A suitable probability calculator will show that probability to be .135905122.
_____
Your class extends from 1 standard deviation above the mean to 2 standard deviations above the mean. The empirical rule puts that probability at ...
... (1/2)(95% - 68%) ≈ 13.5%
The empirical rule tells you 68% of observations lie within 1 standard deviation of the mean, and 95% lie within 2 standard deviations. Then the number that lie between 1 and 2 standard deviations from the mean will be the difference of these values. You want the values in the region above the mean only, so you only want half the difference just described.
Answer:
Hexagon
Step-by-step explanation:
if you plot all the points and connect the lines then you get a six-sided shape which is a hexagon
F(x)=(-1)^2+3
f(x)=1+3
f(x)=4
The slope is 0 because 4 is a constant.
Answer:
162 in
Step-by-step explanation:
Split this shape into two rectangles:
The big rectangle has a base of 16 and a height of 7 (subtract 12-5=7 for height) Multiply base*height to get area of big rectangle:
16*7 = 112 in
The small rectangle has a base of 10 and a height of 5. Mulitply base*height to get area of small rectangle:
10*5 = 50 in
Add both areas together:
112+50= 162 inches
Answer: less than
