C. 2
D. 4
Answers
Answer:
The answer is A, 1/2.

The midpoint of AB is M ( 1 , − 3 ). If the coordinates of A A are ( − 6 , − 7 ),what are the coordinates of B?
Answers
Answer:
a= -4
b=1
Step-by-step explanation:
Midpoint=(1,-3)=(x,y)
A=(-6,-7)=(x1,y1)
Let ,the coordinates of B be 'a and b' .
So,
B=(a,b)=(x2,y2)
Using ,midpoint formula,
(x,y)=(x1+x2\2 , y1+y2 \2)
or, (1,-3)=(-6+a\2 , -7+b \2)
Now,
Taking the corresponding sides,
or, 1 =-6+a/2
or, 1*2=6+a
or, 2=6+a
or, 2-6=a
a=-4
Then,
-3= -7+b/2
or, -3*2= -7+b
or, -6 =-7+b
or, -6+7=b
b=1

Answer:
x=4 degrees
Step-by-step explanation:
its an equilateral triangle so all sides are equal, if one angle is 10x+20,then the rest are each 10x+20.This is a triangle and it adds up to 180 degrees. So in total, (10x+20)×3=30x+60.So you do this, 30x +60=180 degrees, you take the sixty to the other side and subtract it from 180 ,you'll get 120 degrees, then divide 120by 30x

In the diagram shown below, parallel lines m and n are crossed by transversals r and s. Which of the following is the sum of angles 1 and 2 pictured?
Answers
Answer:
3. 151°
Step-by-step explanation:
Since m and n are parallel, therefore:
m<1 + 75° = 180° (consecutive exterior angles are supplementary)
Subtract 75 from each side
m<1 = 180 - 75
m<1 = 105°
m<2 = 46° (corresponding angles are congruent)
Sum of <1 and <2 = 105° + 46° = 151°

Suppose that in an alternate universe, the gambler's fallacy is true: the more a gambler loses, the more likely she is to win the next game. To be precise, if the gambler loses a game, she will win the next game with probability 3/4. If the gambler wins the game, she will win the next game with probability 1/2.
Answers
Answer and explanation:
The gambler's fallacy is the fallacy of belief that if an event such as a loss occurs more frequently in the past, it is less likely to happen in the future. We assume here that this belief is true, therefore
If she loses, her probability of winning increases =3/4
If she wins, her probability to win is normal =1/2
Given that probability of winning is 1/2
Probability of losing is 1-1/2=1/2
Probability that she wins the tournament is probability that she wins the first two games and loses the last or wins the first game, loses the second and wins the last or loses the first game and wins the last two games or probability that she wins all three games
=1/2*1/2*1/2+1/2*1/2*3/4+1/2*3/4*1/2+1/2*1/2*1/2
=25/48
Probability of winning the tournament if she loses the first game
=1/2*3/4*1/2= 3/16

Are the lines y = –x – 4 and 5x -5y = 20 perpendicular? Explain.
Answers
Answer:
yes
Step-by-step explanation:
If 2 lines are perpendicular then the product of their slopes = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 4 ← is in slope- intercept form
with slope m = - 1
5x - 5y = 20 ( subtract 5x from both sides )
- 5y = - 5x + 20 ( divide all terms by - 5 )
y = x - 4 ← in slope- intercept form
with slope m = 1
Thus product of their slopes is - 1 × 1 = - 1
Therefore the lines are perpendicular
a student has answered 82% of the questions correctly in the examination. He made mistakes in 9 questions Calculate the toltal number of questions in the examination
Answers
Answer:
There is a total 50 questions.
Step-by-step explanation:
Let x = total questions in the exam
Since 82% of the test was scored correctly, that means 18% of the student's exam was scored incorrectly.
With this information we can write:
[tex]18\%x=9[/tex] (Given that the student made 9 mistakes)
[tex]x=9\div18\%[/tex] (divide 18% on both sides)
[tex]x=50[/tex]
∴ There was a total of 50 questions in the examination.
Read the information in the box below. Last year during the hurricane season, the amount of rain that fell on the Texas Gulf Coast in October was 14 inches, which was 312times more than the rainfall during September of the same year. How much rain fell during the month of September?
Answers
Answer: 4 inches
Step-by-step explanation:
From the question, we are informed that Last year during the hurricane season, the amount of rain that fell on the Texas Gulf Coast in October was 14 inches, which was 3 1/2times more than the rainfall during September of the same year.
The amount of rain that fell during the month of September can be calculated as:
= 14 inches ÷ 3 1/2
= 14 ÷ 7/2
= 14 × 2/7
= 28/7
= 4 inches
The rain that fell during the month of September was 4 inches.
