What is the value of y ?

Answer & Step-by-step explanation:

For this problem we can just set up an equation and equal it to 180.

(2y) + (y + 10) + 50 = 180

Combine like terms.

3y + 60 = 180

Subtract 60 from 180.

3y = 120

Divide 120 by 3.

y = 40

So, the value of y is 40°

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

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.
