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
Data: 4,10,11,13,14,15,25,29,33,33,35,43,51,58,64<br><br>

Answer:
m (Slope) = 3
Step-by-step explanation:
Slope formula:
m = (y2 - y1) / (x2 - x1)
= (24 - 3) / (9 -2)
= 21 / 7
=3
