Similar means that the student's desk and the teacher's desk is proportional.
Simplify:
Solve for x.
50*3=5*x
x=30. in.
Answer:
I'm pretty sure it's the 3rd option
First distribute the outside negative 2 to each number and multiply u should get -2a * -4b* 6/4 and there u go it's simplified but teachers are very EXTRA in middle school and want an explanation so u should say sumthin like "there were no like terms meaning you can't simplify any further"
Answer:
Given :The monthly demand for a product is normally distributed with mean = 700 and standard deviation = 200.
To Find :
1. What is probability demand will exceed 900 units in a month?
2. What is probability demand will be less than 392 units in a month?
Solution:
We are supposed to find probability demand will exceed 900 units in a month.
Formula :
We are supposed to find P(Z>900)
Substitute x = 900
Refer the z table.
P(Z<900)=0.8413
P(Z>900)=1-P{(Z<900)=1-0.8413=0.1587
So, the probability that demand will exceed 900 units in a month is 0.1587.
Now we are supposed to find probability demand will be less than 392 units in a month
We are supposed to find P(Z<392)
Substitute x = 392
refer the z table
P(Z<900)=0.0618
So, probability that demand will be less than 392 units in a month is 0.0618.
The surface area of the smaller prism is 9/25 the area of the larger one. So the linear dimensions are in the ratio of 3:5 .
