Answer:

Mean = 42

Step-by-step explanation:

Given

Represent Fred with F; Norman with N and Dave with D.

Total = 128

D = 44

Required

Determine the arithmetic mean of F and N

First, we have that:

F + N + D = 128

Substitute 44 for D

F + N + 44 = 128

Subtract 44 from both sides

F + N + 44 - 44 = 128 - 44

F + N  = 84

Arithmetic mean of F and N is calculated as follows:

Mean = \frac{F + N}{2}

Mean = \frac{84}{2}

Mean = 42

Does the function model exponential growth or decay? f(t)=1/4⋅4^t
yarga [219]

Answer:

This is an exponential decay

Because the base of the exponent is 1/4.4 which is less than 1

Step-by-step explanation:

What is exponential growth?

when the base of our exponential is bigger than 1, which means those numbers get bigger.

What is exponential decay?

when the base of our exponential is in between 1 and 0 and those numbers get smaller.

2x + y = 2<br><br> x – 2y = -4<br><br> what is x and y?
sergiy2304 [10]

Answer:

x = 0

y = 2

Step-by-step explanation:

2x + y = 2 (Multiply by 2)

x – 2y = -4

4x + 2y = 4

x – 2y = -4

5x = 0

x = 0

2x + y = 2

2(0) + y = 2

0 + y = 2

y = 2

What is -5/8 times 2/3 equal in fraction form
anastassius [24]

Answer: -5/12

Step-by-step explanation: Before multiplying two fractions together by multiplying across their numerators and multiplying across their denominators, you should always try to cross-cancel as your first step.

So in this problem, the 2 and 8 cross-cancel to 1 and 4.

Also, watch out for your signs. In this problem we have a negative times a positive so we know that our answer will be negative.

Now we can multiply across the numerators and across the denominators.

So we have 5 · 1 which is 5 and 4 · 3 which is 12.

So our answer is -5/12.

Be very careful with your signs!
