A construction crew has repaired 1.37 miles of a highway. The total length of the highway to be repaired is 7.9. How many miles
JulijaS [17]

Answer:

Part A: m+1.37=7.9

Part B: 6.53 miles are left to be repaired.

Step-by-step explanation:

Given,

Length of repaired part = 1.37 miles

Total length to be repaired = 7.9 miles

Miles left to be repaired = m

Part A:

Create an equation to show the relationship between the number of miles repaired and the number of miles left to be repaired, m.

Miles left to be repaired + Length of repaired part = Total length to be repaired

m+1.37=7.9

Part B

How many miles are left to be repaired?

Subtracting 1.37 from both sides

6.53 miles are left to be repaired.

Keywords: length, subtraction

Step-by-step explanation:

I just started the problem, but I'm a bit lost on what to do now.

According to Greg himself (probably a master at pies) says perfect cherry pies have a ratio of 240 cherries to 3 pies. First, we need to divide 240 cherries by 3 pies to find out how many cherries are in one pie.

240 / 3 = 80

Then multiply by 9 to get your answer.

9 * 80 = 720

Find the line parallel to the line y=3x+5 which passes through the point (1,4). a. y=-1/3x+1 b. y=-3x+1 c. y=1/3x+1 d. y=3x+1
Vladimir [108]

Answer:

D

Step-by-step explanation:

So we want to find the equation of the line parallel to y=3x+5 and goes through the point (1,4).

First, since the new line is parallel, its slope must be equivalent. Therefore, the slope of our new line <em>must</em> also be 3.

Now, we can figure out the rest of the equation using the point-slope form:

y-y_1=m(x-x_1)

Substitute 3 for m. Let's let (1,4) be x₁ and y₁. Thus:

y-4=3(x-1)

Distribute the right:

y-4=3x-3

Add 4 to both sides:

y=3x+1

And we're done!

The correct answer is D.

The diameters of ball bearings are distributed normally. The mean diameter is 123 millimeters and the standard deviation is 4 mi
Mrac [35]

Answer:

0.0668

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 123, \sigma = 4

Find the probability that the diameter of a selected bearing is greater than 129 millimeters.

This is 1 subtracted by the pvalue of Z when X = 129. So

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

Z = \frac{129 - 123}{4}

Z = 1.5

Z = 1.5 has a pvalue of 0.9332

1 - 0.9332 = 0.0668

0.0668 = 6.68% probability that the diameter of a selected bearing is greater than 129 millimeters.
