The probability that exactly two of the dice are odd is 3/8
What is probability?"It is finding out the possibilities of the occurrence of an event."
Formula to find the probability of an event:"P(A) = n(A) / n(S)
where, n(A) is the number of favorable outcomes of an event A
n(S) is the total number of outcomes for an experiment"
What is Binomial theorem of probability?[tex]P=~ ^nC_r\times p^r \times q^{n-r}[/tex]
where, p is the probability of success and q is the probability of failure
For given example,
We roll three six sided dice.
We need to find the probability that exactly two of the dice are odd
the probability of success i. e. dice is odd would be,
⇒ p = 3/6
⇒ p = 1/2
So, the probability of failure would be,
⇒ q = 1 - p
⇒ q = 1 - 1/2
⇒ q = 1/2
Also, n = 3 and r = 2
Using Binomial distribution the required probability would be,
[tex]\Rightarrow P=~ ^nC_r\times p^r \times q^{n-r}\\\\\Rightarrow P=~ ^3C_2\times (\frac{1}{2} )^2 \times (\frac{1}{2} )^{3-2}\\\\\Rightarrow P =\frac{3!}{3!(3-2)!}\times \frac{1}{4} \times \frac{1}{2}\\\\ \Rightarrow \bold{P=\frac{3}{8}}[/tex]
Therefore, the probability that exactly two of the dice are odd is 3/8

One car dealer sells a car with a $500 down payment and payments of $250 per month. Another car dealer sells the same type of car with no down payment and monthly payments of $300 per month. After how many months will the buyers have paid the same amount? Use m for your variable
Answer:
By month 10 both buyers will have paid the same amount of 3,000.
Step-by-step explanation:
The equation would be 500 + 250m = 300m. If you put 10 in for m you get the same amount on both sides of the equation.
500 + 250m = 300m
500 + 250(10) = 300(10)
500 + 2,500 = 300(10)
3,000 = 300(10)
3,000 = 3,000
You play a game with a friend they pul a marble out of the bag with 3 red marbles and 7 green marbles. If the marble is red you win$2 if the marble is green you lose $1 What is the expected value of the game for you
Answer:
Step-by-step explanation:
Amount of red marbles = 3red
Amount of green marbles = 7 green
If the marble is red and you win $2, the total amount of money won = 3 * $2 = $6
If the marble is green and you loose $1, the total amount of money lost = 7 * $1 = $7
The expected value of the game for you = amount won - amount lost
= $6 - $7
= -$1
This means the expected value is a loss of $1

A line contains points M(1, 3) and N(5, 0). What is the slope of MN?
Answer:
-3/4
Step-by-step explanation:
y2-y1/x2-x1
0-3/5-1
A line contains points M(1, 3) and N(5, 0). The slope of MN is -3/4.
What is the slope of the line?A line's slope provides information on the steepness and direction of the line. By calculating the difference between the coordinates of the two locations, (x1,y1) and (x2,y2), it is simple to calculate the slope of a straight line between them.
The slope, m, of the line, is calculated through the equation,
The formula used to find the slope is,
m = (y2 - y1)/ (x2 - x1)
Where (x1, y1) and (x2, y2) are the points
The given points on the line are:
M(1, 3) and N(5, 0)
Substituting it in the formula,
m = (0 - 3)/ (5 - 1)
m = -3/4
Therefore, the slope of MN is -3/4.

Jody decides to ride her bike from her house to the park. The distance she travels on her bike, in kilometers, is equal to the function f(t), where t represents the number of hours she has been riding her bike. Jody rides her bike from her house to the park. Before Jody leaves her house f(0) = 0, and when Jody reaches the park f(2) = 30. From the information given, determine whether each statement is a correct interpretation that can be made about Jody's bike ride. Select Correct or Incorrect for each statement. Correct Incorrect It takes Jody 2 hours to bike to the park. The park is located 2 kilometers from Jody's house. When Jody is at her house she has biked for 0 hours.
Answer:
A)It takes Jody 2 hours to bike to the park.- Correct
B)The park is located 2 kilometers from Jody's house.- Incorrect
C) When Jody is at her house she has biked for 0 hours.- Correct
Step-by-step explanation:
We are given that The distance she travels on her bike, in kilometers, is equal to the function f(t), where t represents the number of hours she has been riding her bike.
f(t)= Distance covered in t hours
t = time in hours
Jody rides her bike from her house to the park. Before Jody leaves her house f(0) = 0
So, Distance covered in 0 hours is 0 km
So, When Jody is at her house she has biked for 0 hours
Jody reaches the park f(2) = 30.
So, Distance traveled in 2 hours is 30 km
So, It takes 2 hours to reach park
A)It takes Jody 2 hours to bike to the park.- Correct
B)The park is located 2 kilometers from Jody's house.- Incorrect

Answer:
Your answer is : A) w = -7/2z
Step-by-step explanation:
Hope this helped : )
Option A is correct, the value of w is -7/2z in the equation 5w+9z=2z+3w.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 5w+9z=2z+3w
In the given equation w and z are the variables.
As per the question we need to solve for w which means we have to find the value of w
Take the like terms on one side by adding -3w-9z on both sides
5w+9z-3w-9z=2z+3w-3w-9z
2w=-7z
Now Divide both sides by two
w=-7/2z
Hence, Option A is correct, the value of w is -7/2z in the equation 5w+9z=2z+3w.

What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
Given,
A certain company are that you must be at least 18 years of age
Let x be the age of employees.
x must be at least 18 years of age.
x≥18

Answer:
g(3)=31.5-3
Step-by-step explanation:
first you want to find g(1) or g(x). all you have to do for this is divide every number by two, since 2/2 is 1.
g(1)=10.5-1
now to find g(30 you just multiply it all by 3.
g(3)=(10.5-1)*3
g(3)=31.5-3.

The prostate-specific antigen (PSA) test is a simple blood test to screen for prostate cancer. It has been used in men over 50 as a routine part of a physical exam, with levels above 4 ng/mL indicating possible prostate cancer. The test result is not always correct, sometimes indicating prostate cancer when it is not present and often missing prostate cancer that is present. Suppose that these are the approximate conditional probabilities of a positive (above 4 ng/ml) and negative test result given cancer is present or absent. In a large study of prostate cancer screening, it was found that about 6.2% of the population has prostate cancer. Draw a tree diagram for selecting a person from this population (outcomes: cancer present or absent) and testing his blood (outcomes: test positive or negative).
The missing table for the Test Result can be expressed as:
Test Result
Positive Negative
Cancer Present 0.21 0.79
Cancer Absent 0.06 0.94

9514 1404 393
Answer:
an extraneous solution
Step-by-step explanation:
A solution that shows up as a result of the process of solving an equation, but that does not work in the original equation, is called "an extraneous solution".

Additional comment
Radical and rational expression equations can have extraneous solutions. For radical equations, they are typically ones that require a negative square root (or negative root of even index). For rational expression equations, they typically involve "excluded" values, values that make a denominator be zero.
Divide. Reduce the awnser to lowest terms 5 2/3 divided by 3 1/9
Answer:
1 23/28
Step-by-step explanation:
turn both of your numbers into fractions: 17/3 and 28/9
to turn you equation into something that you can simplify, flip one of your fractions and that will turn the division sign into a multiplication sign:
17/3 x 9/28
you can simplify this by simplifying 9 to 3 and 3 to 1.
this means you now have 17 x 3/28
multiply 17 and 3 together since they are the numerators, you should get 51/28
now turn this into a mixed fraction: 1 23/28
