Answer:
1) True
2) False
3) False
4) True
Step-by-step explanation:
1) True
Anything over 100% is larger than the original.
2) False
Since it is 225% bigger, you multiply 4 by 2.25.
4 x 2.25 = 9
3) False
If it is 225% larger, it means that it is 2.25 times larger
4) True
Answer=12.6
QR=9
QP=6
TU=19
TS=?
The triangles are similar, so the following equation can be made
9 6
____=____
19 x
Cross multiply
9x=114
divide both sides by 9
x=12.6 (with the 6 repeating) or 12 2/3
TS=12.6
Median: 23.5
12 and 35 are in the middle so you add them and divide by 2, leaving you
23.5 as your median.
Mean: 41.3
Add all numbers together and divide the sum by the number of numbers added. So all numbers added together equals 413. Divide by ten the nuber of numbers added. 413/10 equals 41.3.
Mode: 99
The number that appears most often. In this case, 99 would be the mode.
Range: 98
The lowest number subtracted from the highest number. 99-1 equals 98.
IQR: 84.75
Hope this helped! :)
R could equal any number, but it has to be higher than 4, because 3+4=7.
