A bag of marbles contains only yellow, blue and green marbles. There are 4 yellow marbles and 2 blue marbles, and 1/3 of the marbles are green. If a marble is picked out at random, what is the probability it will be blue? Please give an answer ASAP!
Answer:
2/9
Step-by-step explanation:
There are 4 yellow marbles and 2 blue marbles = 6 marbles
This is 2/3 of the marbles since 1/3 are green
2/3 of the total marbles are 6 marbles
2/3 * m = 6
m = 6 * 3/2 = 9
1/3 m = green marbles = 1/3 *9 = 3
4 yellow marbles and 2 blue marbles 3 green marbles = 9 marbles
P ( blue) = blue/total = 2/9

term of the sequence 40,50,60, ....
n starts at 1, and n is a positive whole number (1,2,3,...)
======================================================
Explanation:
The sequence is arithmetic with first term 40 and common difference 10. Meaning we add 10 to each term to get the next one.
--------
a1 = 40 = first term
d = 10 = common difference
[tex]a_n = a_1 + d(n-1)\\\\a_n = 40 + 10(n-1)\\\\a_n = 40 + 10n-10\\\\a_n = 10n + 30\\\\[/tex]
is the general nth term of this arithmetic sequence
Plug in n = 1 and you should get [tex]a_1 = 40[/tex]
Plug in n = 2 and you should get [tex]a_2 = 50[/tex]

Step-by-step explanation:
To be a geometric sequence there must be a common ratio which basically means the number you multiply a term by to get the next one, and the common ratio must be the same between all terms. The only sequence that follows this is the first one.
Answer:
Step-by-step explanation:
Each term of a geometric sequence is a multiple of the previous term. For example, if the first term is 2 and the common ratio is 3, then the next term is 6; the next term is 18. And so on.
1,2,4,8,16.... fits this pattern. The first term is 1 and each succeeding term is 2 times the previous term: 1*2 = 2; 2*2 = 4; 4*2 = 8, and so on.
Which statement is true about the following system of equations?
3x - 1/2y = 1
x + 2y = 7
Select one:
a. y<x
O b.y=x
O c.y>x
d. can not be determined
Answer:
c. y>x
Step-by-step explanation:
When given a system of equations, one of many methods can be used to solve these types of systems. One of these includes substitution which involves solving for one variable that is included in another equation, and putting that equality in place of the variable.
Here is what I mean by this:
Given that 3x - 1/2y = 1, and x + 2y = 7, you can rearrange the x + 2y = 7 to solve for x by isolating it.
x + 2y = 7 → x = 2y - 2y = 7 - 2y [for an equation, what you do to one side, you must do to the other] → x = 7 - 2y.
Now that we have an expression which is equal to x.
We can directly replace that with the 3x in the other equation by multypling this by 3:
x = 7 - 2y → 3(x) - 1/2y = 1
3(7 - 2y) - 1/2y = 1
Now that we only have y's, we can simply the equation, and solve for y.
21 - 6y - 1/2y = 1
21 -13/2y = 1
(get rid of the constant on the left side by subtracting)
-21 -21
-13/2y = -20
(remove the denominator by Multiplying)
×2 ×2
-13y = -40
÷13 ÷13
(cancel out the coefficient by dividing)
-y = -40/13
(take the opposite of the other side to make y positive)
×-1 ×-1
y = 40/13.
Now that we have y just solve for x since we already have a term of x in the other equation:
y = 40/13 → x + 2y = 7
x + 2(40/13) = 7
x + 80/13 = 7
Then subtract both constants to find x:
x + 80/13 - 80/13 = 7 - 80/13
x = 7 - 80/13

what does 10 with a little 4 on the top mean
Answer:
They are called exponents, they multiply the number itself (the bigger number) so the answer to 10 with a little 2, means 10x10 or "100"
Answer:
Using exponents is a short way of saying “multiply the number by itself.” The little number up above tells you how many times to multiply the number by itself. So 10 2 means 10 x 10, or 100. ... (Each time you have an exponent of 10, the little number up above tells you how many zeros there will be in the answer).

given f(x) = 3/2x - 5 and g(x) = x^2 + 2x solve for g(-2)
Answer:
g(-2) = 0
Step-by-step explanation:
Since it is asking for g(-2), that means that we only have to worry about the equation g(x) = x^2+2x. When it asks for g(-2), that means you replace every "x" that shows up in the equation with -2.
So plugging in -2 for x we get g(-2)=(-2)^2+2(-2). Simplifying we get g(-2)=4+(-4). Now adding we finally get g(-2)=0

Using coordinates of the labeled points to find a point slope equation of the line
Answer:
y +4= -3 ( x-3)
Step-by-step explanation:
The point slope form of a line is
y-y1 = m(x-x1)
The point requested is (3,-4)
y - -4= m ( x-3)
y +4= m ( x-3)
The slope of the line is positive since it goes from the top left to the bottom right
The slope can be found from (0,5) and (3,-4)
m = (y2-y1)/(x2-x1)
= (5 - -4)/(0-3)
= (5+4)/(0-3)
= 9/-3
= -3
y +4= -3 ( x-3)
The slope in all answer choices is 3 or -3.
Since the line is going down, the slope is going to be negative (-3).
Point slope form: y - y1 = m(x - x2)
We are given a point in the question so use it to fill in the equation.
y + 4 = -3(x - 3)

Match the pairs of variables with the type of relationship they show. the number of high school seniors and high school graduates the amount of snowfall and the number of voters the number of doctors and the number of nurses correlation without causation correlation with causation
Answer: Correlation without causation.
Correlation with causation: the number of high school seniors and high school graduates
Step-by-step explanation:
Correlation is a term that tells there is a relationship between two quantities.
Causation is a relationship where one quantity is affected by the other.
The number of graduates completely depends on the number of high school seniors.
So, the relationship between the number of high school seniors and high school graduates is a causation.
There is no relation between the amount of snowfall and the number of voters.
The number of nurses depends on the number of doctors but not completely.
It may be possible that the number of nurses will not increase with an increase in the number of doctors in a particular hospital.
So, there is a correlation without causation between the number of doctors and the number of nurses.
Answer:
correlation without causation is the number of doctors
and the number of nurses
correlation with causation is the number of high school seniors
and high school graduates

A theater offered pre-sale tickets two days before a showing. On the first day, 12
adult and 5 children's tickets were purchased for $114.50. On the second day, 24
adult and 8 children's tickets were purchased for $218. Find the price of an adult
ticket and a children's ticket.
Answer:
Adult ticket: $7.25
Children's ticket: $5.50
Step-by-step explanation:
Set up a system of equations where a represents the cost of an adult ticket and c represents the cost of a child's ticket:
12a + 5c = 114.5
24a + 8c = 218
Solve by elimination by multiplying the top equation by -2:
-24a - 10c = -229
24a + 8c = 218
Add them together:
-2c = -11
c = 5.5
Now, plug in 5.5 as c in an equation to find a:
12a + 5c = 114.5
12a +5(5.5) = 114.5
12a + 27.5 = 114.5
12a = 87
a = 7.25
Answer:
Adult Ticket is $7.25 and Child Ticket is $5.50
Step-by-step explanation:
Lets make 2 equations out of the given information.
a = adults
c = children
Equation 1: 12a + 5c = 114.5
Equation 2: 24a + 8c = 218
We can now multiple Equation 1 by 2 so that we are able to eliminate the value of a.
New Equation 1: 24a + 10c = 229
Equation 2: 24a + 8c = 218
Now we can use subtraction and get a new equation: 2c = 11
Then divide and get: c = 5.5
The cost for a child's or "children's" ticket is $5.50 each. We can fill in the value of the childs ticket and get the value of an adult's ticket as $7.25.
Therefore, Children's Ticket costs: $5.50 & Adult's Ticket costs: $7.25
PLEASE HELP!!!!!! the sum of a number times 10 and 15 is at most -17

10x <= -32
Divide both sides by 10:
X <= -32/10
Simplify:
X <= -16/5 as a fraction or -3.2 as a decimal
