What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
We have to given that;
To find the probability of getting an odd number on a spinner with 5 equal parts numbered 1 to 5.
Since, From 1 to 5, there are three numbers 1, 3, 5 are odd numbers.
Hence, the probability of getting an odd number on a spinner with 5 equal parts numbered 1 to 5 is,
P = 3/5
Change into percent as;
P = 3/5 x 100%
P = 60%
Thus, the probability of getting an odd number on a spinner with 5 equal parts numbered 1 to 5 is, 60%

Mary and Jerry are exercising on a track
-Mary is walking at a rate of 3 miles per hour
-Jerry starts jogging at a rate of 4 miles per hour after Mary has been walking for 15 minutes
-Jerry jogs 2 miles as Mary continues walking and they both stop at the same time
Enter the total distance, in miles, that Mary walks around the track
Answer:
2.25
Step-by-step explanation:
Mary walks for 15 mins which is 0.75 mi. Jerry then starts jogging for 2 miles which is 30 minutes because he is jogging at 4 mph. This means Mary walked for 30 minutes which is 1.5 mi.
0.75+1.5=2.25

what is 15% of "x"
PLEASE HELP
Answer:
0.15x
Step-by-step explanation:
15% of anything is 15/100 or 0.15 of it. You find that value by multiplying the "anything" by 0.15.
Since we don't know the value of x, the best we can do is show that the number of interest is x multiplied by 0.15.
Line segment AB has endpoints A(10, 4) and B(2, 8). Find the coordinates of the point that divides the line segment directed from A to B in the ratio of 1:4.
The coordinates of the point that divides the line segment AB in the ratio of 1:4 are (8, 6).
Explanation:To find the coordinates of the point that divides the line segment AB in the ratio of 1:4, we can use the formula:
x = (x1 + 1/n * (4 * x2)) / (1 + 1/n)
y = (y1 + 1/n * (4 * y2)) / (1 + 1/n)
Substituting the given coordinates into the formula, we have:
x = (10 + 1/4 * (4 * 2)) / (1 + 1/4) = 8
y = (4 + 1/4 * (4 * 8)) / (1 + 1/4) = 6
Therefore, the coordinates of the point that divides the line segment AB in the ratio of 1:4 are (8, 6).

one month charlie rented 2 movies 3 video games for a total of $21. The next month he rented 4 movies and 8 video games for a total of $53. Find the rental cost of each movies and each video game.
The cost to rent a movie is $2.25 and to rent a video game is $5.50, which was determined by solving a system of linear equations derived from the problem statement.
Explanation:This problem is a classic example of a system of linear equations, and we can solve it using either substitution or elimination method. Let's denote the cost of renting a movie as 'm' and the cost of a video game as 'v'. From the problem statement, we know:
2m + 3v = $214m + 8v = $53We can multiply the first equation by 2, giving us 4m + 6v = $42. Now if we subtract the second equation from this, we can solve for 'v':
(4m + 6v) - (4m + 8v) = $42 - $532v = $11v = $5.50Substitute 'v' back into the first equation to solve for 'm':
2m + 3($5.50) = $212m + $16.50 = $212m = $4.50m = $2.25Therefore, the cost to rent a movie is $2.25 and to rent a video game is $5.50.

d=1/2at^2 ; for a
solve for a
Answer:
a = 2d/t²
Step-by-step explanation:
1- Divide by 1/2 on both sides:
(d ÷ 1/2 = d × 2/1 = 2d)
2d = at²
2- Divide by t² on both sides:
2d/t² = a
a = 2d/t²

This table shows the size, in acres, of four large water parks. What is the median of the sizes of the four water parks? 60 acres 63 acres 64 acres 65 acres Park Size (in Acres) A 66 B 70 C 60 D 60
The median size of the four water parks, given as 66, 70, 60, 60 acres, is 63 acres.
Explanation:To find the median of the sizes of the four water parks, we first need to list the sizes in ascending order. Given the sizes are 66, 70, 60, 60, the arranged list becomes 60, 60, 66, 70.
As there are four numbers, the median is the average of the middle two numbers. So by adding 60 and 66 and then dividing by 2, we find that the median size of the water parks is 63 acres.

what are the factors of 2n^2 -5n- 42
The factors of the quadratic expression 2n^2 - 5n - 42 are found by looking for two numbers that multiply to -84n^2 and add up to -5n. The correct pair is 7n and -12n, leading to the factors (2n + 7) and (n - 6).
Explanation:The factors of 2n^2 - 5n - 42 need to be determined by finding two numbers that multiply to 2n^2 times -42 (which is -84n^2) and add up to -5n. To factor this quadratic expression, we should look for a pair of numbers that meet these criteria.
Upon inspecting possible pairs, we find that 7n and -12n are the numbers that work since (7n) * (-12n) = -84n^2 and 7n + (-12n) = -5n. The quadratic trinomial can be expressed as:
2n^2 - 5n - 42 = (2n + 7)(n - 6)
By factoring this way, we have broken down the expression into its factors, which are (2n + 7) and (n - 6).
The factors of the quadratic expression [tex]\(2n^2 - 5n - 42\)[/tex] are [tex]\(2n + 7\)[/tex] and [tex]\(n - 6\)[/tex].
To find the factors of the quadratic expression \(2n^2 - 5n - 42\), we can use the factoring method. This involves finding two numbers that multiply to give the product of the coefficient of \(n^2\) (which is 2) and the constant term (which is -42), and also add up to the coefficient of \(n\) (which is -5).
The product of the coefficient of [tex]\(n^2\)[/tex] and the constant term is:
[tex]\(2 \times -42 = -84\)[/tex]
Now we need two numbers that multiply to -84 and add up to -5. These numbers are -12 and 7 because:
[tex]\(-12 \times 7 = -84\)[/tex]
[tex]\(-12 + 7 = -5\)[/tex]
Now we can rewrite the middle term of the quadratic expression using -12 and 7:
[tex]\(2n^2 - 12n + 7n - 42\)[/tex]
Next, we can factor by grouping. Group the first two terms and the last two terms:
[tex]\(2n(n - 6) + 7(n - 6)\)[/tex]
Notice that [tex]\(n - 6\)[/tex] is a common factor. We can factor this out:
[tex]\((2n + 7)(n - 6)\)[/tex].

The table below shows the deliveries for Floral World for the week. What is the mean, or average, number of deliveries per day?
Answer:
The average number of deliveries per day is 16 deliveries.
Step-by-step explanation:
The mean of a data set is the average value within it. Means are used as a way of describing data and finding the central tendency. To calculate the mean of a data set, add all values of all data points, then divide the resulting number by the amount of data points.
13 + 15 + 17 + 19 + 16 = 80
80 / 5 = 16
So, the average number of deliveries made per day by Floral World is 16 deliveries.
Jason is covering an ottoman with fabric. The ottoman is in the shape of a rectangular prism that is 37 cm long, 21 wide, and 30 cm high. How much fabric is needed to cover the sides and top of the ottoman? Explain your strategy.
Final answer:
Jason needs 4,257 square centimeters of fabric to cover the sides and top of his rectangular prism shaped ottoman, calculated by finding the area of each side and adding them together.
Explanation:
To calculate the amount of fabric needed to cover the sides and top of a rectangular prism shaped ottoman with dimensions 37 cm in length, 21 cm in width, and 30 cm in height, we start by determining the surface area of the ottoman that needs covering. We ignore the bottom surface, assuming the ottoman sits directly on the floor.
First, calculate the area of each side:
Top/bottom surface (only top applies here) = length × width = 37 cm × 21 cm = 777 cm²
Front/back surface = length × height = 37 cm × 30 cm = 1,110 cm² (two sides, so × 2)
Left/right side = width × height = 21 cm × 30 cm = 630 cm² (two sides, so × 2)
Next, add all the calculated areas together:
777 cm² (top) + 2,220 cm² (front/back) + 1,260 cm² (left/right) = 4,257 cm²
Therefore, Jason needs 4,257 square centimeters of fabric to cover the sides and top of the ottoman.

a $1,400 loan has a simple annual interest rate 4%. how much simple interest is paid on the loan for 1 year?
The simple interest paid on a $1,400 loan with an annual interest rate of 4% for 1 year is $56.
Explanation:The subject of your question is simple interest calculation. The formula for calculating simple interest is: principal amount x interest rate x time. You are asked to calculate the simple interest paid on a $1,400 loan with an annual interest rate of 4% for 1 year. Let's proceed step-by-step:
Convert the interest rate of 4% to a decimal by dividing by 100. So, 4/100 = 0.04.The time is 1 year, so you don't need to convert it.Substitute the values into the simple interest formula. Therefore, the simple interest is: $1,400 x 0.04 x 1 = $56.So, the simple interest paid on the loan for 1 year is $56.
