If 66 feet is a typo for 6 feet, then the answer is 330 feet long. Multiply 6•7.34= 44.04 round to 44. 2424/7.34= 330.245 round to 330. This is the height of the building.

If there is no typo 66/3= 22•2= 44

2424/3= 808•2= 1,616 feet tall.

The set of life spans of an appliance is normally distributed with a mean Mu = 48 months and a standard deviation Sigma = 8 mont
natita [175]

To solve the problem we must know about Z-Score.

<h3>What is Z-score?</h3>

A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,

Z = \dfrac{X- \mu}{\sigma}

Where Z is the Z-score,

X is the data point,

μ is the mean and σ is the standard variable.

The life span of an appliance that has a z-score of –3 is 24 months.

Given to us

  • Mean, μ = 48 months,
  • standard deviation, σ = 8 months,
  • Z-Score = -3

<h3> What is the life span of an appliance?</h3>

The life span of the appliance can be calculated using the Z-score formula,

Z = \dfrac{X- \mu}{\sigma}

Substitute the values,

-3 = \dfrac{X- 48}{8}\\\\-3 \times 8 = X - 48\\\\-24+48=X\\\\X = 24\ months

Hence, the life span of an appliance that has a z-score of –3 is 24 months.

Use the given information to write the equation of the line in slope-intercept form: y = mx + b
worty [1.4K]

Answer:

y  =2x + 3

Step-by-step explanation:

Given

(-2,-1) and (3,9).

Required

Determine the line equation

First, we calculate slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

Where

(x_1,y_1) = (-2,-1)

(x_2,y_2) = (3,9)

So, we have:

m = \frac{9 - (-1)}{3- (-2)}

m = \frac{9+1}{3+2}

m = \frac{10}{5}

m = 2

The equation is then calculated using:

y - y_1 = m(x - x_1)

y - (-1) =2(x - (-2))

y - (-1) =2(x +2)

y +1 =2(x +2)

Open bracket

y +1 =2x + 4

Subtract 1 from both sides

y +1-1 =2x + 4-1

y  =2x + 3

Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. So the y-intercept of y = 3x + 2 is 2
