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

Find the zeros of the function.
Enter the solutions from least to greatest.
f (x)=(x -3)(2x -8)f(x)=(x−3)(2x−8)
Answer:
The zeroes of the function are: 3 and 4
Step-by-step explanation:
Zeroes of a function are the values on which the function produces zero output. To find the zeroes of a function, the function is put equal zero and the values of the variable are found using the equation. The values of x are the zeroes of the function.
Given function is:
[tex]f(x) = (x-3)(2x-8)[/tex]
Putting the function equal to zero
[tex]f(x) = 0\\(x -3)(2x -8) = 0\\x-3 = 0\\x = 3\\2x-8 = 0\\2x = 8\\\frac{2x}{2} = \frac{8}{2}\\x = 4[/tex]
We get two values for x, x=3 and x=4
Hence,
The zeroes of the function are: 3 and 4

Find the value of "x".
Answer:
x = 4.52984
Step-by-step explanation:
Since the triangle has a right angle you need to use the the trigonometric function cos (theta which is the angle given that isn't 90°) = adjacent / hypotenuse (adjacent is the side close to the angle you're using which is 22° and the hypotenuse is the longest side of the triangle that is in the away from the right angle)
From there you plug in the numbers which now become cos (22°) = 4.2 / x
Then you isolate the x by multiplying it to both sides so it's on the left and divide both sides by cos (22°) which will end you up x = 4.2 / cos (22°)
Then you just divide and you 4.52984

1. More time for studying
2. Possibly change your study habits
3. Make sure that you are learning with the technique that works best for you
Step-by-step explanation:
1. Allow yourself more time to study. If this is a specific subject that you feel that you are struggling in, allow yourself more time in a day to study your notes and prep for classwork, tests, etc. in comparison to your other classes.
2. If you feel that your current studying method(s) is working for you, great! If not, there are so many other methods that may work better for you. There's tons of videos on the internet regarding ways to study, there's internet articles explaining ways, and so many other resources! You may learn new ways to take notes, find the perfect balance of studying and taking breaks, and possibly even new memorization techniques! Just find out what works best for you!
3. Ask yourself what kind of learning method you prefer. If you prefer working in groups, maybe meet up with some friends for a group study session in which you guys can discuss ideas and questions. If you can't meet in person, try a zoom call! If you prefer learning with visual methods, maybe find some videos on the topic with visuals to demonstrate! Try to study with your preferred method of learning as often as you can!
If you have any other questions, just let me know! I'm happy to help and hope these tips help as well! :)

An apprentice baker made 40 liters of 60% sugar syrup instead of 40 liters of 45% sugar syrup. How much syrup should she drain and replace with distilled water so that the resulting solution is 40 liters of 45% syrup? Will award brainliest!
Answer:
10 liters
Step-by-step explanation:
let sugar in x liters of 60 % sugar syrup be equivalent to sugar in 40 liters of 45 % sugar syrup.
x×60 %=40×45%
60x=40×45=1800
x=1800/60=30
40-30=10
so 10 liters of 60 % sugar syrup be replaced with 10 liters of distilled water to make 40 liters of 45 % sugar syrup.
Answer: The baker needs to pour off 10 liters of the solution and replace it with 10 liters of distilled water.
.6(40) = 24. .45(40) = 18 24-18 = 6 6 = .6(10) 10 liters must be substituted.
Step-by-step explanation:
The original 60% solution contains 24 L syrup and 16 L water.
A 45% solution must contain 18 L syrup and 22 L water.
The difference in syrup is 6 L. 10 L of the 60% solution contains 6 L syrup.
After pouring off 10 L, the remaining 30 L will contain 18 L syrup and 12 L water.
By adding 10 L water, the resulting solution is 18 L syrup and 22 L water.
18/40 = .45 which is the desired 45% syrup.

An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL. Find the volume of the object.
Answer:
2.3 mL
Step-by-step explanation:
This is called finding the volume by displacement. By subtracting the final volume and the initial volume you can determine how much the volume changed when the object was added. That change in voulme represents the volume of the object, so in this case:\
14.5-12.2 = 2.3 mL
The change in the volume of the object is, 2.3 mL.
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
We have to given that;
An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL .
Here, An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL .
Hence, The change in the volume of the object is,
⇒ 14.5 - 12.2 mL
⇒ 2.3 mL

The m<1=4x-30 and the m<5=2x+50. Find m<1 and m<7.
A. M<1=130 and M<7=130
B. M<1=130 and M<7=50
C. M<1=50 and M<7=50
D. M<1=50 and M<7=130
Answer:
D) m<1 = 50 m<7 = 130
Step-by-step explanation:
Lets set up the equation!
We know m<4 is 4x-30 and the m<5 is 2x + 50 due to alternate interior angles they are congruent so we can forge an equation, all we do is set them equal to each other!
4x-30 = 2x+50
Add 30 to both sides
4x = 2x +80
Subtract 2x from both sides.
2x = 80
Divide both sides by 2
x = 40
Now that we know x we can just plug it into the expression of m<4 to find m<1
4x-30
4(40)-30
80 - 30
50
m<4 = 50
Because m<1 and m<4 are vertical angles they are congruent!
m<1 = 50
We also know m<4 and m<5 are congruent so m<5 = 50 as well.
Because <7 is supplementary to <5 we know that the sum of both angles amount to 180.
x represents m<7
50 + x = 180
Now we solve by subtraction 50 from both sides
x = 130
m<7 = 130

A baseball team has a record of 47 wins and 39 losses, then they have to win 44 games in a row so that their winning percentage will be above 70%. Hence, option E is correct.
What is the percentage?The Latin term "per centum," which signifies "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentage are fractions. To put it another way, it's the relationship here between component and a whole, in which the value of the whole is always assumed to be 100. A specific portion or amount in each hundred is referred to as the percentage. The fraction is denoted by the sign "%," and its denominator is 100.
Finding the proportion of a whole in units of 100 is the goal of percentage calculations. There are two methods to calculate a percentage:
