Step-by-step explanation:

First, we get the mean and median of the first data set WITH 5 years : mean = 15 median = 14, then remove the 5 years mean = 15.222 median = 14

Answer:

The mean will increase but the median will remain the same.

Step-by-step explanation:

With the 5 years:

Mean = 15

Median = 14

Without the 5 years:

Mean = 15.222222222222

Median = 14

Can someone solve this please?

Answer:

3.16 units

Step-by-step explanation:

The distance between the points P1 (6, 8) and P2 (7, 5)) can be solved by using the distance formula given as $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ .

Let,

$(6, 8) = (x_1, y_1)$

$(7, 5) = (x_2, y_2)$

Plug these values into the distance formula.

Thus:

$d = \sqrt{(7 - 6)^2 + (5 - 8)^2}$

$d = \sqrt{(1)^2 + (-3)^2}$

$d = \sqrt{1 + 9}$

$d = \sqrt{10} =$

d = 3.16 (nearest tenth)

Distance between the two points in the graph is approximately 3.16 units

The number of purses a vendor sells daily has the probability distribution represented in the table. Number of Purses, x 0 1 2 3

Arada [10]

Answer:

(D)$81

Step-by-step explanation:

Given that the number of purses a vendor sells daily has the probability distribution represented in the table.

Expected Value, $E(x)=\sum_{i=1}^{n}x\cdot p(x)$

Therefore:

$E(x)=(0X0.35)+(1X0.15)+(2X0.2)+(3X0.2)+(4X0.03)+(5X0.07)\\=0+0.15+0.4+0.6+0.12+0.35\\E(x)=1.62$

If each purse sells for $50.00, the number of expected daily total dollar amount taken in by the vendor from the sale of purses

=Expected Value X $50

=1.62 X $50

=$81

The correct option is D.
