Answer:
Step-by-step explanation:
Both 115 and 145 mph are above the mean. Draw a normal curve and mark these speeds. 115 mph is 1 standard deviation above the mean; 130 would be 2 standard deviations above the mean; and 145 would be 3 s. d. above it.
We need to find the area under the standard normal curve between 115 and 145. This is equivalent to the area under the standard normal curve between z = 1 and z = 3.
I used my TI-83 Plus calculator's DISTR function "normalcdf(" to calculate this area: normalcdf(1, 3) = 0.1573.
The area between z = 1 and z = 3 is 0.1573. In other words, the percentage of serves that were between 115 and 145 mph was 15.73%.
Answer:
9.72 lb
Step-by-step explanation:
Yield = the amount or quantity produced or returned.
Given:
- Yield of eggplant = 81%
- Amount of eggplant purchased = 12 lb
To determine how many pounds of eggplant you will be able to use, calculate 81% of the amount of eggplant purchased.
Therefore, you will be able to use 9.72 lb (nearest hundredth).
