Probability helps us to know the chances of an event occurring. The probability that a randomly selected student is a junior is 0.35.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}

The probability that a randomly selected student is a junior will be,

P(Junior) = [(Number of Juniors)\(Number of total students)]

P(Junior) = 35/100 = 0.35

Hence, The probability that a randomly selected student is a junior is 0.35.

Xanthia can read 100 pages per hour and Molly can read 50 pages per hour. If they each read the same book, and the book has 225
Talja [164]

Answer:

135 minutes

Step-by-step explanation:

Let

y -----> the number of pages to finish reading the book

x ----> the number of hours

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the unit rate or slope of the linear equation

b is the y-intercept or initial value

In this problem we have

<em>Xanthia</em>

m=100\ pages/hour

b=225\ pages

y=-100x+225 ----> the slope is negative because is a decreasing function

For y=0

substitute and solve for x

0=-100x+225

100x=225

x=2.25\ hours ---> Xanthia's time to finish reading the book

<em>Molly</em>

m=50\ pages/hour

b=225\ pages

y=-50x+225 ----> the slope is negative because is a decreasing function

For y=0

0=-50x+225

50x=225

x=4.5\ hours --- Molly's time to finish reading the book

To find out how many more minutes than Xanthia would it take for Molly to finish reading the book, subtract Xanthia's time from Molly's time

4.5\ h-2.25\ h=2.25\ h

Convert to minutes

Multiply by 60

2.25\ h=2.25(60)=135\ minutes

Which expression is equivalent?
gregori [183]
The correct option is: Option (C) log_3c - log_{3}9

Explanation:
It is the property of log that if it contains the fraction, it can be expressed as the difference of the log of numerator and the log of denominator.

The general form is:
log( \frac{x}{y} ) = log(x) - log(y)

Hence the correct answer is log_3c - log_{3}9.
