Answer:
The number of pies baked in the two years = ( k + 145) pies
Step-by-step explanation:
Here, we are interested in writing an expression for the total number of pies baked in the two years.
Last year, the number of pies baked = 145
This year the number of pies baked = k
Thus, the total number of pies baked in the two years will be ( k + 145) pies

Hello!</h2>
The answer is:
It will take 18 hours for the return trip.
<h2>
Why?</h2>
To calculate how long does it take for the return trip, we need to calculate the distance between it destination and the starting point.
We know that the ship sails at 15 miles per hour (mph) for 6 hours, so, calculating the distance we have:
We know that the distance between the destination and the starting point is 90 miles, now, to calculate how long does it take the return trip, we need to use the motor speed rate which is equal to 5 miles per hour (mph), so, calculating we have:
Therefore, we have that it will take 18 hours for the return trip.
Have a nice day!
9^4 = 6,561. 10^4 = 10,000. 6,561 + 10,000 = 16,561
Answer:
(a) The p-value is 0.9554
(b) We cannot reject the null hypothesis at the significance level of 0.06
Step-by-step explanation:
We are dealing with a lower-tail alternative . Because the test statistic is z = +1.7 which comes from a normal distribution, the p-value is the probability of getting a value as extreme as the already observed.
(a) P(Z < +1.7) = 0.9554
(b) The p-value is very large, and 0.9554 > 0.06, so, we cannot reject the null hypothesis at the significance level of 0.06
