EXPLANATION
The number of sophmores is 2+25+3 = 30.
Of these sophmores, 2 drive to school.
So the probability that a student drives to school, given that they are a sophmore, is 2/30, or approximately 0.07.

what is equivalent to 6.253x10-2
rational number between -1 and 1
Answer:
[tex]\dfrac{-1}{2}[/tex]
Step-by-step explanation:
We need to find ration numbers between -1 and 1.
Multiplying and dividing both -1 and 1 by 2.
[tex]\dfrac{-1\times 2}{2}=\dfrac{-2}{2}[/tex]
and [tex]\dfrac{1\times 2}{2}=\dfrac{2}{2}[/tex]
Now, the rational number between -2/2 and 2/2 is [tex]\dfrac{-1}{2}[/tex].

Answer:
An = 6 + (n-1)5
A25 = 120
Step-by-step explanation:
Given sequence;
6 , 11 , 16 , 21 , 26 , .......
Find:
25th term
Computation:
First term of AP (a) = 6
Common difference (d) = a2 - a1
Common difference (d) = 11 - 6
Common difference (d) = 5
An = a + (n-1)d
So,
An = 6 + (n-1)5
So,
If n = 25
A25 = 6 + (25 - 1)5
A25 = 6 + (24)5
A25 = 6 + 120
A25 = 120

Professor M presented the pair of equations shown below:
y = 6x − 10
y = 2x − 2
Part A: Explain to Professor M how you will solve the pair of equations by using either substitution or elimination. Show all the steps you use and write the solution in (x, y) form.
Part B: If she asked you to graph the two equations, at what point will the lines representing the two equations intersect? Explain how you know this.
Answer:
A) The solution is x = 2 and y = 2
B) The graphs would intersect at the point (2, 2).
Step-by-step explanation:
A)
We start with the system of equations:
y = 6*x - 10
y = 2*x - 2
To solve this, the first step is to isolate one of the variables in one of the equations.
Here we can see that the variable "y" is already isolated in both equations, so we can skip that step.
Now we can "replace" the "y" in one of the equations for the correspondent expression in the other.
we can write:
(6*x - 10) = y
and for the second equation, we know that y = 2*x - 2
So replacing that, we get:
6*x - 10 = 2*x - 2
Now we can solve this for x.
6*x - 2*x = - 2 + 10
4*x = 8
x = 8/4 = 2
Now to find the value of y, we can just input this value of x in any one of the two equations:
y = 6*2 - 10 = 12 - 10 = 2
y = 2*2 - 2 = 4 - 2 = 2
So the solution of the system is:
x = 2, y = 2
B) Because the solution of the system is the ordered pair (2, 2), this means that the ordered pair belongs to the graph of both lines, then we can conclude that these lines will intersect at that point (the one that is common to both lines). Actually, when we have a system of equations, graphing both equations and finding the points where the graphs intersect is one method to estimate the solution of the system.

A circle has a circumference of
3.14
3.143, point, 14 units.
What is the diameter of the circle?
Answer:
The diameter is 1 unit.
Step-by-step explanation:
The formula for circumference of a circle of diameter d is C = (3.14)d, where 3.14 is a close approximation of π (pi).
Here the circumference is given and is 3.14 units. Because C = 3.14d,
the diameter of this circle is 3.14/3.14, or simply 1 (unit).

find the equation of the parabola with its focus at (5,0) and it’s directrix y=2
Answer:
Option A
Step-by-step explanation:
From the question given in the picture attached,
Directrix of the parabola → y = 2
Focus of the parabola → (-5, 0)
Since, focus is below the directrix, parabola will open open downwards.
Equation of the parabola will be in the form of,
y - k = -4p(x - h)²
Here, (h, k) is the vertex of the parabola
p = Distance between vertex and focus or distance between vertex and directrix
Since, distance between vertex and focus = Distance between vertex and directrix
Therefore, vertex of the parabola → (-5, 1)
Now distance (p) between vertex (-5, 0) and focus (-5, 1) = 1 unit
By substituting these values in the equation,
y - 1 = -4(1)[x - (-5)]²
y - 1 = -4(x + 5)²
y = -4(x + 5)² + 1
Option A will be the answer.
Given circle Q with a measure of SR= 120° and a radius of 9 feet, as shown below.
Determine the arc length of SR. Use mathematics to explain how you determined your answer
Has photo ❤️
Answer:
18.84feet
Step-by-step explanation:
Length of an arc = rtheta
radius r = 9feet
theta = SR= 120°
Convert theta to radians
theta = 120π/180
theta= 2π/3
Length of the arc = 9 * 2π/3
L = 18π/3
L = 6π
L = 6(3.14)
L = 18.84feet
Hence the length of the arc is 18.84feet

a ladder reaches the top of a 20 foot building. the ladder is 4.5 feet away from the building. how long is the ladder?
a 24.5 feet
b 19.5 feet
c 20.5 feet
d 3.5 feet
Answer:
C
Step-by-step explanation:
do that with pithagoras:
20² + 4,5² = x²
400 + 20,25 = x²
420,25 = x²
x = [tex]\sqrt{420,25}[/tex]
x ~ 20,5
Letter C: 20,5 feet
The required length of the ladder is given as 20.5 feet. Option C is correct.
What are Pythagorean triplets?In a right-angled triangle, its side, such as the hypotenuse, is perpendicular, and the base is Pythagorean triplets.
Here,
The height of the building is 20 feet,
base length from the bottom of the building to the bottom of the ladder is 4.5 feet,
Let the hypotenuse length of the ladder be x,
Applying the Pythagoras theorem,
x² = 4.5² + 20²
x = √[420.25]
x = 20.5 feet
Thus, the required length of the ladder is given as 20.5 feet. Option C is correct.

While this may look like it's a lot to keep track of, its not too bad. We have 7 copies of (-8) in total. The 7 copies due to the exponent of 7. Nice work on getting the correct answer for the second part.
-----------
A further detailed breakdown:
(-8)^3 is the same as (-8)(-8)(-8) so we have three copies here
(-8)^4 is the same as (-8)(-8)(-8)(-8) and we have four copies
Overall, we have 3+4 = 7 copies total.

Factoriz 5wp+15wp+20wr
Answer:
20w(p + r)
Step-by-step explanation:
It's readily evident that 5w is common to all three terms. Factoring out 5w, we get:
5w(p + 3p + 4r), or
5w(4p + 4r), or
20w(p + r)
Answer:
20w(p + r)
Step-by-step explanation:
We can factorize it in the following way...
5wp + 15wp + 20wr = 20wp + 20wr = 20w(p + r)
Graph the equation y = x2 + 8x + 12 on the accompanying set of axes. You must
plot 5 points including the roots and the vertex. Using the graph, determine the
vertex of the parabola.
Answer:
Step-by-step explanation:
Roots: set y = x^2 + 8x + 12 = 0 and solve for x: x + 6 = 0, so x = -6 is one root. The other is x = -2. The corresponding points are (-6, 0) and (-2, 0).
y-intercept: Let x = 0. Then y = 12. The y-intercept is (0, 12).
Axis of symmetry: x = -b / (2a) => x = -8/(2*1) = -4: x = -4
Vertex y-value: evaluate y at x = - 4: (-4)^2 + 8(-4) + 12 = -4: (-4, -4)
Arbitrarily chosen x value: x = 1 => 1^2 + 8(1) + 12 = 21: (1, 21)
The five points are: (-6, 0) and (-2, 0), (0, 12), (-4, -4), (1, 21). The vertex is (-4, -4). The parabolic graph opens UP.
The vertex of the parabolic equation y = x² + 8x + 12 will be at (-4, -4).
What is the equation of the parabola?Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The equation is given below.
y = x² + 8x + 12
Conver the equation into a vertex form. Then we have
y = x² + 8x + 12
y = x² + 8x + 16 - 16 + 12
y = (x + 4)² - 4
The vertex of the parabolic equation y = x² + 8x + 12 will be at (-4, -4).
The graph is given below.
