Round this number to the nearest 10.
32
a. 20
b. 40
c. 30

B. 20

Step-by-step explanation:

32 rounded to the nearest 10 would be 20 because 2 is a less than 5, so it will go down. Making 3 turn to 2 and 2 into 0 = 20

30 , because since the digit beside it is lower than 5 you go down.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
