Model with mathematics. Hamid has read 60 pages of the book
he will be using for a book report. If he reads 45 pages per hour, how
many hours will it take him to read at least 375 pages of the book?
Define a variable, and then write and solve an inequality to represent
this situation. Graph the solution on a number line.

Answers

Answer 1

Answer:

Hamid will take 8 hours and 20 minutes to read 375 pages of the book.

Step-by-step explanation:

Given that Hamid has read 60 pages of the book he will be using for a book report, if he reads 45 pages per hour, to determine how many hours will it take him to read at least 375 pages of the book the following calculation must be done:

375/45 = X

8.3333 = X

0.333 x 60 = 20

Thus, Hamid will take 8 hours and 20 minutes to read 375 pages of the book.

Devonte is 7 years older than Hanna. In 7 years the sum of their ages will be 83. How old is Devonte now?

Answers

Answer:

Hannah = 34 and 1/2

Devonte = 41 and 1/2

Step-by-step explanation:

Hanna = x

Devonte = x+7

x+x+7=83-7

2x+7=76

2x=76-7

2x=69

x=34.5

Hannah = x = 34.5

Devonte = x+7 = 41.5

The green point is the lowest point and from drawing the curve, we see that the next highest point coordinate is (4.114, 6).

The period is the x-coordinate distance between the two highest points. Thus;

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the initial value be represented as A = 13.60 at time t = 0

Now , when the value is changed to 17.00

The absolute change = 17.00 - 13.60 = 3.40

The relative change = 3.40 / 13.60 = 0.25 = 25 %

Now , the percentage = 25 %

And , when the value is changed to 21.25

The absolute change = 21.25 - 17.00 = 4.25

The relative change = 4.25 / 17.00 = 0.25 = 25 %

And , when the value is changed to 26.56

The absolute change = 26.56 - 21.25 = 5.31

The relative change = 5.31 / 21.25 = 0.25 = 25 %

Now , the percentage = 25 %

And , when the value is changed to 33.20

The absolute change = 33.20 - 26.56 = 6.64

The relative change = 6.64 / 26.56 = 0.25 = 25 %

And , when the value is changed to 41.50

The absolute change = 41.50 - 33.20 = 4.25

The relative change = 8.3 / 33.20 = 0.25 = 25 %

Now , the percentage = 25 %

Hence , the relative change is given by the equation A = 25 %

Answers

Answer:

c. We are 92% confident that the mean height of the entire business is in this interval.

f. The 85% confidence interval is a subset of the 92% confidence interval.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

Margin of error:

The larger the confidence interval, the larger the margin of error. That means that for example, an 85% confidence interval is a subset of the 92% confidence interval.

In this question:

92% confidence interval -> We are 92% sure that the population mean is in this interval.

The 85% confidence interval is a subset of the 92% confidence interval.

So options c and f.
