X=83
Step by step
You first add up all of the angles in a 6 sided polygon they equal to 720 degrees so if you add up all of the angles it equals to 637. After that you do 720 minus 637 and then you get your answer which is 83

Answer:

x=83º

Step-by-step explanation:

The interior angle sum of a Hexagon is 720º

146+169+59+129+134+x=720

x=720-637

x=83

Mr. Sanchez’s class sold 51 snickers and Mr. Kelly’s class sold 31 bottles of fruit juice.

Step-by-step explanation:

Step 1:

Assume x is the number of snickers sold and y is the number of fruit juices sold. It is given that both the classes sold 82 items in total. so

x + y = 82, take this as equation 1.

It is also given they both earned $115.56 out of which snickers sold for $1.50 each and fruit juice sold for $1.26 each. So,

1.50x + 1.26y = 115.56, take this as equation 2.

Step 2:

Now we solve these equations.

Equation 1 can also be, y = 82 - x, take this as equation 3.

Substitute equation 3 in 2,

1.50x + 1.26(82-x) = 115.56,

1.50x + 103.32-1.26x=115.56.

Taking the known values to the right and keeping the unknown x values on the right, we get

0.24x = 115.56-103.32 = 12.24

0.24x = 12.24, x = 51.

Substitute this is equation 1,

x + y = 82, y = 82 - x, y = 82 - 51 = 31.

So Mr. Sanchez’s class sold 51 snickers and Mr. Kelly’s class sold 31 bottles of fruit juice.

What does a residual value of –4.5 mean in reference to the line of best fit?
Step2247 [10]

Answer:

The residual value is the difference between the observed value (from the scatter plot) and the predicted value (from the line of best fit).


Step-by-step explanation:

The residual value is the difference between the observed value (from the scatter plot) and the predicted value (from the line of best fit).

Residual Value = Observed Value - Predicted Value

<em>Since the residual value of -4.5 is negative, we can say the predicted value is larger than the observed value. In other words, the line of best fit is "above" the scatter plot point in that specific point.</em>
