You would solve it in two parts.
4*n = 44 Divide by 4
4n/4 = 44/4
n = 11
=============
z^m * z^2 = z^9
When the bases are the same (on the left) the powers on the left add
m + 2
The powers on the left side of the equation are the same as the powers on the right when the bases are the same.
m + 2 = 9 Subtract 2 from both sides.
m + 2 - 2 = 9 - 2
m = 7

m = 7
n = 11

Answer:61.7
Step-by-step explanation:
maths
Just matter of combining like terms
6x - 7 - 11x + x =
(6x + x - 11x) - 7 =
(7x - 11x) - 7 =
- 4x - 7 <===
Answer:
B) 0.283
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
25% of the students drive themselves to school.
This means that 
Class of 18 students
This means that 
What would be the probability that at least 6 students drive themselves to school?
This is

In which

So









Closest option is B, just a small rounding difference.
