Answer:

Jessica has 48 different sets of classes to choose from.

Step-by-step explanation:

Given

The four categories are:

Economics: 5

Mathematics: 4

Education: 3

Sociology: 2

Suppose that sections for the 3 most popular classes in Economics are full.

Economics is left with (5-3) choices

Economics = 2 choices

Since there are equal chances of making selections, we multiply the number of options in each category to get the total set of classes Jessica can chose from.

Number of choices = 2 * 4 * 3 * 2

Number of choices = 48 choices

Hence, Jessica has 48 different sets of classes to choose from.

<span>Category         Number of Choices
Economics           5 - 3 = 2
Mathematics        4
Education            3
Sociology             2

Since out of 5 sections in Economics 3 are full, there are only 2 remaining sections available for Jessica to choose from.

I think this is a combination: 

n = 2 + 4 + 3 + 2 = 11
r = 1 + 1 + 1 + 1 = 4

nCr = n! / r!(n-r)! = 11! / 4!(11-4)! = 11! / 4! * 7! = 330

Jessica can have 330 different sets of classes to take.

One half of the sum of a number and 10
garri49 [273]

Let's assume the number be x.

So, sum of a number and 10 can be written as x+10.

Now the given statement is "One half of the sum of a number and 10 ".

So, one half of x+10 can be written as \frac{1}{2} (x+10)

1) h(x)=3x3<br>g(x)= - 4x+1<br>Find (h+g)(10)​
Aleksandr-060686 [28]

Answer:

(h+g)(10) = 2691

Step-by-step explanation:

h(x) = 3x^3\\g(x) = -4x+1

Adding both equations will make it:

(h+g)(x) = 3x^3-4x+1

Putting x = 10 will make it:

(h+g)(10) = 3(10)^3-4(10)+1

= 3(1000)-40+1

= 3000-39

= 2961

Over the three evenings,Karen received a total of 137 phone calls at the call center. The third evening, she received 4 times as
marin [14]

Answer:

1st: 22, 2nd: 27, 3rd: 88

Step-by-step explanation:

Make an equation

If she recieved x calls the 1st evening, then the 2nd evening she recieved x+5, and the 3rd evening she recieved 4x.

x+x+5+4x=137

Combine like terms

6x+5=137

Subtract 5 from both sides

6x=132

Divide by 6 on both sides

x=22

First:

22 calls

Second:

x+5

22+5

27 calls

Third:

4x

4*22

88 calls

Hope this helps!
