Last week 3/5 of the students in mr.zankers class went on a field trip 7/10 of the students in mr haynes class went what is the average fraction of the students in the two classes who went on the field trip
Answer:
[tex]\dfrac{\dfrac{3}{5}x + \dfrac{7}{10}y}{x + y}[/tex]
where x = number of students in Zankers class and y = number of students in Haynes' class
If the number of students in these classes are equal then the average fraction is 13/20
Step-by-step explanation:
Let x = number of students in Zanker's class
Then number of students who went for the trip is [tex]\dfrac{3}{5}x[/tex]
Let y be the number of students in Haynes' clas
Number of students who went = [tex]\dfrac{7}{10}y[/tex]
Total number of students who went on the trip = [tex]\dfrac{3}{5}x + \dfrac{7}{10}y[/tex]
Total number of students in both classes = x + y
So average fraction
=
= [tex]\dfrac{\textsf {Total Number of Students On Trip}}{\textsf {Total Number of Students}}\\\\= \dfrac{\dfrac{3}{5}x + \dfrac{7}{10}y}{x + y}[/tex]
Without knowing how many students are in each class we can only come up with an equation
If we assume the same number of students in each class
Then we get total students who went on trip = [tex]\dfrac{3}{5} N + \dfrac{7}{10}N[/tex][tex]= \left( \dfrac{3}{5} + \dfrac{7}{10}\right)N= \left(\dfrac{13}{10}\right)N[/tex]
where N = total number of students
Since the total in 2 classes is 2N the average fraction
[tex]= \left(\dfrac{13}{10}\right)N \div 2N = \dfrac{13}{20}[/tex]
Find all the integer solutions of each system of inequalities.
The integer solutions of the system of inequalities are x >= 1 and b <= 0
What are inequality expressions?Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal
What are the integer solutions of the system of inequalities expressions?System of inequalities 1
Here, we have
3 - 18x < 0
0.2 - 0.1x > 0
Rewrite as
0 < 0.2 - 0.1x
The above means that
3 - 18x < 0.2 - 0.1x
Collect the like terms
So, we have
3 - 0.2 < 18x + 0.1x
Evaluate the like terms
So, we have
2.8 < 18.1x
Divide both sides by 18.1
So, we have
0.155 < x
Rewrite as
x > 0.155
The integer value greater than 0.155 is at least one
Hence, the integer solution of the system is x >= 1
System of inequalities 2
Here, we have
6 - 4b > 0
3b - 1 > 0
The above means that
6 - 4b > 0 < 3b - 1
Collect the like terms
So, we have
-4b > - 6 + 0 + 1< 3b
Evaluate the like terms
So, we have
-4b > -5 < 3b
Solve for b
b < -1.25 or -1.67 < b
The integer values in this case are 0
So, we have
b <= 0
Hence, the integer solution of the system is b <= 0

The value of the z-score for the sample mean is estimated as 0.5.
What is meant by the term z-score?A Z-score is a statistical assessment that explains a value's relationship to a mean of a group of values. The Z-score is measured in aspects of standard deviations from a mean. A Z-score of zero indicates that the information point's score is the same as the mean score.As per the stated question;
The formula for calculating the z-score is;
z = (x - μ)/σ
x = sample size
μ = population mean
σ = standard deviation population.
The vales given in the question;
μ = 25σ = 20x = 35Substitute the value in the z-score.

What is the measure of an exterior angle of a regular octagon?
(Read carefully)
The measure of an exterior angle of a regular octagon is 45 degrees
What are angles?Angles are formed when two or more lines intersect.
This in other words means that angles is the measure of space between the intersection of rays or lines
How to determine the measure of the exterior angle?The given parameters are:
Shape: regular octagon
A regular octagon has 8 sides, and the total sum of angles is 360
So, we have
Exterior angle = Total sum of angles/Number of sidee
This gives
Exterior angle = 360/8
Evaluate the quotient
Exterior angle = 45
Hence, the measure of the angle is 45 degrees

Expand and simplify (x+3)(2x-1)(x+4)
The expansion and simplified form of the expression [(x+3)(2x-1)(x+4)] will be (2x³ + x² - 25x - 12).
As per the question statement, we are provided with the expression of [(x+3)(2x-1)(x+4)] where three separate factors of the variable "x" are multiplied with each other.
We are required to expand and simplify the above-mentioned expression to obtain our desired answer.
Given, [(x + 3)(2x - 1)(x + 4)]
= [{(x + 3)*(2x - 1)}(x + 4)]
= [{(x*2x) - (x*1) + (3*2x) - (3*1)}(x + 4)]
= [(2x² - x - 6x -3)(x + 4)]
= [(2x² - 7x -3)(x + 4)]
= [(2x²*x) + (2x²*4) - (7x*x) - (7x*4) - (3*x) - (3*4)]
= [2x³ + 8x² - 7x² - 28x - 3x - 12]

What are Angles?When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.
Given that,
HL is perpendicular to HJ
m ∠2 = (a + 15)°
and
m ∠3 = (a + 35)°
If HL and HJ are perpendicular,
Then,
m ∠2 + m ∠3 = 90°
(a + 15)° + (a + 35)° = 90°
Now, solve for a
(a + 15)° + (a + 35)° = 90°
a + 15 + a + 35 = 90
a + a = 90 - 15 - 35

question the radius of a circle is decreasing at a constant rate of 0.1 centimeter per second. in terms of the circumference c, what is the rate of change of the area of the circle, in square centimeters per second?
The rate of the area of the circle, expressed in terms of the circumference C, is 0.1C square centimeters per second.
What is known as a circle?
A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.C=2πr
A=πr²
dA/dr=2πr=C
dr/dt=-0.1 cm/sec
dA/dt
= dA/dr * dr/dt
= 2πr (-0.1) cm²/s
= -0.1C cm²/s
As a result, a circle's radius is reducing at a steady rate of 0.1 centimeters each second. The rate of the area of the circle, expressed in terms of the circumference C, is 0.1C square centimeters per second.

The coordinates of Z are (-11.5, 5)
What is section formula?When a point on a line segment divides it into two segments, the formula used to determine the coordinates of that point is known as the section formula. Let us say, we have a point P(x,y) that divides the line segment with marked points as A (x1,y1) and B(x2,y2). To find the coordinates, we use the section formula, which is mathematically expressed as:
P(x, y) = (m[tex]x_2[/tex] + n [tex]x_1[/tex] / m+ n, m [tex]y_2[/tex] +n[tex]y_1[/tex] /m+ n)
Given coordinates:
XY:XZ is 2:3
X is located at (6,10) and Y is located at (-1,8).
let the coordinates of Z(x, y)
using section formula
-1 = (2x + 18)/ 5

The perimeter of each pool is 92 ft.
What is perimeter?
A perimeter is a closed route that covers, surrounds, or outlines a two-dimensional form or length. The circumference of a circle or an ellipse is its perimeter.
Given, the triangles are congruent so,
20x-15 = 15x+15
=> 20x-15x = 15+15
=> 5x = 30
=> x = 30/5 = 6
Therefore, perimeter = (4x-4) + (5x+1) + 41
= (4x6 - 4) + (5x6 + 1) + 41
= 20 + 31 + 41
