Answer:
The total number of ways are 315.
Step-by-step explanation:
Consider the provided information.
A certain university will select 1 of 7 candidates eligible to fill a position in the mathematics department.
Therefore the number of ways are:
ways
There are 7 ways to fill math position.
2 of 10 candidates eligible to fill 2 identical positions in the computer science department.
Therefore the total number of ways are:
Hence, there are 45 ways to fill computer science position.
Total number of ways = 7 × 45 = 315 ways.
Hence, the total number of ways are 315.
An=a1+d(n-1)
d=3
a12=36
a12=a1+3(12-1)
36=a1+3(11)
36=a1+33
minus 33 both sides
3=a3
C is answer
There are 25 students in Mrs. Venetozzi’s class at the beginning of the school year, and the average number of siblings for each student is 3. A new <span>student with 8 siblings joins the class in November. What is the new class average for number of siblings? Round your answer to the nearest hundredth.
The solution will be 25 x 3 = 75 + </span>8 = 83 / 26 = 3.192
Hence the number becomes <span>3.20</span>
Answer:
$9.75
Step-by-step explanation:
I divided $78 by 8 people and that is how I got this answer.
7/5 = 63/x
cross multiply
(7)(x) = (63)(5)
7x = 315
x = 315/7
x = 45 <=== if there were 63 schooners, then there were 45 skiff's
