Answer:

9) 28% decrease

13) 100% decrease

15) $9.90

17) 272 pages

18) 42 members

19) $27,840

20) 1,863 songs

Step-by-step explanation:

9) Subtract 68 from 95 and you get 27.

Divide 27 by 95 and you get 0.284...

Multiply 0.284... times 100 and you get 28.4.

Round to 28%

13) If a number goes from itself to zero, it's a 100% decrease

15, 18, 20) Divide percent by 100.

Multiply the percent by the initial number.

Add the new number to the initial number

17 and 19) Do everything you did in 15, 18, and 20, but instead of adding the new number to the initial number, subtract it to the initial number

Philip and Veronica are in band together. He asked her a statistical question. Which question

Karo-lina-s [1.5K]

The answer would be D. How long are the songs you practice playing on your instrument?

Statistical questions are ones that will show variability. The first three questions will have a straight answer. The last one however will have data that varies, since most likely every song is not the same length.

The path of a race will be drawn on a coordinate grid like the one shown below. The starting point of the race will be at (−5.4,

k0ka [10]

There are 4 quadrants in a coordinate plane

The starting point is in the second quadrant, while the finishing point is in the fourth quadrant.
The starting point is a reflection of the checkpoint across the y-axis

Part A

The points are given as:

$Start = (-5.4,3)$

$Finish = (3,-5.4)$

For the starting point, the x-coordinate is negative, while the y-coordinate is positive.

This implies that the starting point is in the second quadrant

For the finishing point, the x-coordinate is positive, while the y-coordinate is negative.

This implies that the finishing point is in the fourth quadrant

Part B

The checking point is given as:

$Checking = (5.4,3)$

The starting point is given as:

$Start = (-5.4,3)$

Notice that the y-coordinate of both points are the same, but the x-coordinates are negated.

This means that the starting point is a reflection of the checkpoint across the y-axis, and vice versa
