Answer:
The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88
Step-by-step explanation:
The mean of the data is 83 and the standard deviation is 6.5, find scores within 1 standard deviation of the mean:
Between
83 - 6.5 = 76.5
83 + 6.5 = 89.5
So:
The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88
Answer:
Step-by-step explanation:
<em>d = 52°</em>
<em>e = 77°</em>
<em>f </em>= 180° - ( 52° + 77° ) =<em> 51°</em>
The perimeter is 2+2+6+6+3+3+3+3+3+3+3+3=40, the perimeter is 40 inches
