Write and Solve Equations-Word Problems help

Step-by-step explanation:

So I want to say that art jumped 13 feet, and bill jumped 10

20/2=10,

10=bill's jump

10+3=13

13= arts jump

Arts=x+3

Bills=x

total=20

x+x+3=20

2x=20-3

2x-17

x=8 1/2 or  17/2

Arts=23/2 or 11 1/2

Bills=17/2 0r 8 1/2

Step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

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
