Describe frequency, relative frequency, and cumulative relative frequency.
Frequency :
The frequency of a particular data is the number of times the particular data value occurs. We represent the value of frequency as f.
Relative frequency :
Relative frequency is the fraction or proportion times an answer occurs in the data set.
Relative frequency can be written in decimal, fraction and percent.
To find the relative frequency, divide the frequency by the total number of data values.
Cumulative frequency :
Cumulative frequency is the collection of all previous frequencies together.
Cumulative frequency is also called frequency of non-exceedance.
There are two types of Cumulative Frequency Curves (or Ogives) :
1. More than type Cumulative Frequency Curve.
2. Less than type Cumulative Frequency Curve.

24c + 60 = 36c
Please explain step by step to get marked as brainliest
Answer:
c = 5
Step-by-step explanation:
You want to solve 24c +60 = 36c.
2-step equationThis is sometimes referred to as a "2-step linear equation," because it can be solved in two steps.
The first step collects the variable terms on one side of the equal sign. This is done by subtracting the unwanted variable term from both sides of the equation.
24c +60 -24c = 36c -24c . . . . . . subtract 24c
60 = 12c . . . . . . . . . collect terms
The second step is to divide by the coefficient of the variable. This gives you the variable by itself:
60/12 = (12c)/12
5 = c . . . . . . . . . . . perform the division
The solution is c = 5.
__
Additional comment
As you can see, we like to write the answer as "variable = constant." We solved the equation to give "constant = variable." Of course, the properties of equality tell you these are interchangeable forms.
The point here is that some folks unnecessarily go to the trouble to manipulate the equation so the variable term ends up on the left. The solution is just as valid when the variable term ends up on the right side of the equal sign.
If you recognize that all of the numbers have a common divisor of 12, you can divide by that first:
24c +60 = 36c
2c +5 = 3c
Then subtract the variable term on the left to get the answer.
2c +5 -2c = 3c -2c
5 = c
Mineko had a piece of material that was 3/5 yard long. She cut 1/3 yard off the material to make a pillow. How much material does she have left?
The material that she has left after the cut of 1/2 yard of the material is 2/5 yards left
While I show you how to solve this problem, I would like to highlight some of the words and how they convert into a mathematical equation.
"She cut 1/3 yard off the material."
This means you multiply whatever you are starting with by 1/3.
So in this case Mineko begins with 3/5 yards.
So,
3/5 • 1/3 = 1/5
She used 1/5 yard to make the pillow.
This will translate to Mineko having left
Therefore 3/5-1/5
She has 2/5 yards left.

Solved Calculate the interest earned on a $4500 saving
The interest earned almost is $337.50 when a $4,500 type of saving account have earns 2.5% simple interest for almost 3 years.
Simple Interest = Principal x Interest Rate x Time/ 100
The principal of a loan or the initial deposit into a savings account serves as the foundation for simple interest. Simple interest does not compound, so the creditor only has to pay interest on the principal sum and the borrower never has to pay interest on the interest that has already accrued.
The principal, or initial amount of a loan, is used to compute simple interest. Compound interest is often referred to as "interest on interest" since it is computed using the main amount and the interest that has accrued over the course of previous periods.
Here Principal= 4500
Rate= 2.5%
Time= 3 years
Using Simple Interest
SI = ( P x R xT)/100
SI = (4500 x 2.5 x 3) /100
SI = 33750/100
SI = $337.50
Hence, the interest earned is $337.50

the customer asked the pro shop to string 10 new rackets at 58 psi suppose the two tailed p value forthe test described above is .09
There is sufficient evidence to conclude that μ, the true mean tension of the rackets, is less than 58 PSI.
The customer determined the tension of each racket after receiving them and came up with the following summaries: 0.9 PSI of standard deviation, 58 as the sample mean.
When we choose alpha as 5% = 0.05, it means that we reject the null hypothesis whenever the p value from the hypothesis test is less than this. If not, we will accept the null hypothesis.
You can use a p value as low as 0.05 and still reject the null hypothesis H0.
On calculating the p value we get it as less than 0.05.
Therefore, we will accept the null hypothesis.

What are right angle properties?A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any one angle is a right angle.
Therefore, this triangle is sometimes called the right triangle or 90-degree triangle.
The characteristics a right-angle triangle possesses.
The right angle, or 90°, is always one angle.The hypotenuse is the side with the 90° angle opposite.The longest side is always the hypotenuse.The other two inner angles add up to 90 degrees.Base and perpendicular are the names of the other two sides that are close to the right angle.Right-angle triangles have an area equal to half of the product of their neighboring sides, or Right-angle triangle's area is equal to (1/2) × base × perpendicular.Let x be the one side of the triangle.
Then the other side will be x + 1 cm.
Hypotenuse is 5 cm.
Using right angled triangle property and (a + b)²=a²+b²+2ab
[tex]x^2 + (x+1)^2 = 5^2\\\implies x^2 + x^2 + 2x + 1 = 25\\\implies 2x^2 + 2x = 24\\\implies 2x^2 + 2x -24 = 0\\\implies x^2 + x -12 = 0\\[/tex]
Solving this equation:
x = -4 or x = 3
since the length of triangle can't be negative therefor x = 3.
which means sides are 3, 4 and 5
Perimeter = sum of all three side
Therefore, Perimeter = 3 + 4 + 5 = 12cm.
Area = (height * base)/2

A charity is considering the possibility of having a benefit night at two different restaurants. The owner of the local Italian restaurant has offered to make a donation of $20 and $2 per diner that night. On the other hand, the owner of the Mexican restaurant has said he could contribute $30 plus $1 per diner. Based on the number of diners who have promised to participate in the event, it appears that each restaurant would donate the same total amount. How much would each restaurant donate?
Answer:
Let's call the number of diners at the Italian restaurant x, and the number of diners at the Mexican restaurant y. We can set up the following system of equations to represent the problem:
Italian restaurant: $20 + 2x = $30 + $1y
Mexican restaurant: $30 + $1y = $20 + 2x
Subtracting $20 from both sides of the first equation and $30 from both sides of the second equation, we get:
Italian restaurant: 2x = $10 + $1y
Mexican restaurant: $1y = $10 + 2x
Multiplying both sides of the first equation by 1/2, we get:
x = $5 + $0.5y
Substituting this expression for x in the second equation, we get:
$1y = $10 + 2($5 + $0.5y)
Expanding the expression on the right side, we get:
$1y = $10 + $10 + $1y
Subtracting $1y from both sides, we get:
0 = $10
This equation is true, so the system of equations is consistent.
Since the total donations from each restaurant would be the same, we can set the total donations equal to each other and solve for the number of diners at each restaurant. The total donation from the Italian restaurant is $20 + 2x, and the total donation from the Mexican restaurant is $30 + $1y. Setting these expressions equal to each other, we get:
$20 + 2x = $30 + $1y
Subtracting $20 from both sides and $1 from both sides, we get:
2x - 2 = $10 + $1y - $1
Combining like terms on both sides, we get:
2x - 2 = $10 + $1y - $1
2x - 2 = $9 + $1y
2x - $9 - $1y = 2 - $9
2x - $1y = -$7
Dividing both sides by 2, we get:
x - $0.5y = -$3.5
Substituting this expression for x in the first equation, we get:
$20 + 2(-$3.5) = $30 + $1y
Simplifying the expression on the left side, we get:
$20 - $7 = $30 + $1y
Subtracting $20 from both sides, we get:
-$7 = $10 + $1y
Subtracting $10 from both sides, we get:
-$17 = $1y
Dividing both sides by -1, we get:
$17 = -$1y
Multiplying both sides by -1, we get:
-$17 = $1y
Dividing both sides by $1, we get:
-$17/$1 = $1y/$1
Simplifying the expression on the left side, we get:
-17 = y
Thus, the number of diners at the Mexican restaurant is -17, and the number of diners at the Italian restaurant is x = $5 + $0.5y = $5 + $0.5(-17) = $5 - $8.5 = -$3.5.

Ping is sewing a square tablecloth. The table she wants to cover is 5.5 feet on each side and she wants it to hang over on each side 9 inches. How many square feet of fabric will Ping need?
I've answered this question in two ways and I think I get to the right answer the second time but it's driving me crazy why it doesn't work the first way.
First way:
The cloth is now a rectangle length 66 in (5.5 feet x 12) by 75 in (5.5 feet x 12, plus 9).
a=l*w=66x75=4950 inches÷12 =412.5 sq ft.
Checking my answer for reasonableness, I thought, but if I just multiply 5.5 feet x 5.5 feet , sans adjustments, I get 30.25.
Second way: 9 inches/12 = .75 ft 5.5+.75 = 6.25 ft, and 5.5 x 6.25 ft = 34.375 SQ ft, makes much more sense. But WHY?
Answer:
The first way is rectangular. You also converted it wrong for the first one. the inches aren's squared. you're converting regular inches into regular feet, instead it should be square inches into square feet.
And Ping is sewing a square tablecloth, not a rectangular one. you have to add the 9 inches on both sides, not just one. You can convert it either way you want, but you have to add the 9 inches to both.

That means p-value is greater that significance level.
And we know that if p-value is greater than significance level then the effect is statistically not significant. There is no enough evidence to reject the null hypothesis.
A p-value greater than 0.01 means that deviation from the null hypothesis is not statistically significant, and the null hypothesis is not rejected.
High p-value indicates that your evidence is not strong enough to suggest an effect exist in the population. An effect might exist but it's possible that the effect size is too small, that sample size is too small or there is too much variability for the hypothesis test to detect it.

What is time period?
The duration of time that a behavior lasts or a condition persists. Depending on the type of activity or situation under consideration, it may be measured in seconds or in millions of years.
Given function that represents height of the projectile above the ground is s feet is s = - 16t² + 112t.
To find the time period is the projectile at least 160 feet above the ground, make an inequality:
- 16t² + 112t ≥ 160
Subtract 160 from both sides:
- 16t² + 112t - 160 ≥ 0
Divide both sides by 16:

The vertex form of the quadratic function f (x) = x² + 8x + 7 is
f(x)= a(x-h)² + k.
What is the value of a?
What is the value of h?
What is the value of k?
Answer:
Step-by-step explanation:
The vertex form of a quadratic function is given by the equation f(x) = a(x - h)² + k, where (h, k) is the coordinates of the vertex of the parabola, and a is a constant coefficient.
To find the values of a, h, and k for the given quadratic function f(x) = x² + 8x + 7, we can first use the formula for the x-coordinate of the vertex of a quadratic function, which is given by h = -b / 2a. In this case, the quadratic function is f(x) = x² + 8x + 7, so b = 8 and a = 1. Plugging these values into the formula, we get:
h = -8 / 2(1) = -4
Therefore, the value of h is -4.
Next, we can use the formula for the y-coordinate of the vertex of a quadratic function, which is given by k = f(h) = a(h - h)² + k. In this case, we know that the value of h is -4, and we can plug this value into the original quadratic function to get the value of k:
k = f(-4) = (-4)² + 8(-4) + 7 = 16 - 32 + 7 = -9
Therefore, the value of k is -9.
Finally, we can use the equation f(x) = a(x - h)² + k to find the value of a. Since we know that the coordinates of the vertex are (-4, -9) and the equation of the quadratic function is f(x) = x² + 8x + 7, we can plug these values into the equation to solve for a:
f(x) = a(x - h)² + k
x² + 8x + 7 = a(x - (-4))² + (-9)
We can then distribute the squared term and simplify the equation to get:
x² + 8x + 7 = a(x² - 8x + 16) + (-9)
x² + 8x + 7 = a(x²) - 8a(x) + 16a + (-9)
We can then collect like terms to get:
x² + 8x + 7 = a(x²) - 8ax + 16a - 9
Comparing the coefficients of the x², x, and constant terms on both sides of the equation, we can see that a = 1.
Therefore, the values of a, h, and k for the given quadratic function f(x) = x² + 8x + 7 are a = 1, h = -4, and k = -9.

Choose the expression that is equivalent to fraction with 8 raised to the negative tenth power in the numerator and 8 raised to the fourth power times 8 raised to the zero power in the denominator.
Group of answer choices
1 divided by 8 raised to the fourteenth power
814
negative 1 divided by 8 raised to the fourteenth power
−814
To find the equivalent expression, we can simplify the fraction by using the rule for exponents that says that when we divide two powers with the same base, we can subtract the exponents. Using this rule, we get:
(8^(-10)) / (8^4 * 8^0) = 8^(-10) / 8^4 = 8^(-10+4) = 8^(-6)
So the equivalent expression is: 1/8^6 = 8^(-6)
The correct answer is: 1 divided by 8 raised to the fourteenth power = 8^(-6)
To find the equivalent expression for the fraction 8^(-10)/8^4*8^0, we can use the property of exponents that states that any number raised to the power of 0 is equal to 1. Therefore, 8^0 is equal to 1.
Using the quotient rule of exponents, which states that when dividing two powers of the same base, we can subtract the exponents, we can simplify the expression to:
8^(-10)/8^4*8^0 = 8^(-10)/8^4 * 1 = 8^(-6).
Therefore, the equivalent expression to 8^(-10)/8^4*8^0 is 8^(-6). The correct answer is therefore 1 divided by 8 raised to the fourteenth power, or option A.

Answer this for 5 star! Need explanation
Answer: 6
Step-by-step explanation: To solve we first start by adding like terms in our equation which is 30 + 54 = x(5+9) which becomes 84=x(14). Now we need to isolate the x variable by dividing both sides by 14.
x(14) ÷ 14 = x, 84 ÷ 14 = 6
This leaves us with the answer x = 6
Which functions are increasing?; How to know if a function is increasing or decreasing?; Which section of the function is increasing?; Which type of increasing function eventually exceeds all other increasing functions?
Linear, polynomial, and quadratic functions can be both increasing or decreasing functions. Exponential function is monotonically increasing function. The derivative of a function may be used to determine whether the function is increasing or decreasing. Exponential functions eventually exceed all other increasing functions.
Function, in mathematics, refers to an expression or rule that describes a relationship between two or more variables. A function is said to be an increasing function when the y-value increases as the x-value increases and vice versa. In order to determine whether the function is increasing or decreasing, the derivative of a function may be used on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I. From the given function options, Exponential functions eventually exceed all other increasing functions as the one of variable is in the exponential leading an exponential increase and not a constant increase.
Note: The question is incomplete. The complete question probably is: From the following, Which functions are increasing? How to know if a function is increasing or decreasing?; Which section of the function is increasing?; Which type of increasing function eventually exceeds all other increasing functions? A) linear B) exponential C) polynomial D) quadratic.

1. 8x+3y-x-2y
triangle abc was translated according to the rule t4.5, –6.2(x, y) to form a’b’c’ as shown. what are the coordinates of point c of the pre-image?
The coordinates of point C are (-5.5, 3.2)
Coordinates:
A coordinate is a set of numbers that describes a point in a specific space. It is used to pinpoint a location, whether on a map, a graph, a plane, or in a three-dimensional space. In 2-D space, coordinates are usually written in the form (x, y), where x indicates the horizontal position and y is the vertical position of the point. In 3-D space, a third coordinate (z) is needed to specify the depth. Coordinates are also used to identify points on a graph. Finally, coordinates can be used to define a plane in three-dimensional space, where 3 coordinates are needed to define the plane’s position.
Given,
(x,y) = (x + 4.5, y -6.2)
So,
(x + 4.5, y -6.2) = (-1,-3)
Therefore;
x + 4.5 = -1
= -1 - 4.5
= -5.5
y - 6.2 = -3
= - 3 + 6.2
= 3.2
hence, the coordinates of point C are (-5.5, 3.2)
