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
25.53kg/3h
25.53/3
= 8.51kg/h
She took 10h to make 85.1kg of dough
25.53/3
= 8.51kg/h
She took 10h to make 85.1kg of dough
Answer:
Step-by-step explanation:
y = 3.25x + 1.25
1.25 is y-intercept
3.25 is the slope of a graph.
If x = 0, then y = 1.25
(0, 1.25)
If x = 3, then y = 3.25(3) + 1.25 = 11
(3, 11)
