Answer:

y = 3/2 x - 11

Step-by-step explanation:

y = -2/3 x + 5; slope = -2/3

Perpendicular line, slope is reciprocal and opposite so slope of the line that is perpendicular to the y = -2/3 x + 5 is 3/2

Passes through (8,1)

Equation

y -1 = 3/2 (x - 8)

y - 1 = 3/2 x - 12

y = 3/2 x - 11

Answer:

A.) JH = 1 in

B.) GH = 3/4 in

C.) m∠F = 62°

D.) m∠J = 118°

Step-by-step explanation:

In a parallelogram, opposite angles are congruent, adjacent angles are supplementary, and opposite sides are congruent.

A.) JH = FG = 1 in

B.) GH = FJ = 3/4 in

C.) m∠F = m∠H = 62°

D.) m∠J = m∠G = 180° -62° = 118°

Answer:

0.726 is the probability that the project will be completed in 33 days or less.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 30 days

Variance = 25 days

Standard Deviation,

$\sigma = \sqrt{\text{Variance}} = \sqrt{25} = 5$

We assume that the distribution of path length is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(completed in 33 days or less)

$P( x \leq 33) = P( z \leq \displaystyle\frac{33 - 30}{5}) = P(z \leq 0.6)$

Calculation the value from standard normal z table, we have,

$P(x \leq 33) = 0.726 = 72.6\%$

0.726 is the probability that the project will be completed in 33 days or less.
