If a female student is selected at random, find the
probability that the student is a senior.
P(Senior | Female ) = [ ? ]%
Round to the nearest whole number.
Answer:
19%
Step-by-step explanation:
You want the probability a student is a senior, given that they are female.
TableThe table indicates that 3 +4 +6 +3 = 16 students are female. Of those, 3 are seniors. The desired probability is ...
P(senior | female) = N(senior & female)/N(senior) = 3/16 = 0.1875
The probability that a female student is a senior is about 19%.

The number of integers between 1 and 2022 inclusive that are multiples of 11 but not multiples of 3 is
The number of integers between 1 and 2022 inclusive that are multiples of 11 but not multiples of 3, using arithmetic sequences, is of:
122.
What is an arithmetic sequence?An arithmetic sequence is a sequence of values in which the difference between consecutive terms is constant and is called common difference d.
The nth term of an arithmetic sequence is given by the rule presented as follows:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term of the arithmetic sequence.
The sequence composed by the integer multiples of 11 between 1 and 2022 are given as follows:
(11, 22, ..., 2013)
The first term and the common ratio of the sequence are given as follows:
[tex]a_1 = 11, d = 11[/tex]
The number of terms is obtained as follows:
2013 = 11 + 11(n - 1)
11n = 2013
n = 2013/11
n = 183.
The sequence composed by terms that are multiples of 11 and of 3 is given by:
(33, 66, ..., 2013).
The first term and the common ratio of the sequence are given as follows:
[tex]a_1 = 33, d = 33[/tex]
The number of terms is obtained as follows:
2013 = 33 + 33(n - 1)
33n = 2013
n = 2013/33
n = 61.
Hence the number of integers that are multiples of 11 but not 3 is given by:
183 - 61 = 122.

how much of brand A fruit punch (20% fruit juice) must be mixed with 9 L of brand b fruit punch (40% fruit juice) to create a mixture contains 32% fruit juice ?
6 liters of brand A fruit punch must be mixed with 9 L of brand b fruit punch.
Let x=liters of Brand A fruit punch to be mixed with 9 liters of Brand B fruit punch.
x + 9 = liters of mixture.
20%(x) + 9*40% = 32%(x+9)
20/100 x + 9*40/100 = 32/100 (x+9)
0.2x + 360/100 = 0.32x + 9*0.32
0.2x + 3.6 = 0.32x + 2.88
0.12x = 3.6 - 2.88
0.12x = 0.72
divide by 0.12 on both sides
x = 0.72/0.12
= 72/100/12/100
= 72/12
= 6 liters.
Therefore 6 liters of brand A fruit punch must be mixed with 9 L of brand b fruit punch.

The will be A'(0, 20), B'(20, 10) and '(-10, 0). Transformation is the of a point from its to a. Types of transformation are reflection, translation, rotation and dilation.
What is transformation?
When a function is transformed, the graph's curve either "moves to the left/right/up/down," "expands or compresses," or "reflects." For instance, by simply moving the graph of the function g(x) = x2 up by 3 units, the graph of the function f(x) = x2 + 3 is obtained. Function transformations are very useful for graphing functions without having to start from scratch because they allow you to move, expand, compress, or reflect the curve. In this article, we will examine the guidelines for function transformations as well as examples of how to transform various function types.
Let ABC be a with coordinates A(0, 2), B(2, 1), C(-1, 0).
The coordinate of points A, B, C will change by below rule
(x, y)↔(10x, 10y)
where 10 is the scale factor.
∴A(0, 2) ↔A'(0, 20)
B(2, 1) ↔B'(20, 10)
C(-1,0) ↔C'(-10, 0)
Hence, will be A'(0, 20) ,B'(20, 10) and C'(-10, 0)

Rewrite the given expression as follows
This is represented using
(30 + 45)
Factor out 5 from the expression
So, we have the following representation
30 + 45 = 5(6 + 9)
The above means that 5 is the GCF of the sum expression 30 + 45
This represents the GCF

What is Division?A division is a process of splitting a specific amount into equal parts.

Sum and Product of Two Numbers Find two numbers whose sum is 20 and whose product is the maximum possible value. (Hint: Let x be one number. Then 20 - x is the other number. Form a quadratic function by multiplying them, and then find the maximum value of the function.)
Answer:
The numbers are 10 and 10Step-by-step explanation:
As described in the hint:
the numbers are x and 20 - x, their product is maximum possible value.The product is:
x(20 - x) = - x² + 20xThis is a quadratic expression ax² + bx + c with the leading coefficient of a = - 1, b = 20 and c = 0.
It has a maximum and no minimum value since a < 0.
The x-coordinate of the maximum is the vertex which is x = - b/2a.
The x- coordinate of the vertex is:
x = - 20/-2 = 10The maximum value itself is:
- 10² + 20*10 = - 100 + 200 =100Answer:
10 and 10.
[tex]f(x)=-x^2+20x[/tex]
Maximum value of the function is 100.
Step-by-step explanation:
Two numbers whose sum is a positive integer, and whose product is the maximum possible value have to be two positive integers.
Pairs of positive integers whose sum is 20:
1 and 192 and 183 and 174 and 165 and 156 and 147 and 138 and 129 and 1110 and 10The pair of numbers whose product is the maximum possible value is the pair of numbers that are closest to each other.
Therefore the pair of numbers is 10 and 10:
[tex]\implies x = 10[/tex]
[tex]\implies 20 - x = 10[/tex]
Form a quadratic function by multiplying:
[tex]\implies f(x)=x(20-x)[/tex]
[tex]\implies f(x)=20x-x^2[/tex]
[tex]\implies f(x)=-x^2+20x[/tex]
The maximum value of the function is the y-value of its vertex.
[tex]\boxed{\begin{minipage}{5.6 cm}\underline{Vertex form of a quadratic equation}\\\\$y=a(x-h)^2+k$\\\\where:\\ \phantom{ww}$\bullet$ $(h,k)$ is the vertex. \\ \phantom{ww}$\bullet$ $a$ is some constant.\\\end{minipage}}[/tex]
To convert the function to vertex form, complete the square.
Factor out negative 1:
[tex]\implies f(x)=-(x^2-20x)[/tex]
Add and subtract the square of half the coefficient of the term in x:
[tex]\implies f(x)=-\left(x^2-20x+\left(\dfrac{-20}{2}\right)^2-\left(\dfrac{-20}{2}\right)^2\right)[/tex]
[tex]\implies f(x)=-(x^2-20x+100-100)[/tex]
[tex]\implies f(x)=-(x^2-20x+100)+100[/tex]
Factor the perfect square trinomial:
[tex]\implies f(x)=-(x-10)^2+100[/tex]
Therefore, the vertex of the function is (10, 100), and so the maximum value of the function is 100.

In the first week of July,1,020 a record people went to the local swimming pool. In the second week, 125 fewer people went to the pool than in the first week. In the third week, 145 more people went to the pool than in the second week. In the fourth week, 175 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
The percent decrease in the number of people who went to the pool over these four weeks is 15.2%.
How to calculate the percentage?The change regarding the people at the swimming pool for the number of weeks will be:
= 1020 - 125 + 145 - 175
= 865
The initial number of people is 1020.
Therefore, the percentage decrease will be:
= Decrease in number / Initial number × 100
= (1020 - 865) / 1020 × 100
= 155/1020 × 100
= 15.2%
The Percentage is 15.2%.
