The probabilities in the cells of a two-way table are conditional probabilities. True or false?.
Using the conditional probability concept, it is found that the statement is true, as in a two-way probability table, we find the probability of each event B considering that each event A has happened.
What is Conditional Probability?Conditional probability is the probability of one event happening, considering a previous event. The formula is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.[tex]P(A \cap B)[/tex] is the probability of both A and B happening.P(A) is the probability of A happening.In this problem, considering the definition of conditional probability given above, the statement is true, as in a two-way probability table, we find the probability of each event B considering that each event A has happened.

Answer:
Step-by-step explanation:
Recursive formula
tn = t_n-1 / 4
t2 = t1 / 4
t2 = 10240
t1 = 10240 / 4 = 2560
Explicit formula
tn = 10240 / 4^(n-1)
t4 = 10240 / 4^(4 - 1)
t4 = 10240 / 4^3
t4 = 10240 / 64
t4 = 160
t8 = 10240 / 4^7
t8 = 0,625

Which of the following is an irrational number
Answer:
-7.34 repeating
Step-by-step explanation:
A rational number is described as a number that can be expressed as a fraction or ratio of two integers and -7.34 repeating is the only option that does not fit this description. Repeating decimals can not be rational.
Answer: [tex]-\sqrt{14}[/tex] in the lower right corner
===========================================================
Explanation:
A rational number is any fraction like 2/3 or 7/9. Pick any two integers, divide them, and you get a rational number. Zero cannot be in the denominator.
Based on that, we can see that 129/999 is rational, which is crossed off the list of potential answers.
Furthermore, [tex]\sqrt{16} = 4 = \frac{4}{1}[/tex] is also rational since we can form a fraction of integers. Cross this off the list as well. Always try to simplify the expression as much as possible.
-----------------
When converting a fraction to decimal form, it turns out that any rational number has either two cases:
The decimal terminates or stops (eg: 1/2 = 0.5)The decimal pattern repeats forever (eg: 2/99 = 0.02020202...)This means the number [tex]-7.\overline{34}[/tex] = -7.3434343434... is also rational, which is crossed off the list also.
----------------
The only thing left is [tex]-\sqrt{14}[/tex] which is not rational, and therefore we consider it irrational. We cannot form a fraction of integers to represent this square root value. Note how 14 is not a perfect square.

Answer:
A) domain-(2,3,4,5,6)
range- (2,3,4,5,6)
A=function and passes the vertical line test
B) domain-(-5,-3,-1,1,-1)
range- (1,-1,-3,-5,7)
B= not a function it doesn't pass the vertical line test
Step-by-step explanation:
the domain is the X's or the first number in the line and the range is always the second number A is a function because none of the domains repeat for example there is only one two in a and there is only one three in a if there were two threes then it would have not been a function like B there are two negative ones in the domain and because there are two negative ones in the domain it is not a function and it doesn't pass the vertical line test
Solve −79(x+3)=14 please help me answer
Answer:
[tex]x=-\dfrac{251}{79}[/tex]
Step-by-step explanation:
[tex]-79(x+3)=14[/tex]
To isolate x, we must perform inverse operations on both sides of the equal sign to cancel values out.
First, divide both sides by -79 to get rid of it on the left side of the equation:
[tex]\dfrac{-79(x+3)}{-79}=\dfrac{14}{-79}[/tex]
[tex]x+3=-\dfrac{14}{79}[/tex]
Now, subtract 3 from both sides to isolate x:
[tex]x+3-3=-\dfrac{14}{79}-3[/tex]
[tex]x=-\dfrac{14}{79}-3[/tex]
[tex]x=-\dfrac{251}{79}[/tex]
Hey there!
-79(x + 3) = 14
DISTRIBUTE -79 WITHIN the PARENTHESES
-79(x) - 79(3) = 14
-79x - 273 = 14
ADD 273 to BOTH SIDES
-79x - 273 + 273 = 14 + 273
CANCEL out: -273 + 273 because it gives you 0
KEEP: 14 + 273 because it help solve for the x-value
NEW EQUATION: -79x = 14 + 273
SIMPLIFY IT!
-79x = 251
DIVIDE -79 to BOTH SIDES
-79x/-79 = 251/-79
CANCEL out: -79/-79 because it give you 1
KEEP: 251/-79 because it give you the x-value
NEW EQUATION: x = 251/-79
SIMPLIFY IT!
x = - 3 14/76 or x = - 251/79
Therefore, your answer is:
x = - 3 14/76 or x = - 251/79

The point (x,6) is reflected across the y-axis, translated 2 units right and 4 units down, then dilated by a factor of 2. The point is now located at (8,4) what is x?
Answer:
x = - 2
Step-by-step explanation:
Reflection across the y-axis:
( x , 6 ) ------> ( - x , 6 )
Translation 2 units right and 4 units down:
( - x , 6 ) -------> ( - x + 2 , 6 - 4 ) = ( - x + 2 , 2 )
Dilation by a factor of 2:
( - x + 2 , 2 ) ------> ( ( - x + 2 ) × 2 , 2 × 2 ) = ( 8 , 4 ) ⇒
( - x + 2 ) × 2 = 8
- 2x + 4 = 8
- 2x = 4
x = - 2

Answer:
your answer would be 9753/1000
Step-by-step explanation:
2 1/3-1.5x=12.3
step 1:
to solve for x. You have to add 2 1/3 to 12.3 and get x by itself.
2 1/3+ 12.3= 14.63..
step 2 :
now that you have x by itself you're going to divide both sides by x which is -1.5x.
-1.5x/ -1.5x 14.63/ -1.5 = 9.753
step 3:
to put 9.753 in a fraction get rid of the decimal and put it over 1000 since there are 3 numbers after the decimal point.
so your final answer is 9753/1000

Solve for the value of x
Answer:
x = 50°
Step-by-step explanation:
130 and x are adjacent angles on a straight line and sum to 180° , so
x + 130° = 180° ( subtract 130° from both sides )
x = 50°

The table of values shows a linear relationship between x and y. What is the slope of the line represented by the table of values?
A. -8/5
B. -5/8
C. 8/5
D. 5/8
Answer:
Step-by-step explanation:
-8/5 is the slope of the line represented by the table of values.
What is slope of line?The slope of the line is the ratio of the rise to the run, or rise divided by the run
Slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is,
m=(y₂-y₁)/(x₂-x₁)
Let the two points be
(-7,9) and (-2,1)
x₁=-7,y₁=9,x₂=-2 and y₂=1
Substitute the values in formula.
m=1-9/(-2-(-7))
m=-8/(-2+7)
m=-8/5
Hence -8/5 is the slope of the line represented by the table of values.
