    Answer:

    57

    Step-by-step explanation:

    This question actually had a data set, but i think the person who posted it didn’t put one. The numbers were “21, 30, 39, 43, 58, 67”. If this was the data set, we can say our answer is 57.

    To find the mean, you need to add all of the numbers together and divide it by the total number of numbers. So for this problem, we would add 21 + 30 + 39 + 43 + 58 + 67 and then divide it by 6. We get 43. Knowing that we need to find the 7th day, we can use the answer that I have, 57.

    57 + 21 + 30 + 39 + 43 + 58 + 67 = 315. Now, 315 divided by 7 is 45.
