Answer:
D.) If the mean typing speed of workers from the agency is 60 wpm, the probability of selecting a sample of 50 workers with mean 58.8 wpm or less is 0.267.
Step-by-step explanation:
In this case, the p value is what let's us determine the probability of getting the desired outcome. This would be 60 wpm.
If it is lower than the desired outcome, we know that this inference is not the <em>actual mean </em>of the data.
Answer:
The total amount of lawns to be mowed would be 20 in 35 hours.
Step-by-step explanation:
It takes an hour and 45 minutes to mow one lawn. When you multiply the 7 hours by 5 you get 35 hours. Same thing if you multiply the 4 lawns by 5 you get 20 lawns.
First off, remember PEMDAS. Then replace the variables with the values.
3(2x3)^2
First distribute the exponent to the value on the inside.
3(4x9)
Then multiply the 4 and 9.
3(36)
After that just distribute the 3.
3x36 = 108.
X5, x6, x7, x12.7. It seemed to have been going into a pattern but then stops at the 2680. The pattern would be x5, x6, x7, x8 if the number was 1,680...?
