Answer:

Dorinda worked at Job A for 11 hours

Step-by-step explanation:

Step one

This is a word that leads to simultaneous.

Let us begin by modeling the system of equation from the problem

Let x and y be the number of hours worked in both jobs A and B respectively

Step two

x+y=30---------1

7.5x+8y=234.50----2

Solving the equations simultaneously we have

1. Multiplying equation 1 by 8 and equation 2 by 1 and subtracting from equation 2 to find y

8x+8y=240---------1

- 7.5x+8y=234.50----2

=0.5x=5.5

x=5.5/0.5

x= 11hrs

Substituting x=11 in equation 1 we can find y

11+y=30

y= 30-11

y= 19hrs

Susan rolled a die 1,086 times. Which of the following would be a good estimate of the number of times she rolled the number 3 o
adell [148]

Hello!

This is a problem about probability.

What we would first do is find the theoretical probability that Susan would roll the number 3 on a die.

Assuming that this is a fair six sided die, there is only one face with the number 3, and there are 6 sides, meaning that the probability that Susan rolls a 3 would be \frac{1}{6}.

Now, Susan is rolling a die 1,086, meaning that we can divide this number by 6 to find the theoretical number of times that Susan would roll the number 3 on this die.

You should get 181 times, which would be a good estimate of how many times she could roll the number 3.

Hope this helps!
