Counting backwards from 5, what number is 4?

The number 4 is the first term of the sequence

Step-by-step explanation:

we know that

Counting backwards is when the numbers are count in reverse sequence

Is also know as 1 less

In this problem the sequence of counting backwards from 5 is equal to

4,3,2,1,0

therefore

The number 4 is the first term of the sequence

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

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
