There are 3 counters in a bag. One counter is red. One counter is green. One counter is blue. Mike takes at random a counter from the bag. He puts the counter back in the bag. Then Ellie takes at random a counter from the bag. The possible combinations are: RR, RG, RB, GR, GG, GB, BR, BG, BB. Find the probability that Mike takes a blue counter and then Ellie takes a green counter.
Answer:
[tex]\frac{1}{9}[/tex] or 11.11%
Step-by-step explanation:
P(A) = probability of an event
f = favored outcomes
N = number of total outcomes
[tex]P(A)=\frac{f}{N}[/tex]
In this equation there is one favored income, when the first counter is blue and the second one is green. There are also nine total outcomes. This means that the equation necessary is:
[tex]P(A)=\frac{1}{9}[/tex]
The probability that Mike takes a blue counter and then Ellie takes a green counter is [tex]\frac{1}{9}[/tex] or around 11.11%

Tell whether the point (-10,10) is on the graph of f(x) = |x|. If it is, give the coordinates of another point with the same y-value.
The coordinates of another point with the same y-value are (10, 10).
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
f(x) = |x|
For (-10, 10)
i.e,
x = -10
f(-10) = |-10| = 10
So,
(-10, 10) is on the graph.
Now,
For x = 10,
f(10) = |10| = 10
This means,
(10, 10) is also on the graph.

for each job. Express the relationship between time spent on a job and the
fee charged to the client.
a Express the relation using function notation
Let's call the number of hours spent on a job as "h". Then, the fee charged to the client can be represented as a function of "h" as follows:
f(h) = 30h + 40
This means that for any value of "h" (representing the number of hours spent on a job), the function f(h) gives the corresponding fee charged to the client.
What is a function notation?Function notation is a mathematical notation used to express a mathematical function, which assigns a unique output to each input of a set. The function is represented by a symbol, usually a letter (such as f or g), followed by a variable in parentheses.
For example, the function f(x) = x^2 assigns the value x^2 to the input x. The input is usually referred to as the argument of the function. The function notation is commonly used in calculus, algebra, and other branches of mathematics.

The science of statistics is concerned with the research and advancement of methods for collecting, analyzing, interpreting, and presenting empirical data. The science of learning from data is called statistics, which is also possibly an art. The discipline's focus is on the gathering, analyzing, and interpretation of data as well as the efficient dissemination and presentation of findings that rely on data.
We can assume the following:
1). There are 13-8=5 pupils who study physics and math together but not statistics (green colour)

a landscaper wants to place a stone walkway from one corner of the rectangular lawn to the opposite corner. what will be the length of the walkway? round to the nearest inch. feet
The length of the stone walkway would be 536.64 inches.
To find the length of the stone walkway, the landscaper needs to determine the length of the diagonal of the rectangular lawn.
The length of the diagonal can be calculated using the Pythagorean theorem:
[tex]d^2 = l^2 + w^2[/tex]
Where d is the length of the diagonal, l is the length of the rectangle, and w is the width of the rectangle.
So to find the length of the walkway, the landscaper would need to know the length and width of the rectangular lawn.
Suppose a landscaper wants to place a stone walkway from one corner of a rectangular lawn that is 40 feet long and 20 feet wide to the opposite corner.
Using the Pythagorean theorem, we can calculate the length of the diagonal:
[tex]d^2 = 40^2 + 20^2[/tex]
[tex]d^2 = 1600 + 400[/tex]
[tex]d^2 = 2000[/tex]

Solve for y
3y - 2 = 10 - 3x
The equation solved for the variable y is:
y = 4 - x
How to solve for y?
To do this, we need to isolate the variable y in the given equation.
We have the equation:
3y -2 = 10 - 3x
Adding 2 in both sides we will get:
3y -2 +2 = 10 - 3x + 2
3y = 12 - 3x
Now we can divide both sides by 3 to get:
3y/3 = (12 - 3x)/3
y = 4 - x
That is the equation solved for y.

the sum of two sumbers is 3 more than four times the firsst number. their difference is 10 less than twice the second number. find each of the numbers
The two numbers are 7/6 and 5 when the sum of two numbers is 3 more than four times the first number.
Let's call the two numbers x and y, where x is the first number and y is the second number.
The problem gives us two equations that relate the two numbers:
[tex]x + y = 3 + 4x\\y - x = 2y - 10[/tex]
We can substitute the expression for y from equation 1 into equation 2:
[tex]y - x = 2(3 + 4x) - 10[/tex]
Expanding the right side and simplifying, we get:
[tex]y - x = 6 + 8x - 10\\y - x = 8x - 4[/tex]
Adding x to both sides:
[tex]y = 9x - 4[/tex]
Substituting this expression for y into equation 1:
[tex]x + (9x - 4) = 3 + 4x[/tex]
Expanding and simplifying the right side:
[tex]10x - 4 = 3 + 4x[/tex]
Subtracting 4x from both sides:
[tex]6x - 4 = 3[/tex]
Adding 4 to both sides:
[tex]6x = 7[/tex]
Dividing both sides by 6:
[tex]x = 7/6[/tex]
Substituting this value of x back into the expression for y:
[tex]y = 9x - 4 = 9 * (7/6) - 4 = 63/6 - 4 = 9 - 4 = 5[/tex]

math and verbal sat scores are each distributed normally with n(500,10000) what fraction of students scores above 700? above 550? between 400 and 550? below 400? below 550?
Above 700: 5%, Above 550: 34%, Between 400 and 550: 26%, Below 400: 16%, Below 550: 55%.
To calculate the fraction of students who scored above 700, we can use the z-score formula, which is (x - μ) / σ, where x is the score, μ is the mean, and σ is the standard deviation. In this case, μ = 500 and σ = 100. Plugging in 700 for x, we get (700 - 500) / 100 = 2. This corresponds to a z-score of 2, which is .9772, meaning that 97.72% of the scores are below 700. This means that 5% are above 700. To calculate the fraction of students who scored above 550, we can use the same formula, but with 550 for x. This gives us (550 - 500) / 100 = .5, which corresponds to a z-score of .5, meaning that 84% of the scores are below 550. This means that 34% are above 550. To calculate the fraction of students who scored between 400 and 550, we can subtract the z-score of 400 from that of 550. This gives us .84 - .2 = .64, meaning that 64% of the scores are below 550. This means that 26% are between 400 and 550.

The equation for the Bowler world is c = $1.1g + $5,
The equation for the Lucky spares is c = $1.5g + $3.
and the cost is the same for 5 games and the cost is $10.5.
What is a linear equation?Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.
Both linear equations with one variable and those with two variables exist.
Given the Bowler, World charges $5.00 to rent shoes and $1.10 per game. Lucky Spares charges $3.00 for shoes and $1.50 per game.
Part A
using g for the number of games and c for the cost
for Bowler World
charges for shoes = $5
cost for per game = $1.1
cost for g games = $1.1g
total cost c = $1.1g + $5 ..........(1)
for Lucky spares
charges for shoes = $3
cost for per game = $1.5
cost for g games = $1.5g
total cost c = $1.5g + $3 ..........(2)
B. if the cost used in both places is equal then equation 1 equals equation 2
so $1.1g + $5 = $1.5g + $3
1.5g - 1.1g = 5 - 3
0.4g = 2
g = 2/0.4
g = 5
and cost is c = $1.1g + $5
c = 1.1*5 + 5
c = 5.5 + 5
c = $10.5
Hence equations are c = $1.1g + $5 and c = $1.5g + $3,
and the cost is same for 5 games and the cost is $10.5.
