yuradex [85]

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!

Robert spun the fair spinner shown below 1,060 times,
prisoha [69]

Answer:

About 400 times

Step-by-step explanation:

Given

n = 1060

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:

Pr = P(1) + P(3) + P(8)

The spinner is divided into 8 equal segments and each outcome appears once.

So, we have:

Pr = \frac{1}{8}+\frac{1}{8}+\frac{1}{8}

Take LCM and add

Pr = \frac{1+1+1}{8}

Pr = \frac{3}{8}

So, the expected number of times (E) is:

E = Pr * n

E = \frac{3}{8} * 1060

E = \frac{3* 1060}{8}

E = \frac{3180}{8}

E = 397.5

Approximate

E = 398

<em>This means about 400 times</em>
