A bag contains five red marbles, two orange marbles, one yellow marble, and two green marbles. Two marbles are drawn from the bag. What is the approximate probability one of the chosen marbles is orange and one of the chosen marbles is green? 0.02222 0.04444 0.08889 0.13333
Answer:B .04444
Step-by-step explanation: Edg
The probability of drawing an orange and a green marble is P = 0.08889
How to find the probability?Let's assume that the first marble drawn is orange.
The probability of drawing an orange marble is equal to the quotient between the number of orange marbles and the total number of marbles on the bag, so the probability for this first event is:
p = 2/(5 + 2 + 1 + 2) = 2/10 = 1/5
Then we need to draw a green one, but notice that we already drew a marble, so now the total number of marbles is 9, then the probability will be:
q = 2/9
The joint probability is the product of these two, and we also need to add a factor of 2, because we also need to take in consideration the case where the first marble is green and the second is orange, then we will get:
P = 2*(1/5)*(2/9) = 0.08889
We can see that the correct option is the third one.

On the scale drawing of a car, the length from bumper to bumper is 6 inches. The car’s actual length, from bumper to bumper, is 16 feet. Make a ratio table of equivalent ratios to represent this ratio relationship. Your ratio table must show at least four different ratios. Include a copy of the ratio table in your answer.
Answer: 6/192, 1/32, 2/64, 3/96, etc.
Step-by-step explanation:
The scale drawing says that the length is 6 inches, and the actual length is 16 feet. First, we need to get both values into the same unit. 16 feet is 192 inches. So our base ratio is 6/192, or 1/32. Equivalent Ratios include 2/64 and 3/96. :)

..................
The two numbers are,
⇒ p = 13 and q = 2
What are Prime numbers?
Prime number is a whole number greater than 1 whose only factors are 1 and itself.
Here, p and q are both prime numbers and each less than 22.
Now, Both number p and q are prime numbers.
Let p = 13 and q = 2
Clearly, The number 13 and 2 both are prime numbers and less than 22.
Hence, p + q = 13 + 2 = 15
Since, 15 is an odd number but not prime.
So, The two numbers are,
p = 13 and q = 2

3.12
Step-by-step explanation:
if you are in an algebra class write the let statements x = number of pendants
25x = 78 (divide by 25 on both sides)
x = 3.12
if you are not in an algebra class then just divide 78 by 25

Solve the equation f/2 +9=4 how can you isolate the variable F 
Answer:
F= -2.5
Step-by-step explanation:
divide both sides by two in order to isolate f.
by dividing by 2 on the left hand side it cancels out the /2 leaving you with only f
then because you divided the left hand side by 2 you need to do the same on the right therefore giving you -5/2 which equals -2.5
The value of f in the equation is -10.
What is a Variable?'In mathematics, a variable is a symbol and placeholder for a quantity that may change. In particular, a variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set.'
According to the given problem,
First we need to isolate the variable f:
⇒ [tex]\frac{f}{2}+ 9 = 4[/tex]
Now, transposing 9 to the right hand side,
⇒ [tex]\frac{f}{2}[/tex] = 4 - 9
⇒ [tex]\frac{f}{2} = -5[/tex]
⇒ f= ( -5 * 2 )
⇒ f= -10
Hence, the required value of the variable f is -10.

In a geometric sequence, g(3) = 1 and g(8) = 32. Which recursive definition produces this geometric sequence?
Step-by-step explanation:
a geometric sequence means every new element is created by multiplying the previous element always with the same number.
a n = a n-1 * number
a n = a1 * number^(n-1)
=> a8 (or g(8)) / a3 (or g(3)) = number^5 (5=8-3)
=> 32/1 = number^5
=>
[tex]number = \sqrt[5]{32} [/tex]
number = 2
and what is the starting a1 ?
it must satisfy e.g. a3
1 = a1 * 2^2
=> a1 = 1/4
therefore, the requested definition looks like
g(1) = 1/4
g(n) = g(n-1) * 2

Write the slope-intercept form of the equation of each line given the slope and y-intercept.
Slope= -10/3, y- intercept=5
Answer:
y = -10/3x + 5
Step-by-step explanation:
Hi there!
We are given that a line has a slope of -10/3, and a y intercept of 5
We want to write the equation of this same line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
As we are already given the slope and y intercept, we can simply substitute these values into the format for slope-intercept form to find the equation of the line!
Starting with the slope, substitute -10/3 as m in y=mx+b
y = -10/3x + b
Now for the y intercept, substitute 5 as b in the equation
y = -10/3x + 5

In a function the x value cannot repeat
As long as no x value repeats it is considered a function
In answer choice A the x value "1" repeats therefore table a is not a function
In answer choice B no x value repeats twice. This one might be the answer however lets check the other tables just to be safe.
In answer choice C the x value "-4" repeats multiple times therefore table C is not a function
In answer choice D the x value "1" and "2" repeat therefore table D is not a function.
