<u>Answer-</u>
<em>Quadratic Regression</em><em> model best fits the data set.</em>
<u>Solution-</u>
Taking x as input variable and y as output variable, regression models were obtained by using Excel.
As we can be seen that, the values of y is neither consistently increasing or decreasing ( as 13 > 8 > 7.5 < 9 < 12 ), so exponential growth and exponential decay are of no use (because in exponential function the growth or decay rate is constant).
And also, it can not be linear, as the rate of change of y is not constant.
As we can obtain the correct regression model, by considering Co-efficient of Determination (R²). The value of R² ranges from 0 to 1. The more closer its value to 1, the better the regression model is.
From the attachment, it can be observed that,


As the value of R² of the Quadratic Regression is more closer to 1, so that should be followed.

Answer:
<em>180</em>
Step-by-step explanation:
You need to find 3/8 of 480.
To find a fraction of a number, multiply the fraction by the number.
3/8 of 480 =
= 3/8 * 480
= 3/8 *480/1
= (3 * 480)/(8 * 1)
= 1440/8
= 180

Answer:26.9 feet
Step-by-step explanation:

x\tan 70=74
xtan70=74
Cross multiply.
\frac{x\tan 70}{\tan 70}=\frac{74}{\tan 70}

Divide each side by tan 70.
x=\frac{74}{\tan 70}=26.9338\approx 26.9\text{ feet}
x=

=26.9338≈26.9 feet
Type into calculator and roundto the nearest tenth of a foot.
