a) define the variables
The variables are x and y ; x can represent the number of times Aleah goes swimming ; while y can represents the number of times Aleah goes skating.

b) are there any restrictions on the variables?
The total sum of both activities must be equal or less than $80 a month

c) write a linear inequality to represent this situation
Swimming costs $5 each time and skating costs $4 each time. No more than $80 a month.

5x + 4y < 80

You can graph linear inequality using these coordinates.

natalie guessed on the last four true or false questions on her math quiz. what is the probability that she got all four quiz qu

Verizon [17]

Each question is either true or false, so the sample space is 2, true and false, two states only.

what's the probability she got one correct, well, the favorable outcomes is 1, possible outcomes is 2, so 1/2.

what's the probability that she got all four correct, we simply multiply the probability of each,

$\bf \cfrac{1}{2}\cdot \cfrac{1}{2}\cdot \cfrac{1}{2}\cdot \cfrac{1}{2}\implies \cfrac{1}{16}\implies 0.0625\qquad or\qquad 6.25\%$
