Answer:
Paula will arrive at her house at 15:20.
Step-by-step explanation:
Since Paula sets off from home at 13:20 and drives to Taunton for km at a speed of km / h, and after 40 minutes, she drives back home on the same route, but drives twice as slowly, to determine at what time Paula will arrive back home, the following calculation must be performed:
13:20 + 00:40 + (00:40 x 2) = X
14:00 + 1:20 = X
15:20 = X
So, Paula will arrive at her house at 15:20.

Answer:
91% of the time the auto will get less than 26 mpg
Step-by-step explanation:
Think of (or draw) the standard normal curve. Mark the mean (22.0). Then one standard deviation above the mean would be 22.0 + 3.0, or 25.0. Two would be 22.0 + 2(3.0), or 28.0. Finallyl, draw a vertical line at 26.0.
Our task is to determine the area under the curve to the left of 26.0.
Using a basic calculator with built-in statistical functions, we find this area as follows:
normcdf(-100, 26.0, 22.0, 3.0) = 0.9088, which is the desired probability: 91% of the time the auto will get less than 26 mpg.
Sorry, i think you forgot to place the second function. please do so!
