James is a DJ at local radio station. One day, James offers a cash prize to the first caller who correctly answers a rather difficult trivia question. James’ assistant screens and records all incoming calls, and lets James know when the first call with the correct answer has been received; only then does James air the recording of the caller responding correctly. The probability that a randomly selected caller will correctly answer the trivia question is 0.1.
What is the probability that the third caller is the first to correctly answers the question?
0.01
0.0729
0.081
0.09
0.9
Using the inverse binomial distribution, it is found that there is a 0.081 = 8.1% probability that the third caller is the first to correctly answers the question.
The number of callers that correctly answer the question is a binomial variable, however, we want the probability of the third caller being the first to answer the question correctly, hence it is a negative binomial variable.
Inverse binomial:
It is the number of trials until q successes of a binomial variable, with p probability of success.
The probability mass function is:
[tex]P(X = x) = C_{x+q-1,q-1}(1 - p)^xp^q[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
Number of trials until 1 success, hence [tex]q = 1[/tex].0.1 probability of a success on each trial, hence [tex]p = 0.1[/tex].The probability that the third caller is the first to correctly answers the question is P(X = 3), hence:
[tex]P(X = x) = C_{x+q-1,q-1}(1 - p)^xp^q[/tex]
[tex]P(X = 3) = C_{3,0}(0.9)^2(0.1)^1 = 0.081[/tex]
0.081 = 8.1% probability that the third caller is the first to correctly answers the question.

The second statement is the
of the first
A. contradiction
B. converse
C. inverse
D. contrapositive
Answer:
The second statement is the contrapositive of the first.
Step-by-step explanation:
We know that x → y is a conditional statement read as 'if x then q'.
The converse EXCHANGES the hypothesis and conclusion such as:
y → x
The 'contrapositive' statement basically NEGATES the converse of the conditional such as:
¬y → ¬x
Coming back towards the question,
Given
x ⇒ y
¬y ⇒ ¬x
Therefore, the second statement is the contrapositive of the first.
Answer:
D. Contrapositive

Step-by-step explanation:
Alyssa is painting 3 of the walls in her art studio blue. Each of the walls is 8.3 feet tall and 7.5 feet wide. Round the length and width to the nearest whole number (ones). Then estimate the area Alyssa will paint. Write equations to show your work.
Answer: below(=
Step-by-step explanation: Given that,
dimensions of wall = 8.3ft by 7.5ft
height of wall = 8.3
width of wall = 7.5
there are total 3 walls in a bedroom to be painted blue.
Formula to calculate area of one wall
Height x Width
Formula to calculate area of four walls
3 (Height x Width)
= 3( 8.3ft x 7.5ft)
= 3 (62.25 ft²)
= 186.75 ft²
So area Alyssa will paint = 186.75 ft²

In order to join an online learning community, there is a 20$ start up fee and a $5 monthly fee. Write an equation in slope intercept that models this situation
Answer:
y=5x+20
Step-by-step explanation:
The slope equation is usually in the form
y= mx+b
Where "y" is intercept
m= slope
b= constant= 20$ start up fee
Then writing the equation of slope for the question we have y=5x+20 which represent the slope equation.
Natalie and Anjali each improved their yards by planting hostas and shrubs. They bought their supplies from the same store. Natalie spent $86 on 2 hostas and 7 shrubs. Anjali spent $104 on 8 hostas and 4 shrubs. Find the cost of one hosta and the cost of one shrub
Please help it is on solving systems of equation using all methods
Answer: One hosta= $8
One shrub = $10
Step-by-step explanation:
Let the cost of one hostas be h
Let th cost of one shrub be s.
The question can be rewritten into am equation as:
2h + 7s = 86 .......... equation i
8h + 4s = 104 ........ equation ii
Multiply equation i by 8
Multiply equation ii by 2
16h + 56s = 688 ...... equation iii
16h + 8s = 208 ........ equation iv
Subtract equation iv from iii
48s = 480
s = 480/48
s = 10
One shrub cost $10
Put the value of one shrub into equation ii
8h + 4s = 104
8h + 4(10) = 104
8h + 40 = 104
8h = 104 - 40
8h = 64
h = 64/8
h = $8
One hostas cost $8
Identify the terms and like terms in the expression.
2n - n - 4 + 7n
Answer:
8n-4
Step-by-step explanation:
2n-n-4+7n
=2n-n+7n-4
=8n-4
The terms are 2n, - n, - 4 and 7n. The like terms are 2n, -n and 7n
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given the expression as
2n-n-4+7n
WE need to solve the problem first then identify.
=2n-n+7n-4
The terms are 2n, - n, - 4 and 7n
The like terms are those which contain same variable with same degree.
2n, -n and 7n
Now solving the like terms we get;
=8n-4
Hence, The terms are 2n, - n, - 4 and 7n. The like terms are 2n, -n and 7n

Which expressions are equivalent to 5x square root 28x^5+ 8x^3 square root 7x if x>0?
Answer:
1, 2, & 5 in Vertical Order
The expression equivalent to [tex]5x\sqrt{28x^{5} } + 8x^{3} \sqrt{7x}[/tex] is [tex]18x^{3}\sqrt{7x}[/tex].
SimplificationWhat is simplification?In order to simplify an expression, multiple processes must be used to reduce it to a simpler form.
Formula used in simplification:[tex]\sqrt[n]{ab} =\sqrt[n]{a} .\sqrt[n]{b}[/tex]
Simplification of given expression:= [tex]5x\sqrt{28x^{5} } + 8x^{3} \sqrt{7x}[/tex]
= [tex]5x\sqrt{4*7x^{5} } + 8x^{3} \sqrt{7x}[/tex]
= [tex]5x\sqrt{2^{2} *7x^{4}x } + 8x^{3} \sqrt{7x}[/tex]
Apply the simplification formula
= [tex]5x\sqrt{2^{2}} \sqrt{x^{4} } \sqrt{7x} + 8x^{3} \sqrt{7x}[/tex]
= [tex]5x*2x^{2} \sqrt{7x} + 8x^{3} \sqrt{7x}[/tex]
Further solve,
= [tex]10x^{3} \sqrt{7x} + 8x^{3} \sqrt{7x}[/tex]
= [tex]18x^{3} \sqrt{7x}[/tex]
The expression equivalent to [tex]5x\sqrt{28x^{5} } + 8x^{3} \sqrt{7x}[/tex] is [tex]18x^{3}\sqrt{7x}[/tex].
