The probability of selecting a black marble followed by a red marble with replacement is option A: 4.7%.
What is the probability?Based on the question, for one to calculate the probability of selecting a black marble followed by a red marble, we need to look at the two independent events which are:
selecting a black marble selecting a red marble.So, the probability of selecting a black marble on the first draw is:
2 black marbles out of a total of 16 marbles (6 red + 3 yellow + 2 black + 5 pink)
= 2/16 approximately 1/8.
Based on the fact that the marble is replaced, the probabilities for each draw will have to remain the same.
So, the probability of selecting a red marble on the second draw = 6 red marbles out of a total of 16 marbles
= 6/16
= 3/8.
To know the probability of both events occurring, we need to multiply the sole probabilities:
P(black marble and then red marble) = P(black marble) x P(red marble)
= (1/8) x (3/8)
= 3/64
So one can Convert the probability to a percentage, and it will be:
P(black marble and then red marble) = 0.047
= 4.7%

The value of the equation is r = ( 1/2 ) ( A / 3L - πR )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = 3L ( 2r + πR ) be equation (1)
Now , on simplifying the equation , we get
( 2r + πR ) = A / 3L

a) The equation of line is y = 270x + 10640.
b) The annual cost value in 2013 for age 17 is $15,320.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Points (8, 12800) and (14, 14420)
So, the slope is
= (14420 - 12800)/(14-8)
= 1620/6
= 270
and, the slope intercept form
(y - 12800) = 270 (x - 8)
y- 12800 = 270 x - 2160
y = 270x + 10640
b) Now, x= 17
y= 270(17) +10640

Answers
The width of a rectangle that has a length of 24 inches would be 60 inches.
According to the data, we can assume that all the rectangles in the table have the same ratio of measurement.
To find unknown width of the rectangle, we can use this equation:
A/B = C/D
Where:
A represents the length of the first rectangle
B represents the width of the first rectangle
C represents the length of the second rectangle
D represents the width of the second rectangle
In this case, we are going to use 12 as the length of the first rectangle, and 30 as its width.
12/30 = 24/D
12D = (30 x 24)
12D = 720
D = 60

Answers
Answer:
For each service call cost of 20$ will be added to fixed cost of 3000$.
Step-by-step explanation:
The total cost for 1 month is the sum of the fixed monthly cost and the cost of all the service calls, so we can write the equation as:
y = 3000 + 20x
This equation is already in slope-intercept form, where "y" is the dependent variable, "x" is the independent variable, 3000 is the y-intercept (the point where the line crosses the y-axis, when x=0), and 20 is the slope of the line.

Find the maximum value off(x,y) = x^{3}y^{4} for x,y on the unit circle.
Answers
The maximum value of f(x, y) = x3y4 for x, y on the unit circle is 1.
The unit circle is defined as the set of points on a plane that satisfy the equation x2 + y2 = 1. This means that the maximum value of f(x, y) = x3y4 on the unit circle can be found by substituting x2 + y2 = 1 into f(x, y) and solving for x3y4.
We can begin by writing the equation in the following form:
f(x, y) = x3y4 = (x2 + y2)4 = 1⁴ = 1

What is value of x? enter your answer in the box. X = a triangle with vertices labeled as a, b, and c. Side b c is the base. A line segment is drawn from vertex a to base b c that bisects angle b a c into two parts marked with single arcs. Side a b is labeled as 8. Side a c is labeled as 12. Side b c is divided into two equal parts labeled as x plus 4 and 2 x plus 1.
Answers
The value of x calculated by using the Pythagorean theorem is equal to 6.
This can be found by using the Pythagorean theorem to solve for the length of side bc, which is the base of the triangle. By using the two given side lengths of 8 and 12, we can find that the length of the hypotenuse (bc) is equal to the square root of 8^2 + 12^2, which is equal to 16.
Since the base is divided into two equal parts, we can divide 16 by 2 and get 8. We then subtract the given length of 2x + 1 from 8 and get 7, which means x is equal to 6.

A tunnel is constructed with a semielliptical arch. The width of the tunnel is 70 feet, and the maximum height at the center of the tunnel is 20 feet. What is the height of the tunnel 10 feet from the edge? round your answer to the hundredths place.
Answers
Considering the equation of an ellipse, it is found that the height of the tunnel 10 feet from the edge is of 14 feet.
The following is the equation for a horizontal ellipse of center with coordinates (h,k):
(x - h)²/a² + (y - k)²/b² = 1.
In relation to this issue, we have that:
The origin is where the center is.
Since the major axis is 70, 2a = 70 and a = 35.
The maximum height is 20, therefore b is equal to 20.
As a result, the ellipse's equation is as follows:
x²/35² + y²/20² = 1.
It is determined that x = 25 when the tunnel is 10 feet from the edge since 35 – 10 = 25; therefore, the height y is calculated as follows:
25²/35² + y²/20² = 1
0.51 + y²/20² = 1
y²/20² = 0.49
y² = 20² x 0.49
y =√(20² x 0.49)
y = 14 feet.

p(x)=2x+2(x+4) to determine the perimeter of the flower box based on the width x in feet
Answers
Answer: The perimeter of the flower box can be determined by adding up the lengths of all four sides. In this case, we can see that the width of the flower box is represented by the variable x in feet, and the height is given as 2(x+4). To find the perimeter, we need to add up the lengths of the top and bottom (2x) and the left and right sides (2(x+4)). So, the perimeter P(x) can be expressed as:
P(x) = 2x + 2(x+4)
Simplifying this expression:
P(x) = 2x + 2x + 8
P(x) = 4x + 8
So the perimeter of the flower box is 4x+8 feet, based on the width x in feet.

0.9 -0.3
0.5 -0.8
Answers
Answer: The correlation coefficient (also known as Pearson's correlation coefficient or r) is a measure of the strength of the linear relationship between two variables. The value of the correlation coefficient ranges between -1 and 1, with a value of 1 indicating a perfect positive linear relationship, a value of -1 indicating a perfect negative linear relationship, and a value of 0 indicating no linear relationship.
In this case, the correlation coefficient that represents the strongest linear relationship is
0.9
The absolute value of the correlation coefficient measures the strength of the linear relationship, regardless of whether it is positive or negative. So, the absolute value of 0.9 and -0.3 are both 0.9. but as we are looking for the strongest linear relationship, the value of 0.9 is closer to 1 than -0.3 is and it indicates stronger positive relationship.
In summary, the closer the correlation coefficient is to 1 or -1, the stronger the linear relationship between the variables is. In this case, 0.9 has the strongest linear relationship of the given options.
