Final answer:
The probability that a randomly selected golf ball will be red from a basket of 18 balls, with 9 red, is 1/2 or 50%.
Explanation:
The question is asking about the probability of selecting a red golf ball from a basket that contains 18 golf balls, with 9 of them being red. To find this probability, we divide the number of red golf balls by the total number of golf balls.
Here is the calculation:
Number of red golf balls: 9
Total number of golf balls: 18
Probability (P) of selecting a red golf ball: P = Number of red golf balls / Total number of golf balls
P = 9 / 18
P = 1/2 or 0.5 or 50%
Therefore, the probability that a randomly selected golf ball will be red is 1/2, which can also be expressed as 0.5 or 50%.

B. Multiplying the function by 1
C. Subtracting 1 from the function
A. multiplying the function by -1
Multiplying the function by –1 is the operation flips the graph of a function over the x-axis
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The operation that flips the graph of a function over the x-axis is multiplying the function by -1.
When a function is multiplied by -1, the y-values are negated, which causes the graph to reflect over the x-axis.
if we have a function f(x) = x², the graph will be a parabola that opens upwards.
However, if we multiply this function by -1 to get -f(x) = -x², the graph will be the same parabola reflected over the x-axis and opening downwards.
Hence, Multiplying the function by –1 is the operation flips the graph of a function over the x-axis

10.5
Answer:
13.5
Step-by-step explanation:
The geometric representation of an integral is the area below the curve. So, let's graphic the function.
[tex]f(x) = 3[/tex] is an horizontal line, (y = 3)
and [tex]f(x) = 6-x[/tex] is also a line, but it is decreasing.
We can see in the image that the area below the curve happens to be a polygon. In order to calculate the area we are going to separate it into simpler polygons: a square and a triangle.
The area of the square is [tex]3*3 = 9[/tex].
The area of the triangle is [tex]\frac{3*3}{2} = \frac{9}{2} = 4.5[/tex]
If we add them, we get
[tex]\int_0^6 f(x) dx =9 + 4.5 = 13.5[/tex]

Given a right cone with base area b and height h, what is the formula for the volume?
The volume of a cube with sides of length s is given by v = s3. find the rate of change of the volume with respect to s when s = 3 centimeters.
Final answer:
The rate of change of the volume of a cube with respect to its side length s, when s = 3 cm, is 27 cubic centimeters per centimeter.
Explanation:
The volume V of a cube with sides of length s is given by V = s³. To find the rate of change of the volume with respect to s when s = 3 cm, we need to differentiate the volume function V(s) with respect to s. The derivative of V with respect to s is [tex]\frac{dV}{ds}[/tex] = 3s². When s = 3 cm, [tex]\frac{dV}{ds}[/tex] = 3(3)² = 3(9) = 27. The rate of change of the volume when s = 3 cm is 27 cubic centimeters per centimeter.

Amelia, Luis, Shauna, and Clarence used different approaches to solve the inequality 7.2b + 6.5 > 4.8b – 8.1. Amelia started by subtracting 7.2b from both sides to get 6.5 > –2.4b – 8.1. Luis started by subtracting 4.8b from both sides to get 2.4b + 6.5 < – 8.1. Shauna started by subtracting 6.5 from both sides to get 7.2b > 4.8b – 14.6. Clarence started by adding 8.1 to both sides to get 7.2b + 14.6 > 4.8b. Which student’s first step was incorrect, and why? Amelia’s, because the variable term must be isolated on the left side Luis’s, because he flipped the inequality sign when he subtracted Shauna’s, because she did not apply the subtraction property of equality properly Clarence’s, because the terms he added together were not like terms

Which unit fraction should be used to convert 15 inches to centimeters?
To convert from inches to centimeters, the unit fraction used is 2.54 cm/1 in. Therefore, 15 inches is equal to 38.1 centimeters.
Explanation:To convert a measurement from inches to centimeters, we utilize a unit conversion factor. In this instance, the unit conversion factor we're interested in relates inches to centimeters. One inch is equivalent to 2.54 centimeters. Hence, the unit fraction used for such conversion is 2.54 cm/1 in.
To determine the equivalent value in centimeters for 15 inches, we multiply the number of inches (15) by our unit conversion factor (2.54 cm/1 in). This gives us the following
15 inches * 2.54 cm/1 in = 38.1 cm.
So, 15 inches is equivalent to 38.1 centimeters when converted.

The tooth fairy brings jack $5 plus $1 for each tooth that he loses. After jack loses a few teeth, the tooth fairy decides that he is paying too much money for teeth. He is gives jack $5 plus $0.50 for each tooth lost. Which graph shows the new function?
Answer:
The new function is [tex]y=0.5x+5[/tex] and its graph is shown below.
Step-by-step explanation:
Let the number of tooth = x and the cost of teeth = y (in dollars).
Tooth fairy charges $1 for each tooth with extra charge of $5.
So, the cost of the teeth is [tex]y=x+5[/tex].
Now, the tooth fairy charges $0.5 for each tooth with extra charge of $5.
Thus, the new cost of the teeth is given by.
[tex]y=0.5x+5[/tex]

This means that two positive numbers have given a difference of -5, so the conclusion above can not be true. In fact, subtracting a larger number from a smaller number will always give a negative result, so this conclusion isn't even true in most cases.
I'm always happy to help :)The sum of two numbers is 39 . the larger number is 17 more than the smaller number. what are the numbers?
The smaller number is 11 and the larger number is 28.
Explanation:Let's assume the smaller number is 'x'.
The larger number is 17 more than the smaller number, so the larger number can be represented as 'x + 17'.
The sum of the two numbers is 39, so we can set up the equation: x + (x + 17) = 39.
By simplifying the equation, we get 2x + 17 = 39.
Subtracting 17 from both sides gives us 2x = 22.
Dividing both sides by 2 gives us x = 11.
So, the smaller number is 11 and the larger number is 11 + 17 = 28.

On the first day of summer a rainstorm brought 2.29 inches of rain to the area. During the rest of the summer there was 3 times as much rain as on the first day. What was the total number of inches of rainfall for the summer?
To solve this problem, we simply have to multiply the original inches of rain to that of how many times it was for the rest of summer. So in this case, simply multiply 2.29 by 3, that is:
2.29 inches * 3 = 6.87 inches
Answer:
6.87 inches
