Answer: 93 units should be ordered.
Step-by-step explanation:
Since we have given that
Standard deviation = 4
Average = 30 units
Number of weeks in order interval = 3
Desired service level = 97.5%
Number of units on hand = n = 43
So, the expected value would be
![E[x]=30\times (3+1)+1.96\times 4\sqrt{3+1}-43\\\\E[x]=30\times 4+1.96\times 4\times 2-43\\\\E[x]=120+15.68-43\\\\E[x]=92.68\approx 93](https://tex.z-dn.net/?f=E%5Bx%5D%3D30%5Ctimes%20%283%2B1%29%2B1.96%5Ctimes%204%5Csqrt%7B3%2B1%7D-43%5C%5C%5C%5CE%5Bx%5D%3D30%5Ctimes%204%2B1.96%5Ctimes%204%5Ctimes%202-43%5C%5C%5C%5CE%5Bx%5D%3D120%2B15.68-43%5C%5C%5C%5CE%5Bx%5D%3D92.68%5Capprox%2093)
Hence, 93 units should be ordered.
It is equal to 2(x)^3 because pemdas, exponnets come before multiplication so it would be x^3 then multiply whatever that is by 2
2x^3 is answer (4th choice)
Answer:
r = -46/3
Step-by-step explanation:
-3(r+2)=40
Distribute
-3r - 6 = 40
Add 6 to each side
-3r-6+6 = 40+6
-3r = 46
Divide by -3
r = 46/-3
r = -46/3

Answer:</h2>
The statement which best describes the effect of replacing the function f(x) with g(x) is:
The graph shifts 7 units up.
<h2>
Step-by-step explanation:</h2>
The function f(x) is given by :

The function f(x) is a linear function with positive slope.
and the function g(x) is given by:

The function g(x) is a linear function with same positive slope.
Also, we know that any transformation of the type:
f(x) → f(x)+k
is a translation transformation such that it if k>0 then it is a shift k units upwards and if k<0 then it is a shift k units downward.
Here we have:
g(x)=2x+5-2+2
i.e.
g(x)=2x-2+7
i.e.
g(x)=f(x)+7
Hence, the function g(x) is a translation of the function f(x) 7 units upward.
Answer:
0.95 miles per minute
19 miles in 20 minutes
Step-by-step explanation:
To find out how many miles traveled in a minute, we will divide 57 by 60, because there are 60 minutes in an hour, and there were 57 miles traveled in a hour. This gives you the rate of miles per minute (0.95), and to get the answer for 20 minutes, just multiply 0.95 by 20 (19 miles).
