Question

((Please show/explain work))

The table below shows results of spinning the spinner 65 times. Based on the experimental data, which of the following is NOT true?
A. Out of 100 spins, the spinner is expected to land on 5 approximately 23 times.
B. Out of 200 spins, the spinner is expected to land on three 40 times.
C. Out of 300 spins, the spinner is expected to land on four approximately 55 times.
D. Out of 400 spins, the spinner is expected to land on two 60 times.

Answer 1

i saw this before the awnser is b i saw this earlier

Explanation:

Answer 2

Out of 400 spins, the spinner is expected to land on two 60 times is Not True. option D is correct.

How the equivalent values of time in spinning experiment is determined.

Given

Numeral 1 2 3 4 5

Times Landed 14 11 13 12 15

Total time landed = 14 + 11 + 13 + 12 + 15 = 65

Let's analyze each option

Option A

If 65 spins landed five 15 times

100 spins will give 15*100/65

= 1500/65

= 23 times approximately, true.

Option B

If 65 spins landed three 13 times

200 spins will give 13*200/65

= 2600/65

= 40 times, true.

Option C

If 65 spins landed four 12 times

300 spins will give 12*300/65

= 3600/65

= 55 times approximately, true.

Option D

If 65 spins landed two 11 times

400 spins will give 11*400/65

= 8800/65

= 135 approximately.

This not 60 times, Not true

Out of 400 spins, the spinner is expected to land on two 60 times is Not True. option D is correct.
