Trucks in a delivery fleet travel a mean of 120 miles per day with a standard deviation of 18 miles per day. The mileage per day

kvv77 [185]

The probability that a truck drives between 150 and 156 miles in a day is 0.0247. Using the standard normal distribution table, the required probability is calculated.

<h3>How to calculate the probability distribution?</h3>

The formula for calculating the probability distribution for a random variable X, Z-score is calculated. I.e.,

Z = (X - μ)/σ

Where X - random variable; μ - mean; σ - standard deviation;

Then the probability is calculated by P(Z < x), using the values from the distribution table.

<h3>Calculation:</h3>

The given data has the mean μ = 120 and the standard deviation σ = 18

Z- score for X =150:

Z = (150 - 120)/18

= 1.67

Z - score for X = 156:

Z = (156 - 120)/18

= 2

So, the probability distribution over these scores is

P(150 < X < 156) = P(1.67 < Z < 2)

⇒ P(Z < 2) - P(Z < 1.67)

From the standard distribution table,

P(Z < 2) = 0.97725 and P(Z < 1.67) = 0.95254

On substituting,

P(150 < X < 156) = 0.97725 - 0.95254 = 0.02471

Rounding off to four decimal places,

P(150 < X < 156) = 0.0247

Thus, the required probability is 0.0247.

Triangle sum and exterior angle theorem.

wlad13 [49]

Did two of them for you as reference for the rest.

Explanation for #1

The sum of all the angles in a triangle is 180. Simply add the given angles. Take 180 and subtract the sum of the given angles

180 - (58 + 47) = 75

Missing angle is 75

Explanation for #4

A straight angle is 180 degrees. Same thing as the first: add the given angles then take 180 and subtract it.

Then take 180 <em>again </em>and subtract the answer you got from the first step.

180 - (21 + 34) = 125

180 - 125 = 55

The missing angle is 55
