Answer:
Rachel earn $85 in 10 hours.
Step-by-step explanation:
Rachel earned $34 in 4 hours at her job today. It means we can find his earning in 1 hour.
1 hour = $(34/4)
= $8.5
He earns $8.5 in an hour.
To find his earning in 10 hours, multiply $8.5 by 10. So,
Earning = $8.5 × 10
= $85
Hence, Rachel earn $85 in 10 hours.
Answer:
69.1
Step-by-step explanation:
<em>Mean height of 14 students = 69.0 inches</em>
<em>Mean = sum of data/number of data</em>
<em>69 = sum of data/14</em>
<em>sum of data = 966</em>
<u>FOR NEW MEAN:</u>
<em>Height of additional student = 70.5</em>
Mean = sum of data/ number of data
Mean = 966+70.5/14+1
Mean = 1036.5/15
Mean = 69.1
Therefore, the mean height of the 15 students in the class is 69.1
