Answer:
Markup: 8%
Explanation:
Amount of markup:
70.20−65.00=5.20
Markup as a percentage of original price
5.2065.00×100=8
B + 12.5x = 400, where b is the base salary and x is the amount of subscriptions he needs to sell.
Options :
(A.) y=558-273x (B.) y=264+142x (C.) y = 55.8 +2.79x (D.) y= -26.4-1.42x
Answer:
C.) ŷ = 2.79X + 55.8
Step-by-step explanation:
Given the data:
cost (x): 9 2 3 4 2 5 9 10
Number of products sold: 85 52 55 68 57 86 83 73
Using the online regression calculator to generate a linear regression plot of the given data: the model obtained is given below
ŷ = 2.79X + 55.8
With y being the predicted or dependent variable
Slope or gradient of the line = 2.79
X = the independent variable
55.8 = the intercept.
Answer:
-0.9
Step-by-step explanation:
The average rate of change of the exponential equation from x = 3 to x = 6 is 4.55
<h3>How to determine the average rate of change?</h3>
The function is given as:
When x = 3, we have:
When x = 6, we have:
The average rate of change is then calculated as:
This gives
Evaluate
m = 4.55
Hence, the average rate of change of the exponential equation from x = 3 to x = 6 is 4.55
