Answer:
2.28%
Step-by-step explanation:
Given that:
µ = 40 minutes ; σ = 3.5.
x = > 47 minutes
Obtain the standardized score, Z
Zscore = (x - μ) / σ
P(x > 47) = (47 - 40) / 3.5
P(x > 47) = 7 / 3.5
P(x > 47) = 2
P(z > 2) = 0.02275
Hence, Probability that next pizza delivery takes over 47 minutes is 0.02275 = 2.275% = 2.28%
Final Answer is: 2.28%

Step-by-step explanation:
I have 20 lemons. I cut each of them into halves and then cut THOSE halves into some more halves. How many HALVES do I have in all?
Answer:
80
Step-by-step explanation:
If you have 20 lemons then you half them, you can 40 halves, then after you half those haves you get 80.
The lemons are cut to get the total pieces of 80.
What is fraction?An element of a whole is a fraction. The number is represented as a quotient in mathematics, where the numerator and denominator are divided.
Calculation for the fraction of the lemons cut:
Let 'x' the total number of lemons.
x = 20
As, the all lemons are cut in halves.
So, the quantity of the lemons are multiplied by 2.
2x = 2×20 = 40
The new value of x becomes 40 now.
Now, again the lemons are cut into halves.
2×40 = 80
Therefore, the total number of lemons after cutting are 80.

A television channel broadcasts a baseball game every day. Yesterday's broadcast showed the game for 2 5/6 hours and commercials for 2/3 hour. At this rate, how many hours does the television channel show a game for every hour it shows commercials during its broadcasts?
Answer:
4.25 hours
Step-by-step explanation:
Given that :
Game broadcast time = 2 5/6 hours = 17/6 hours
Commercials time = 2/3 hours
2/3 hours of commercials = 17/6 of game broadcast
1 hour of commercials = x hours of game broadcast
Cross multiply ;
(2/3)x = 17/6
2x * 6 = 17 * 3
12x = 51
x = 51 / 12
x = 4.25
For every hour it shows commercials, game is broadcasted for 4.25 hours
