Answer:
C. 8, 15, 17
E. 15, 20, 25
Step-by-step explanation:
You need to take the 2 smaller numbers as in 8 and 15 square it, so 8x8= 64 and 15x15= 225 and then add 64+225= 289 and 17x17=289 so 289=289 ✔
Again square 15 and 20, 15x15=225 and 20x20=400 add them 225+400=625
and 25x25=625 so 625=625 ✔
Hope this helped and good luck!

Answer:
About 400 times
Step-by-step explanation:
Given
See attachment for spinner
Required
Determine the number of times an outcome of 1, 3 or 8 is expected
First, calculate the theoretical probability of 1, 3, or 8
This is calculated as:
The spinner is divided into 8 equal segments and each outcome appears once.
So, we have:
Take LCM and add
So, the expected number of times (E) is:
Approximate
<em>This means about 400 times</em>

It is 90 yds squares because formula for a triangle for area is (length times width) divided by 2. So it would be 180 divided be 2 which is 90 :)
