First, we need to know the number that chose vanilla flavor
Total number of classmate = 300
percentage of those that love Vanilla = 100% - 14% - 42% - 18% = 26%
Number of people that love Vanilla = 26% of 300 =
[tex]=\frac{26}{100}\times300[/tex][tex]=78[/tex]Next, find the number of those that chose strawberry
Number of people that love Strawberry = 18% of 300
[tex]=\frac{18}{100}\times300[/tex][tex]=54[/tex]
The number that chose vanilla than strawberry is 78 - 54= 24
Consider the following mapping:(a)948546Part A:Write a set of ordered pairs to represent the mapping.
For order pair
In the first block the value 9 maps to 4 So, (9,4)
The value 8 maps to 4 & 6 so, the pair is (8,4) & (8,6)
The value 4 maps to 5So, (4,6)
The order pairs are (9,4), (8,4) (8,6) & (4,5)
b) Domain are the set of input values
In this mapping the first block map to the second thus, the value at the first block is the initial valua and act as domain of the mapping
So, the Domain = {9,8,4}
c) Range is the set of all the possible outputs
In this mapping, the second block show the final values of the function, thus the second block act as a range of the mapping
So, the Range= {4,5,6}
d) The mapping doesnot represent the function as the mapping is not one-one
A function must staisfy one-one rulei.r for every value of domain thier exists only one value of range
Where in this mapping we have, the range 4 whose domain are 9 & 8 does they donot satisfy the one-one creteria hence they are not one-one and niether they are function

4) The capacity of a bathtub is 297 liters. The capacity of a sink is 9 liters, How many sinks of water will fill the bathtub? A 2,673 B 30 33 5) There are 354 milliliters of soda in each can. How much soda is there in cans? A 59 L B 2 L 124 mL © 360 L Short Answer Write the answer in the space given.
We are told that one can of soda has a capacity of 354 milliliters, then in order to calculate how much soda is there in 6 cans, we just have to multiply 354 mlliliters by 6, then we get:
Soda in 6 cans = 354 × 6 = 2124
We can split these 2124 milliliters as 2000 milliliters+ 124 milliliters.
1 liter is equivalent to 1000 milliliters, then we can convert the first 2000 milliliters to liters by dividing by 1000, then we get:
soda in 6 cans = 2000 ÷ 1000 liters + 124 milliliters
soda in 6 cans = 2 liters + 124 milliliters
Then, the amount of soda in 6 cans is 2liters 124milliliters, the correct answer is option B

The function f(x) = x³ - 2x is an odd function.
From the question, we have
f(x) = x³ - 2x,
The function to be odd if f(-x) = -f(x)
put x = -x in the function,
f(-x) = (-x)³ - 2(-x)
f(-x) = -x³ + 2x
Therefore, the function f(x) = x³ - 2x is an odd function.
Multiplication:
Mathematicians multiply the numbers to find the sum of two or more. It is a fundamental mathematical operation that is frequently employed in daily life. When we need to combine groups of similar sizes, we multiply. The fundamental concept of repeatedly adding the same number is represented by multiplication. The product of two or more numbers is the result of the multiplication of the factors, which are the amounts being multiplied. It is easier to repeatedly add the same number when the numbers have been multiplied.

Use arguments based on the Pythagorean theorem, its converse, and similar triangles to show that a triangle with sides 5n, 12n, and 13n is a right triangle. HINT: Start with n= 1, which results in side lengths of 5, 12, and 13. Answer in complete sentences and include all relevant calculations and algebraic manipulations
Sides:
5n
12n
13n
If n is 1 the triangle have sides: 5, 12, 13
The converse of the pythagorean theorem is: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle:
[tex]\begin{gathered} 13^2=12^2+5^2 \\ 169=144+25 \\ 169=169 \end{gathered}[/tex]Then, a triangle with sides 5, 12, 13 is a right triangle.
If n is 2 the triangle have sides: 10,24, 26
converse of the pythagorean theorem:
[tex]\begin{gathered} 26^2=24^2+10^2 \\ 676=576+100 \\ 676=676 \end{gathered}[/tex]Triangle with n=1 and n=2 are similars as the ratio between corresponding side is equal:

Similar triangles have different sizes but the correpondign angles are the same (are congruent).
As triangles with sides 5n, 12n, 13n are similar triangles (All of then have the same measure on his correspondig angles) and makes true the Pythagorean theorem, they are right triangles.
Given the following rule, describe the transformation. (x , y) ---> (x + 9, y - 2)
The given rule is
[tex](x,y)\to(x+9,y-2)[/tex]The transformations shown indicate translations if the original point.
Any value (k) added/subtracted to the x-coordinate of a point results in a horizontal movement.
If the value is added to the x-coordinate → the resulting movement is k units to the rigth.
If the value is subtracted to the x-coordinate → the resulting movement is k units to the left.
Any value (m) added/subtracted to the y-coordinate of a point results in a vertical movement.
If the value is added to the y-cordinate → the resulting movement is m units up.
If the value is subtracted to the y-coordinate → the resulting movement is m units down.
In the given rule, 9 units are added to the x-coordinate, which indicates a translation 9 units to the right.
And there are 2 units subtracted to the y-coordinate, which indicates a translation 2 units down.

A motorboat travels 200 miles in 5 hours going upstream. It travels 260 miles going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current?
B= Speed of the boat in the water =46 miles per hour
A= Speed of the Current =6 miles per hour
Speed upstream: B-A
Speed Downstream: B+A
Distance= Speed x time
Upstream :
(B-A) 5 = 200
Downstream:
(B+a) 5 = 260
Simplify both equations:
5B-5A =200
5B+5A =260
Add both equations:
10B = 460
Solve for B
B= 460/10
B= 46 miles/hour
Replace B on any distance equation:
5B-5A =200
5(46)-5A=200
Solve for A
230-5A=200
230-200=5A
30=5A
30/5 =A
A= 6 miles/hour
Tom goes fishing with Jason. Tom catches five trout and four catfish. Jason catches twice as many trout as Tom did. How many trout did Jason catch?
We know that Tom catches five trout and four catfish and we also know that Jason catches twice as many trout as Tom did.
Knowing that Jason catches twice as many trout as Tom did we must multiply the number of trouts that Tom caught (5 trouts) by 2
[tex]5\cdot2=10[/tex]So, Jason caught 10 trouts.
x = 8 is a solution for equation 3x = 27 true or false
ANSWER
False
EXPLANATION
The guven equation is:
3x = 27
For x to be a solution of the equation, the value of x must be such that the left and right hand sides of the equation must match.
So, for x = 8:
3(8) = 27
24 = 27
As we can see, the two sides do not match, so x = 8 is not a solution.

choose the fraction pair that is equivalent. 3/4 and 4/3, 4/5 and 8/20, 8/24 and 1/3, or 3/12 and 1/3
To find out if two fractions are equivalent or not, we multiply by a cross. That is, multiply the numerator of the first fraction with the denominator of the second fraction and multiply the denominator of the first fraction with the numerator of the second fraction and check that it gives us the same result. For example:

[tex]\frac{8}{24}\text{ and }\frac{1}{3}[/tex]Solve the inequality for A:-3 (9 – 4A) > 3 (2A – 11).
Given the inequality

A rectangular room is 5 meters longer than it is wide, and its perimeter is 30 meters. Find the dimension of the room
The dimensions of the rectangular room is 10 meters and 5 meters respectively.
What is the dimensions of the room?The perimeter of a rectangle = 2(length + width)
Let
Width of the room = w metersLength of the room = (w + 5) metersPerimeter of the room = 30 metersThe perimeter of the rectangular room = 2(length + width)
30 = 2{(w + 5) + w}
30 = 2(w + 5 + w)
open parenthesis
30 = 2w + 10 + 2w
collect like terms
30 - 10 = 4w
20 = 4w
divide both sides by w
w = 20/4
w = 5
Hence,
Width of the room = w meters
= 5 meters
Length of the room = (w + 5) meters
= (5 + 5)
= 10 meters
Therefore, the length and width of the room are 10 meters and 5 meters respectively.

The box plot shows the distribution of the data classified in quartiles.
If we want to know about the mean of the data set, we can only that it will be located within the range of the data set.
It will be closer to the median as the distribution gets less skewed.
By looking at the box plot, we can not confirm that April's mean is higher than October's mean, as the plots are overlapped.
We can not also concluded about the relation between the spread of the data and the relation with the mean.
