To find the students in the group, simply add up the frequency from each mark. I'll give you an example solution, but I challenge you to do this on your own!
For example, say that there are 4 students with 3 marks and 6 students with 4 marks. There are then 4+6=10 total students in the group
To find the mean, simply add up all up the marks with the amount of frequencies and divide it by the amount of students.
Take our example from earlier - we can write it as a list. Since there are 4 students with 3 marks, we have
3, 3, 3, 3 ( 3 four times)
Since there are 6 students with 4 marks, we have
4, 4, 4, 4, 4, 4 (4 six times)
Add them all up, and divide them by the total amount of students (10) to get
(3+3+3+3+4+4+4+4+4+4)/10=(3*4+4*6)/10=36/10=3.6
Good luck, and feel free to ask questions if you're confused!

Find the difference between the product of 26.22 and 3.09 and the sum of 3.507, 2.08, 11.5, and 16.712
Answers
Final answer:
The difference between the product of 26.22 and 3.09 and the sum of 3.507, 2.08, 11.5, and 16.712 is 47.2208.
Explanation:
The difference between the product and the sum can be found by first calculating the product of 26.22 and 3.09 and then calculating the sum of 3.507, 2.08, 11.5, and 16.712. Once both of these values are calculated, subtract the sum from the product to find the difference.
To calculate the product of 26.22 and 3.09, you would multiply these two numbers:
26.22 × 3.09 = 81.0198
To calculate the sum of 3.507, 2.08, 11.5, and 16.712, you would add these numbers together:
3.507 + 2.08 + 11.5 + 16.712 = 33.799
Finally, to find the difference, subtract the sum from the product:
81.0198 - 33.799 = 47.2208
The difference between the product of 26.22 and 3.09 and the sum of 3.507, 2.08, 11.5, and 16.712 is 47.2208.

Need help what is the answer and what is the equation
Answers
Side note: the equation is already given. There is no need to solve for the variable C
-------------------------------
-------------------------------
Explanation:
We are given 10 degrees Celsius, so C = 10. We will plug this into the given equation. In other words, replace the C with 10. Then use PEMDAS to simplify the right side of the equation
F = (C * 1.8) + 32
F = (10 * 1.8) + 32
F = 18 + 32
F = 50
So 10 degrees Celsius is equivalent to 50 degrees Fahrenheit

The sum of two consecutive integers is at least negative fifteen. What are the smallest values of consecutive integers that will make this true?
Answers
Answer:
x+1 is greater than or equal to -7
Step-by-step explanation:
x is the first integer and x+1 is the next (consecutive) integer.
At least stands for greater than or equal to
x+x+1 is greater than or equal to -15
Subtract 1 from each side
2x is greater than or equal to -16
x is greater than or equal to -8
This means
x+1 is greater than or equal to -7
The smallest values of the integers are: x+1 ≥ -7
What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side).
Parts of an Equation
There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables. As opposed to this, an equation with variables is an algebraic equation.
let the consecutive integers are x and x+1.
So,
x+ (X+ 1)= -15
2x + 1 =-15
2x= -16
x= -8
Hence, x+1 ≥ -7

Write an expression with four terms. Include at least one term with an exponent, one term with a coefficient of 5, one term with three factors, and one constant. Make two of the terms like terms.
Answers
This expression has two terms; 8x³ and 5
The value of '8' in 8x³ is called COEFFICIENT
The value of '3' in 8x³ is called POWER or INDICES
The term 8x³ is called an exponent because it has power/indices
The letter 'x' in the term 8x³ is called VARIABLE
So, we want an expression with four terms
_____ ⁺/₋ _____ ⁺/₋ _____ ⁺/₋ _____
One term with an exponent ⇒ You can choose any letter and any power that will go with it, for example, 6x⁴
One term with a coefficient of 5 ⇒ 5x⁴
One term with three factors ⇒ This could be a combination of any three letters that represent three values for example 'abc'. This term means a × b × c, so it has three factors.
One constant ⇒ Choose any number, say 45
Make two of the terms like terms ⇒ We have 6x⁴ + 5x⁴; these two terms are alike, they are in term of x⁴
Putting the four terms together: 6x⁴ + 5x⁴ + abc + 45
An expression satisfying all the conditions specified is [tex]5x^2 + 5xy + 3xy + 7[/tex]
Here's an expression with four terms that meets all the requirements :
[tex]5x^2 + 5xy + 3xy + 7[/tex]
1. Term with an exponent: [tex]\( 5x^2 \)[/tex] (The exponent is 2)
2. Term with a coefficient of 5: [tex]\( 5xy \)[/tex]
3. Term with three factors: [tex]5xy[/tex] (The factors are 5, x, and y)

One leg of a right isosceles triangle is 8 feet. What is the area of the triangle?
Answers
Step-by-step explanation:
a little late on this answer
The area of a right isosceles triangle with legs each measuring 8 feet is calculated using the formula A = (base x height) / 2, resulting in an area of 32 square feet.
The question you've asked is about finding the area of a right isosceles triangle when one leg is known. In a right isosceles triangle, both legs are of equal length. Since one leg is given as 8 feet, the other leg is also 8 feet. The formula for the area of a right triangle is A = (base x height) / 2.
In this case, the base and height are the same, which are the lengths of the legs of the triangle, so the formula becomes A = (8 feet x 8 feet) / 2. Performing the calculation, we find that A = 64 feet2 / 2, which simplifies to A = 32 feet2. Therefore, the area of the triangle is 32 square feet.
Which statement correctly describes the relationship between the graph of f(x) and g(x)=f(x+2) ?
The graph of g(x) is the graph of f(x) translated 2 units left.
The graph of g(x) is the graph of f(x) translated 2 units up.
The graph of g(x) is the graph of f(x) translated 2 units down.
The graph of g(x) is the graph of f(x) translated 2 units right.
Answers
This is because the +2 is in the parentheses with the x which makes it move left or right and because it’s positive you would do the opposite and more it left
we have that
[tex]f(x)\\g(x)=f(x+2)[/tex]
we know that
the rule of the translation of f(x) to g(x) is equal to
[tex](x,y)----> (x-2,y)[/tex]
that means
the graph of g(x) is the graph of f(x) translated [tex]2[/tex] units left
therefore
the answer is the option
the graph of g(x) is the graph of f(x) translated [tex]2[/tex] units left
Susan and terry run a day care center Since they use susans house it was agreed that her share is twice as Terrys if they earn 225 how much is susans share?
Answers
To determine Susan's share of the daycare earnings, the simple equation T + 2T = 225 was solved to give Terry's share as $75. Susan's share, being double Terry's, is therefore $150.
The total earnings of Susan and Terry together: 2x (Terry's share) + Terry's share = 225
Given that the total earnings are 225:
2x (Terry's share) + Terry's share = 225
3x (Terry's share) = 225
Terry's share = 225/3 = 75
Susan's share = 2 x 75 = 150
Therefore, Susan's share is 150.
Kayla has $500 in her account, and she spends $40 a week on food. If she falls below $30 in her account, she must pay a penalty. What is an inequality that can represent this situation?
Answers
Now we have to compare this somehow to $30. Our inequality is going to look like:
500-40w ? 30
Where the ? is a stand-in for an inequality sign. Which inequality sign should we pick? Take a look at the question and see if you can find any keywords that might give you a hint. "If she falls below" is the big one I'm seeing. If she can't fall below $30, that means she'll always have to stay at or above $30 to avoid paying the penalty. What inequality sign represents at or above?
Final answer:
The inequality that represents this situation is: 500 - 40w < 30, where w represents the number of weeks that have passed.
Explanation:
The situation can be represented by the inequality:
500 - 40w < 30
where w represents the number of weeks that have passed.
This inequality states that the amount of money remaining in Kayla's account (500 - 40w) must be less than $30 for her to have to pay a penalty. If Kayla's account falls below $30, she would have to pay a penalty because she does not have enough money to cover her regular expenses.
For example, if we substitute w = 10 into the inequality, we get 500 - (40 × 10) < 30, which simplifies to 100 < 30. Since 100 is not less than 30, Kayla would not have to pay a penalty.

How to identify the place value of a digit in a number?The place values on the left of the decimal point start as ones, tens, hundreds, and so on. The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths, and so on. The tens mean multiplied by 10. The tenth means the tenth part of that digit which is that digit divided by 10
We are given multiple number names and asked to add them.
We will call d as ones digit, c as tens digit (it get multiplied by 10), b as hundreds digit etc.
We call e as digit at 10th place (division by 10), f as digit at hundredth place and so on.
To find this problem, it will be easier to split the sentences into multiple parts like this;
1. "2 tens" mean 2 x 10 =20
2. "15 ones" mean 15 x 1= 15
Then, if we add them up it will be;
20+15= 35
The answer to this problem would be 35
Therefore, the number that will be equal to 2 tens 15 ones is 35.
