Answer:
Not probabillity of picking a green marble is 80%
Step-by-step explanation:
Answer:
.80 or 4/5
Step-by-step explanation:
Probability is all about figuring out what you are or not going to get.
One good trick of figuring this out is taking what you don't want, (here its green marbles) take them out, then add all the marbles (G,B,R) and divide. Here you are dividing 8 by 10 which comes out to .80
The only other thing to do is simplify if needed. .80 turns into 8/10 and the only thing that 8 and 10 are divisible by is 2 so it would turn into 4/5
Hope this info can help ;)

If there are two children in the Patel family. They are twins of the same age. Then zero is the range of their ages
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
There are two children in the Patel family.
They are twins of the same age.
Let x be the age of two children.
As they are twins so the age of children's is same.
The formula of range is highest minus lowest.
range = highest - lowest
Range=x - x
Range =0
Hence, the range of their ages is 0.

2 (3x - 5) + 4 = -18
Solve for 20 Points
Answer:
x = -2
Step-by-step explanation:
2(3x - 5) + 4 = -18
Distribute the 2
6x - 10 + 4 = -18
6x - 6 = -18
Add 6 to both sides
6x = -12
Divide both sides by 6
x = -2
Check:
2(3x - 5) + 4 = -18
substitute x = -2 into the original equation
2(3(-2) - 5) + 4 = -18
2(-6 - 5) + 4 = -18
2(-11) + 4 = -18
-22 + 4 = -18
-18 = -18
So x = -2 is true.
Answer:
x=-2
Step-by-step explanation:
2(3x-5)+4=-18
We move all terms to the left:
2(3x-5)+4-(-18)=0
We add all the numbers together, and all the variables
2(3x-5)+22=0
We multiply parentheses
6x-10+22=0
We add all the numbers together, and all the variables
6x+12=0
We move all terms containing x to the left, all other terms to the right
6x=-12
x=-12/6
x=-2

Work out the area of this circle. Take pi to be 3.142 and give your answer to 1 decimal place
Step-by-step explanation:
I think you have forgotten to attach the question.
Anyways....
In order to find the area of a circle use the formula:
π[tex]r^{2}[/tex] Where r is the radius
For example the radius is 3cm. The area of the circle will be:
π × [tex]3^{2}[/tex]
Since you have taken pi as 3.142...
3.142 × [tex]3^{2}[/tex]
3.142 × 9
= 28.278
In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.
= 28.3 [tex]cm^{2}[/tex]

Find the area of a circle in feet with the radius being 3'.
Answer:
28.27 ft²
Step-by-step explanation:
[tex]A=\pi r^2[/tex] where [tex]r[/tex] is the radius
Plug in 3 for the radius
[tex]A=\pi (3)^2\\A=9\pi[/tex]
[tex]A=28.27[/tex] (approximate answer when rounded to the nearest hundredth)
Therefore, the area of the circle is 28.27 ft².
I hope this helps!
Answer:
exact area: 9 ft²
approximate area: 28.3 ft²
Step-by-step explanation:
An area cannot be in feet. It must be in a square unit such as square feet.
A = r²
A = ()(3 ft)²
A = 9 ft²
A = 9(3.14159) ft^2 = 28.3 ft²
Answer:
exact area: 9 ft²
approximate area: 28.3 ft²
