What is the mean of Variable A? Express answer to one decimal place. Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Variable A. The vertical axis is labeled Variable B. Points are plotted at (two, two), (two, eight), (four, three), (five, one), (six, three), (seven, five), (eight, six), (nine, two).

Answer:

a). f(0) = 4

b). f(6) = 8

Step-by-step explanation:

a). When x < 5, piecewise function to be considered,

f(x) = x + 4

Since, x = 0 is less than x = 5

f(0) = 0 + 4

f(0) = 4

b). When 5 ≤ x < 7,

Piecewise function to be considered,

f(x) = 8

Therefore, for x = 6,

f(6) = 8

Answer:

Step-by-step explanation:

You have a 10 gallon jug and a 3 gallon jug and need exactly 5 gallons of water.

This what you do:

- Fill the 3 gallons jug full and pour into the 10 gallons keg

- Repeat the above a second time making a total of 6 gallons of water in the 10 gallons jug.

- Fill the 3 gallons jug a third time and pour into the 10 gallons jug making 9 gallons

- Fill the 3 gallons jug the fourth time and pour into the 10 gallons jug till full leaving 2 gallons of water remaining in the 3 gallons jug.

- Then empty out the 10 gallons jug and pour the 2 gallons of water in the 3 gallons jug into the 10 gallons jug.

- Then, fill the 3 gallons jug again and pour into the 10 gallons jug holding the 2 gallons of water making a total of 5 gallons of water in the 10 gallons jug.

The height of the parallelogram is 4 miles and the base is 14 miles.

What is the area of a parallelogram?

The area of a parallelogram is the product of the base and the height of the figure.

The area of a parallelogram = Base x Height

We have been given that the height is x-5, the base is x+5, and the area of the figure is 56 square miles.

So,

The area of a parallelogram = Base x Height

56=(x-5)(x+5)

Now Multiply x-5 and x+5

56=x²-25

Then Add 25 to both sides

81=x²

Now Take the square root of both sides

x=9

Now We can substitute it into the height and base thus,

Height: 9-5

Base=9+5

Therefore, the height of the parallelogram is 4 miles and the base is 14 miles.
