Find the mean of the first four test scores first.
(Add all numbers in set and divide by how many numbers there are)
81 + 87 + 71 + 89 = 328 / 4 = 82
Then, find the mean with the 85 added as the fifth term.
81 + 87 + 71 + 89 + 85 = 413 / 5 = 82.6
The impact that the 85 had on the mean test score was that the mean/average increased by 0.6.
Answer:
Step-by-step explanation:
Since this is mathematics, significant figures are not necessary. Thus, we can just take 0.58 and delete the 0s. Now, 
.
72 divided by 9 = 8
8 + 4x4 = 8+16
8+16=24
Answer:
7 Days or X = 7
Step-by-step explanation:
Before we even attempt the problem, we need to craft our equation to work with…
- Multiply 0.09 x 500 = 45
- Now we know what out equation will be which is 45 + 56.37x < $440
- First subtract 45 from $440
- Then devide 45 from 440
- There you go we found the value of x
Final answer:
45 + 56.37(7) = 440
