1 as they flipped a 6 sided cube and want to know the probability of rolling a 5
6-5=1
The answer is 1
Given:
100 students:
pass = + 4
fail =+ 0
90 students passed: 90 * 4 = 360
10 students failed: 10 * 0 = 0
mean: 360 / 100 = 36
standard deviation:
36 - 4 = 32 ⇒ 32² = 1,024 * 90 = 92,160
36 - 0 = 36 ⇒ 36² = 1,296 * 10 = 12,960
92,160 + 12,960 = 105,120
105,120 / 100 = 1,051.20 ⇒ variance
Standard deviation = √1,051.20 = 32.42
You can turn :
4 divided by 1/3 INTO 4 times 3
It's the same thing. Then make four groups of 3
I think -23/4 hope it helps
They don't have the same x-coordinates or the same y-coordinates so it is neither.
