Answer:
B
Step-by-step explanation:
First, we are decreasing the number so it has to be a decrease.
Next, we divide 7/31 and get around 0.23, which also represents 23 percent.
This only shows that 7 is 23 percent of 31, so we need to find the decrease by seeing the difference of 100 and 23.
We get 100 - 23 = 77, and because it is a decrease we get B.
For a parallelogram, the parallel sides must be the same length. This means you can set their lengths equal to each other. Get like terms on the same side to calculate x.
3x-5=2x+3
3x-5+5=2x+3+5
3x=2x+8
3x-2x=2x-2x+8
x=8
x=8
Answer:
B
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile.
The upper quartile is the right side value of the box
The lower quartile is the left side value of the box
upper quartile = 61 and lower quartile = 39
IQR = 61 - 39 = 22 → B
