P(x-Mean/Standard deviation < x-34/4) = 0.06

Second Step is to Use excel function

P(z<x-34/4) = (Normsinv(0.06)

x-34/4 = -1.555

Now let calculate how much the guarantee period should be

x = -6.22+34 months

x = 27.78

x = 28 months (Approximately)

Therefore the guarantee period should be 28 months

Given STU and DEF, what is m
jek_recluse [69]

Answer:

While slavery was the major issue separating the North and South, it was not slavery itself that sparked the conflict. The South wanted to secede from the Union, and the North refused. While President Abraham Lincoln personally opposed slavery, he recognized that it was legal under the U.S. Constitution at the time. He also recognized that few in the North were ready to go to war to free the slaves. For Lincoln and the northern majority, preservation of the Union was the foremost goal.

How to factor out tue coefficient of the variable
PIT_PIT [208]
Lets say you have a question such as 7x+1=15.

First you have to start with the addition or subtraction because of PEMDAS. In order to get rid of the +1, you have to subtract 1 from it and do the same thing to the number on the other side of the equal sign.
7x+1-1=15-1
Which leaves you with
7x=14
What you want to do is get the variable by itself so, since the variable is basically multiplying itself by the coefficient, you want to divide the 7x by 7 to get rid of the coefficient. Make sure to do the same for both sides of the equation!
7x/7=14/7

x=2

Thats the answer.
Hopefully you can figure this out on your own problem.

1) The length of the shadow the tree cast and the shadow Bill cast needs to be added together which makes 34 ft
2) After setting up Bill's Height and Shadow over each other 6ft/9ft.. Set that equal to another proportion...
3) The next proportion is x (the height of the tree) and the length (along the bottom) X/34
4 Solveeee :) 6/9 multiplied by 34 is 22.6- 22 ⅔ft as a fraction
andddd you're done that's the answer
