Answer:
The mean is 6.2.
Step-by-step explanation:
The "mean" is the same thing as the "average". Essentially, the question is asking for the average of the numbers.
So:
Add up all of the terms. [6 + 11 + 5 + 2 + 7] = 31
You find the average by dividing the sum of the terms (31) by the number of terms (5).
31/5 = 6.2
The mean is 6.2.
I hope this helped! :)
Step-by-step explanation:
you should only make one equation:
75 + 45x = 30 + 55x
subtract the 30 frim both sides, then subtract 45x from both sides. you are left with:
45 = 10x
Divide by 10 and get:
4.5 = x
After 4.5 hours, the cost is equal for either worker.
Answer:
y = 0.2x + 37
Step-by-step explanation:
A) Find an equation in the form y = mx + b, where x is the number of monthly minutes used and y is the total monthly of the Ringular plan.
(x, y) = (minutes, cost)
(110, 59)
(600, 157)
slope = m = dy/dx
dy/dx = change in y/change in x
m = dy/dx
m = (157 - 59)/(600-110)
m = 98/490
m = 0.2
a) the linear equation:
y - 59 = 0.2(x - 110)
y - 59 = 0.2x - 22
y = 0.2x - 22 + 59
y = 0.2x + 37
Answer:
The answer is 45600 as 621 is less than 650 and should be rounded down.
-4 is the correct answer. -24= -4/6
