What numbers are 1.4 units from −3.2 on a number line? pick one from both sets of answers a.-4.6 b. -4.4c.-4.2d. -4.0a.-2.2b.-2.0c.-1.8d.-1.6?

we are given

numbers are 1.4 units from −3.2 on a number line

so, we will add and subtract 1.4 to -3.2

Addition:

-3.2+1.4=-1.8

Subtraction:

-3.2-1.4=-4.6

so,

option-a and option-cAnswer

A and c

Step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
