Answer:
If you have 10 phones, this is the 100%
then:
10 = 100%
Now we know that only 3 of them work correctly, then the percentage of pones that works correctly can be related to:
3 = X%
To find the value of X%, we can take the quotient of the equations:
3 = X%
and
10 = 100%
We ge:
(3/10) = (X%/100%)
We solve this for X and we get:
(3/10)*100% = X% = 30%
As we already know.
Now let's see how this percentage changes if we add more phones that do not work correctly.
Now we add another phone that does not work, so we have a total of 11 phones and 3 of them work.
then:
3 = X%
11 = 100%
The quotient is:
(3/11) = (X%/100%)
(3/11)*100% = X% = 27.3%
If we add another phone, now we have 12 phones and only 3 of them works, then 12 is the 100%, and we have the equations:
3 = X%
12 = 100%
Then we get:
(3/12) = X%/100&
(3/12)*100% = X% = 25%

See belowStep-by-step explanation:
Given the data set of 15 where:
Mean = 7Median = 6Mode = 5The minimum is 1 and the maximum is 10As per given we conclude
The set will have 7 numbers before 6 and 7 numbers afterSum of 15 numbers is 15*7 = 105The most used number is 5a) Possible set is:
1, 5, 5, 5, 5, 5, 5, 6, 9, 9, 10, 10, 10, 10, 10b) Add number 20, the set will be:
1, 5, 5, 5, 5, 5, 5, 6, 9, 9, 10, 10, 10, 10, 10, 20The mean is different as we have now more numbers with different sum:
(105 + 20)/(15 + 1) = 125/16 = 7.8125The median is different now and moves to the right as 20 added to the far right:
(6 + 9)/2 = 7.5The mode stays same as still most used number is 5:
5There are 4 ropes. Each rope is 3 \large \frac{1}{4} feet long. Select the 3 expressions that would give the total length of the ropes. a \large 3\frac{1}{4}+3\frac{1}{4}+3\frac{1}{4}+3\frac{1}{4} b 4 x \large \frac{12}{4} c 4 x \large \frac{13}{4} d \large \frac{12}{4}+\frac{12}{4}+\frac{12}{4}+\frac{12}{4} e \large \frac{13}{4}+\frac{13}{4}+\frac{13}{4}+\frac{13}{4}
Answer:
The correct answers are;
4 * 3 1/4
3 1/4 + 3 1/4 + 3 1/4 + 3 1/4
13/4 + 13/4 + 13/4 + 13/4
Step-by-step explanation:
Given 4 ropes each 3 1/4 feet long
1 rope = 3 1/4 feet long
4 ropes = x
cross multiply
1 * x = 4 * 3 1/4
x = 4 * 3 1/4
Since 3 1/4 is in 4 places, the total length can also be expressed as;
3 1/4 + 3 1/4 + 3 1/4 + 3 1/4
We can also rewrite as an improper fraction
Since 3 1/4 = 13/4
Total length = 13/4 + 13/4 + 13/4 + 13/4

Write in equation in slope form of the line shown
Answer:
y=2x-5
Step-by-step explanation:
Slope intercept form is y=mx+b, with m being the slope and b being the y-intercept.
Slope is found through (y2-y1)/(x2-x1) and when the values are plugged in you get (-3-1)/(1-3) which equals -4/-2 or 2.
y=2x+b
Since b is the y-intercept, you plug in the value of the point where the line crosses over the y axis. In this case, that value is -5, so you get y=2x-5.

BC reflects about a line such that Nis the reflection of Band O is the reflection of C. Point Nis shown on the coordinate plane, but point ois
not
The coordinates of point Oare (
Pacot
Not
Answer:
From my research, the coordinate points can be found on image below. Since N is the reflection of B and O is the reflection of C, if we were to draw a line to the right of N and a vertical line below C, the point of intersection of these two lines should give us the location of point O. Doing just that, point O is found at (5,5).
Step-by-step explanation:
Hope I helped You :) have a good day.
The coordinates of point O of the given Reflection is; 5, 5
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Since, The coordinates point is missing and so I have attached it.
Now, from the question, we are told that N is the reflection of B and O is the reflection of C.
Thus, from the attached image, drawing a line to the right of N and a vertical line below C, the point of intersection of these two lines would give us the location of point O.
Hence, Drawing a line to the right of N and a vertical line below C, the point of intersection of these two lines which is point O has coordinates at (5,5).

The edge of a cube is 4 inches.
The area of a cross section perpendicular to one face is
square inches, and its perimeter is
inches
Answer:
Sketch of a cube with side = 4 in as shown.
The shaded area is perpendicular to the right and left vertical faces of the cube, so the cross section is a square with each side equal to 4 in.
The area of the cross section is
4*4 = 16 in²
The perimeter of the cross section is
4+4+4+4 = 16 in.

work below
Note: Used Elimination Method
Multiply the first equation by -2,and multiply the second equation by 1.
−2(−2x+y=3)
1(3x+2y=−15)
Becomes:
4x−2y=−6
3x+2y=−15
Add these equations to eliminate y:
7x=−21
Then we solve 7x = −21 for x:
7x = −21
7 7
(we Divide both sides by 7)
x=−3
Now that we've found x let's put it back in to solve for y.
Put down an original equation:
−2x+y=3
Substitute−3 for x in−2x+y=3:
(−2)(−3)+y=3
y+6=3(Simplify both sides of the equation)
y+6+−6=3+−6(Add -6 to both sides)
y= −3
Solution
(-3, -3)
