The probability of getting one marble of each color will be 0.044.
What is probability?The probability of an event is a figure that represents how probable it is that the event will take place. In terms of percentage notation, it is stated as a number between 0 and 1, or between 0% and 100%. The higher the probability, the more probable it is that the event will take place. A random event's recurrence is the subject of this area of mathematics. The range of the number is 0 to 1. The degree to which something is likely to happen is essentially what probability means. You will discover the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution.

Help me find the slope of the line and it’s ok if you don’t know all of them
Slope of each graph are [tex]\frac{6}{5}[/tex],[tex]\frac{-1}{3}[/tex] and 1 respectively.
What is a Slope?Slope of a line in mathematics is defined as the ratio of the change in the y coordinate w.r.t the change in the x coordinate.
Both the change in the y-coordinate and the net change in the x-coordinate are denoted by y₂-y₁ and x₂-x₁, respectively.
Thus, the formula for the change in y-coordinate with regard to the change in x-coordinate is
m=y₂-y₁/ x₂-x₁
In the figure 1Taking two points as per observation
Point1: (x₁ y₁)=(0,-3)
Point2:(x₂, y₂)=(5/2,0)
Slope of line=y₂-y₁/ x₂-x₁

There are 80 people in a choir.
Half the people in the choir are women.
The number of men in the choir is one quarter of the number of women.
The rest of the people in the choir are children.
the number of children in the choir: the number of men in the choir = n: 1
Work out the value of n.
You must show how you get your answer.
Answer:
3
Step-by-step explanation:
Number of people in the choir = 80
Number of women = half of 80 = 40
Number of men in the choir is ¼ of the women = 40/4 = 10
Number of men plus women = 10 +40 = 50
Number of children = 80 - 50 = 30
Ratio of children to men = n:1 = 30:10
Divide both sides by 10
30:10 = 3:1
n = 3
Two angles are complementary. The measure of one angle is 53°. What is the measure of the other angle
Since the two angles are complementary, their sum is 90 degrees. Let x be the measure of the other angle in degrees. Then:
x + 53 = 90
Subtracting 53 from both sides, we get:
x = 37
Therefore, the measure of the other angle is 37 degrees.

a group of friends wants to go to the amusement park. they have no more than $480 to spend on parking and admission. parking is $8.75, and tickets cost $15.50 per person, including tax. which inequality can be used to determine p, the maximum number of people who can go to the amusement park?
Therefore, the inequality that can be used to determine p, the maximum number of people who can go to the amusement park, is p ≤ 30.
What do you mean by inequalities?In mathematics, inequalities are statements that compare two values or expressions and indicate whether they are equal, greater than, or less than each other. An inequality is typically represented by a symbol, such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to).
Given by the question.
Let's assume that the maximum number of people that can go to the amusement park is p. The cost of parking is $8.75, and the cost of admission for each person is $15.50.
Then, the total cost for p people can be calculated as:
Total cost = (Cost of parking) + (Cost of admission per person x number of people)
Total cost = $8.75 + $15.50p
The group has no more than $480 to spend, so we can set up an inequality:
Total cost ≤ $480
$8.75 + $15.50p ≤ $480
Subtracting $8.75 from both sides:
$15.50p ≤ $471.25
Dividing both sides by $15.50:
p ≤ 30.35
Since the number of people cannot be a decimal, we round down to the nearest whole number: p ≤ 30.

A line that includes the points (t,5) and (10, – 4) has a slope of – 9. What is the value of t? t
Answer:
The value of t is 9.
Step-by-step explanation:
The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:
slope = (y2 - y1) / (x2 - x1)
In this case, we are given two points: (t, 5) and (10, -4), and the slope is given as -9. So we can set up the equation:
-9 = (-4 - 5) / (10 - t)
Simplifying, we get:
-9 = -9 / (10 - t)
Multiplying both sides by (10 - t), we get:
-9(10 - t) = -9
Expanding the left side, we get:
-90 + 9t = -9
Adding 90 to both sides, we get:
9t = 81
Dividing both sides by 9, we get:
t = 9
Therefore, the value of t is 9.

What is the total surface area of the solid?
Enter your answer in the box.
250 is the total surface area of the solid.
How do you determine surface area?
The whole surface of a three-dimensional form is referred to as its surface area. The surface area of a cuboid with six rectangular faces may be calculated by adding the areas of each face.
Instead, you may write out the cuboid's length, width, and height and apply the formula surface area (SA)=2lw+2lh+2hw.
Each side of a cube with side length = 5 has an area of 25; the overall area is 6 x 25 = 150
A cube with sides of length 5 has an area of 25 on each side, making its overall area 6 x 25 or 150.
Both have a combined area of 150 + 150 = 300
300 - 25 - 25 = 250 is the result from each of the two cubes.

The requirements are that the password needs to be 8 characters long considering of 5 lowercase letters followed by 3 numbers. If you are allowed to use characters more than once (with replacement), how many different possibilities are there for a password? (Use an image to help you understand). Let's use the same example as above, only this time you may only use each letter or number one time. That is without replacement or repetition.
Similarly, there are 10 choices for the first number, 9 choices for the second number, and 8 choices for the third number. Therefore, the total number of possibilities is[tex]26 × 25 × 24 × 23 × 22 × 10 × 9 × 8 = 14,776,320[/tex] possibilities.
Fundamental Counting Principle and how to count with and without replacement.The Fundamental Counting Principle (FCP) states that if there are m ways to perform an event and n ways to perform a second event, then there are m × n ways to perform both events. For example, suppose there are 2 shirts, 3 pants, and 4 pairs of shoes in your closet. Using the FCP, you can calculate the number of outfit combinations: 2 × 3 × 4 = 24.If you are allowed to use characters more than once (with replacement), the number of different possibilities for a password can be calculated by multiplying the number of choices for each character type. There are 26 lowercase letters, so there are 26 choices for the first letter, 26 choices for the second letter, and so on. Similarly, there are 10 digits, so there are 10 choices for each number.
Therefore, the total number of possibilities is [tex]26 × 26 × 26 × 26 × 26 × 10 × 10 × 10 = 26^5 × 10^3 = 11,881,376,000[/tex] possibilities.If you may only use each letter or number one time, then you cannot repeat any choices.

b) The angle AOC is 0.523598775 radian
c) The area of the shaded region is 541.9 cm²
d) The perimeter of the shaded region is 106.8 cm.
What is area?The area of a circle is a measure of the size of the surface of the circle. It is calculated by multiplying the radius of the circle (the length from the center of the circle to its edge) by itself, and then multiplying the result by the constant pi (3.14). The formula for calculating the area of a circle is A = πr2, where “A” represents the area, “π” is pi, and “r” is the radius of the circle.
The radius of the circle, r, can be determined by the Pythagorean theorem. Since AC = 36 cm and AP = 6 cm, the hypotenuse of the right triangle formed by AC and AP is the radius of the circle, r. By applying the Pythagorean theorem, we get:

r = √1296
r = 36 cm
b) The angle AOC is 0.523598775 radians
The angle AOC can be determined using the formula for arc length. The arc length of ABC is 36 cm and the radius of the circle is 30 cm. Therefore, the angle AOC is:
AOC = 36/30
AOC = 1.2 radians
c) The area of the shaded region is 541.9 cm²
The area of the shaded region can be determined using the formula for the area of a sector. The angle AOC is 1.2 radians and the radius of the circle is 30 cm. Therefore, the area of the shaded region is:
Area = (1.2)(30)(30)/2
Area = 541.9 cm²
d) The perimeter of the shaded region is 106.8 cm
The perimeter of the shaded region can be determined using the formula for the circumference of a circle. The radius of the circle is 30 cm. Therefore, the perimeter of the shaded region is:

The quadratic function to represent the total area of the park and its path is given by: f(x) = 2x² + 18x + 36.
In this problem, we are given that the length of a rectangular park is twice its width, and it is surrounded by a 3-foot wide path.
We are required to write a quadratic function to represent the total area of the park and its path.
The rectangular park can be represented as follows:
Length = 2x (twice the width)
Width = x
Therefore, the total length of the park including the 3-foot wide path can be represented as (2x + 2*3),
and the total width of the park including the 3-foot wide path can be represented as (x + 2*3).
The area of the park is given by the product of its length and width.
Thus, the area of the park can be represented as follows: Area of the park = (2x + 6)(x + 6)

The equation of the line in slope-intercept form is y = 6x + 55.
Describe Equation?Equations can involve variables, which are placeholders for unknown values that we wish to find. For example, the equation x + 3 = 7 asserts that the value of x plus 3 is equal to 7. We can solve for x by subtracting 3 from both sides of the equation, obtaining x = 4.
Equations can be linear or nonlinear, and they can involve one or more variables. They can be represented in various forms, such as standard form, slope-intercept form, or quadratic form.
To find the equation of the line in point-slope form, we need to first find the slope of the line. We can use any two points from the table to find the slope using the formula:
slope = (change in y)/(change in x)
Let's use the first and last points in the table:
slope = (295 - 175)/(40 - 20) = 120/20 = 6
Now we can use the point-slope form of the equation of a line:
y - y1 = m(x - x1)
where m is the slope and (x1, y1) is any point on the line. Let's use the first point (20, 175):
y - 175 = 6(x - 20)
To write this equation in slope-intercept form, we need to isolate y:
y - 175 = 6x - 120
y = 6x + 55
So the equation of the line in slope-intercept form is y = 6x + 55.

Therefore, a monthly payment of $168.62 must be made to pay off the $3,500 balance on the credit card in two years.
What is percent?Percent is a way of expressing a number as a fraction of 100. The symbol for percent is "%". Percentages are used in many different contexts, such as finance, economics, statistics, and everyday life.
Here,
To calculate the monthly payment required to pay off the $3,500 balance on a credit card that charges 16.5% interest, compounded monthly, in two years, we can use the formula for the present value of an annuity:
[tex]PMT = PV * r / (1 - (1 + r)^{-n})[/tex]
where PMT is the monthly payment, PV is the present value of the loan, r is the monthly interest rate, and n is the total number of payments.
First, we need to convert the annual interest rate of 16.5% to a monthly interest rate:
r = 0.165 / 12
= 0.01375
Next, we need to calculate the total number of payments over two years:
n = 2 * 12

x dimes x 10 cents = $3.10 - (37-x nickels x 5 cents),By dividing both sides of the equation by 10 cents, we can solve for the number of dimes, x:
x dimes = ($3.10 - (37-x nickels x 5 cents)) / 10 cents
Plugging in the value of 37 coins and solving the equation, we get:
x dimes = (3.10 - (37 -x nickels x 5 cents)) / 10 cents
x dimes = (3.10 - 185 + 5x) / 10 centsx dimes = (3.10 - 180) / 10 centsx dimes = 1.30 / 10 centsx dimes = 13 dimes
Therefore, Carter has 13 dimes in his piggy bank.

Produce an equivalent equation for f(x)=7(x-60)-28 to reveal the y-intercept for the function. What is the y-intercept?
The equivalent equation to f(x) = 7(x - 60) - 28 is f(x) = 7x - 448 and the y-intercept is -448
How to determine the equivalent equationGiven that
f(x) = 7(x - 60) - 28
To produce an equivalent equation that reveals the y-intercept of the function f(x) = 7(x-60) - 28, we need to simplify the expression by evaluating it when x = 0, since this will give us the y-intercept.
When the brackets are expanded, we have the following
f(x) = 7x - 420 - 28
Evaluate the like terms
So, we have
f(x) = 7x - 448
So, substituting x = 0 into f(x) gives:
f(0) = 7(0) - 448
Evaluate the expression
f(0) = -448
Therefore, the y-intercept is -448.

PLX SIMPLIFY -2.6+3.9b
Answer: 3.9b−2.6
Step-by-step explanation: Hope this helps
Answer:
1.3b
Step-by-step explanation:
The equation is -2.6+3.9b. A negative number acts like subtraction, so we would subtract 2.6 from 3.9 to get 1.3. The b is still there, and we don't know what it is, so we simplify the equation to 1.3b.

Aron needs 5/7 of a yard of fabric to cover a chair ad 2/3 of a yard of the fabric to cover a footstool. How much more fabric is required for the chair than the footstool?
Answer:
Step-by-step explanation:
To find out how much more fabric is required for the chair than the footstool, we need to subtract the amount of fabric required for the footstool from the amount of fabric required for the chair.
The amount of fabric required for the chair is 5/7 of a yard.
The amount of fabric required for the footstool is 2/3 of a yard.
So to find the difference, we need to subtract:
5/7 - 2/3
To do this, we need to find a common denominator, which is 21 in this case. We get:
(15/21) - (14/21) = 1/21
Therefore, Aron needs 1/21 more yard of fabric to cover the chair than the footstool.
