The probability that the value selected at random is greater than 30 will be found as follows:
z-score is given by:
z=(x-mu)/sig
z=(30-30)/2=0
thus
P(x>30)=1-P(X<30)=1-P(z<0)=1-0.5=0.5
Answer P(x>30)=0.5
Answer:
m<x=146
Step-by-step explanation:
its a supplementary angle, meaning both angles add up to 180.
So we subtract 34 from 180 which is 146.
180-34=146
If you are trying to figure out how many times greater something is:
For example, how many times is 12 greater than 6
Set unknown amount to variable (x)
6 * x = 12
Isolate x
x=12/6
x=2
You have the polygon MNOPQR which can be expressed as two rectangles pasted one next to each other.
To see the two rectangles in the picture, you can draw a line parallel to segment MR througn point N.
From the original picture you can state the dimensions of both rectangles.
Call S, the point where the line that you drew intercepts the segment RQ.
Then one rectangle is MNSR and the other rectangle is OPQS.
The measures of the sides of the rectangle MNSR are:
- the length of MN = length of SR = base
- the length of MR = the length of NS.= height
So its area is base * height, which you can all A1.
The measured of the rectangle OPQS are:
- segment OP = segment SQ = segment QR - segment SR = base
- segment PQ = segment OS = height
So its area is base * height, which you can call A2.
Then the area of the polygon MNOPQRS is A1 + A2. One of them is 9 u^2 and the other is what the answer is asking for, and that you have calculated above.
With this procedure you can tell the value needed.
To find the mean of something you are finding the average, so add all the times they were late to school. Then divide by the number of numbers you had to add. You will have your answer by doing that. What it means to interpret your answer is to explain it.
1. multiply the number of absences by the number of students.
2. Add the number of absences
3. divide by the number of students.
