We have to find the lengths of the sides XY and XW:
XY² = ( - 7 - ( - 4 ) )² + ( - 1 - 0 )²
XY² = ( - 7 + 4 )² + ( - 1 )²
XY² = 9 + 1 = 10
XY = √10
XW² = ( - 6 - ( - 4 ))² + ( 6 - 0 )²
XW² = ( - 6 + 4 )² + 6 ²
XW² = 4 + 36 = 40
XW = √ 40 = 2 √10
The perimeter of the rectangle:
P = 2 · √10 + 2 · 2√10 = 2√10 + 4√10 = 6√10
Answer:
C ) 6√10 units.

Suppose the scores of students on an exam are normally distributed with a mean of 244 and a standard deviation of 79. According

Ahat [919]

244 - 165 = 79 . . . . one standard deviation
323 - 244 = 79 . . . . one standard deviation

The range of scores is ±1 standard deviation from the mean. The empirical rule says
68% of scores lie in that range.

Answer:

113.04, 4, 452.16
78.5, 11, 863.5
153.86, 10, 1538.6

Step-by-step explanation:

When calculations are repetitive, I like to let a calculator or spreadsheet do them. Here we have used the formula for the base area:

B = πr² = 3.14×r²

In the second figure, the radius is half the diameter, so is 5 units.

The table in the attachment lists the base area B, the height h (from the figures), and the volume V. These are the values that you need to drag and drop to the boxes in your problem.

V = 113.04 · 4

V = 452.16 units³ . . . showing how the numbers are used in the first figure
