What can you predict regarding the probability of the coin landing heads up?
--------------------------------------------------------------------------------------------
A.The frequency does not change with more trials.
B.The experimental probability increases with more trials.
C.With more trials, the frequency of heads up will equal the frequency of tails up.
D.The frequency of heads up decreases with more trials.
Answers
Answer:
B
Step-by-step explanation:
the frequency will change for each trial so a is wrong
b yea the probability should increase for either head or tail as the experiment progresses
c it will be impossible to get the frequency of head to equal the frequency of tails
d this is a 49/51 chance depending on what side did it flip on so while the frequency could increase the frequency could also decrease
the answer is B
I'm from your other question asking for help lmæo. and besides who flips that many coins

Does x < 4 mean the same thing as 4 > x
Answers
Answer:
Yes
Step-by-step explanation:
In the first case, x < 4 simply says x is less than 4, while in the second case 4 > x means that 4 is greater than x. Either way we can understand that 4 is greater than x. So, both x < 4 and 4 > x mean the same thing.
Yes,
In mathematics, an algebraic expression is an expression built up from integer constants, variables, and algebraic operations (addition, subtraction, multiplication, division, and exponentiation by an exponent that is a rational number).[1] For example, 3x2 − 2xy + c is an algebraic expression. Since taking the square root is the same as raising the power 1/2, is also an algebraic expression.
By contrast, transcendental numbers like π and e are not algebraic, since they are not derived from integer constants and algebraic operations. Usually, Pi is constructed as a geometric relationship, and the definition of e requires an infinite number of algebraic operations.
A rational expression is an expression that may be rewritten to a rational fraction by using the properties of the arithmetic operations (commutative properties and associative properties of addition and multiplication, distributive property, and rules for the operations on the fractions). In other words, a rational expression is an expression that may be constructed from the variables and the constants by using only the four operations of arithmetic. Thus, is a rational expression, whereas is not.
A rational equation is an equation in which two rational fractions (or rational expressions) of the form are set equal to each other. These expressions obey the same rules as fractions. The equations can be solved by cross-multiplying. Division by zero is undefined, so that a solution causing formal division by zero is rejected.

7) 12

Have a great night!!
Answer:
1) = 2
2) =- -5 as workings show -20/4 = -5/1 = -5
3) = undefined we show equation x = 8
4) = 2/7
5) = undefined we show equation as y=6
6) = undefined as workings show 12/3 = 4/3 positive
7) = 12 as workings show 24/2 = 12/1
We use the formula y2-y1 / x2-x1
As we enter a value say - 4 up on y1
or - 4 up on x1
Then it becomes - - (two subtractions together) they become plus = positive + and either one has a negative sign in front.
if used as second order in bold in formula.
