Liz flips a coin 90 times. The coin lands head up 63 times and tails up 27 times. The theoretical probability of the coin landing heads up is ___%.
Answers
Answer:
50%
Step-by-step explanation:
This question asks for the theoretical probability
In order to find theoretical probability, we find how many outcomes are possible, and how likely each action is.
In this case, we are flipping a coin. There are only two possible outcomes of this, which are heads and tails. Each of these are equally likely, so that would mean the theoretical probability of flipping it and it landing heads up is 50%
Answer:
P(head up) = 70%Explanation:
P(head up) = 63/90
P(head up) = 7/10
P(head up) = 70%

Solve the system using addition. Use pencil and paper. Explain why the addition method is a good choice for solving the system. If you wanted to solve for x first, is the addition method still a good choice? Explain.
x-2.5y=12.5
-x+2.3y=11.9
Answers
Answer: the answers are x = -292.5 and y = -122
Step-by-step explanation:
Elimination is combining equations to obtain an equation with just one variable. This is only possible if the coefficients of one variable in both equations are opposed and will cancel each other out when put together. Elimination is most effective when it occurs naturally in the equations, but equations may also be modified to produce typical coefficients by multiplying or dividing equations by a given value. The next step would be to utilize the equation we devised to determine the variable's worth and then insert that value back into the original equation to determine the remaining variable.
For solving the question to find x we have to make the coefficients of y the same. for that, we will multiply the first equation by 2.3 and the second equation by 2.5.
After that, we get the 2 equations as
2.3x-5.75y = 28.75
-2.5x+5.75y = 29.75
then by adding the 2 equations we get
-0.2x = 58.5
and by dividing 58.5 by -0.2 we get
x = -292.5
substituting the value of x in any equations above we get
y = -122

Consider the table:

3 9
Which statements are true? Select all that apply.
The graph of the function will not form a straight line, so it is nonlinear.
The function is not proportional.
The function goes through the origin.
The difference between consecutive output values is a constant.
Answers
Answer:
1st 2nd and 3rd box
Step-by-step explanation:
1. It does not form a straight line because the output is not proportional. (it does not follow a pattern)
2. the line is not proportional because it does not follow a pattern or ratio of any kind (2468 is proportional because it follows the pattern of 2)
3. the origin is the coordinates (0,0) and the table has that labeled in the diagram therefore the graph does go through the origin
4. the output is not constant (output is 0149) because it does not show any sort of pattern. therefore the 4th box is incorrect.

The answer is 1133.33 i got it from go ogle so blame me if i got it wrong blame go ogle can i have Brainliest
Step-by-step explanation:
Answer:
66 2/3
Step-by-step explanation:
The way to solve this is The general volume of a pyramid formula is given as: Volume of a pyramid = 1/3 x base area x height. Where Ab = area of the polygonal base and h = height of the pyramid. Note: The volume of a pyramid varies slightly depending on the polygonal base.
What i did was i first tried to do 17 x 20 x 10 which game 3400 but when i remembered that V=1/3 x base area x height which would be 1/3 x 17 x 20 = 113 1/3 but if the base was 10 it would be 1/3 x 10 x 20 = 66 2/3. so i think the base is 10 and the answer would be 66 2/3
If i am wrong i'm sorry
