Answer:
Step-by-step explanation:
Hello!
Given the variables
Y: Cost of a previously owned Camry.
X: Mileage of a previously owned Camry.
Scatter plot in attachment.
As you can see in the scatter plot, the price of the previously owned Camry decreases as their mileage increases this suggest that there is a negative linear regression between these two variables.
Hypothesis test for the y-intercept
H₀: β₀ = 0
H₁: β₀ ≠ 0
Level of significance α: 0.01
p-value < 0.0001
The decision is to reject the null hypothesis. You can conclude that the population mean of the cost of a previously owned Camry, when the mileage is zero, is different from zero.
H₀: β = 0
H₁: β ≠ 0
Level of significance α: 0.01
p-value: 0.0003
The decision is to reject the null hypothesis. You can conclude that the population mean of the cost of a previously owned Camry is modified when the mileage increases in one unit.
Answer:
42 feet squared
Step-by-step explanation:
Answer:
Remember, the formula is the second value minus the first value, divided by the first value times 100.
9. 50% Increase
10. 33% Decrease
11. 200% Increase
To calculate tip, simply move the decimal place 2 to the right and multiply it by the price. For example, If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip.
12. $23.00
13. $10.50
Answer:
b = 40 - p
42b + 52p = 350
Step-by-step explanation:
Given : No. of small blue pom-pom boxes = b
No. of large orange pom-poms = p
cost of 1 box of blue pom pom = $42
cost of one large orange pom-pom box = $52
Solution:
Since we are given that the company has only 40 boxes
⇒b+p=40
⇒b=40-p
Since cost of 1 box of blue pom pom = $42
So, cost of b box of blue pom pom = $42b
Since,cost of one large orange pom-pom box = $52
So,cost of p large orange pom-pom box = $52p
We are also given that the company plan to make $350
⇒42b+52p=350
Hence Option b is correct
b = 40 - p
42b + 52p = 350
