anastassius [24]3 years ago
6 0

Answer:

21.6

Step-by-step explanation:

To solve for expressions with variables, substitute the variable's value is where the variable is in the expression.

The variable is y, and y's value is 0.3

Substitute y for 0.3

8(y+2.4)

= 8(0.3+2.4)

Now solve by following BEDMAS (brackets, exponents, division, multiplication, addition, subtraction).

= 8(0.3+2.4)      <=Solve the brackets by adding

= 8(2.7)    <= multiply

= 21.6

Answer:

MAD = 2

Step-by-step explanation:

<u><em>First We'll find the mean of data</em></u>

Mean = \frac{20}{5}

Mean = 4

<u><em>Then, we'll find absolute deviation</em></u>

=> |4-3| = 1

=> |4-2| = 2

=> |4-1| = 3

=> |4-1| = 3

=> |4-3| = 1

<em><u>Now, taking the mean of these absolute deviations:</u></em>

MAD = \frac{1+3+3+2+1}{5}

MAD = \frac{10}{5}

MAD = 2

Find the perimeter of a regular octagon if one of its sides is x + 6 and another side is 14 – x.
chubhunter [2.5K]

Answer:

  80 units

Step-by-step explanation:

The sides of a regular octagon are all the same length.

  x +6 = 14 -x

  2x = 8 . . . . . . add x-6

  x = 4

  x+6 = 10 . . . . the length of each of the 8 sides

P = 8s = 8(10) = 80

The perimeter of the octagon is 80 units.

How will a high outlier in a data set affect the mean and median?
RUDIKE [14]

Answer:

B. distribution skewed to the right, mean pulled to the right, median not effected

Step-by-step explanation:

When a distribution is skewed to the right, it means that the data is positively skewed or has more positive numbers than negative numbers.

An outlier can affect the mean of a distribution since a high value outlier will make the mean be much higher than the median. In this case, since the distribution is positively skewed, a high outlier will pull the mean to the right (to higher positive values).
