Answer:
The tax on a bike is $22.75. If the rate is 6.5%, how much was the original price of the bike?
x = Price of bike
6.5% * x = 22.75
flip it
x = 22.75 / 6.5%
x = 350
Step-by-step explanation:
Answer:
see explaination
Step-by-step explanation:
1) Lets form the regression equation from the data results
Size = -1.633+ 0.4485*FamilyIncome + 4.2615*FamilySize - 0.6517*Education
-1.633+ 0.4485*40+ 4.2615*4 - 0.6517*13 =24.88
2) For the model to be reasonable, we must check the significant F stat from the anova table( see attachment)
From the table at attachment we can deduce; as the significant F is less 0.01 , we can safely conclude that the model is signifcant
3) all variables that have a p value less than 0.01 can be safely removed from the model as they do not contribute sigificantly from the model
so education can be removed from the model
Answer:
A
Step-by-step explanation:
Answer:
y - 3 = ⁵/₂(x - 2) {the point-slope form of the equation}
y = ⁵/₂x - 2 {the slope-intercept form of the equation}
5x - 2y = 4 {the standard form of the equation}
Step-by-step explanation:
The point-slope form of equation is: y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope.
m = ⁵/₂
(2, 3) ⇒ x₀ = 2, y₀ = 3
So, the point-slope form of the equation:
y - 3 = ⁵/₂(x - 2)
Therefore:
y - 3 = ⁵/₂x - 5 {add 3 to both sides}
y = ⁵/₂x - 2 ← the slope-intercept form of the equation
-⁵/₂x + y = - 2 {multiply both sides by (-2)}
5x - 2y = 4 ← the standard form of the equation
