Answer:
15x = -75
x = -5
Step-by-step explanation:
Set the first part about the product of 15 and x equal to -75.
Then, divide both sides by -15 to get y = -5.
A) 14:10 = 7:15
b) 8:5
c) 5:10 = 1:2
d) 8 + 14 + 5 + 10 + 5 = 42
14:42 = 7:21 = 1:3
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
Answer:
The Answer is: Sharel is at -5.17 meters or 5.17 meters below sea level.
Step-by-step explanation:
Both Thor and Sharel are below sea level. Based on the fact they are below sea level, their elevation will be a negative number.
-10.12 - 4.95 = -5.17
