Answer:
You will need to count the amount of 0's and total them left to right = per question and total them top to bottom for answering a total
answering b total answering c total etc..
This creates line of 5 totals at the bottom of table and other totals per question = amount of questions x total.
The experimental probability is setting all 1/5 (1 answered question and multiplying it by the inverse of 4/5 non answered questions = 1/5 = 1/25
p) 1/5 x 1/5 = 1/25

5x-2y=11 and 3x+4y=4
Find the value of x and y in equation.
(1)×3 and (2)×5
15x-9y=33-(3)15x+20y=20-(4)Subtract both
[tex]\\ \sf\longmapsto -29y=13[/tex]
[tex]\\ \sf\longmapsto y=\dfrac{-13}{29}[/tex]
Put in eq(1)[tex]\\ \sf\longmapsto 5x+\dfrac{-117}{29}=11[/tex]
[tex]\\ \sf\longmapsto 5x=11+\dfrac{117}{29}=\dfrac{261+117}{29}=\dfrac{278}{29}[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{278}{145}[/tex]

What rotation centered about the origin maps (4, −7) to (7, 4) ?
90° counterclockwise
180° counterclockwise
270° counterclockwise
Answer:
A) 90° counterclockwiseStep-by-step explanation:
Preimage (4, - 7) and image (7, 4).
Rule applied:
(x, y) → (-y, x), this is a 90° counterclockwise rotationCorrect choice is A
Answer:
Option A
Step-by-step explanation:
90° counterclockwise rotation about origin rule is
(x,y)=(-y,x)So here
(4,-7)Rotate it
(-(-7),4)(7,4)Option A is correct

scale the numerator and the denominator down by a factor of 5 (just divide) to write a fraction equivalent to 30/70.
Answer:
6/14
Step-by-step explanation:
you need to just divide the denominator and numerator by 5. 30 / 5 is 6 and 70 / 5 is 14 so your answer is 6 / 14.
22. The function C= 75x + 2600 gives the cost, in dollars, for a small company to
manufacture x items. The function R = 225x-X gives the revenue, also in
dollars, for selling x items. How many items should the company produce so
that the cost and revenue are equal?
Given:
[tex]c=75x+2600\\[/tex]; where c is cost in dollars and x is items sold
[tex]r=225x-x^{2}[/tex]; where r is revenue in dollars and x is items sold
Equations:
[tex]x=\frac{-b\±\sqrt{b^2-4ac}}{2a}[/tex]
Answer:
For cost and revenue to be equal, the company should produce and sell 20 or 130 items.
[tex]x=20\\[/tex] or [tex]x=130[/tex]
Step-by-step explanation:
1. Set the equations equal to each other; [tex]75x+2600=225x-x^2[/tex]
2. Subtract [tex]225x-x^2[/tex] from each side; [tex]x^2-150x+2600=0\\[/tex]
3. Determine quadratic formula variables; [tex]a=1; b=-150; c=2600[/tex]
4. Substitute [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] into quadratic formula; [tex]x=\frac{-(150)\±\sqrt{(-150)^2-4*1*260}}{2*1}[/tex]
5. Solve quadratic formula; [tex]x_{1} = 130[/tex], [tex]x_{2}=20[/tex]

Given: m∠KER = m∠MEN
Prove: m∠1 = m∠3
Step-by-step explanation:
Statement Reason
m∠KER = m∠MEN Given
m∠KER = m∠1 + m∠2 Angle addition
m∠MEN = m∠2 + m∠3 Angle addition
m∠1 + m∠2 = m∠2 + m∠3 Substitution property of equality
m∠1 = m∠3 Subtraction property of equality

The function y=kx is given in the table. Find the coefficient k and fill in the table.
In the 1st table of values,
take x = 3 and y = 12
since,
y = kx
k = 12÷3
k = 4.
thus,
x = -2, y = -8
x = -1/3, y = -4/3
x = 0, y = 0
y = 16 , x = 3
y = 1/8, x = 1/32
All the best!

Answer:
the missing side of the triangle is 4, solving by the theorem of Pitagoras a^2 + b^2 = c^2
Using Pythagorean theorem
[tex]\\ \sf\longmapsto P^2=H^2-B^2[/tex]
[tex]\\ \sf\longmapsto P^2=8^2-(4√3)^2[/tex]
[tex]\\ \sf\longmapsto P^2=64-48[/tex]
[tex]\\ \sf\longmapsto P^2=16[/tex]
[tex]\\ \sf\longmapsto P=√16[/tex]

A lumberyard wanted to do a survey to see if its customers were interested in purchasing
rope along with lumber. Four different groups volunteered to do the study for them. Which
group should do the study so the bias is minimal?
Answer:
Choose a group to do the study that didn't have any volunteers that worked at the lumberyard, shopped at the lumberyard nor had any family members that shopped or worked there.
Step-by-step explanation:
Since you didn't specify any groups to chose from, I answered in the way that I thought there would be less bias.

.If the side of an equilateral triangle is 6cm, then the area of triangle is
Answer:
[tex]9\sqrt{3}[/tex] cm^2
Step-by-step explanation:
area of an equilateral triangle = [tex]\frac{s^{2} \sqrt{3} }{4}[/tex] (s = length of the side)
area = [tex]\frac{6^{2}\sqrt{3} }{4}[/tex]
area = [tex]\frac{36\sqrt{3} }{4}[/tex]
area = [tex]9\sqrt{3}[/tex] cm^2

For GJ in triangle GHJ, what is the corresponding segment in similar triangle HIJ?
IJ
How?
In triangle GHJ <H is right angle
So GJ is the hypotenuse.Now
in triangle HIJ
<H=90°IJ is the hypotenuse
So option A is correct
The corresponding segment for GJ in triangle GHJ in similar triangle HIJ is, 'JI'.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
⇒ Δ GHJ ≈ Δ HIJ
By the figure, we have;
In ΔGHJ, Side GJ is opposite side of the right angle.
And, In Δ JHI, Side JI is opposite side of the right angle.
Hence, The side JI in Δ JHI is corresponding segment in similar triangle GHJ.
