Hello!

The length and width are given.

We know the formula for calculating perimeter :

\fbox {Perimeter = 2(Length + Width)}

Let's solve!

  • Perimeter = 2(123 + 17k + 24k - 49)
  • Perimeter = 2(41k + 74)
  • \fbox {Perimeter = 82k + 148}

∴ The perimeter is 82k + 148.

Each year farmer records the number of pumpkins he sold for 5 weeks. The mean is 782 and the mean absolute deviation is 52. List
BARSIC [14]

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

What is the mathmatical definition of decomposing
jarptica [38.1K]
It's when we break a number apart. Like as if we take 3,864. And we take each number and put it in a area of the number.

3=Thousands.
8=Hundreds.
6=Tens.
4=Ones.

Fairly simple and easy.
