Answer:
16%
Step-by-step explanation:
The indicated probability is actually the area under the standard normal curve to the left of the mean. I used the function normalcdf( on my TI-83 Plus calculator to find this quantity:
normalcdf(-1000,85,90,5) = 0.1587.
Note #1: This quantity (area / probability) is the area to the left of 85.
Note #2: by the Empirical Rule, 68% of data lies within 1 s. d. of the mean, so the area between the mean (90) and the score (85) is half of 68%, or 34%. Subtracting this from 50% (the area to the left of the mean), we get 16%, which is roughly equivalent to the 0.1587 we got earlier.
Answer:
2800 cm^3, or 2.8 liters
Step-by-step explanation:
The base of the tank remains 14 cm × 25 cm. The remaining height is 15 -7 = 8 cm, so the remaining volume is ...
(14 cm)(25 cm)(8 cm) = 2800 cm^3 = 2.8 liters
_____
1 liter = 1000 cm^3
Answer:
4 out of 20 if I'm not mistaken
Step-by-step explanation:
Add all the numbers and then you get 20 and there are 4 yellow marbles so 4 out of 20
C=2(pi)r use this equation with 9 in place of r
