The relative frequency of all students surveyed who go to Cook Middle School and prefer Energy flow is 57%.
What is relative frequency?This refers to how many times a particular type of occasion takes place within the total number of observations. This type of frequency uses percentages, fractions, and proportions.
Formula for calculating Relative Frequency:
Relative Frequency = Count of event
Total number of Observation
From the question:
No of students that like Gym Juice in Elim School =5
No of students that like Energy Flow in Elim School =10
Total Number of students in Elim School =15
No of students that like Gym Juice in Cook Middle School =15

a rectangular garden has a length that is six feet more than twice its width. it takes 120 feet of fencing to completely enclose the garden's area. write an equation that could be used to find the width of the garden. clearly define your variable.
Length (L) = 42
Width (W) = 18
and the equation which helps to find the width of the garden is
L = 6 + 2W
Now, we have to find the length and width of the garden area.
It is given that,
we know that the Length is 6 feet more than twice the width, this in other words, it means that:
L = 6 + 2W -------------------------(1)
So, let's denote W as X
The perimeter of the garden is 120 and the expression to calculate is:
P = 2W + 2L ------------------------(2)
Replacing all the values in the above expression we have the following:
120 = 2x + 2(6 + 2x) ---------------------(3)
Solving for x from the above equation (3), we have:
⇒120 = 2x + 12 + 4x
⇒120 - 12 = 6x
⇒108 = 6x
⇒x = 108/6
⇒ x = 18
So the Width is 18, therefore the Length from equation (1):
L = 6 + 2(18)
⇒L = 6 + 36
⇒L = 42

Find the equation of the parabola with the given x-intercepts and point on the graph. Use y = a(x-p)(x-q).

Answer:
y = -2/7(x + 4)(x - 7)=============================
Givenx- intercepts (-4, 0) and (7, 0),Point P (3, 8).SolutionThe given translates as:
p = -4, q = 7, x = 3, y = 8Use given x - intercepts to get the equation:
y = a(x + 4)(x - 7)Use the coordinates of P to find the value of a:
8 = a(3 + 4)(3 - 7)8 = a*7*(-4)8 = - 28aa = 8 / - 28a = - 2/7The equation of this parabola is:
y = - 2/7(x + 4)(x - 7)Answer:
[tex]\textsf{Intercept form}: \quad y=-\dfrac{2}{7}(x+4)(x-7)[/tex]
[tex]\textsf{Standard form}: \quad y=-\dfrac{2}{7}x^2+\dfrac{6}{7}x+8[/tex]
Step-by-step explanation:

If the x-intercepts are (-4, 0) and (7, 0) then:
p = -4q = 7Substitute the values of p and q into the formula:
[tex]\implies y=a(x-(-4))(x-7)[/tex]
[tex]\implies y=a(x+4)(x-7)[/tex]
To find a, substitute the given point on the curve P (3, 8) into the equation:

[tex]\implies 8=a(7)(-4)[/tex]
[tex]\implies 8=-28x[/tex]

A group entering a zoo purchased 32 admission tickets for a total of $148. Adult tickets cost $7. 50, and tickets for children cost $3. 50. How many of each type of ticket were purchased?.
23 tickets are purchased for children and 9 tickets are purchased for adults.
Given,
In the question:
A group entering a zoo purchased 32 admission tickets for a total of $148. Adult tickets cost $7. 50, and tickets for children cost $3. 50.
To find the how many of each type of ticket were purchased?
Now, According to the question:
It is given in the question that 32 tickets are purchased by group which cost total $148.
Let the number of children of the group who are entering the zoo be x. Then the number of adults will be 32- x
Now cost of one ticket for adult = $7.50
Total amount spent on adult tickets = 7.50 × (32-x)
Similarly, cost of one ticket for child= $3.50
Total amount spent on children tickets = 3.50 × x =3.5x
Total amount spent by group on tickets = $148
⇒ 7.5 × (32-x) + 3.5x = 148
⇒ 240 - 7.5x + 3.5x = 148
⇒ 7.5x - 3.5x = 240 - 148
⇒ 4x = 92
⇒ x = 23
Children = 23
Adults = 32-x = 32-23 = 9
Hence, 23 tickets are purchased for children and 9 tickets are purchased for adults.

XZ=
The length of the line YZ is 26 units
The Y is the mid point of the line XZ
The length of the line XY = 20 + 2a
The length of the line YZ = 8 + 6a
When Y is the mid point of the line XZ, then the length of the line XY is equal to the length of the line YZ

2. Triangle BIG is similar to triangle CAT. If BG is 6 units and CT is 15 units, then what is the length of IG if At is 20 units?
3. Quadrilateral SMAK is similar to quadrilateral DOWN. Assuming the length of SM is 34u and the length of DO is 17u, what is the ratio of AK to WN in simplest form?
1) the speed of Simon per hour is 128 miles/Hr
2) The length of IG is 20 Units.
3) The ratio of SM is 2:1
What is the explanation of the above answer?1) For 1, to obtain the speed of Simon per hour, all you need to do is multiply 32 x 4.
This is because in every hour, 15 minutes occurs four times. That is:
1 hour = 60 minutes
Hence, if 32 miles is done in 15 minutes, then 60 minutes =
32 x 4
= 128 miles
Hence the speed of Simon per hour is 128 Miles/ Hour
2) Given that the two triangles are identical, it means that on the basis on RHS theorem we have been given all the sides. Note that BG is 6 Units (we are assuming that this is the base) , then AT from the other triangle (see attached) is 20.
We assume this is the Hypotenuse. CT is also given. We assume this is the height. If we have CT and AT, and both triangles are the same, then IG is 20 units.
3) For the quadrilateral, recall that in quadrilaterals opposite sides are equal. If one side is 34u on one, and the other side is 17u on the other quadrilateral, then we already have the measure of the sides for both quadrilaterals.
So the Ratio of AK to WN

Initial height of plant = 6 3/8 inches
