Answer:
x=23
Step-by-step explanation:
let's make this question into equation form
x increase by 10; or x+10
is equal to 33; or =33
so it would look like this; x+10=33
now we can solve it in reverse
<em>33-10=23</em> so x is 23.
hope this helped, have a great day.

Answer:
C. 40
Step-by-step explanation:
average = (42 + 35 + 51 + 32)/4 = 40
Answer: C. 40
This is what is known as a derangement - an arrangement in which none of the objects maintain their original position.
For example, with the numbers, 1234, in how many ways can they be arranged so that 1 is NOT in first position, 2 is NOT in second position, etc.
Of the 24 possible permutations of four numbers, there are nine possible derangements:
<span><span>2143 2341 2413
3142 3412 3421
4123 4312 4321</span>
So, the probability that no one gets their own trumpet is
9 out of 24 = 3/8 answer is A
