Answer:

Multiplication...

Multiplication is just like adding a number to itself multiple times

For example: 3x3 is the same as 3+3+3

Division...

Division is basically splitting up a number between amother lower number, (it might be pretty difficult if you don’t know how to multiply though...)

Start by Rephrasing/re-ordering the equation (9/3 looks like 3*[?] =9)

1) Figure out what Factors equal 9 (by looking at a multiplication table or by adding up like described earlier)

2) You have your answer

(this took way too long to write and you’re probably an idiot if you’re actually in middle school...smh) I can write a different answer if you meant long division, or something else

12345 [234]

Answer:

a) e probability that a randomly selected baseball has a weight greater than 5.14 ounces

=P(X>5.14) =(b-x)/(b-a) =(5.155-5.14)/(5.155-5.085)=0.2143

probability that a randomly selected baseball has a circumference less than 9.03 inches

=P(X<9.03) =(x-a)/(b-a) =(9.03-9)/(9.1-9)=0.3

c) probability that a randomly selected baseball will have a weight between 5.11 and 5.13 ounces and a circumference between 9.04 and 9.06 inches

=((5.13-5.11)/(5.155-5.085))*((9.06-9.04)/(9.1-9.0))=0.0571
