So Mean Absolute Deviation or MAD for short is the Mean of how far each digit is from the Mean. So first find the mean, then for each number so let's say the mean is 3 and the numbers are 2, 4, 3. So 3-2=1, 4-3=1, 3-3=0. So you have 1, 1, 0. Find the mean of that 1+1+0=2/3 so the MAD is 2/3.

So just follow my steps
1. Find the mean
2. Find the difference from the mean of each number
3. Find the mean of step 2
4. Step 3 is your answer

Solve for the missing length

Fofino [41]

Answer:

2 * sqrt(13)

Step-by-step explanation:

Use pythagoras' theorem.

4^2 + 6^2 = x^2 = 16 + 36 = 52 = 4*13

x = sqrt(4*13)=2 * sqrt(13)

Two less than three times a number is the same as six more than twice the number. Write an equation and solve to find the number

lapo4ka [179]

Answer: 8

Step-by-step explanation:

Let the number be represented by x.

Two less than three times a number is the same as six more than twice the number. This will be:

(3 × x) - 2 = (2 × x) + 6

3x - 2 = 2x + 6

Collect like terms.

3x - 2x = 6 + 2

x = 8.

The number is 8

How can you use 4s fact to find 7x8? Give the product in your explanation.

Mkey [24]

So 4's facts

we know that 4 times 2=8 and the associative property of multiplication says
a(bc)=(ab)c

so 7(8) (means 7 times 8) means 7((4)(2)) and associative say we can group them and say (7)(4)(2) so (4)((7)(2)) or 4(14) and 4 times 14=56

7 times 8=56
