The two numbers would be 12 and 8 because 12 is 4 more than 8 and so the sum of 12 and 8 is 20.
Answer:
Matthew payed .63 (rounded .625) cents for each toothbrush while Jon payed .72 cents per toothbrush
Step-by-step explanation:
$5 = 8 toothbrushes
$18 = 25 toothbrushes
5 / 8 = .625
18/25 = .72
The +2 is a reminder to add when he multiply 4*1 (4*1=4+2=6)
4*2=8
4*5=20 (so he writes the 0 with a remainder of 2)
4*1=4+2=6
so,
152x4= 608
Answer:
86.7%
Step-by-step explanation:
For questions regarding values related to a normal distribution, a suitable calculator is required. Numerous calculators, apps, web sites, and spreadsheets are capable of answering this question.
__
One standard deviation above the mean is 327 +27 = 354, so the value is expected to be slightly more than 50% +34% = 84%. It is no surprise, then, that a calculator tells you 86.7% of the data is below 857.
_____
<em>Additional comment</em>
The "empirical rule" tells you 68% of the area is within 1 standard deviation of the mean. The distribution is symmetrical, so half that, 34%, is between the mean and 1 standard deviation above the mean. Of course, 50% of the data is below the mean.
