A 10-yr-old competes in gymnastics. For several competitions, she received the following "All-Around" scores: 35.5, 36.3. 36.6,
Delicious77 [7]

Answer:

The child needs a score of 37.2 to move up to the next level of the competition.

Step-by-step explanation:

The mean is the sum of all scores divided by the number of competions. So

M = \frac{S}{T}

In which S is the sum of all her scores and T is the number of competitions.

The child has five competions:

Which means that T = 5

She has to get a mean of at least 36.5, so M = 36.5

Her scores are: 35.5, 36.3. 36.6, and 36.9. Her last score, i am going to call x. So

S = 35.5 + 36.3 + 36.6 + 36.9 + x = 145.3 + x

The child needs a score of _____ to move up to the next level of the competition.

This score is x. So

M = \frac{S}{T}

36.5 = \frac{145.3 + x}{5}

145.3 + x = 36.5*5

x = 37.2
