The residual value comes out to be 2.94 cm and height is 157.06 cm
<u>Explanation:</u>
The regression equation is calculated at the first step.
height = 105.08 plus 2.599 multiply foot length
At foot length = 20cm, height = 105.08 plus 2.599 multiply 20
= 157.06 cm
Residual = Actual minus predicted value = 160 minus 157.06
=2.94 cm
B) The residual standard deviation generally gives a sense of the goodness of fit of goodness of regression equation on our data. The magnitude tells us that how much will be predicted values from model will vary from actual values. the linear model is justified.
Answer:
The total amount she will pay after taxes is $339.58
Step-by-step explanation:
The Total cost of the speaker plus tax = $349
The tax rate applied = 2.7%
Tax payable = $349 * 2.7% = $9.423
The tax amount on the speaker is Tricia = $9.423
Thus, the total amount she will pay after taxes (i.e. paying $9.423) for purchase of the Speaker will be = $349 - $9.423 = $339.58.
The original price of the speaker excluding tax is $339.58.
Answer:
36
Step-by-step explanation:
18 miles per hour so for 2 hours which is double, she should have traveled 36 miles.
Good Luck!
Let y = 0
0 = 2x^2 + 7x + 3
Using the quadratic formula, we get x = -3 and x = -1/2.
But what are they midpoints of? AFE, BFC, CEF,AFB?
