<u>Answer:</u>
she spent total price of 13 on the picnic table
<u>Explanation: </u>
Original price of the table = 40
Since she paid 10% of the sale tax after the sale then the total amount she spend is
Discount = (discount percentage – sale tax ) × original price
= (75% -10%) × 40
= 65 % ×40
=
=26
Hence after the discount amount
Original price – discount price
= 40-26 = 13
Hence she spent total price of 13 on the picnic table
Answer:
C. 28 ft³
Step-by-step explanation:
The general formula for the volume of a pyramid:
V = , where B = the area of the base and h = height of the pyramid
Since the base is a rectangle, we can find area using the formula:
A = l x w or A = 3 x 4 = 12 ft²
Using B = 12 and h = 7:
V =
V = 28 ft³
Using Visual inspection, the model which fits the data in the distribution better is the power function.
The power and linear functions can of the data can both be modeled using technology,
<u>Using Technology</u> :
The power function in the form which models the data is
The linear function in the form which models the data is
- Where A = intercept and B = slope
- From the model, correlation coefficient given by the power and linear models are 0.999 and 0.986 respectively.
- Hence, the power model is a better fit for the data than the linear model.
Therefore, Inspecting the models visually, the power function fits the data better as the points on the curve are closer to the regression line than on the linear model.
