Refer to the variable on the number of miles driven. the mean is 830.11 and the standard deviation is 42.19 miles. estimate the
Alex787 [66]
The proportion of buses traveling more than 900 miles would be 0.0485; multiply this by the total number of buses and you will have your answer.

We find the z-score associated with 900 miles:

z = (X - μ)/σ = (900-830.11)/42.19 = 1.66

Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of this, less than this, is 0.9515.  This means that the area under the curve to the right of this, greater than this, would be 1-0.9515 = 0.0485.

State the property that justifies the statement: If 4x + 9 = 15 and X=2y + 1,
GREYUIT [131]

Answer:

Substitution property of equality

Step-by-step explanation:

Given

4x + 9 = 15 and x = 2y + 1

Then

4(2y + 1) + 9 = 15

Required

State the property

From the list of options, (d) answers the question.

This is so because:

Substitution property of equality states that

If a = b then b = a

In other words, both can replace one another.

So if x = 2y + 1, then 2y + 1 can be substituted for x in 4x + 9 = 15

So:

4x + 9 = 15  becomes

4(2y + 1) + 9 = 15

<em>Hence, it is substitution property of equality</em>
