There are 5 pens total; 3 of them red.
first draw probability red: 3/5
second draw probability red: 2/4
On the second draw there is one less red pen and one less total pens because they are not being put back into the pool of pens.
combined probability red then red (without replacement)
= (3/5) * (2/4) = 6/20 = 3/10
Answer:
192
Step-by-step explanation:
multiply 32x6 and you will get your answer
In a function, each x-coordinate can be used only once.
If you have two points, one above the other on the same vertical line, it is not a function.
You are correct.
If the work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb,then the work that is needed to stretch it 18 inches beyond its natural length is 81 ft.lb.
Given that work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb.
We are required to find the work that is needed to stretch 18 inches beyond its natural length.
Multiplication is basically finding out the product of two or more numbers.
Work required to stretch the spring 2 feet beyond its natural length=9 ft. lb.
So, to find the work that is required to stretch the spring 18 feet beyond its natural length, we have to multiply 9 with 9 which will give us 81. So the work required is 81 ft.lb.
Hence if the work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb,then the work that is needed to stretch it 18 inches beyond its natural length is 81 ft.-lb.

Answer:
x=6
Step-by-step explanation:
6(2x -11) 15 =21
6 × 2x = 12x
6 × -11 = -66
12x -66 + 15 = 21
-66 + 15 = -51
12x -51 = 21
-51 + 51 = 0
21 + 51 = 72
12x = 72
12x ÷ 2 = 0
72 ÷ 12 = 6
x = 6
