Which is the best prediction of the number of chores completed if she earns $5?

The graph is missing, so i have attached it.

Best prediction of number of chores completed if she earns $5 = 2 chores

Step-by-step explanation:

From the graph attached, it is a graph of money earned (y-axis) vs chores completed (x - axis).

The equation of the graph is given as; y = 2.09x + 0.93

Where x is the number of chores completed and y is the corresponding amount earned.

Thus, if she earns $5, we will plug in 5 for y in the equation of the graph.

So,

5 = 2.09x + 0.93

2.09x = 5 - 0.93

2.09x = 4.07

x = 4.07/2.09

x ≈ 2

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
