Answer:
probability = 0.5294
1) what i know is that there are two machines
2) the probability of choosing a machine that pays 20% of the time
3) expected answer = 0.5294 = 52.94%
4) buy making some assumptions while making the calculations
5) yes
Step-by-step explanation:
Given data:
Number of machines = 2
Assuming probability of machine 2 = 20% = 0.20
Assuming probability of machine 1 = 10% = 0.10
since both machines have the ability to be generous i.e. pay 20% all the time
P( machine 1 is generous ) = P( machine 2 is generous ) = 0.5
this is since there are only two machines
hence find the probability that the chosen machine ( machine 1 ) is the generous machine after the player losses its first bet
P ( Machine 1 is generous | first bet lost )
= [tex]\frac{P( machine 1 is generous n lost) }{p(lost)}[/tex] = [tex]\frac{(1-p(pays|machine 1 is generous))*p(machine 1 is generous)}{[((1-0.10)*0.5)+ ((1-0.20)*0.5)]}[/tex]
= [tex]\frac{(1-0.10)*0.5}{0.85}[/tex] = 0.5294
This the probability that Machine 1 is generous after the player losses the first bet
1) what i know is that there are two machines
2) the probability of choosing a machine that pays 20% of the time
3) expected answer = 0.5294 = 52.94%
4) buy making some assumptions while making the calculations
5) yes

HEY!! remember that if a number has ^2, it basically means it's multiplied by itself. for example:
5^2 = 5 x 5
aka, 25.
You can use this to check each of the answers in your formula, like this:
if x=6, then:
x^2 < 100
6 x 6 = 36
36 < 100
A is one of your correct answers!
Also remember, if you multiply a negative by a negative, it becomes positive.
-5 x -5 = 25
-10 x -10 = 100

Step-by-step explanation:
A landscaper needs to estimate the amount of material required for a project building a circular brick patio for a client. The diameter of the patio is 13m and one bundle of brick will cover 116ft^2. How many bundles does he need?
Answer:
13 bricks
Step-by-step explanation:
Given parameter:
Diameter of the patio = 13m
Area of one bundle of brick = 116ft²
Unknown:
The number of bricks that will cover the patio = ?
Solution:
To solve this problem, we must find the area of the patio first.
Area of the patio = π r²
r is the radius of the patio;
Radius = [tex]\frac{13}{2}[/tex]
So area = π x ( [tex]\frac{13}{2}[/tex]) ² = 132.75m²
Now, let us convert the Area of the brick from ft² to m²;
1ft² = 0.093m²
116ft² = 0.093 x 116 = 10.79m²;
The number of bricks required to cover the patio = [tex]\frac{132.75}{10.79}[/tex] = 12.3 bricks,
Realistically, about 13 bricks would be needed.
The average of 5 distinct scores has the same value as
the median of the 5 scores. The sum of the 5 scores is
420. What is the sum of the 4 scores that are NOT the
median?
Answer: 336 is the sum of the non-median scores
Step-by-step explanation: if the sum of 5 scores is 420, the average is 420/5 = 84
That is also the median to be subtracted: 420-84= 336

prove cosec 2x + cot 2x = cot x
csc(2x) + cot(2x) = 1 / sin(2x) + cos(2x) / sin(2x)
csc(2x) + cot(2x) = (1 + cos(2x)) / sin(2x)
csc(2x) + cot(2x) = (1 + cos(2x)) / (2 sin(x) cos(x))
csc(2x) + cot(2x) = cos²(x) / (sin(x) cos(x))
csc(2x) + cot(2x) = cos(x) / sin(x)
csc(2x) + cot(2x) = cot(x)

Mary is twice as old as Helen’s age, If 8 is subtracted from Helen’s Age and 4 is added to Mary Age? Mary will be 4 times as old as Helen. What are the ages
Answer:
set mary is x years old, and helen is y years old.
first sentence:x=2y
second one:4(y-8)=x+4
bring x=2y in 4(y-8)=x+4
=>4y-32=2y+4
=>2y=36
=>y=18
=>x=36
mary:36
helen:18
We want to write and solve a system of equations that models given situation. We will see that Helen is 18 years old, and Mary is 36 years old.
Let's define the variables we will be using.
m = Mary's age.h = Helen's age.We know that "Mary is twice as old as Helen’s age"
Then:
m = 2*h
"If 8 is subtracted from Helen’s Age and 4 is added to Mary Age, Mary will be 4 times as old as Helen."
(m + 4) = 4*(h - 8)
Then the system of equations is:
m = 2*h
(m + 4) = 4*(h - 8)
To solve it, we can replace m by 2*h in the second equation, so we get:
(2h + 4) = 4*(h - 8)
2*h + 4 = 4*h - 32
4 + 32 = 4*h - 2*h
36/2 = h = 18
And we know that:
m = 2*h = 2*18 = 36
So Helen is 18 years old, and Mary is 36 years old.

Jade and Jackson are considering a $210,000 mortgage for 30 years at 5.7%. With this information, their monthly payment would be $1218.84.
If they make only the minimum payment each month, what is the total payback of this loan?
How much of this total payback is interest?
Answer:
Jade and Jackson
The total payback of this loan = $438,782.72
The interest of this total payback is $228,782.72
Step-by-step explanation:
a) Data and Calculations:
Mortgage = $210,000
Interest rate of mortgage = 5.7%
Monthly payment = $1,218.84
Using an online calculator for Mortgage Payoff, the Original Payoff Schedule is:
Monthly Pay = $1,218.84
Total Payments = $438,782.72
Total Interest = $228,782.72
Answer:
Step-by-step explanation:
1218.84⋅12⋅30=$438,782.40
The total interest paid is the total payback less the amount borrowed.
$438,782.40−$210,000=$228,782.40
