IQ Scores have a bell-shaped distribution with a mean of 100 and a standard deviation of 15. What percentage of IQ scores are between 70 and 130?
<span>Solution: </span>130 – 100 = 30 which is 2(15). Thus, 130 is 2 standard deviations to the right of the mean. 100 – 70 = 30 which is 2(15). Thus, 70 is 2 standard deviations to the left of the mean. Since 70 to 130 is within 2 standard deviations of the mean, we know that <span>about 95% of the IQ scores would be between 70 and 130.</span>
Well for starters the America’s has the more advantage because the Columbian trade brought slaves from the west of Africa new crops animals and spices to the Americas while most of the Afro Eurasian suffer from sickness and thrown over board.

Answer:
Option D. 274.75 units²
Explanation:
From the question given above, the following data were obtained:
Radius (r) = 3.5 units
Height (h) = 9 units
Surface Area (SA) =?
The surface area of the cylinder can be obtained as follow:
SA = 2πr (h + r)
NOTE: Pi(π) = 3.14
SA = 2 × 3.14 × 3.5 × (9 + 3.5)
SA = 21.98 × 12.5
SA = 274.75 units²
Thus, the surface area of the cylinder is 274.75 units²
