You have to calculate the probability that it lands on 4. There are 2 possibilities from the 8 that it lands on 4. So the chance is 2/8, which is the same as 4/16
Ab= 28
(bc)^3= -42875
-3c^2= 225
I hope it's right..
Answer:
Fail :b
Step-by-step explanation:
In system A, the first equation multiply by 4
8x - 4y = 12 (1st)
3x + 4y = 10 (2nd)
--------------------add
11x = 22
So answer is B.
Answer:
The weighted average is of 69.94.
Step-by-step explanation:
Weighted average:
The weighed average is found multiplying each grade by its respective weight.
The grades, and weights are:
67 on the lab, with a weight of 23% = 0.23
69 on the first major test, with a weight is 21.5% = 0.215
85 on the second major test, with a weight is 21.5% = 0.215.
63 on the final exam, with a weight of 34% = 0.34.
Weighted average:

The weighted average is of 69.94.
