Stella is renting a car for a business trip. The agency charges a flat rate of \$60 plus \$0.50 per mile every mile she drives over 40 miles. Stella's company will pay up to \$270, excluding the cost of gasoline , for the use of the rental car. What is the number of miles Stella can drive the rental car without spending more then\$270

270 =60 + 0.50(x-40)

270 =60 + 0.50x -20

210 =0.50x -20

230=0.50x

x=230/0.50 = 460 miles

check:

460-40 = 420

420*0.50=210 +60=270

she can drive 460 miles total

Find x when y=18, if y=5 when x=4

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

We need to find x value, when y is eighteen.

if y=5 when x=4

It means those two are in proportional relationship.

Let us form an equation

x/18=4/5

Apply cross multiplication

5x=4×18

5x=72

Divide both sides by 5

x=14.4

Hence the value of x is 14.4 when y is eighteen.

The average time an individual reads online national news reports is 49 minutes. Assume the standard deviation is 16 minutes and that the times are normally distributed. What is the probability someone will spend no more than 30 minutes reading online national news reports?

11.70% probability someone will spend no more than 30 minutes reading online national news reports.

Step-by-step explanation:

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

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

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:

What is the probability someone will spend no more than 30 minutes reading online national news reports?

This is at most 30 minutes, so 30 or less minutes. This is the pvalue of Z when X = 30.

So

has a pvalue of 0.1170.

So there is a 11.70% probability someone will spend no more than 30 minutes reading online national news reports.
