Answer:
2 2/19
Step-by-step explanation:
5 cases in 2 3/8 hours
The unit rate of cases per hour is calculated by dividing the number of cases by the number of hours.
5/(2 3/8) = 5/(19/8) = 5 * 8/19 = 40/19 = 2 2/19

Answer: ![40\ beats](https://tex.z-dn.net/?f=40%5C%20beats)
Step-by-step explanation:
Knowing the information provided in the exercise, you need to find the Least Common Multiple (L.C.M) in order to solve it.
You can follow these steps:
1- You must descompose 2, 5 and 8 into their prime factors:
![2=2\\5=5\\8=2*2*2=2^3](https://tex.z-dn.net/?f=2%3D2%5C%5C5%3D5%5C%5C8%3D2%2A2%2A2%3D2%5E3)
2- And finally, you must multiply the commons and non commons with the highest exponent:
![L.C.M=2^3*5=40](https://tex.z-dn.net/?f=L.C.M%3D2%5E3%2A5%3D40)
Therefore, the answer is: ![40\ beats](https://tex.z-dn.net/?f=40%5C%20beats)

Answer:
Mean of bagel
Step-by-step explanation:
Working out each of the statically summaries Given in the option :
Mean of muffin :
Mean = Σx / n
n = sample size
(61 + 20 + 32 + 58 + 62 + 61 + 56) / 7
= 350 / 7
= 50
Mean of bagel :
Mean = Σx / n
n = sample size
(34 + 45 + 43 + 42 + 46 + 72 + 75) / 7
= 357 / 7
= 51
Hence, from the result obtained, we could see that the value of 51 summarizes the mean of bagel.
