Cameron has a bag that contains one silver (S) and one gold (G) marble. The marbles are the same size. Cameron chooses one marble at random and then puts it back in the bag. Then he chooses a second marble. The outcome "GS" means that a gold marble was chosen first and a silver marble was chosen second.
Answer:
(SS,SG,GS,GG) Probability 0.25
Step-by-step explanation:
i don't know how to do this
Heyo!
So, first things first:
Based on the data shown, it appears that Cameron has 1/4 a chance to really recieve any combo of the following. Hence, he can get SS, SG, 6S, GG. So, each chance he picks, he has a 0.25 chance of probably recieving any of the combo. So, the outcome order is (SS, SG, GS, GG) and the probability for each is 0.25.
It hard to really describe how to write it out without an image, but I hope this helps! Pls, lmk if it does! Good luck!

Answer:
Astronomers were trying to find the weight of six planets - Mars, Venus, Pluto, Jupiter, Mercury and Saturn. The number of planets lighter than Mars was equal to the number of planets heavier than Venus. Saturn was heavier than Mars and Mercury was heavier than Pluto. Venus was lighter than Mars. Saturn was not the heaviest planet.

For what values of x is the equation X^2-x=20 true?
Answer: x = 5 or x = -4
Step-by-step explanation:
Given equation
x² - x = 20
Subtract 20 on both sides
x² - x - 20 = 0
Cross factorize the equation
x -5
x 4
Factorize the equation
(x - 5) (x + 4) = 0
[tex]\boxed{x=5}[/tex] or [tex]\boxed{x=-4}[/tex]

Answer:
B. 2³(3 x 5² + 2²)
Step-by-step explanation:
2³(3 x 5² + 2²)
Step 1. Simplify the exponents
8(3 x 25 + 4)
Step 2. Multiply 3 and 25
8(75 + 4)
Step 3. Add 75 and 4

Answer:
Option B. 2³(3 x 5² + 2²) is correct
Step-by-step explanation:
2³(3 x 5² + 2²)
First of all multiply the exponents
8×(3×25+4)
Then do the multiplication of 3 and 25
8×(75+4)
Now add the following numbers in the bracket
8×(79)
And the last multiply the following numbers
8×79
632
[Hence, the expression 2³(3 x 5² + 2²) is equal to 632. ]

what is the equation of the line parallel to y=1/2x+1 that contains the point (-2,1)
Answer:
y = 1/2x + 2Step-by-step explanation:
The line parallel to the given has the same slope:
y = 1/2x + bUse the given point to find the y-intercept:
1 = 1/2(-2) + b1 = -1 + bb = 1 + 1b = 2The line is:
y = 1/2x + 2Find the equation of this line. y= [?]x+[?]
Answer:
[tex]y=3x-4[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0)
1) Determine the slope (m)
[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
On the graph, two points are highlighted for us: (0,-4) and (2,2). Plug these into the formula:
[tex]m=\displaystyle\frac{2-(-4)}{2-0}\\\\m=\displaystyle\frac{2+4}{2}\\\\m=\displaystyle\frac{6}{2}\\\\m=3[/tex]
Therefore, the slope of the line is 3. Plug this into [tex]y=mx+b[/tex]:
[tex]y=3x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=3x+b[/tex]
Recall that the y-intercept occurs when x=0. Given the point (0,-4), the y-intercept is therefore -4. Plug this into [tex]y=3x+b[/tex]:
[tex]y=3x+(-4)\\y=3x-4[/tex]
I hope this helps!

The Piersons have paid $75 to enroll their son Fred at preschool. They will pay $152 a month in fees. Write and solve an equation to work out how many months it will take for the total bill to reach $683.
Answer: 4 months
Step-by-step explanation:
$75 + $152X = 683
That's the equation you need to set up, with X being the number of months.
To solve, first subtract 75 from both sides.
$152x = 608
Then, divide each side by 152
X = 4
The answer is 4 months.

Three liquids are to be mixed in the ratio of 5:3:1 . If ten liters is to be produced, how much of each of the ingredients should be used ?
Answer:
4,320
Step-by-step explanation:
One gallon = 15,140 drips
One liter = 4,000 drips
The ingredients that should be used will be ( 50 / 9 ), ( 5 / 3 ), and ( 10 / 9 ).
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that three liquids are to be mixed in the ratio of 5:3:1.and their total is ten liters. The quantity of each part will be calculated as:-
Let the ratio is L₁ = 5x, L₂ = 3x and L₃ = x.
5x + 3x + x = 10
9x = 10
x = 10 / 9
The fraction of each part will be calculated as:-
5x = 5 x { 10 / 9 ) = 50 / 9
3x = 3 x ( 10 / 9 ) = 10 / 3
x = 10 / 9
Therefore, the ingredients that should be used will be ( 50 / 9 ), ( 5 / 3 ), and ( 10 / 9 ).

When 512 is divided by 313 using repeated subtraction, the quotient is 1. The answer in mixed form is [tex]1\frac{199}{313}[/tex].
What is repeated subtraction?Repeated Subtraction is a method that subtracts the equal number of items from a group, also known as division. Using this method, the same number is subtracted repeatedly from another larger number until the remainder is zero, or smaller than the number being subtracted.
Dividend = 512
Divisor = 313
Subtract 313 from 512 repeatedly.
512 - 313 = 199
Here, 313 is subtracted once from 512 with remainder as 199.
Hence, the quotient = 1, remainder = 199.
Answer in mixed fraction:
[tex]\frac{Dividend}{Divisor} =Quotient \frac{Remainder}{Divisor} = 1\frac{199}{313}[/tex]
