5 is the correct scale factor
This is because there are 5 little segments that go from C to the larger point in the top right corner. We need 5 pieces of segment CB to get segment CB' where B' is that top right corner point.
Put another way: If the distance from C to B is 1 unit, then the distance from C to B' is 5 units. This shows the distance has multiplied by 5, and that's the scale factor.
Is 3 + (-4) the same as -4 + 3? Explain
Answer:
Yes, 3 + (-4) is the same as -4 + 3.
Step-by-step explanation:
When doing addition problems such as this, the order of the numbers does not matter, even when negative numbers are included.
For example, 1 + 2 or 2 + 1 would equal 3.
3 + (-4) = -1
-4 + 3 = -1

B•y-2=-3/4(x-6)
C•y-6=4/5(x-3)

to deliver newspapers to his 40 customers. How
long will it take Bill to complete his route if he
adds 20 more customers in his neighborhood?
Answer:
75 min or 1 hour 15 min
Step-by-step explanation:
20 is 50% of 40 so add 50% of 50 min to the total. Half of 50 is 25 so you add 25 min
Answer:
if bill takes
40 customers =50 minutes
20 customers= 50÷2 =25 minutes

A coin is tossed and a die is rolled. What is the probability that the coin lands heads up and the number rolled is a 6 ?
The probability that the coin lands heads up and the number rolled is a 6 is 1/12.
Given that a die is rolled and a coin is tossed.
We have to find the probability that the coin lands heads up and the number rolled is a 6.
Probability of getting heads in tossing a coin = 1/2
Probability of getting 6 in rolling a die = 1/6
The event of tossing a coin and rolling die are independent.
Hence,
Probability that the coin lands heads up and the number rolled is a 6 =
Probability of getting heads in tossing a coin * Probability of getting 6 in rolling a die = (1/2)*(1/6) = 1/12.

Points A and B have coordinates A(-4,2) and B(3,-6). Find the coordinates of point P, the weighted average of points A and B, in which point A has a weight of 4 and point B has a weight of 3.
A (-7/2, -5)
B (-1,-10/7)
C (-1/2, -2)
D (0,-20/7
The coordinates of the point P is P(x, y) = (- 1, - 10 / 7). (Correct choice: B)
How to determine the coordinates of a resulting point by weighted averages approach
In this problem we find the coordinates of two points on Cartesian plane, of which we must determine the location of a third point by using a formula based on a weight average-like formula:
P(x, y) = (4 / 7) · A(x, y) + (3 / 7) · B(x, y)
P(x, y) = (4 / 7) · (- 4, 2) + (3 / 7) · (3, - 6)
P(x, y) = (- 16 / 7, 8 / 7) + (9 / 7, - 18 / 7)
P(x, y) = (- 7 / 7, - 10 / 7)
P(x, y) = (- 1, - 10 / 7)
The coordinates of the point P is P(x, y) = (- 1, - 10 / 7).

The hobbits Frodo, Sam, Pippin and Merry have breakfast at different times. Each one takes a quarter of the porridge in the pan, thinking that the other three have not yet eaten. What fraction of the porridge is left after all four hobbits had their breakfast?
Step-by-step explanation:
Let us start with Frodo's breakfast. He starts eating a quarter of the porridge. Let us say the porridge is 100 spoons, to make dividing easier. After Frodo we have [tex]\frac{3}{4}[/tex] left of the original bowl; we are left with 75 spoons.
100 - [tex]\frac{1}{4}[/tex] = 100 - 25 = 75
Next, comes Sam's breakfast. He eats 75 - [tex]\frac{1}{4}[/tex] = 75 - 18.75 = 56.25 spoons left.
Next, we have Pippin's breakfast. He eats 56.25 - [tex]\frac{1}{4}[/tex] = 42.1875 spoons.
Lastly, we have Merry's breakfast. He eats 42.1875 - [tex]\frac{1}{4}[/tex] = 31.640625 spoons.
Now, we know we have 31.640625 spoons left. However, we need to know what fraction this is out of the original porridge bowl. So, we do:
31.640625 * 100 = 3164.0625 * 1 = 3164.0625
3164.0625% of the bowl remaining!
What a yummy breakfast!
It's vote counting day for an election held in a country. The 3 TV stations updated the public about the number of votes cast starting at 7:00 in the morning. TV station A announces the vote counts every 2 hours, TV station B announces it every 3 hours, and TV station C announces it every 4 hours. At what time will the three TV stations announce the vote counts at the same time?
The 3 tv stations will announce the news again after 12 hours at 7 in the evening which is calculated by taking the LCM of the 3 intervals.
LCM or lowest common multiple of 2 or more numbers is defined as the minimum number which is lowest multiple of of the 2 or more numbers which is equal.
In mathematics and number theory. Since the result of dividing an integer by zero is not defined this definition only applies if both x and y are not equal to zero. However, given that 0 is the only common multiple of x and 0, some authors define LCM(x,0) as 0 for all x.
The intervals in which channels announce the news are 2 hours, 3 hours and 4 hours.
So we have to find the LCM of the numbers.
LCM(2,3,4)=12 as 12 is the smallest integer which is divided by all the other 3 numbers.
So the news channels will announce the news after 12 hours.
Since they announced at 7 in the morning so they would all announce the news again at 7 in the evening.

And with alpha and degrees of freedom χ²= 28.412
Chi - Square Distribution:
The chi square distribution is the continuous distribution, where the degree of freedom is the sample size minus 1, and it is the parameter of the chi-square probability distribution.
Given,
Here we need to find the value of x² values that separate the middle 80 % from the rest of the distribution for 20 degrees of freedom.
Based on the given details,
Degrees of freedom = 20
Middle separate value = 80%
Which is equal to 0.8 in decimal point.
The significance level
=> ∝ = 1 - 0.8
=> ∝ = 0.2
But we need the area of the middle so we divide this significance level with 2
so that we get exactly the middle area .
Dividing
=> 0.2/2= 0.1
So we will have two values for chi square
One with
=> 0.8 + 0.1 = 0.9 alpha
and
one with
=> 0.1 alpha .
This is because the chi square is right tailed.
Now based on the chi square distribution table,

The lengths 12, 16, 10, 5, and 2 of the sides, AP, DQ, CS, PQ, and QR respectively, using the triangle proportionality theorem, gives the area of trapezoid BRSC as 40 square units.
What is the triangle proportionality theorem?The triangle proportionality theorem states that a line parallel to a side of a triangle and also intersects the other two sides, it divides the two sides proportionally.
Based on the theorem, where the other two sides are perpendicular, the parallel side divides the two sides equally.
The given parameters are;
The figure represented by ABCD = A parallelogram
The lengths of the sides of the figure are;
AP = 12
DQ = 16
CS = 10
PQ = 5
QR = 2
Required: The area of figure BRSC
Solution;
Given that ABCD is a parallelogram, we have;
AD = BC (definition of a parallelogram)
Using the triangle proportionality theorem, we have;
PQ = RS = 5 (segments bounded by equidistant parallel lines)
DQ - CS = AP - BR = 16 - 10 = 6 (Parallel vertical lines intersected by parallel lines at different heights)
AP - BR = 6
BR = 12 - 6 = 6
The area, A, of trapezoid BRSC is therefore;
A = RS × (BR + CS)/2
Which gives;
A = 5 × (6 + 10)/2 = 40

What exactly is a pie chart?A pie is a kind of chart that displays data in the form of a circular graph.
We understand that the total value of the pie is always 100%. It is also understood that a circle does have a circumference of 360°. As an outcome, the total of all data points equals 360°. There appear to be mainly two pie chart formulas based on these:
To determine a percentage of a data set, we use the following format: 100 (Frequency ÷ Total Frequency) × 100To convert the information to degrees, we use the given equations: (Informed Data ÷ Total value of Data) × 360°When a circle is completely rotated, it forms a 360-degree angle in the center.
At the center of the circle, a complete rotation yields 360 degrees.
The total percentage of all colors is 100%.
Divide a value of green by 3.6 since 360 degrees / 100% = 3.6.
The total percentage of green displayed by the spinner's pointer is 80%.
P (probability of the cursor landing on green) = 80/3.6
