Answer:
Mutually exclusive
Step-by-step explanation:
Mutually exclusive events exist if only one of the events can occur on any one trial.
Events are considered to be mutually exclusive if only one of them can occur on any given trial.
So, option c. mutually exclusive is correct.
Define event.An event is a defined collection of outcomes of a random experiment in probability theory. Because the sample space is the collection of all possible outcomes to a random experiment, another definition of event is any subset of a sample space.
If two events cannot occur at the same moment, they are mutually exclusive or discontinuous.
Events are considered to be mutually exclusive if only one of them can occur on any given trial. So, option c. mutually exclusive is correct.

find the slope of
y=-x+7
Answer:
Slope = -1
Step-by-step explanation:
There is ways a 1 in front of an x if there is no other number
Evaluate - 2 + (-6) where a = 6.05 and b=3.611.
-a + (-b) where a = 6.05 and b = 3.611
Plug the variables in, then solve the equation
It should look like this:
- (6.05) + (-3.611) = -6.05 - 3.661 = - (6.05 + 3.661)
Add them together then make it negative.
Choose the system of equations which matches the following graph: (5 points)
Answer:
-5x + y = -7
2x + y = 0
Step-by-step explanation:
Equation of the line that slants upwards from left to your right:
The slope (m) = rise/run = (5/1) = 5
Using a point on the line, (2, 3) and the slope, substitute x = 2, y = 3, and m = 5 into y = mx + b to find the value of b.
Thus:
3 = 5(2) + b
3 = 10 + b
3 - 10 = b
-7 = b
Substitute m = 5 and b = -7 into y = mx + b
First equation of the system would be:
y = 5x - 7
Rewrite, you'd have:
-5x + y = -7
Equation of the line that slants downwards from left to your right:
Slope (m) = rise/run = -(2/1) = -2
y-intercept, b = 0 (the point where the line intercepts the y-axis)
Substitute m = -2 and b = 0 into y = mx + b.
y = -2x + 0
Rewrite, you'd have:
2x + y = 0
✔️The equations of the system are:
-5x + y = -7
2x + y = 0

PLS HELP! The number of tickets sold at the Amazing Art Museum on Saturday was 175% of the ticket sales on Friday. If 2,000 tickets were sold on Friday, how many tickets were sold on Saturday?
Which statements are correct? Check all that apply.
The answer will be less than 2,000 because 100 is less than 175.
The answer will be greater than 2,000 because 175 is greater than 100.
The answer will be equal to the sum of 2,000 and 175.
The answer will be equal to the product of 175 and 20.
The answer will be equal to the quotient of 2,000 and 175.

prove that:- (1-sinA)(1+sinA)÷(1+cosA)(1-cosA)=cot^2A
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 , then
sin²x = 1 - cos²x and cos²x = 1 - sin²x
Consider the left side
[tex]\frac{(1-sinA)(1 + sinA)}{(1+cosA)(1-cosA)}[/tex] ← expand numerator/denominator using FOIL
= [tex]\frac{1-sin^2A}{1-cos^2A}[/tex]
= [tex]\frac{1-(1-cos^2A)}{1-(1-sin^2A)}[/tex]
= [tex]\frac{1-1+cos^2A}{1-1+sin^2A}[/tex]
= [tex]\frac{cos^2A}{sin^2A}[/tex]
= cot²A = right side , thus proven
Solve the equation and check the solution.

Answer:
The temperature farthest from zero is 5
Step-by-step explanation:
the reason for this is because it doesn't matter whether that temperature is negative or positive because all the question is asking is...."how far from zero"....and would -4 be farther from zero....or would 5 be farther from zero. How I know this is absolute value is always positive. And absolute value of -4....is 4.....and absolute value of 5....is 5.
And 5 is 1 temperature more away from zero than -4.
Answer:
5 is the farthest from 0
-4 is the coldest temperature
5 is the warmest temperature
Step-by-step explanation:
The farthest from 0 could be negative or positive. It's just whichever one has the greatest absalute value (if you know that term, if not...), whichever one you would put up more fingers to count to.
In this case, according to the number line, the farthest from 0 into the nagatives is -4, but the farthest from 0 in the positives is 5. This means that 5 is the farthest from 5 because 5 takes 5 of your fingers to count to, whule -4 (yes, even though it's negative) takes just 4 fingers. This is a good way to visualize it until you can wrap your head around it!
The coldest is the lowest number. In this case, it's below zero. Below zero means negatives. In this case, -4 is the lowest number.
The warmest is the highest number. In this case, it's above zero. That means it's a positive number. 5 is the highest number here.

Point Q is the image of Q(4-6) under a translation by 1 unit to the right
Answer:
The image of Q(4,-6) under a translation by 1 unit to the right then the new coordinate point R( 5 , -6)
Step-by-step explanation:
Explanation:-
Given image Q( 4, -6)
Type of transformation change to co-ordinate point
a) Horizontal translation left
'C' units (x, y) ⇒ (x- c, y)
b) Horizontal translation right 'C' units (x, y)⇒( x +c ,y )
c) vertical translation up 'd' units (x, y)⇒( x ,y + d )
d) vertical translation down 'd' units (x, y)⇒( x ,y - d )
Now we will use Horizontal translation right 'C' units
image of Q(4-6) under a translation by 1 unit to the right
Q( 4 , -6) ⇒ The new image R( 4+1 ,-6)
The image of Q(4-6) under a translation by 1 unit to the right then the new coordinate point R( 5 , -6)

Answer:
12. The slope is 2
The y-intercept is 5
13. The slope is 1
The y-intercept is 5
14. The slope is 0.99
The y-intercept is 10
Step-by-step explanation:
12. If you use the rise over run method you go up by 2 and over 1. If you put rise over run you get 2/1 and that is equal to 2. So, slope is 2. The y-intercept is where x=0. If you look you can see that when x is 0, y is equal to 5. Therefore, the y-intercept is 5.
13. The slope is 1 because if you use the slope formula you can use two points like (1,6) and (2,7) in it to find that the slope is 1. You can also see that both the x and y variables go up by 1 each time, so the slope has to be 1. Once again the y-intercept is where x equals 0, even though it isn't shown on the graph we can infer it. At 0 days, the length of the kudzu would be 5 (because 5 is one step less than 6, remember the slope is 1).
14. The slope would have to be 0.99 because each consecutive download is 99 cents. There is a base membership fee of $10 so that has to be the y-intercept.

Vector you equals (-3,8), and vector v=(-14,6) match each vector operation with the magnitude of its resultant vector
drag the tiles to the boxes to form the correct pairs not all tiles will be used
Answer:
I hope this helps you
Step-by-step explanation:
The magnitude of given operations of vectors are found.
What are Vectors?Vectors are quantities which are having the independent properties of magnitude as well as direction.
Given that,
u = (-3, 8) and v = (-14, 6)
3u = (-9, 24) and 2v = (-28, 12)3u - 2v = (-9+28, 24-12) = (19, 12)
Magnitude of 3u - 2v = [tex]\sqrt{19^2+12^2}[/tex] = [tex]\sqrt{505}[/tex] units
2u = (-6, 16) and 3v = (-42, 18)2u - 3v = (36, -2)
Magnitude = [tex]\sqrt{36^2+(-2)^2}[/tex] = [tex]\sqrt{1300}[/tex] units
u = (-3, 8) and 4v = (-56, 24)u + 4v = (-59, 32)
Magnitude = [tex]\sqrt{(-59)^2+32^2}[/tex] = [tex]\sqrt{4505}[/tex] units
5u = (-15, 40) and v = (-14, 6)5u - v = (-1, 34)
Magnitude = [tex]\sqrt{1157}[/tex] units
7u = (-21, 56) and 2v = (-28, 12)7u - 2v = (7, 44)
Magnitude = [tex]\sqrt{1985}[/tex] units.
Hence the magnitude of vectors are found.

Answer:
Step-by-step explanation:
Total number of students who roller skated = 80
Number of students who roller skated with laser tag = 39
Number of students who roller skated with no laser tag = 80 - 39 = 41
Therefore, percentage of students who roller skated with no laser tag = [tex]\frac{41}{154}\times 100[/tex] = 27%
Since, number of students who played laser tag = 85
Percentage of students who played laser tag = [tex]\frac{85}{154}\times 100[/tex] = 55%
Total number of students who played no laser tag = 45% of 154 = 69
Number of students with no roller skates and no laser tag = 69 - 41 = 28
Percentage of students with no roller skates and no laser tag = [tex]\frac{28}{154}\times 100[/tex]
= 18%
Percentage of students who played with no rollers skates = (30 + 18)%
= 48%
Laser tag No laser tag Total
Roller skate 25% 27% 52%
No Roller skate 30% 18% 48%
