IgorC [24]

Answer:

\dfrac{560}{t} pages per hour.

given that t is the amount of time gives her class to read.

Step-by-step explanation:

It isn't stated that exactly how many minutes the teacher gave Alex to read.

So to go further with this solution, we'll say that the teacher gave t minutes reading time to each student. (so you can just replace t with the actual  number in your answer)

Alex read 9\frac{1}{3}[tex] pages in [tex]t minutes.

by dividing the pages with the time, we'll find the rate of pages at which Alex reads per minute.

9\frac{1}{3} \div t

we can simplify the mixed fraction

\dfrac{28}{3} \times \dfrac{1}{t}

\dfrac{28}{3t} \frac{\text{pages}}{\text{minute}}  (Alex's speed)

To find out how many page Alex will read in an hour we can simply convert the minutes to hour by multiplying by 60 minutes.

\dfrac{28}{3t} \frac{\text{pages}}{\text{minute}} \times \frac{\text{60 minute}}{\text{hour}}

we can see that the minutes cancel out. and 60 multiplies with 28.

\dfrac{1680}{3t} \frac{\text{pages}}{\text{hour}}

\dfrac{560}{t} \frac{\text{pages}}{\text{hour}}

this shows that Alex read \dfrac{560}{t} pages per hour.

<h2>Answer:</h2><h2>If a respondent from the survey is selected at random, compute the probability that the respondent has a Master's degree. = \frac{67}{850}</h2>

Step-by-step explanation:

The number of people in the survey = 850

No of people with no High School Diploma = 52

No of people with High School Diploma =  234

No of people with with associate's Degree or Two Years of College  = 274

No of people with Bachelor's Degree = 187

No of people with Master's Degree = 67
