Answer:

24

Step-by-step explanation:

The expression given is:

3a+b

We know that a is equal to 7 and b is equal to 3. Therefore, we can substitute 7 in for a, and 3 in for b.

3(7)+3

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Multiply 3 and 7 first

21+3

Add 21 and 3

Well, it is a binomial variable as long as you limit the amount of people you ask to a certain number for every trial.
Also, you MUST record the data either as they choose Frigidaire or they didn't choose Frigidaire. It MUST be these two choices, or it isn't binomial.

Suppose y varies jointly as x and z. Find y when x=-9 and z=23, if y=117 when x=-3 and z=-11. Round your answer to the nearest h
Andrew [12]

Answer:

The value of y given the values of x and z in the question is -734.85

Step-by-step explanation:

This is a joint variation question.

First, we are made to know that y varies jointly as x and z.

The equation for this can be written as;

y = k * x * z

Where k is the constant of proportionality.

Let’s calculate k first.

117 = k * (-3) * (-11)

33k = 117

K = 117/33 = 3.55

Now, we proceed to get what y is when x = -9 and z = 23

Let’s plug these values into the initial equation written.

y = k * x * z

We use the value of k calculated above;

y = 3.55 * (-9) * (23) = -734.85
