Answer:

4.88

Step-by-step explanation:

The actual mean is 4.88 to the nearest hundredth. She either approximated the sum of elements to 40 instead of 39 or she approximated the actual mean to the nearest whole number.

I think she gave an approximated average or a rounded average, but I am not sure.

jerry is a judge. He hears 5 cases every 2 3/8 hours. Jerry hears caese at a constant rat. How many cases does he hear per hour

faust18 [17]

Answer:

The number of cases heard by Jerry per hour is $2\frac{21}{500}$

Step-by-step explanation:

The rate of hearing the cases is 5 cases in 2 3/8 hours.

Now, $2\frac{3}{8} = 2+\frac{3}{8} = 2 + 0.375 = 2.375$

⇒The judge hears 5 cases in 2.375 hours.

So, the number of cases per hour = $= \frac{\textrm{Total Number of cases heard}}{\textrm{Number of Hours}} = \frac{5}{2.375}$

= 2.105

Also, $2.105 = 2 + 0.105 = 2 + \frac{105}{1000} = 2+\frac{21}{500} = 2\frac{21}{500}$

Hence, the number of cases heard by Jerry per hour is $2\frac{21}{500}$

I'm pretty sure it would be none of these because1/4*5=1 and 1/4 then it would be 6 and 1/4 then it would be 31 and 1/4
