Answer:
y = 41.603X + 3.582
Step-by-step explanation:
Given the data:
Week ___Price ____ Sales
1 _______.33 _______20
2 ______ .25 _______ 14
3 ______ .44 _______ 22
4 ______ .40 _______ 21
5 ______ .35 _______ 16
6 ______ .39 _______ 19
7 ______ .29 _______ 15
Using the linear regression calculator ; The regression equation obtained is :
y = 41.603X + 3.582
Where ;
y = sales (predicted variable)
x = price (predictor variable)
Slope = 41.603
Intercept = 3.582
Answer:
work = force × distance
Therefore,
work = 3200N × 16m
= 51200J
So,
Power = Work done/ time taken
Therefore,
Power = 51200/30
= 1706.6 ~ 1707W
Hope it helps!
Based on the function given, the domain of f(x) is -18 ≤ x ≤ 10 and the range is 16 ≤ f(x) ≤ 95
<h3>What are the domain and range?</h3>
The domain of a function is found by looking at a graph from left to right. This means that x will be equal to or greater than the smallest x value and less than or equal to the largest x value.
Domain is therefore:
-18 ≤ x ≤ 10
The range can be found by looking at the y value. The value if f(x) will be equal to or greater than the smallest y value and less than or equal to the largest y value.
Range is:
16 ≤ f(x) ≤ 95

Answer:
Step-by-step explanation:
y=9 when x=8
y=18 .............x=?
y=9/8 *8= 9/8 *x
x=y :9/8=18 :9/8=18*8/9=16
so b is correct
