Answer:
a) 910
b) 828100
c) 144320
Step-by-step explanation:
a. ∑y
This is the sum of all values of y. So
b. (∑y)^2
This is the square of the sum, so the square of 910, that we found in the previous item.
910² = 828100
c. ∑y^2
This is the sum of the squares of each amount spent. So
What number, when five is subtracted from it equals twelve
That quadrilateral is a parallelogram. Parallelograms have 4 sides and the opposites side are parallel to each other.
Answer: p = 75 + 250
Equation of the situation, in slope-intercept form is given as .
Where,
b = y-intercept
m = slope
n = number of computers sold
p = total cost
All we need to find is the value of m and b.
Using two pairs from the table of values, (4, 550) and (6, 700):
Substitute n = 4, p = 550, and m = 75 in , and find the value of b.
Subtract 300 from each side
b = 250
Substitute m = 75, and b = 250 in
✅Equation that represents the situation would be:
