Storing milk at temperatures colder than 35°F can affect its quality of taste. However, storing milk at temperatures warmer than

puteri [66]

t > 35 and t <40

So, Option A is correct.

Step-by-step explanation:

This is the question of compound inequality

Since the temperature of milk should be greater than 35 and the temperature should be less than 40 for keeping the quality of milk.

So, Representing it in inequality the union of both conditions we get:

t > 35 and t <40

So, Option A is correct.

Use the given data to find the equation of the regression line. x 44 44 11 11 55 y 66 55 negative 1−1 negative 3−3 88 ModifyingA

Temka [501]

Answer:

$y=1.98 x -24.34$

Step-by-step explanation:

Assuming the following data

X: 44, 44, 11, 11, 55

Y: 66, 55, -1, -3, 88

We want to find a linear model $Y= mx +b$

For this case we need to calculate the slope with the following formula:

$m=\frac{S_{xy}}{S_{xx}}$

Where:

$S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}$

$S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}$

So we can find the sums like this:

$\sum_{i=1}^n x_i =44+44+11+11+55=165$

$\sum_{i=1}^n y_i =66+55-1-3+88=205$

$\sum_{i=1}^n x^2_i =7139$

$\sum_{i=1}^n y^2_i =15135$

$\sum_{i=1}^n x_i y_i =10120$

With these we can find the sums:

$S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}=7139-\frac{165^2}{5}=1694$

$S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}=10120-\frac{165*205}{5}=3355$

And the slope would be:

$m=\frac{3355}{1694}=1.98$

Nowe we can find the means for x and y like this:

$\bar x= \frac{\sum x_i}{n}=\frac{165}{5}=33$

$\bar y= \frac{\sum y_i}{n}=\frac{205}{5}=41$

And we can find the intercept using this:

$b=\bar y -m \bar x=41-(1.98*33)=-24.34$

So the line would be given by:

$y=1.98 x -24.34$
