The diagonals intersect perpendicularly, two consecutive angled are supplementary, and that opposite angles are equal
Bag of potatoes are usually 10 pounds
SOLUTION
The mean is 4min
standard deviation is 1min
the z score is

where

then we have

The probability the call lasted less than 3 min will be
Therefore, the probability that (z < -1 ) is
[tex]\begin{gathered} Pr(z<-1)=Pr(0
Hence, the percentage of the calls that lasted less than 3 min is 16%
Answer:
If the question states that they are not being replaced, then the answer is 1/8
If the question states that they are being replaced, then the answer is 1/9
Step-by-step explanation:
3/9 x 2/8 = 1/8
3/9 x 2/9 = 1/9
Answer:
2x−3=x
Move all terms containing x
to the left side of the equation.
Subtract x
from both sides of the equation.
2x−3−x=0
Subtract x
from 2x
x−3=0
Add 3
to both sides of the equation.
x=3
