<span>280 I'm assuming that this question is badly formatted and that the actual number of appetizers is 7, the number of entres is 10, and that there's 4 choices of desserts. So let's take each course by itself. You can choose 1 of 7 appetizers. So we have n = 7 After that, you chose an entre, so the number of possible meals to this point is n = 7 * 10 = 70 Finally, you finish off with a dessert, so the number of meals is: n = 70 * 4 = 280 Therefore the number of possible meals you can have is 280. Note: If the values of 77, 1010 and 44 aren't errors, but are actually correct, then the number of meals is n = 77 * 1010 * 44 = 3421880 But I believe that it's highly unlikely that the numbers in this problem are correct. Just imagine the amount of time it would take for someone to read a menu with over a thousand entres in it. And working in that kitchen would be an absolute nightmare.</span>

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

I will give brainliest!!!
Licemer1 [7]

The equation would be worded as: 2m+16=36.

Solve! Using the subtraction property of equality, 2m=20. Then the division property of equality lets us figure out that m=10.

Hope that helped! Happy SOLVING!
