Answer:

1). Mean: 14.2

Median: 13.5

Step-by-step explanation:

To calculate the mean, sum all values and divide by the number of values:

(13+16+14+17+13+12) / 6 ≈ 14.2

To calculate the median, order the values from small to large and take the middle value. If there is no middle. average the two values in the middle:

12,13,13,14,16,17

The median is (13+14)/2 = 13.5.

Using this explanation you should be able to find the rest.

Find the areas of the trapezoids. PLZ HELP!!!!

barxatty [35]

Answer:

Type 7.5 in the box!

Step-by-step explanation:

Consider the trapezoid formula ( ( base 1 + base 2 ) / 2 ) * height;

$Length of Base 1 - 1 unit,\\\\Length of Base 2 - 4 units,\\\\Length of Height - 3 units ( length of x - intercept in shaded region )\\\\Area of Trapezoid = ( Average of Bases ) * Height = ( ( 1 + 4 ) / 2 ) * 3 = ( 5 / 2 ) * 3 = 7.5 square units,\\\\Solution; 7.5 square units$

Area = 7.5 square units

S=k/v(s)+1/v(s) in terms of v(s)

otez555 [7]

Answer:

k + 1

v(s) = -------------

Step-by-step explanation:

Solve the equation S=k/v(s)+1/v(s) for v(s).

To do this, combine the two terms on the right side, which is easily possible becuse they have the same denominator: v(s):

k + 1

S = ------------

v(s)

Now interchange S and v(s), obtaining:

k + 1

v(s) = -------------
