Answer:

w = 11

Step-by-step explanation:

5=\frac{w}{2.2}

2.2 × 5=\frac{w}{2.2} × 2.2

11 = w

w = 11

What is the total amount paid for a $60 meal with a 15% tip and 8% tax?
Taya2010 [7]

Answer:

I believe it would be 73.8 or if they are rounding up 74.

Step-by-step explanation:

15% of 60 is *9* and 8% of 60 is *4.8*

9+4.8=13.8

13.8+60=73.8.

Find the equation of the graphed line.
Kamila [148]

Answer:

y = -x + 4

Step-by-step explanation:

Mathematically, the equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

from the plot, the y intercept is 4

So we have;

y = mx + 4

To get the value of m, we substitute the coordinates of any point and solve for m

we select the point; (4,0)

so;

0 = m(4) + 4

4m = 0-4

4m = -4

m = -1

so the equation of the line is;

y = -x + 4

Trucks in a delivery fleet travel a mean of 100 miles per day with a standard deviation of 38 miles per day. The mileage per day
WINSTONCH [101]

Answer:

0.7931 = 79.31% probability that a truck drives between 43 and 141 miles in a day.

Step-by-step explanation:

Problems of normally distributed samples are 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 = 100, \sigma = 38

Find the probability that a truck drives between 43 and 141 miles in a day.

This is the pvalue of Z when X = 141 subtracted by the pvalue of Z when X = 43. So

X = 141

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

Z = \frac{141 - 100}{38}

Z = 1.08

Z = 1.08 has a pvalue of 0.8599

X = 43

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

Z = \frac{43 - 100}{38}

Z = -1.5

Z = -1.5 has a pvalue of 0.0668

0.8599 - 0.0668 = 0.7931

0.7931 = 79.31% probability that a truck drives between 43 and 141 miles in a day.
