Your local provider has twin internet plans.
Their casual plan is $1.50 for every 10 gigabytes used. Their heavy plan charges a flat rate of $20, and then $0.50 for every 10 gigabytes of usage.
Write equations in the form y=mx+b where y is the cost and c is the number of gigabytes used

casual = y=1.5(10)+0 and heavy = y= .50(10)+20

Step-by-step explanation:

casual;

1.50 = your slope

10 is your x because it can change

and it starts at 0 because there's no flat rate making your y-intercept 0.

This makes your equation y=1.5(10)+0

heavy;

.50 = slope

10 is also your x here

this one starts at 20 on the graph because it is the flat rate and thus, the y-intercept.

This makes this equation y=.50(10)+20

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
