Answer:
39
Step-by-step explanation:
37 = 96 %
x = 100%
[tex]x =\frac{37(100)}{96} =38.54= 39[/tex]
[tex]\huge\boxed{39\ \text{students}}[/tex]
Note: The numbers in this problem are a little weird and don't work out perfectly. I'll demonstrate at the end of this answer how something seems a little off in the problem, but we'll get as close as possible.
SolvingWe know from the problem that 37 students are equal to 96% of the class.
Let's write this as an equation:
[tex]37=0.96x[/tex]
Divide both sides of the equation by [tex]0.96[/tex] to isolate [tex]x[/tex].
[tex]38.54\approx x[/tex]
We'll round this to [tex]39[/tex] as the final answer.
Why this doesn't seem quite rightIt's important to note that you can't have partial students, only whole numbers.
If we do the math here, 37 out of 39 students is about 95%.
Also, 37 out of 38 is about 97%.
I'm not sure how the original writer of the question got 96%, but I suppose 39 is the best answer with what's been given.

Answer:
6/5 or 1.2, they're the same value
Step-by-step explanation:
When it says "rate of change", it's really just asking for the slope. If you don't know what the slope is, essentially how much the y-value increases by whenever x increases by 1. This can be formally defined using the equation: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] which is essentially [tex]\frac{rise}{run}[/tex]. The subtraction is finding the difference between the two numbers to see how much it's changed by. Btw the order doesn't matter, I could plug in (-3, -2) as (x2, y2) or I could plug it in as (x1, y1) as long as I make sure to input it in correctly. In this example I'll just say (-3, -2) = (x1, y1) and (2, 4) = (x2, y2). Plugging these values into the equation gives you: [tex]\frac{4- (-2)}{2- (-3)} = \frac{6}{5}[/tex] that's the rate of change

The quadratic equation is y = 1/2x^2 - 3x + 4
How to determine the equation?A quadratic equation is represented as:
y = ax^2 +bx + c
Using the values on the table, we have:
a(0)^2 + b(0) + c = 4 ---- when x = 0
a(2)^2 + b(2) + c = 0 ---- when x = 2
a(4)^2 + b(4) + c = 0 ---- when x = 4
Evaluate these equations
c = 4
4a + 2b + c = 0
16a + 4b + c = 0
Substitute c = 4
4a + 2b + 4 = 0
16a + 4b + 4 = 0
Divide through by 2 and 4
2a + b + 2 = 0
4a + b + 1 = 0
Subtract both equations
2a -1 = 0
Solve for a
a= 1/2
Substitute a= 1/2 in 4a + b + 1 = 0
4 * 1/2 + b + 1 = 0
Evaluate
2 + b + 1 = 0
Solve for b
b = -3
So, we have:
y = ax^2 +bx + c
This gives
y = 1/2x^2 - 3x + 4
Hence, the quadratic equation is y = 1/2x^2 - 3x + 4

We can find the graph by finding the roots of the equation.
Since the equation is already in factored form, we can use the Zero Product Property to find the roots. The roots of an equation are the value(s) of x when y is 0 (x-axis).
Find the Rootsy = (x - 2)(x - 3)0 = (x - 2)(x - 3)0 = (x - 2)The roots of the equation are 2 and 3. That means the graph intersects the x-axis at points 2 and 3. Looking at the graphs shown, the answer is Option A.

Write an algebraic expression for each statement:

b. The tens digit of a number is b and the units digit is twice as big. What is the value of the number in terms of b if the digits are reversed?
I hope you can help me with these questions!!
For the given sentences, the algebraic expressions are:
a) N = 110*c - 300
b) N = 12*b
How to get the algebraic expressions?
For the first statement:
A 3-digit number, where the tens digit is c, can be written as:
N = 100*a + 10*c + b
Then the hundreds digit is a, and here we know that is 3 less than the tens digit, then:
a = c - 3
The ones digit is b, here we know that it is 0, then b = 0.
Replacing that in our number we get:
N = 100*(c - 3) + 10*c = 110*c - 300
N = 110*c - 300
That is the algebraic expression.
b) A two-digit number can be written as:
N = b*10 + a
Where b is the tens digit and a is the ones digit.
Here we know that the units digit is twice as bit as the tens digit, then:
a = 2b
Replacing that we get:
N = b*10 + a = b*10 + 2b = 12*b
N = 12*b
That is the algebraic expression.

A: A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left
B: A translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin
C: A 270-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left
D: A translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin
(Sorry if its hard to understand)
Answer: A
Step-by-step explanation:
Let's first review how turning about the origin changes a point's coordinates:
After rotating and translating some points, one can see the following pattern:
180° Rotation: (x,y) -> (-x,-y)90° Clockwise Rotation: (x,y) -> (y, -x)90° Counter-clockwise Rotation: (x,y) -> (-y, x)Translation a units to the left: (x, y) -> (x-a, y)Using these patterns will make it much easier to find the correct series of transformations than graphing each one.
A: A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left
Using the patterns found above, this set of transformations would make (x,y) move first to (-y, x), then (-y-1, x).
A(2,-2) -> A'(1,2)B(4,-2) -> B'(1,4)D(5,-3) -> D'(2,5)C(1,-3) -> C'(2,1)B: A translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin
This would make (x,y) move first to (x-1,y), then to (-y, x-1)
A(2,-2) -> A'(2, 1)B(4,-2) -> B'(2,3)D(5,-3) -> D'(3,4)C(1,-3) -> C'(3,0)C: A 270-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left
This would make (x,y) move first to (y, -x), then (y-1, -x)
A(2,-2) -> A'(-3, -2)B(4,-2) -> B'(-3,-4)D(5,-3) -> D'(-4, -5)C(1,-3) -> C'(-4, -1)D: A translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin
This would make (x,y) move first to (x-1,y), then (y, -x+1)
A(2,-2) -> A'(-2, -1)B(4,-2) -> B'(-2, -3)D(5,-3) -> D'(-3, -4)C(1,-3) -> C'(-3, 0)Therefore, the answer is A, as only it correctly matches to polygon A'B'D'C'.

The experimental probability is 5/14.
What is Experimental Probability?The term "probability" refers to an event's likelihood of happening. A probability has a value between 0 and 1, therefore if an occurrence is impossible, it has a probability of 0, and if it is certain, it has a probability of 1. Experimental probability is the probability that is established based on the outcomes of an experiment. The term "empirical probability" also applies to this. A probability that has been established by a series of tests is called an experimental probability. To ascertain their possibility, a random experiment is conducted and iterated over a number of times; each iteration is referred to as a trial. The goal of the experiment is to determine the likelihood that an event will occur or not.Since, 4 appeared five times over the total, The experimental probability is 5/14.

Answer:

Step-by-step explanation:
Range is the difference of the highest and lowest data.
Based on the given $20 is the highest and $5 is the lowest.
$20 - $5 = $15
Answer:
15
Step-by-step explanation:
you can think of this table as a data set--and you could even write it out
5, 5, 5, 10, ......... 20, 20 {I did not write it out in full of course}
so, when thinking about the range, we can think of it as a range of our data set.
We find the range of a data set by finding the difference between the highest and lowest values
So, we know that our highest data value (amount) is 20, and the lowest is 5:
20 - 5 = 15
meaning that there is a range of $15 in this data set of allowance amounts

What is the smallest possible length of the hypotenuse for a non-degenerate
right triangle with integer side lengths given that it has at least 1 leg of length
84.
The smallest possible length of the hypotenuse is 118
How to determine the hypotenuse?The given parameters are:
Triangle type: non-degenerate right triangleLegs: Length = 84 (at least 1)The non-degenerate implies that the right triangle has a positive area.
Since at least one length is 84, then both lengths can also be 84.
The hypotenuse is then calculated using the following Pythagoras theorem.
h^2 = 84^2 + 84^2
Evaluate the sum
h^2 = 14112
Take the square root of both sides
h = 118.8
Round down
h = 118
Hence, the smallest possible length of the hypotenuse is 118

Line segment pq is a directed line segment beginning at p(6,-5) and ending at q(-2,4). find point r on the line segment pr that partitions it into the segments pr and pq in the ratio 3:2.
Using proportions, the coordinates of point R are given as follows: R(1.2, 0.4).
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Segments pr and pq are partitioned in the ratio 3:2, hence:
[tex]PR = \frac{3}{5}PQ[/tex]
[tex]R - P = \frac{3}{5}(Q - P)[/tex]
The points are:
R(x,y).P(6,-5).Q(-2,4).For the x-coordinate, we have that:
[tex]R - P = \frac{3}{5}(Q - P)[/tex]
[tex]x - 6 = \frac{3}{5}(-2 - 6)[/tex]
x - 6 = -4.8
x = 1.2.
For the y-coordinate, we have that:
[tex]R - P = \frac{3}{5}(Q - P)[/tex]
[tex]y + 5 = \frac{3}{5}(4 + 5)[/tex]
y + 5 = 5.4.
y = 0.4.

The value of (-12) . 8 is -96 and the value of 14.(-5).(-11) is 770
How to solve the expressions?The question implies that we calculate the expressions in two different ways.
1) (-12).8
Way 1:
We have:
(-12).8
This means
(-12) . 8 = -12 * 8
Evaluate
(-12) . 8 = -96
Way 2
We have:
(-12).8
This means
(-12) . 8 = -12 * 8
Express 8 as 4 + 4
(-12) . 8 = -12 * (4 + 4)
Expand
(-12) . 8 = -12 * 4 -12 * 4
Evaluate the products
(-12) . 8 = -48 - 48
Evaluate the sum
(-12) . 8 = -96
Hence, the value of (-12) . 8 is -96
2) 14.(-5).(-11)
Way 1:
We have:
14.(-5).(-11)
This means
14.(-5).(-11) = 14 * -5 * -11
Evaluate
14.(-5).(-11) = 770
Way 2
We have:
14.(-5).(-11)
This means
14.(-5).(-11) = 14 * -5 * -11
Multiply -5 and -11
14.(-5).(-11) = 14 * 55
Multiply 14 and 55
14.(-5).(-11) = 770
Hence, the value of 14.(-5).(-11) is 770
