what is the difference between bisectors and perpendicular bisectors?
Final answer:
A bisector cuts a line segment or angle into two equal parts, while a perpendicular bisector not only does that but also intersects the line segment at a right angle.
Explanation:
In mathematics, a bisector is a line segment or line that divides an angle or segment into two equal parts. It cuts the angle or segment into two congruent angles or segments. For example, if you have a line segment AB and its bisector is a line segment CD, then CD divides AB into two congruent segments AC and CB.
A perpendicular bisector is a type of bisector that not only divides a line segment into two equal parts, but it also intersects the line segment at a right angle (90 degrees). So, in addition to being equidistant from the two endpoints of the line segment, the perpendicular bisector is perpendicular to the line segment as well.

How do you rewrite 0.912912 using bar notation
The number 0.912912 can be written in bar notation as 0.912, with a bar over 912 to indicate the repeating decimals. This method is commonly used in mathematics to represent repeating decimals.
Explanation:To rewrite the number 0.912912 using bar notation, consider the part of the decimal that repeats. In this case, the repeating section is 912. Therefore, the number can be written as 0.912 where the 912 has a bar over it to represent the fact that it repeats. Bar notation is a way in mathematics to represent repeating decimals. The bar, or vinculum, shows which numbers repeat in the decimal. For this number, 0.912 with a bar over 912 is the way it would be written in bar notation.

The sales tax rates from 4 different countries are shown in the table. Convert each sales tax rate to a decimal. Then sort the countries from least to greatest tax rates.
Hamilton: 9/160
Oakland: 5.75%
Green: 5 7/8%
Campbell: 11/200
Converting Sales Tax Rates and Sorting by Rate
Convert Fractions to Decimals:
Hamilton: 9/160 = 0.05625
Oakland: 5.75% = 5.75 / 100 = 0.0575
Green: 5 7/8% = 47/8 / 100 = 0.05859375
Campbell: 11/200 = 0.055

Maryann is testing the effectiveness of a new acne medication. There are 100 people with acne in the study. Fifty-five patients received the acne medication, and 45 other patients did not receive treatment. Thirty of the patients who received the medication reported clearer skin at the end of the study. Twenty-two of the patients who did not receive medication reported clearer skin at the end of the study. What is the probability that a patient chosen at random from this study took the medication, given that they reported clearer skin?
Answer: 58 %
Step-by-step explanation:
Let M represents the event of taking medicine, M' represents the event of not taking medicine and C represents the event of clearing skin,
Thus, according to the question,
n(M) = 55,
n(M') = 45,
n(M∩C) = 30,
n(M'∩C)= 22,
⇒ n(C) = n(M∩C) + n(M'∩C) = 30 + 22 = 52
Let S shows the total number of people,
⇒ n(S) = 100
Hence, the probability of cleared skin,
[tex]P(C)=\frac{n(C)}{n(S)}=\frac{52}{100}=0.52[/tex]
And, the probability of cleared skin of that people who took the medicines,
[tex]P(M\cap C)=\frac{n(M\cap C)}{n(S)}=\frac{30}{100}=0.3[/tex]
Thus, the probability that a patient chosen at random from this study took the medication, given that they reported clearer skin,
[tex]P(\frac{M}{C})=\frac{P(M\cap C)}{n(C)}=\frac{0.3}{0.52}=0.57692307692\approx 0.58 = 58\%[/tex]
Answer: 0.58
Step-by-step explanation:
Let A = Event that the patients received the acne medication.
B = Event that the patients did not receive the acne medication.
C = Patient reported reported clearer skin.
Now,
[tex]P(A)=\dfrac{55}{100}=0.55\ \ ,P(B)=\dfrac{45}{100}=0.45[/tex]
[tex]P(C|A)=\dfrac{30}{55}\ \ , P(C|B)=\dfrac{22}{45}[/tex]
Using Bayes theorem, The probability that a patient chosen at random from this study took the medication, given that they reported clearer skin:
[tex]P(A|C)=\dfrac{P(A)\cdot P(C|A)}{P(A)\cdot P(C|A)+P(B)\cdot P(C|B)}\\\\=\dfrac{0.55\cdot\dfrac{30}{55}}{0.55\cdot\dfrac{30}{55}+0.45\cdot\dfrac{22}{45}}=0.576923076923\approx0.58[/tex]
Hence, the required probability : 0.58

What is the midpoint of AB if A = (−2, 2) and B = (3, −1)? Enter your answer in the boxes below.
Answer:
[tex](\frac{1}{2}, \frac{1}{2})[/tex]
Step-by-step explanation:
Since, the coordinates of the midpoint of a line segment having the endpoints [tex](x_1,y_1)[/tex] and [tex](x_2, y_2)[/tex] are,
[tex](\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]
Here,
[tex]x_1=-2, y_1=2, x_2 = 3, y_2=-1[/tex]
Hence, the coordinates of the midpoint of segment AB are,
[tex](\frac{-2+3}{2},\frac{2-1}{2})[/tex]
[tex](\frac{1}{2}, \frac{1}{2})[/tex]
How do you turn -13 into an improper fraction
60 + 84
the sum of the numbers as a product of their GCF is?
Final answer:
The sum of 60 and 84 expressed as a product of their Greatest Common Factor is 144. You determine this by first finding the GCF, which is 12, and then adding the other factors (5 and 7) together and multiplying by the GCF.
Explanation:
To find the sum of the numbers 60 and 84 as a product of their Greatest Common Factor (GCF), you first need to calculate the GCF of the two numbers. The GCF of 60 and 84 is 12. You can divide each number by 12 to find the other factors, which are 5 for 60 and 7 for 84. Therefore, the sum of the numbers can be expressed as the product of their GCF and the sum of these other factors:
60 + 84 = (12 × 5) + (12 × 7)
GCF × (sum of other factors) = 12 × (5 + 7)
Now you can add the other factors:
5 + 7 = 12
Then multiply by the GCF:
12 × 12 = 144
So, the sum of the numbers expressed as a product of their GCF is 144.

200 +6m = 500-6m
add 6m to each side
200+12m = 500
subtract 200 from each side
12m = 300
divide both sides by 12
m = 300/12 = 25

check:
200+ 25*6 = 200 +150 = 350

The greatest common factor of a number n and 6 is 3. What are all of he possible whole-number values for n?
Answer: Odd multiple of 3.
[tex]3,\ 9,\ 15,\ 21, \ 27, \ 33, \ 39,\ 45,...........[/tex]
Step-by-step explanation:
Given : The greatest common factor of a number n and 6 is 3.
Then, it is clear that n should be a multiple of 3.
Prime factorization of 6 :
[tex]6=2\times3[/tex]
So for n a even number then the greatest common factor will be 6.
Thus , the possible choice for n is a odd multiple of 3.
Hence, the possible whole-number values for n are :
[tex]3,\ 9,\ 15,\ 21, \ 27, \ 33, \ 39,\ 45,...........[/tex]

Solution: The correct option is second option, i.e., [tex]y=(x+4)^2-1[/tex].
Explanation:
The standard form of the parabola along the y-axis with vertex (h,k) is [tex]y=a(x-h)^2+k[/tex].
Since the turning point is given as [tex](-4,-1)[/tex].
Put these values in the standard form of the parabola.
[tex]y=a(x+(-4))^2+(-1)[/tex]
[tex]y=a(x+4)^2-1[/tex] .....(1)
The parabola passes through the points (-5,0), (-3,0) and (0,15). It means each point will satisfy the above condition.
Put x = 0 and y = 15 in the equation (1).
[tex]15=a(0+4)^2-1\\16=4^2a\\16=16a\\a=1[/tex]
Put a = 1 in equation (1).
[tex]y=1(x+4)^2-1[/tex]
Therefore, the The correct option is second option, i.e., [tex]y=(x+4)^2-1[/tex].
