Answer:
The standard deviation of X is 0.7
Step-by-step explanation:
We are given the following distribution:
x: 0 1 2 3
P(x): 0.3 0.5 0.2 0.4
We have to find the standard deviation of X.
Formula:

Thus, the standard deviation of X is 0.7
You have to divide 86 by 18 .which she can make about 5 necklaces
Answer:
y+6
Step-by-step explanation:
If we increase x then we need to do it with y by the same number.
We can not increase with different numbers.
Our rule of translation now is (x+6,y+6)
(x,y)=(x+6,y+6)
We have A(-6,2) then A'(0,8)
B(-5,5) then B'(1,11)
