Answer:

Event 4: 0/16 (no blue marbles in any of the bags) Event 2: 9/20 (black only) Event 3: 1/2 (for both) Event 1: 20/20 (black or green)

Step-by-step explanation:

2 bags have green and black.

A has 16 in total.

8 of each.

B has 20 in total.

9 black.  11 green.

%~LEAST LIKELY~%

Event 1: Absolute

It's talking about both marbles, so it doesn't matter which one you get, as long as you pick one of the two from the bag.

Event 2: Less likely

9/20 for only black versus 11/20 for only green.

Event 3: As likely as not

Both have the probability of 8/16 which simplifies to 1/2.

Event 4: Never

No blue marbles.

The area of the isosceles triangle is 80 square centimeters. Use the equation 1/2(8h) =80 to find the height of the triangle.
Dmitry [639]

Answer:

20cm

Step-by-step explanation:

Given data

Area=  80cm^2

we know that the expression for the area of a triangle is

A= 1/2B*H

from the given expression 1/2(8h) =80 the base is 8cm

let us substitute to find the height h

1/2(8h) =80

4h=80

h= 80/4

h= 20cm

Hence the heigth h is 20cm

Jessica and Josh are selling Entertainment Books to raise money for the art room at their school. Jessica received the prize for
Over [174]

Answer:

Josh sold 16 books and Jessica sold 240 books

Step-by-step explanation:

Given: Jessica sold 15 times more books than Josh.

           Together they sold 256 books

To Find : How many did each one of them sell?

Solution:

Let Jessica sold x books

Let Josh sold y books.

Since we are given that Jessica sold 15 times more books than Josh.

⇒x=15y --a

We are also given that  Together they sold 256 books.

⇒x+y=256 --b

Using substitution method

Put value of x from equation a in equation b

⇒15y+y=256

⇒16y=256

⇒y=\frac{256}{16}

⇒y=16

Thus Josh sold 16 books

Jessica sold books = 15y = 15*16=240

Hence  Josh sold 16 books and Jessica sold 240 books
