Step-by-step explanation:
when means of more than two groups are to be compared, ANOVA is perferred
We know that the pool drains at a rate of 8 gallons per minute. We can multiply 8*11. 8*11 is 88. We can now subtract 88 from 143. This gives us 55. The swimming pool has 55 gallons of water after 11 minutes.
7n-22 ≥ 64
1. Move constant to the right.
7n ≥ 64 + 22
2. Combine like terms.
7n ≥ 86
3. Divide 7n by 7 to get n alone.
n ≥ 86
4. Divide 86 by 7.
n ≥ 86 / 7 OR n ≥ 12.29
8B and 10 not sure probably centre??
