It's just dividing out the factoring to their simplest form.
The bold numbers are the answers that go in the circles.

1. 16 < 8 and 2
8 < 2 and 4
4 < 2 and 2

2. 42 < 14 and 3
14 < 7 and 2

3. 40 < 2 and 20
20 < 10 and 2
10 < 2 and 5

4. I'm not able to see the rest of the factoring tree

When Colton commutes to work the amount of time it takes him to arrive is normally distributed with a mean of 41 minutes and a s

larisa86 [58]

Answer:

The Probability that commute will be between 33 and 35 minutes to the nearest tenth = 0.0189 ≅1.89%

Step-by-step explanation:

Step(i):-

Given mean of the Population(μ) = 41 minutes

Given standard deviation of the Population (σ) = 3 minutes

let 'X' be the random variable of Normal distribution

Let X = 33

$Z = \frac{x -mean}{S.D} =\frac{33-41}{3} = -2.66$

let X = 35

$Z = \frac{x -mean}{S.D} =\frac{35-41}{3} = -2$

Step(ii):-

The Probability that commute will be between 33 and 35 minutes to the nearest tenth

P(33≤ X≤35) = P(-2.66 ≤X≤-2)

= P( X≤-2) - P(X≤-2.66)

= 0.5 - A(-2) - (0.5 - A(-2.66)

= 0.5 -0.4772 - (0.5 -0.4961) (From normal table)

= 0.5 -0.4772 - 0.5 +0.4961

= 0.4961 - 0.4772

= 0.0189

The Probability that commute will be between 33 and 35 minutes to the nearest tenth = 0.0189 ≅1.89%
