Select the correct answer.
Hillary and her friends are trying to decide whether to go bowling or to a movie. Which method could they use to fairly decide which activity they
will do?
A.Flip a coin twice. If the coin lands on heads both times, they will go bowling. If it doesn't, they will go to a movie.
B.Flip a coin twice. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a
movie.
C.Flip a coin three times. If the coin lands on tails all three times, they will go to a movie. If it doesn't, they will go bowling.
D.Flip a coin three times. If the coin lands on heads twice and tails once, they will go to a movie. If it doesn't, they will go bowling.
Answer:
D.
Step-by-step explanation:
I would have to say D is the best answer since then it's truly based on luck and it's almost as if it's being flipped once
Hillary and her friends could flip a coin twice to fairly decide which activity they will do. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a movie.
What is probability?Probability is the ratio that shows the likelihood of an event occurring out of all the other possible events.
Hillary and her friends need to use a fair method to determine which activity to do. For this, the probability should be 1/2. We should observe the given options and find which is the fairer method.
In the case of option A, the probability of that event occurring is 1/4.In the case of option B, the probability of that event occurring is 1/2.In the case of option C, the probability of that event occurring is 1/8.In the case of option D, the probability of that event occurring is 3/8. We can see that Option B is the only event having a probability of 1/2.Therefore, Hillary and her friends could flip a coin twice to fairly decide which activity they will do. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a movie. The correct answer is Option B.

Write each absolute value in a box to show the order from least to greatest.
|11| |–8| |–2| |5| |–12|
Answer:
|–2| |5| |–8| |11| |–12|
Answer:
|-2|,|5|,|-8|,|11|,|-12|
Step-by-step explanation:
This is the order because |-2| in absolute value is positive 2 and |11| in absolute value is still positive because you don't change the sign unless the ll was negative in absolute value.

Answer:
112
Step-by-step explanation:
Hey There!
So remember opposite the sides given are corresponding with its opposite angle
So the corresponding angle of segment QO is angle P and the corresponding angle of segment PQ is angle O
Thus meaning that angle P and angle O are equal to 34
Now we want to find angle Q
So remember all of the angles in a triangle add up to equal 180
so we subtract the given angles (34 and 34) from 180 to find the missing angle (angle Q)
180-34-34=112
So we can conclude that angle Q = 112

50 POINTS! QUICKLY Are the pairs of variables x and y the solutions to the equation x^2–2y=7?
1. (5,8)
2. (-1,-3)
3. (-4,-11.5)
4. (1.2, -2.78)
These are all yes and no questions!
Hi there!
[tex]\large\boxed{(5,8) \text{ and } (1.2, -2.78)}}[/tex]
We are given the equation:
x² - 2y = 7
To verify if each ordered pair is apart of the function, we can plug in their respective x and y values:
1. (5)² - 2(8) = 7
25 - 16 = 9 ≠ 7. This is NOT correct.
2. (-1)² - 2(-3) = 7
1 + 6 = 7. This is correct.
3. (-4)² - 2(-11.5) = 7
16 + 23 = 39 ≠ 7. This is NOT correct.
4. (1.2)² - 2(-2.78) = 7
1.44 +5.56 = 7. This is correct.
Thus, only 1 and 4 are the correct answers.
No yes no yes

The graph below shows distance to time for one of Anna's swimming races. What is Anna's average speed.
Will mark brainlest!
Answer:
A.
Step-by-step explanation:
In this case, on each coordinate point, distance/time = 2.
Anna's average speed during the swimming races as shown in the graph is 2 m/s
What is an equation?An equation is an expression used to show the relationship between two or more numbers and variables.
Anna's average speed can be gotten from the slope of the line. The line pass through (0, 0) and (3, 6), hence:
Slope = (6 - 0) / (3 - 0) = 2 m/s
Anna's average speed during the swimming races as shown in the graph is 2 m/s

a student Miss 10 problems on an English test and received a grade of 44%. If all the problems were of equal value, how many problems were on the test
Answer:
Rounded to the nearest integer, the test had 18 problems in all.
Step-by-step explanation:
Given that a student missed 10 problems on an English test and received a grade of 44%, if all the problems were of equal value, to determine how many problems were on the test the following calculation must be performed:
100 - 44 = 56
56 = 10
100 = X
100 x 10/56 = X
1,000 / 56 = X
17.85 = X
Thus, rounded to the nearest integer, the test had 18 problems in all.

find f(2+h) and f(x+h) where h is not equal to 0
Answer:
f(2+h)=-(h+2/3)^2+1/4
f(x+h)=-(x+h-1/2)^2+1/4
Step-by-step explanation:
1. f(2+h)=(2+h)-(2+h)^2=2+h-4-4h-h^2=-h^2-3h-2=-(h^2+3h+2)
=-(h+2/3)^2+1/4
2. Let (x+h)=a, then rewrite the equation into f(a)=a-a^2.
a-a^2=-(a^2-a)=-[(a-1/2)^2-1/4]=-(a-1/2)^2+1/4.
Insert a=x+h, f(x+h)=-(x+h-1/2)^2+1/4
