Vitek1552 [10]

Answer:

0.4 ounces

Step-by-step explanation:

In a day

Miguel is to feed Chester ,

Chester can eat 3/4 of an ounce for each pound of body weight.

Chester weighs 6.8 pounds

x = 6.8 × (3/4) ounces

x = 5.1 ounces

Chester is to be fed 5.1 ounces of food each day.

The amount of food left after 1 day

= 5.5 ounces - 5.1 ounces

= 0.4 ounces

Hence, 0.4 ounces of food is left after 1 day

Calculate the mean,median,and mode of the following set of data. Round to the nearest tenth 10,1,10,15,1,7,10,1,6,13
lions [1.4K]
Let's start with the mean. 

To find the mean of a data set, add all the numbers, then divide by the number of numbers there are. 

10 + 1 + 10 + 15 + 1 + 7 + 10 + 1 + 6 + 13 = 74
74/10 = 7.4

The mean is 7.4

Now for the median.

To find the median put all the numbers in order, then find the middle number.

1, 1, 1, 6, 7, 10, 10, 10, 13, 15

The number in between 7 and 10 is 8.5
The median is 8.5

And finally, the mode.

To find the mode, find the number that appears the most. 

1, 1, 1, 6, 7, 10, 10, 10, 13, 15

In this case, there are two modes. 1, and 10.

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)
