Answer:
When we have a mean M and a standard deviation S, the values that are within the mean absolute deviation are all the values in the interval:
[M -S, M + S]
In this case, we have:
M = 782
S = 52
Then the interval is:
[782 - 52, 782 + 52]
[730, 834]
Then any number between 730 and 834 are possible answers to this question, for example, we can choose:
789 and 801
Answer:
116
Step-by-step explanation:
82 brownies sold for $1 each is $82 in total
140-82=58
each cookie is sold at $0.5 so we need to multiply the rest of the cash by 2
58×2=116
so he needs to sell 116 more cookies to reach his goal
Answer:
0
Step-by-step explanation:
-20.5 is the same as -20.5
, since anything to the zero power is equal to 1.
Answer:
The 3 numbers must be multiples of 3, 4, and 5
Step-by-step explanation:
Pythagorean Triples are numbers that you know will come out perfectly in the Pythagorean Theorem. But the easiest way to explain this is to show you an example.
Say you're given the numbers 12, 16, and 20.
They should be able to be divided by the same number and equal 3, 4, and 5.
In this case, the number is 4.
12/4=3
16/4=4
20/4=5
So, this is a 3-4-5 triangle, or a Pythagorean Triple.
