If you want to calculate the mean of several products, there is an easy way to do it - just add all of those numbers and divide the product by the number of items.
So, here is how to do it:
10,126 + 9,999 + 12,398 + 12,007 + 4,567 = 49,097
Now divide that number by 5 (the number of numbers):
49,097 / 5 = 9,819.4
The correct answer is 9,819.4
Area of a triangle = 1/2 Base x perpendicular height
1/2 (8.6x6.2) = 26.66 ft
Answer: y = 2x + 14 x is the number of weeks. 14 (b) was his original performance in miles jogged per week. y is the expected performance.
Sketch attached.
Step-by-step explanation: Given John's current performance, it is likely that he was able to jog some number of miles per week, the "b" in slope-intercept form. To calculate:
30 = 2(8) + b
30 = 16 + b
30 - 16 = b
14 = b
Substitute into the slope intercept equation:
y = 2x + b
Answer:
11 months
788 disc
Step-by-step explanation:
Let
x = number of months
Fry's Electronics;
= 920 - 12x
Blu-ray discs:
= 502 + 26x
Equate both equations
920 - 12x = 502 + 26x
920 - 502 = 26x + 12x
418 = 38x
x = 418/38
x = 11 months
number of months = 11
Substitute 11 into any of the equation
Fry's Electronics;
= 920 - 12x
= 920 - 12(11)
= 920 - 132
= 788 disc sold in that months
