(07.01 MC) (Independent Probability) The number of chips of different colors in Amy's bag is shown below:Compund Probability 8 blue chips 9 pink chips 1 black chip Amy takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Amy takes out a pink chip in both draws? (5 points) Group of answer choices 9 over 18 plus 8 over 17 equals 297 over 306 9 over 18 multiplied by 8 over 17 equals 72 over 306 9 over 18 plus 9 over 18 equals 18 over 18 9 over 18 multiplied by 9 over 18 equals 81 over 324
Answer:
The correct option is:
"9 over 18 multiplied by 9 over 18 equals 81 over 324"
Step-by-step explanation:
The number of chips of different colors in Amy's bag is:
Blue (B): 8
Pink (P): 9
Black (Bk): 1
TOTAL (N): 18
It is provided that Amy selects two chips from the bag with replacement.
Compute the probability that Amy takes out a pink chip in both draws as follows:
P (2 Pink Chips) = P (1st Pink Chip) × P (2nd Pink Chip)
= P (P) × P (P)
= [P (P)]²
[tex]=[\frac{9}{18}]^{2}\\\\=(0.50)^{2}\\\\=0.25[/tex]
Thus, the probability that Amy takes out a pink chip in both draws is 0.25.
The correct option is:
"9 over 18 multiplied by 9 over 18 equals 81 over 324"

g(x) = 4 - 3/2x
f(x) = 1/2x + 3/2
Answer: ( f + g ) ( 2 ). Solution. Step 1. Find ( f + g ) ( x ). Since ( f + g ) ( x ) = f ( x ) + g ( x ) then;. ( f + g ) ( x ) = ( 2x + 1 ) + (x. 2. + 2x – 1 ). = 2x + 1 + x. 2. + 2x – 1. = x. 2. + 4x. Step 2. Find ( f + g ) ( 2 ). To find the solution for ( f + g ) ( 2 ) ... ( f – g ) ( 2 ) = 3 (2) – 6.

f(x,y) = (x + y)(xy + 1)
Answer:
(x,y) = (-1, 1), (1, -1) area critical points
f(xx) =2y, fyy =2x,f(xy) =2x + 2y, D = f(xx)fyy - f(xy² )
at (-1, 1)
f(xx) = 2 ,fyy =-2,f(xy) = 0, D = -4 < 0 saddle point
at (1, -1)
f(xx) = -2, fyy =2,f(xy) =0, D = -4 < 0 saddle point
Step-by-step explanation:
Given that;
f(x,y) = (x + y)(xy + 1)
f(x,y) =x²y + xy² + x + y
for critical points fx =0 ,fy =0
fx = 2xy + y² + 1 = 0, fy = x² + 2xy + 1 = 0
2xy + y² + 1 = 0, x²+ 2xy + 1 = 0
2xy + y² + 1 - x² - 2xy - 1 = 0
x² = y²
=> x = y, x = -y
2xy + y² + 1 = 0, x = y
2yy + y² + 1 = 0
3y² = -1 , no solution
2xy + y² + 1 = 0, x = -y
-2yy + y² + 1 = 0
=> -y2 + 1 = 0
=> y = -1, y = 1
y = -1 => x = 1, y = 1 => x = -1
(x,y) = (-1, 1), (1, -1) area critical points
f(xx) =2y, fyy =2x,f(xy) =2x + 2y, D = f(xx)fyy - f(xy² )
at (-1, 1)
f(xx) = 2 ,fyy =-2,f(xy) = 0, D = -4 < 0 saddle point
at (1, -1)
f(xx) = -2, fyy =2,f(xy) =0, D = -4 < 0 saddle point

By some miracle, a Smudgy Press book is found to have 90% of its pages free of typographic errors. Assuming that the distribution of the typographical errors per page is Poisson, what is the probability that a randomly selected page contains exactly one error
Answer:
The value is [tex]P(X = 1 ) = 0.0948[/tex]
Step-by-step explanation:
From the question we are told that
The the probability that the Smudgy Press book pages have zero errors [tex]p = 0.90[/tex]
Gnerally the probability distribution for Poisson distribution is
[tex]P(X = x) = \frac{\lambda ^x * e^{-\lambda}}{x!}[/tex]
Gnerally the probability that the Smudgy Press book pages have zero errors is mathematically represented as
[tex]P(X = 0) = \frac{\lambda ^0 * e^{-\lambda}}{0!} =p= 0.90[/tex]
=> [tex]e^{-\lambda} =p= 0.90[/tex]
taking natural log of both sides
[tex]ln (e^{-\lambda}) = ln(0.90)[/tex]
=> [tex]-\lambda = -0.1054[/tex]
=> [tex]\lambda = 0.1054[/tex]
Generally the probability that a randomly selected page contains exactly one error is mathematically represented as
[tex]P(X = 1 ) = \frac{\lambda ^1 * e^{-\lambda}}{1!}[/tex]
=> [tex]P(X = 1 ) = \frac{0.1054 ^1 * e^{-0.1054 }}{1!}[/tex]
=> [tex]P(X = 1 ) = 0.0948[/tex]

Find TWO numbers if their difference is 16 and their ratio is 5:7.
Answer:
Step-by-step explanation:
their difference is 16
x - y = 16
⇒ x = 16 + y
their ratio is 5:7
x/y = 5/7
substitute:
(16 + y)/y = 5/7
16 + y = (5y)/7
112 + 7y = 5y
2y = -112
y = -56
x - y = 16, so x - -56 = 16,
x+56 = 16
x = 16-56
x = -40

What percentage of adults in high‑income countries are overweight or obese? (Enter you answer rounded to one decimal place.)
Answer:
66%
Step-by-step explanation:
According to a study conducted by the World Health Organization, 66% of adults in high-income countries are overweight. Even though the exact reason for this is not known, there are two main theories. The first one is that individuals make more money and therefore have extra income to spend on food, mainly junk food such as snacks, ice cream, candy, etc. The second theory is that due to the large number of work hours that individuals in these countries have to put in, they tend to eat more often at fast food places such as McDonald's and Burgerking.

Problem: The length of a rectangle is 3cm more than twice its width. If the perimeter is
60cm, find its length.
Answer:
16.5cm
Step-by-step explanation:
[tex]perimeter = 2(l + w)\\l = 3 + w\\perimeter = 60\\2(l + w) = 60\\sub (l = 3 + w) for - l\\2((3+w) + w) = 60\\2(3 + w + w) = 60\\2(3 + 2w) = 60\\6 + 4w = 60\\4w = 60 - 6\\4w = 54\\w = \frac{54}{4}\\w = 13.5\\\\substitute- w= 13- into 2(l = 3 + w)\\l = 13.5 + 3\\l = 16.5[/tex]

2x - 2y = 6
Answer:
y=x-3
Step-by-step explanation:
x varies inversely as y², and x = 6 when y = 8. Find x when y = 2.
Answer:
x=96
Step-by-step explanation:
Since x varies inversely as [tex]y^{2}[/tex], x*[tex]y^{2}[/tex] = k
sub x=6, y=8 into x[tex]y^{2}[/tex] = k => 6*64 = k => k= 384
so when y =2, x = 384/ ([tex]2^{2}[/tex]) = 384/4 = 96

What are polynominal function? Can you please explain in a easy way to understand thank you
Answer:
A polynomial function is a relationship that provides a value that is determined by a polynomial for each input value.
Explanation:
A polynomial is a mathematical expression constructed with constants and variables using the four operations:
Polynomial Example Degree
Constant 1 0
Linear 2x+1 1
Quadratic 3x2+2x+1 2
Cubic 4x3+3x2+2x+1 3
Quartic 5x4+4x3+3x2+2 x+1 4
In other words, we have been calculating with various polynomials all along. When two polynomials are divided it is called a rational expression.
In such cases you must be careful that the denominator does not equal zero. Division by zero is not defined and thus x may not have a value that allows the denominator to become zero. Otherwise, any other value may be substituted for x.
Example
x3−x6−x
x must not have the value of 6 since 6-6=0.

You have space in your garden for 60 small flowering bulbs. Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.85 each. Your budget allows you to spend $39.00 on bulbs. How many crocus bulbs and how many daffodil
The question is incomplete:
You have space in your garden for 60 small flowering bulbs. Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.85 each. Your budget allows you to spend $39.00 on bulbs. How many crocus bulbs and how many daffodil bulbs can you buy?
Answer:
You can buy 20 crocus bulbs and 40 daffodil bulbs.
Step-by-step explanation:
From the information provided you can write the following equations:
x+y=60 (1)
0.25x+0.85y=39 (2), where:
x is the number of crocus bulbs and y is the number of daffodil bulbs.
First, you can solve for x in (1):
x=60-y (3)
Then, you can replace (3) in (2):
0.25(60-y)+0.85y=39
15-0.25y+0.85y=39
0.60y=39-15
y=24/0.60
y=40
Finally, you can replace the value of y in (3) to find the value of x:
x=60-40
x=20
According to this, the answer is that you can buy 20 crocus bulbs and 40 daffodil bulbs.
