erica [24]3 years ago

Answer:

5.6

Step-by-step explanation:

Sheryl got the following scores on her spelling tests.

95, 89, 99, 85, 82

Mean = sum of all observations/ Number of observations

Sum of all observations =95+89+99+85+82=450

Number of observations = 5

So,

Mean =\frac{450}{5}=90

Let M denotes the mean

Mean absolute deviation =\frac{\sum_{i=1}^{n}\left | x_i-M \right |}{n}

Put n=5

So,

Mean absolute deviation =\frac{\sum_{i=1}^{5}\left | x_i-M \right |}{5}=\frac{|95-90|+|89-90|+|99-90|+|85-90|+|82-90|}{5}=\frac{5+1+9+5+8}{5} =\frac{28}{5}=5.6

Equations and inequalities!<br> solve for w <br> 11=253-w
Annette [7]

Answer:

w = 242

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

  • 11=-w + 253
  • -w + 253 = 11

Step 2: Subtract 253 from both sides.

  • -w + 253 - 253 = 11 - 253
  • -w = -242

Step 3: Divide both sides by -1.

  • \frac{-w}{-1}=\frac{-242}{-1}
  • w = 242

Step 4: Check if solution is correct.

  • 11 = 253 - (242)
  • 11 = 253 - 242
  • 11 = 11

Therefore, w = 242.

Have a lovely rest of your day/night.
