In a class of 29 students, 19 are female and 14 have an A in the class. There are 8students who are male and do not have an A in
1 answer:
SOLUTION
The total number of females =
if 14 have an A in the class, the number of students without A is:
8 male students do not have an A, therefore the number of female students without an A is:
The probability that a student does not have an A given that the student is female can be calculated thus:

The true statement for f(x)=b^x is the function is always decreasing function.
We have given,
f(x)=b^x where 0<b<1
<h3>What is the domain?</h3>Domain is all possible values of x for which any function is defined
We can select any values of x for which function
It will be defined for all real x
So, the domain is
The range is all possible values of y for which x is defined
we are given that b is positive
The value of the function will always be positive
So, the range is
y>0
The x-intercept:
Set f(x)=0 and then we can solve for x
f(x)=b^x=0
x is undefined
The x-intercept does not exist
Increasing or decreasing:
Since, 0<b<1
The b is a positive value less than 1
As we increase the value of, will keep decreasing
This is decreasing function

36 students have traveled outside of the United States, when there are total 120 sixth graders.
<u><em>Explanation</em></u>
The number of students traveled outside of the United States is 9 when there is total 30 sixth graders. So, the ratio of the student traveled to the total students will be
Now there are total of 120 sixth graders in the school and lets assume the number of students traveled outside the United states is . That means the ratio...
So, 36 students have traveled outside of the United States.
