Answer:
Mean of boiling times = 26.9 seconds
Step-by-step explanation:
Times ella recorded are given as;
24.5 seconds, 23.2 seconds, 29.8 seconds, and 30.1 seconds.
Now, we want to find the mean of these boiling times.
Formula for mean is;
Mean = sum of terms/number of terms
In this question,
number of terms = 4
Sum of terms = 24.5 + 23.2 + 29.8 + 30.1 = 107.6
Thus,
Mean = 107.6/4
Mean = 26.9 seconds

Steps:
1-29f^2/d^4/2f^2= 58f^2/d^4
All i did in step one was simplify D variables then multiplied 29f^2 and 2f^2 together to get 58f^2
d5/58f^4
Answer is A
2 5/16 divided 7/8
Simplify
(37/16) / (7/8)
When dividing by a fraction flip over the fraction and multiply
(37/16) * (8/7)
Multiply numerators, multiply denominators
296 / 112
Reduce the fraction
37/14

Answer:
8 more teachers
Step-by-step explanation:
Since 15% of the committee are parents of students, 45% are teachers from the current high school, 25% are school and district administrators, the total percentage is
→ 15 + 45 + 25 = %85
The remaining percentage is 15, and it is equal to 6 students. Then, the total number of people in the committee is
→ 
= 
→ x = 40
Since %45 of the committee are teachers, the number of teachers is
→ 40(
) = 18
Since %25 of the committee are school and district administrators, the number of school and district administrators is
→ 40(
) = 10
That means, there are 18 - 10 = 8 more teachers
