HYRIGH fararefant et fanter i In a class of 25 student,
17 like volleyball, 15 like basketball and 10 like both games.
Illustrate it with a Venn-diagram and find the number of
students who don't like any of the games. (Ans: 3]
Answers
Given:
Total students in a class = 25
Students who like volleyball = 17
Students who like basketball = 15
Students who like both = 10
To find:
The students who don't like any of the games.
Solution:
We have,
Total students in a class = 25
Students who like volleyball = 17
Students who like basketball = 15
Students who like both = 10
Now,
Students who like only volleyball = 17-10
= 7
Students who like only basketball = 15-10
= 5
Students who don't like any of the games is the difference of total number of students and number of students who like at least one game.
Students who don't like any of the games = 25 - (7+5+10)
= 25 - 22
= 3
Therefore, 3 students don't like any of the games.

Express f(1) = log(100)
= log( 200 ) in the general form of a logarithmic function
g(x) = k + a log b(x – h).
Answers
a= -3
b= 1
k = 2
h= 0
refer to the attachment
The logarithmic equation f(x) = log(100) in the form g(x) = k + a log b(r – h) is f(x) = 0 + 2log(10 - 0)
What is logarithmic equation?In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number x to the base b is the exponent to which b must be raised, to produce x. For example, since 1000 = 10³, the logarithm base 10 of 1000 is 3, or log₁₀ = 3.
Here, we have,
to rewrite the logarithmic equation:
The equation is given as:
f(x) = log(100)
Express 100 as 10^2
f(x) = log(10^2)
Apply the law of logarithm
f(x) = 2log(10)
Subtract 0 from 10
f(x) = 2log(10 - 0)
Add 0 to the equation
f(x) = 0 + 2log(10 - 0)
Hence, the logarithmic equation f(x) = log(100) in the form g(x) = k + a log b(r – h) is f(x) = 0 + 2log(10 - 0)

Emil is cutting a 72-inch-long board and a 54 in long board into shelving. He wants to make as many shelves as he can while using up all the wood. What is the longest possible length of the shelves?
Answers
Answer: The longest possible length of the shelves = 18 inches
Step-by-step explanation:
Given: Lengths of two boards are 72-inches and 54 inches.
To make as many shelves as he can while using up all the wood we will find the longest possible length of the shelves = HCF ( 72, 54)
72 = 2 x 2 x 2 x 3 x 3
54 = 2 x 3 x 3 x 3
HCF(72,54) = 2 x 3 x 3 = 18
Hence, the longest possible length of the shelves = 18 inches

An electrician earns $110 after his first hour of working for a client. His total pay based on the number of hours worked can be represented using the sequence shown.
110, 130, 150, 170, ...
Which recursive formula can be used to determine the total amount of money earned for each successive hour worked based on the amount of money currently earned?
f(n + 1) = f(n) + 20
f(n + 1) = f(n) + 110
f(n + 1) = f(n + 1) + 20
f(n + 1) = f(n + 1) + 110
Answers
Answer:my guess would be A because B and D there was already a start-up salary of 110$, but it could be c, i just wanted to choose the simplest answer choice.
Step-by-step explanation: it just makes sense that it is not B or D
The recursive formula that could be used for measuring the total amount of money is f(n+1) = f(n)+20.
What is a recursive formula?A recursive is a type of function or expression stating some concept or property of one or more variables, which is specified by a procedure that yields values or instances of that function by repeatedly applying a given relation or routine operation to known values of the function.
Given that,
The electrician earns $110.
And the sequence should be 110, 130, 150, 170, and so on.
Here we assume that f(x) represent pay.
And x be the number of hours worked.
Based on the above information, we can see that there are 20 increments in every next number.
So, the equation should be f(n+1) = f(n)+20
hence, the recursive formula that could be used for measuring the total amount of money is f(n+1) = f(n)+20.

After Cynthia microwaves her bowl of morning porridge, it is either too cold, just right, or too hot. She estimates there is a 35% chance that it will be too cold and a 50% chance that it will be too hot. What is the probability that Cynthia's morning porridge will be just right
Answers
The probability Cynthia's porridge is just right is 15%.
A probability describes how likely is for an event to occur. Probabilities can be expressed using different but one of the most common ways to express probability is to use percentages or 0% to 100%.
Moreover, in some cases, the probability of an event occurring is directly related to the probability of another event. For example, if Cynthia porridge is hot, it means it is neither right nor cold.
Based on this, we can calculate the probability of one event by adding the probabilities of other events and subtracting the result to 100% (total events).
35% (probability the porridge is cold) + %50 (probability the prorridge is hot) = 85%100% - 85% = 15% (probability the porridge is neither hot nor cold or that the porridge is just right).

5. You are scheduling your classes for next year. There are 4 required classes: a physical education
class, a history class, an english class, and a math class. You can choose from 5 physical education
classes, 6 history classes, 5 english classes, and 3 math classes. In how many different ways could
you select the 4 required classes?
Answers
==============================================
Explanation:
For now, let's consider we can only select 2 classes instead of 4. Let's say we only had to worry about PE and history.
Let A,B,C,D,E represent the five PE classes.
Let F,G,H,I,J,K represent the six history classes.
If you arrange the letters in a table, you should get 5*6 = 30 different inner boxes of the table. Refer to the diagram below.
Each two letter code in the table represents the 2 class combo. For example, BG means you picked PE class B and history class G.
This idea can be extend to selecting 3 classes. Imagine that each of the codes in the table are laid along the side of a new table. So we'd have a table of 30 rows. Then lay out 5 columns (say with letters L,M,N,O,P) to represent the 5 English classes. You would get a table of 30*5 = 150 different combos here. Of course you shouldn't actually make such a table since it's so large, but I'm simply just saying for you to imagine one. All of the tables mentioned are completely optional. A tree diagram is another way to organize things, though tree diagrams tend to get cumbersome.
Anyway, we would have 5*6*5 = 30*5 = 150 different ways to pick the PE, history and English classes. We can extend this out to include the math classes as well.
-------------------------
In short, all we do is multiply the given values together:
5*6*5*3 = 30*15 = 450
This idea is known as the counting principle.

Maggies brother is 7 years younger than twice here. The sum of their ages i 32
How old is Maggie
Maggie is
Years old
Answers
Then,
According to the question
Maggies brother is 7yrs younger than twice of her so, the equation will be ,
2x-7=y………eqn 1
And the sum of their ages is 32 so,
x + y = 32 ………..eqn 2
Now,
Putting the value of y in equation 2 we get,
x + y= 32
x + (2x-7) =32
x + 2x-7 =32
3x = 32+7
x = 39/3
x = 13
Here,
Taking eqn 2 and putting the value of x we get,
x + y = 32
13 + y = 32
Y = 32-13
y = 19
Hence,
The age of maggies is 13 years
Answer:
Maggie is 13years old
Step-by-step explanation:
Let the age of Maggie be = x
Let her brothers age be = y
Given:
Brother is 7 years younger than twice her age , y = 2x - 7 --------- ( 1 )
[ Twice her age = 2x
7 years younger than twice her age = 2x - 7 ]
Sum of their ages , x + y = 32 -------- ( 2 )
Substitute ( 1 ) in ( 2 ) :
x + ( 2x - 7 ) = 32
x + 2x - 7 = 32
3x = 32 + 7
3x = 39
x = 13
Maggie's age = 13 years
Substitute x in ( 1 ) :
y = 2x - 7
= 2 ( 13 ) - 7
= 26 - 7
= 19
Brother's age = 19 years

A three-dimensional figure has symmetry about an axis if there is a line about which the figure can be rotated by an angle greater than 0∘ and less than 360∘ so that the image coincides with the preimage.So, the given figure has symmetry about seven axes.
Therefore, the figure has plane symmetry and symmetry about an axis.
