Answer:

Probability[First marble blue, second is green without replacement] = 1/12

Step-by-step explanation:

Given:

Number of green marble = 3

Number of red marble = 4

Number of blue marble = 2

Total marble = 9 marble

Find:

Probability[First marble blue, second is green without replacement]

Computation:

Probability of an event = Number of favorable outcome / Number of total outcome

Probability[First marble blue] = 2 / 9

Probability[second is green] = 3 / [9-1]

Probability[second is green] = 3 / 8

Probability[First marble blue, second is green without replacement] = Probability[First marble blue] x Probability[second is green]

Probability[First marble blue, second is green without replacement] = [2/9][3/8]

Probability[First marble blue, second is green without replacement] = 6 / 72

Probability[First marble blue, second is green without replacement] = 1/12

The required arrow shows the outliner of the spread. Option C is correct.

A scatter plot is a collection of points plotted on two axes, horizontal and vertical. Scatter plots are useful in statistics because they illustrate the extent, if any, of correlation between the values of observed quantities or phenomena (called variables).

here,

Since a figure is given, of a scatter plot where the value is distributed from 12 to 24, and the density of the graph at 12 to 14 is more than the rest of the plot and the red arrow marked, the value lies outside the spread and the value is said outliner.

Thus, the required arrow shows the outliner of the spread.

Answer:

Let x=number of $0.25 increases, so the equation for revenue=price*number of tickets or people) becomes

Revenue=($3.00+$0.25x)(400-20x)

where ($3.00+$0.25x) :increase in price

and

(400-10x) : decrease in number of people

Expanding Revenue

Revenue[R]=1200-60x+100x-5x²:1200+40x-5x²

Taking the derivative of R and set it equal to 0:

R'=0+40-10x=40-10x

we have

R'=0

40-10x=0

x=40/10

x=4

So the ticket price is $3.00+$0.25*4=$4

The number of people will attend is 400-20*4=$320

At $320 ticket price will the revenue be maximized.

Step-by-step explanation:

A $320 ticket price will the revenue be maximized

Answer:

1. 180

2. 52

3. 288

Step-by-step explanation:

The area of a rectangle can be found by multiplying the length by the width, so the area of the rectangle is 15 * 12 = 180. The area of a triangle can be found by multiplying the base by the height and divide by 2, so the area of the triangle is [tex]13*\frac{8}{2} = 13 * 4 = 52[/tex]. The area of a parallelogram can be found by multiplying the length and the height, so the area of the parallelogram is 24 * 12 = 288.
