Probability = the number of ways of achieving success. the total number of possible outcomes. For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail).
Step-by-step explanation:
It’s less then five so all numbers lower then five which is 4 therefore you have the probability of rolling 4 different numbers but u have a 1/4 chance of rolling a 2

Write an equation m=1/3 through (4,4)
Answers
Answer:
y - 4 = 1/3(x - 4)
y - 4 = 1/3x - 4/3
y - 12/3 = 1/3x - 4/3
y = 1/3x + 8/3
Step-by-step explanation:
The slope of a line can be expressed in the form y = mx + b. Given m = 1/3 and a point (4,4), we can substitute these into the equation to find b. The equation of the line is thus y = 1/3x + 8/3.
Explanation:In mathematics, an equation of a line is often written in the slope-intercept form, which is y = mx + b. The term 'm' represents the slope of the line, while 'b' is the y-intercept.
In the question, the value 'm' is provided as 1/3, and one point through which line passes is (4,4). We can substitute the value of 'm' and the coordinates of the point into the equation to solve for 'b'.
So, y = mx + b becomes 4 = (1/3)*4 + b. Simplify this to solve for b, hence b=4-(4/3) which gives 'b' as 8/3.
Therefore, the equation of the line becomes y = 1/3x + 8/3.

Two wires with lengths of 448 cm and 616 cm are to be cut into pieces of all the same length without a remainder. Find the greatest possible length of the pieces?
SOMEBODY PLZ HELP!!! wih this question.
Answers
The greatest possible length for the pieces into which two wires of lengths 448 cm and 616 cm can be cut without a remainder is 56 cm, which is the Greatest Common Divisor of the two lengths.
For the lengths given, 448 cm and 616 cm, the GCD can be found using the Euclidean algorithm.
Divide 616 by 448 and find the remainder: 616 / 448 gives a quotient of 1 and a remainder of 168.
Next, divide the former divisor (448) by the remainder (168) to get a new quotient and remainder: 448 / 168 gives a quotient of 2 and a remainder of 112.
Repeat this process using the previous remainder: 168 \/ 112 gives a quotient of 1 and a remainder of 56.
Continue the process: 112 / 56 gives a quotient and remainder of 2 and 0, respectively.
Therefore, the greatest possible length for equally-sized pieces of wire without remainder is 56 cm.
y = -x^2 + 6x - 5 , zeros
Answers
Answer:
x = 1, x = 5
Step-by-step explanation:
To find the zeros let y = 0, that is
- x² + 6x - 5 = 0 ( multiply through by - 1 )
x² - 6x + 5 = 0 ← in standard form
(x - 1)(x - 5) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 5 = 0 ⇒ x = 5
Simplify the expression. Use standard polynomial format.

Which unit would you need fewer of to measure a tree?
Answers
To measure the height of a tree, feet would be the most suitable unit .
When determining which unit you would need fewer of to measure a tree, it's important to consider units that are an appropriate scale for the object in question. Since a tree is typically more than a few feet tall, but significantly less than a mile tall, we would use feet as the unit of measurement. Using yards would require us to measure in much smaller segments than a whole yard, and using inches would take a long time to measure the full height. Therefore, the most suitable unit to measure the height of a tree would be feet, as this unit provides a balance between precision and efficiency. For fieldwork where estimation of tree density is needed, aspects like basal area might be measured using a factor prism in a defined plot area, such as a 0.04-ha (0.1-acre) plot, to estimate the density of trees in a larger area.

Adan can do a piece of work in 3 days, Bernie in 4 days, and Cynthia in 6 days each working alone.
How long will it take them to do it working together?
Please include how you did it.
Answers
Answer:
1 day and 8 hours
Step-by-step explanation:
Adan does 1/3 work each day,
Bernie does 1/4 work each day, and
Cynthia does 1/6 work each day
combined they accomplish 3/4 each day
therefore it would take them 1 day and 8 hours
By adding the individual work rates of Adan, Bernie, and Cynthia, we find that they could complete the task in a total time of 1.5 days when working together.
Explanation:In this question, the rates at which Adan, Bernie, and Cynthia can complete a piece of work are given. This information can be used to calculate how long it would take for them to complete the work together.
Adan can do the job in 3 days, so his work rate is 1/3 of the job per day. Bernie's work rate is 1/4 of the job per day, and Cynthia's work rate is 1/6 of the job per day.
The combined work rate of Adan, Bernie, and Cynthia per day would be the sum of their individual work rates which is (1/3 + 1/4 + 1/6). This sums up to 4/6 or 2/3. The time required for them to finish the job together is the reciprocal of the total work rate which is 3/2 and that equals to 1.5 days.

25 students in a high school health class are asked to write down what foods they ate last week. Of the 25
students, 14 write steak, 6 write chicken, and 5 write both steak and chicken. Using this information, answer
each of the following questions,
Let S be the event that a randomly selected student writes steak and C be the event that a randomly selected
student writes chicken.
What is P(S), the probability that a student writes steak?
What is P(C), the probability that a student writes chicken?
What is P(S and C), the probability that a student writes steak and chicken?
What is P(S or C), the probability that a student writes steak or chicken?
Answers
The probability of event S(students writing steak) was calculated as 14/25, event C(students writing chicken) as 6/25, while both occurring(S and C) as 5/25. From these the combined probability of either of these two events occurring(S or C) was determined by summing the individual probabilities and subtracting the combined one thus, 14/25+6/25-5/25.
Explanation:The subject matter relates to the field of probability in Mathematics, focusing on two independent events namely, S (student writes steak) and C (student writes chicken). Here, the total number of students 25 serves as our sample space.
The probability of event S, P(S), is equal to the number of students who write steak over the total number of students. So, P(S) = 14/25. The probability of event C, P(C), is similarly calculated. That is, P(C) = 6/25.The probability that both events S and C occur, denoted as P(S and C), can be obtained by the division of the number of students who write both steak and chicken by the total number of students. So, P(S and C) = 5/25.The probability that either event S or C occur, written as P(S or C) is calculated by adding the probabilities of each event and then subtracting the probability of them occurring together. Thus, P(S or C) = P(S) + P(C) - P(S and C) = 14/25 + 6/25 - 5/25.Learn more about Probability here:https://brainly.com/question/32117953

Greg is buying a bike on a payment plan. The equation y=20x+600 models the amount he has left to pay, where x is the number of weeks and y is the amount of money owed in dollars. Lin is also buying a bike on a payment plan. The bike costs 500. She will pay 25 each week. Which statement correctly compares Greg's function and Lin's function.
Answers
We can conclude that the amount owned by Greg is greater than that of Lin. Plus, Greg Also took an additional loan of $600. Lin will pay of the debt in x = 20 weeks, but since no data is given for Greg, it is not possible to determine the time it will cost him to return money.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have the following problem -
Greg who is buying a bike on a payment plan. The equation y = 20x + 600 models the amount he has left to pay, where [x] is the number of weeks and [y] is the amount of money owed in dollars. Lin is also buying a bike on a payment plan. The bike costs 500. She will pay 25 each week.
The equation for Greg payment plan -
y = 20x + 600
models the amount he has left to pay, where [x] is the number of weeks and [y] is the amount of money owed in dollars.
Similarly, the equation that represents the money owned by Lin -
y = 500 - 25x
[x] is the number of weeks and [y] is the amount of money remaining to be paid in dollars.
Refer the graph of both situations.
The amount owned by Greg is greater than that of Lin. Plus, Greg Also took an additional loan of $600. Lin will pay of the debt in x = 20 weeks, but since no data is given for Greg, it is not possible to determine the time it will cost him to return money.
Therefore, we can conclude that the amount owned by Greg is greater than that of Lin. Plus, Greg Also took an additional loan of $600. Lin will pay of the debt in x = 20 weeks, but since no data is given for Greg, it is not possible to determine the time it will cost him to return money.

Find the measure of arc DBC in circle P.
Answers
Answer:
122°
Step-by-step explanation:
The measure of arc DBC in circle P is calculated thus:
DBC = 180° - 58° (sum of angles on a straight line)
DBC = 122°
Therefore, the measure of arc DBC in circle P is 122°.
Note,
Line BD is a straight line; thus, sum of angles on a straight line is 180°.
Angle BPC is 58°. To determine angle DPC, we subtract 58° from 180°, such that, 180° - 58° = 122°.
Wheel A has a diameter of 25.4 inches. Wheel B has a diameter of 22.5 inches. About how much farther will Wheel A travel in one rotation than Wheel B? Use 3.14 for pi. Round your answer to the nearest whole number.
Answers
Wheel A will travel a distance of approximately 9 in more than wheel B in one rotation.
Explanation:
Given:
Diameter of wheel A, d₁ = 25.4 in
Radius of wheel A, r₁ = 12.7 in
Diameter of wheel B = 22.5 in
Radius of Wheel B, d₂ = 11.25 in
Distance travelled by A = ?
In one rotation, the distance travelled by a wheel is equal to its circumference.
Circumference of a wheel = 2πr
Circumference of wheel A = 2πr₁
= 2 X 3.14 X 12.7 in
= 80 in
Circumference of wheel B = 2πr₂
= 2 X 3.14 X 11.25 in
= 71 in
Therefore, wheel A will travel a distance of approximately 9 (80 - 71 in) in more than wheel B in one rotation.
The larger wheel with a diameter of 25.4 inches travels approximately 9 inches farther in one rotation than the smaller wheel with a diameter of 22.5 inches.
To determine how much farther Wheel A will travel in one rotation compared to Wheel B, we need to calculate the difference in their circumferences, since the circumference of a wheel determines the distance it covers in one rotation. The formula for the circumference of a circle is C = (pi * d), where C is the circumference and d is the diameter of the wheel.
First, we calculate the circumferences of both wheels:
Wheel A: C = (pi * d) = 3.14 * 25.4 inches = 79.756 inches.
Wheel B: C = (pi * d) = 3.14 * 22.5 inches = 70.65 inches.
Now, to find how much farther Wheel A travels than Wheel B in one rotation, we subtract the circumference of Wheel B from that of Wheel A:
Difference in distance = Circumference of Wheel A - Circumference of Wheel B = 79.756 inches - 70.65 inches = 9.106 inches.
When rounding to the nearest whole number, the difference is approximately 9 inches.
