Answer:

See explanation

Step-by-step explanation:

Required

The average weight produced

The question is incomplete, as the required cells are not given and there are other missing details.

However, I will give a general explanation of calculating average in Excel

The required formula is:

=AVERAGE(Cell Range)

Assume the cells that contain the boxes are: cells A10 to A10010

The average will be calculated as:

=AVERAGE(A10:A10010)

The perimeter of a rectangle is 37. The length is 1 less than 12 times the width. What is the length and width of the rectangle

iren [92.7K]

Width = W
Length = 12W - 1
Perimeter = 2L + 2W = 37

In the perimeter equation substitute the length equation in for L to get the equation in terms of W
2L + 2W = 37
2(12W - 1) + 2w = 37

Distribute
2(12W - 1) + 2w = 37
24W - 2 + 2w = 37
26W = 39
W = 3/2 = 1.5
Width = 1.5

Lastly, solve for length
L = 12W - 1
L = (12 • 1.5) - 1
L = 18 - 1
L = 17
Length = 17

Coordinate Planes

Coordinates (x, y)
Slope Formula: $\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}$

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, 4)

Point (2, 9)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m.

Substitute in points [Slope Formula]: $\displaystyle m = \frac{9 - 4}{2 + 1}$
[Order of Operations] Simplify: $\displaystyle m = \frac{5}{3}$
