What's the equation of the line that's a perpendicular bisector of the segment connecting C (6, –12) and D (10, –8)? ANSWERS: A) y = –x – 2 B) y = x + 2 C) y = –1∕2x – 2 D) y = 2x – 6
Answer:
c
Step-by-step explanation:
The equation of the perpendicular bisector will be y = -x + 2. The correct option is A.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
The slope of the line is,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( -8 + 12 ) / ( 10 - 6 )
Slope = 4 / 4
Slope = 1
The slope of the perpendicular line will be inverse and opposite,
y = mx + c
y = -x + c
-8 = -10 + c
c = 2
The equation can be written as,
y = mx + c
y = -x + 2

Solve for x in the triangle. Round your answer to the nearest tenth.
Answer:
8.5
Step-by-step explanation:
For this we will use trigonometry.
First lable the diagram: 13 will be the hypotenuse (H), x will be the opposite(O). Therefore, we will use sin as it is SOH.
sin Θ = [tex]\frac{O}{H}[/tex]
sin 41 = [tex]\frac{x}{13}[/tex]
x = 13 sin 41
Type this into the calculator, then you will get 8.5287677377. Round this to the nearest tenth will be 8.5.
As the question does not give any units, there will be no need to write any units after the answer.

Eric throws a biased coin 10 times. He gets 3 tails. Sue throw the same coin 50 times. She gets 20 tails. Aadi is going to throw the coin once. 1. Which one of the following statements is, cotlrrect about the probability of Aadi getting Tails? A. Sue's estimate is best because she throws it 50 times. B. Sue's estimate is best because she gets more Tails. C. Sue's estimate is best because she throws it more times than Eric 2. Use Eric's and Sue's results to work out an estimate for the probability that Aadi will get Tails. Write out your fraction in the form a/b P. S WILL MARKS AS BRAINIEST AND THANK IF YOU ANSWER DECENTLY
Answer:
(1) Correct option (A).
(2) The probability that Aadi will get Tails is 0.40.
Step-by-step explanation:
The information provided is:
Eric throws a biased coin 10 times. He gets 3 tails.Sue throw the same coin 50 times. She gets 20 tails.The probability of tail in both cases is:
[tex]P(T|E)=\frac{3}{10}=0.30[/tex]
[tex]P(T|S)=\frac{20}{50}=0.40[/tex]
Here,
P (T|E) implies the probability of tail in case of Eric's experiment.
P (T|S) implies the probability of tail in case of Sue's experiment.
(1)
Now, it is given that Aadi is going to throw the coin once.
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
In this case we need to compute the probability of Aadi getting Tails in a single toss.
As Sue uses a larger number of trials in the experiment, i.e. n = 50 > 30 times, according to the Central limit theorem, Sue's estimate is best because she throws it .
Thus, the correct option is (A).
(2)
As explained in the first part that Sue's estimate is best for getting a tail, the probability that Aadi will get Tails when he tosses the coin once is:
[tex]P(\text{Aadi will get Tails})=P(T|A)[/tex]
[tex]=P(T|S)\\\\=0.40[/tex]
Thus, the probability that Aadi will get Tails is 0.40.
Answer:
The correct answer is C and 23/60
Step-by-step explanation:
Sue's estimate is best because she throws it more times than Eric.
This is because the more you throw a coin the more reliable the results will be compared to data from a coin that has been thrown less, therefore the answer is C.
For the second half you need to add the number of tails together to get you numerator and then add the amount of times the coin was thrown to get your denominator, (giving you 23/60)

During a fancy fair organized at school, the total amount of money collected was $54 000. The following table represents the amount of money collected from the different items:
Food and drinks: 27 000
Entertainment: 6000
Games: 12 000
Donations: 9000
What percentage of the money collected does each item represent?
Answer: Collected amount÷total amount x 100
Step-by-step explanation:
Food and drinks = [tex]\frac{27000}{54000}[/tex] x 100 = 50%
Entertainment = [tex]\frac{6000}{54000}[/tex] x 100 = 11% (11.1 - .1 recurring)
Games = [tex]\frac{12000}{54000}[/tex] x 100 = 22% (22.2- .2 recurring)
Donations = [tex]\frac{9000}{54000}[/tex] x 100 = 17% (16.6- .6 recurring)
Double checking - 50 + 11 + 22 + 17 = 100%
Hope this helps! :)
Answer:
Food & drinks = 50%
Entertainment = 11.1%
Games = 22.2%
Donations = 16.7%
Step-by-step explanation:
Basically, divide all of the amounts to $54000.

Name the set(s) of numbers to which –5 belongs.
whole numbers, integers, rational numbers
whole numbers, natural numbers, integers
integers, rational numbers
rational numbers
Answer:
integers, rational numbers
Explanation:
Integers are any whole number (positive or negative). -5 is a whole number, not a fraction or decimal.
Rational numbers can be written in the fraction form a/b where a and b are both integers and b does not equal 0. -5 can be written as -5/1.
There are two sets of real numbers that include the number -5. which represents integers and rational numbers.
What is a rational number?A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.
It can be a/b of two integers, a numerator a, and a non-zero denominator b.
What are Integers?Integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer. Fractional numbers are not included in integers. Integers are represented by the symbol Z.
The result is rational because -5, can be expressed as a ratio of two integers that can be -5/1 of two integers, a numerator 5, and denominator 1 ( which is a non-zero).
There are two sets of real numbers that include the number -5.
It represents Integers and rational numbers.
Hence, the correct answer would be Option (C).

Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 13 and h = 4 , thus
A = [tex]\frac{1}{2}[/tex] × 13 × 4 = [tex]\frac{1}{2}[/tex] × 52 = 26 units² → A
Answer:
A, 26
Step-by-step explanation:
Since the area of a triangle is one half base times height, and we have our height as 4, and our base as 13, we get 1/2 * 13 * 4, which is equal to 13 times 2, which is 26. Thus, our answer is A, 26.

largest angles of ALMN?
The smallest angle of the triangle is
The largest angle of the triangle is
Answer:
Smallest angle - ∠M
Largest angle - ∠N
Step-by-step explanation:
In a triangle opposite side of a largest angle is largest and opposite side of a the smallest angle is smallest.
In the given triangle LMN,
Side lengths of the triangle have been given as,
LM = 27 in.
MN = 25 in.
LN = 24 in.
Relationship in these sides will be,
LM > MN > LN
Therefore, relationship in their opposite sides will be,
∠N > ∠L > ∠M
The smallest angle of the triangle is angle M.
And the largest angle of the triangle is angle N.
