Answer:
Step-by-step explanation:
1) Find the Mean of all the numbers.
3+4+5+7+10+12+15=56
56/7=8 mean is 8
Now We Calculate Standard Deviation:
S=
You take each number from the problem i.e 3,4,5...
and then you subtract the mean from it and then square it.
S=
S=
S=
S=
7 is the amount of data units given in the problem.
120/7=17.1428571429
=4.1403933560541
Nearest hundredth=4.14
The probability of rolling factors of 4 are 4/1 or 2/1
D. 1/4 because imagine splitting that parallelogram in half, and you will see on the first half that half of that half is shaded. So that part is 1/2 and if you add the second half which isn't shaded at all, that's 0/2 so do 1/2 plus 0/2 and you will get 1/4
Converting to exponents we have
( 5^1/3)^1/2
= 5 ^(1/3 * 1/2)
= 5 ^ 1/6
Its the second choice.
