{ Pisces04 }Consider a cupcake shop that sells 7 different kinds of cupcakes (chocolate raspberry, strawberry shortcake, red velvet, funfetti, lemon, German chocolate, and chocolate caramel). Assuming there are at least 12 of each kind available, if Andres asks for a random selection of 12 cupcakes, what is the probability that he will get
(a)exactly 6 red velvet?
(b)exactly 3 each of 4 different kinds?
(c)no lemon?
(d)at least 1 German chocolate and at least one chocolate raspberry?
Answer:
If Andres asks for a random selection of 12 cupcakes, the Probability of choosing:
a)exactly 6 red velvet?
The probability that 6 will be red velvet = 6/12 x 14.3% = 7.2%
(b)exactly 3 each of 4 different kinds?
Since 3 x 4 = 12
The probability that the 12 will be 3 each from 4 different kinds
= 14.3%
(c)no lemon?
Probability of getting a lemon cupcake = 1/7 = 14.3%
Therefore, probability of not getting a lemon cupcake = 100% - 14.3% = 85.7%
(d)at least 1 German chocolate and at least one chocolate raspberry?
The probability of at least 2 being 1 German and 1 chocolate raspberry
= 2/12
= 16.67%
Step-by-step explanation:
a) Probability of each kind of Cupcake

20,000 ten thousands equals how many hundred thousands
20,000 ten thousand equals 2000 Hundred thousand.
As per the question statement, we are provided with a value: "20,000 ten thousand".
We are required to calculate how many hundred thousand are equal to 20,000 ten thousand.
To solve this question, let us first write down 20,000 ten thousand into the numerical format, i.e, \((20000*10,000)=200000000\).
As we know, a hundred thousand when written down in the numerical format becomes 100,000, let us assume that 20,000 ten thousand equals to "x" number of Hundred thousand.
Therefore, we can form a linear equation in one variable "x" based on the condition, in the above-mentioned statement, which goes as \((100,000*x)=200000000\)
\(or, (100,000x)=200000000\\or,x=\frac{200000000}{100,000}\\or,x=\frac{2*10^{8} }{10^5\\}or,x=(2*10^3)\\or,x=2000\)
Hence, 20,000 ten thousands equals 2000 Hundred thousands.

The large jar has better value for money than the smaller one.
Which jar is the best value for money?To see which jar is the best value for the money, we need to take the quotient between the cost of each jar and the size. The smaller that value gets, the best value we have.
For the first jar we have:
q = £4.10/540 = 0.0075
For the second jar we have:
q' = £2.81/360 = 0.0078

Suppose that X and Y are integer valued random variables with joint probability mass function given by pX, Y(a, b) = {1/4a, for 1 > b > a > 4, otherwise. a. Show that this is indeed a joint probability mass function. b. Find the marginal probability mass function of X and Y. c. Find P(X = Y + 1).
The joint probability mass function given by PX, Y(a, b) = {1/4a, for 1≤ b≤a≤4, otherwise is indeed a joint probability mass function because the sum of all the joint probabilities is equal to 1.
To find the marginal probability mass function of X, we need to sum the joint probabilities over all possible values of Y:
PX(a) = ∑ PX, Y(a,b) = ∑ (1/4a) = 1/4
To find the marginal probability mass function of Y, we need to sum the joint probabilities over all possible values of X:
PY(b) = ∑ PX, Y(a,b) = ∑ (1/4a) = 1/4
To find P(X = Y + 1), we need to find the joint probability of X = a and Y = a-1, where a = 2,3.
P(X = Y + 1) = PX, Y(2,1) + PX, Y(3,2) = (1/42) + (1/43) = 1/4 + 3/12 = 5/12
So the probability that X is one more than Y is 5/12.
It's important to note that the given joint probability mass function is valid as it satisfies the non-negativity and the condition of summing to 1.

20ft flag pole has a rope tied from to top to the ground. The rope makes a 35° angle with the ground. How long is the rope?
the length of the rope is approximately 11.9 feet.
What is right angle triangle?
The term "right-angled triangle" refers to any triangle with an internal angle that is either a right angle or 90 degrees in value. The right triangle or the 90-degree triangle are other names for this triangle because of this. Right triangles have "opposite" and "adjacent" sides, which refer to the sides that are across from and next to respective angles, respectively. When a right triangle is formed, the hypotenuse is its longest side.
We can consider the flagpole, the ground, and the rope as forming a right triangle. The angle between the flagpole and the rope is 90 degrees, and the angle between the rope and the ground is 35 degrees. Therefore, the angle between the flagpole and the ground is 90 - 35 = 55 degrees.
Let's call the length of the rope "r". We can use the trigonometric function tangent to find r:
tan(35°) = opposite/adjacent = r/20
Multiplying both sides by 20, we get:
r = 20 tan(35°)
Using a calculator, we get:
r ≈ 11.9 feet
Therefore, the length of the rope is approximately 11.9 feet.

Complete Question
The complete question is shown on the first uploaded image
Answer:
The value is \(T = 51 \ inches \)
Step-by-step explanation:
From the diagram we can obtain the the height of T as follows
\(T = \frac{60 + 42 }{2}\)
Answer:
51 inches
Step-by-step explanation:
By definition of midpoint, 42 through T + T through 60 is congruent to each other.
So, we can add 42+60 together to get the total distance. This is 102.
Next, we divide 102 by 2 because as mentioned since T is the midpoint, each "segment" is exactly 2 halves, they are congruent to each other.
102/2= 51 inches.

Thus, the value of x and y for the given right angled triangle are found as: x = 8 and y = 2√3.
Explain about the Pythagorean theorem:The Pythagorean Theorem, a well-known geometric principle that states that the square just on hypotenuse (the side across from the right angle) of a right triangle equals the sum of the squares on its legs, is also known as the
a² + b² = c².
For the larger triangle, applying Pythagorean theorem:
4² + (4√3)² = x²
x² = 16 + 16*3
x² = 16 + 48
x² = 64
x = 8
Then, x - 6 = 8 - 6 = 2
Now applying Pythagorean theorem for smaller triangle:
y² + (x - 6)² = 4²
y² = 4² - 2²
y² = 16 - 4
y² = 12
y² = √12
y = 2√3
Thus, the value of x and y for the given right angled triangle are found as: x = 8 and y = 2√3.

Let c be a positive number. A differential equation of the form dy/dt=ky^1+c where k is a positive constant, is called a doomsday equation because the exponent in the expression ky^1+c is larger than the exponent 1 for natural growth. An especially prolific breed of rabbits has the growth term My^1.01. If 2 such rabbits breed initially and the warren has 16 rabbits after three months, then when is doomsday?
Answer:
The doomsday is 146 days
Step-by-step explanation:
Given
\(\frac{dy}{dt} = ky^{1 +c}\)
First, we calculate the solution that satisfies the initial solution
Multiply both sides by
\(\frac{dt}{y^{1+c}}\)
\(\frac{dt}{y^{1+c}} * \frac{dy}{dt} = ky^{1 +c} * \frac{dt}{y^{1+c}}\)
\(\frac{dy}{y^{1+c}} = k\ dt\)
Take integral of both sides
\(\int \frac{dy}{y^{1+c}} = \int k\ dt\)
\(\int y^{-1-c}\ dy = \int k\ dt\)
\(\int y^{-1-c}\ dy = k\int\ dt\)
Integrate
\(\frac{y^{-1-c+1}}{-1-c+1} = kt+C\)
\(-\frac{y^{-c}}{c} = kt+C\)
To find c; let t= 0
\(-\frac{y_0^{-c}}{c} = k*0+C\)
\(-\frac{y_0^{-c}}{c} = C\)
\(C =-\frac{y_0^{-c}}{c}\)
Substitute \(C =-\frac{y_0^{-c}}{c}\) in \(-\frac{y^{-c}}{c} = kt+C\)
\(-\frac{y^{-c}}{c} = kt-\frac{y_0^{-c}}{c}\)
Multiply through by -c
\(y^{-c} = -ckt+y_0^{-c}\)
Take exponents of \(-c^{-1\)
\(y^{-c*-c^{-1}} = [-ckt+y_0^{-c}]^{-c^{-1}\)
\(y = [-ckt+y_0^{-c}]^{-c^{-1}\)
\(y = [-ckt+y_0^{-c}]^{-\frac{1}{c}}\)
i.e.
\(y(t) = [-ckt+y_0^{-c}]^{-\frac{1}{c}}\)
Next:
\(t= 3\) i.e. 3 months
\(y_0 = 2\) --- initial number of breeds
So, we have:
\(y(3) = [-ck * 3+2^{-c}]^{-\frac{1}{c}}\)
-----------------------------------------------------------------------------
We have the growth term to be: \(ky^{1.01}\)
This implies that:
\(ky^{1.01} = ky^{1+c}\)
By comparison:
\(1.01 = 1 + c\)
\(c = 1.01 - 1 = 0.01\)
\(y(3) = 16\) --- 16 rabbits after 3 months:
-----------------------------------------------------------------------------
\(y(3) = [-ck * 3+2^{-c}]^{-\frac{1}{c}}\)
\(16 = [-0.01 * 3 * k + 2^{-0.01}]^{\frac{-1}{0.01}}\)
\(16 = [-0.03 * k + 2^{-0.01}]^{-100}\)
\(16 = [-0.03 k + 0.9931]^{-100}\)
Take -1/100th root of both sides
\(16^{-1/100} = -0.03k + 0.9931\)
\(0.9727 = -0.03k + 0.9931\)
\(0.03k= - 0.9727 + 0.9931\)
\(0.03k= 0.0204\)
\(k= \frac{0.0204}{0.03}\)
\(k= 0.68\)
Recall that:
\(-\frac{y^{-c}}{c} = kt+C\)
This implies that:
\(\frac{y_0^{-c}}{c} = kT\)
Make T the subject
\(T = \frac{y_0^{-c}}{kc}\)
Substitute: \(k= 0.68\), \(c = 0.01\) and \(y_0 = 2\)
\(T = \frac{2^{-0.01}}{0.68 * 0.01}\)
\(T = \frac{2^{-0.01}}{0.0068}\)
\(T = \frac{0.9931}{0.0068}\)
\(T = 146.04\)

A mass of a basket with 60 apples was 3 1/5 kg. The mass of an identical basket

Give your answer as a fraction in its simplest form.
The weight of a basket containing 60 apples was 3 1/5 kg. An identical basket containing 40 apples weighed 2 and a half kilograms. It weighs 150 pounds.
Is an apple a gram or kilogram?The typical weight of an apple ranges from 150 g to 250 g. A 10 g error was discovered in the weight of each apple. The average weight of apples is calculated by dividing the total number of apples by the actual weight of the apples. Consequently, 10 apples actually weigh 62 g on average. As an apple is rather little, the measurement should be in grams.
Apples have a high fiber content. About 4 grams, or 17% of the Daily Value, of this vitamin may be found in a single medium-sized apple (100 grams) (DV). We divide the mass of the element in 1 mole of the compound by the compound's molar mass and multiply the result by 100 to determine the mass percent of the element in the compound.

Nelson lands 4650 on 2% interest rate. He plans to pay this after 2 months. What will the total principal and interest payment be?
The total principal and interest payment that Nelson will have to pay after 2 months is $4665.50.
To calculate the total principal and interest payment, we need to determine the interest amount and add it to the principal.
First, let's find the interest amount:
Interest = Principal x Interest Rate x Time
Given:
Principal = $4650
Interest Rate = 2% per year
Time = 2 months
Since the interest rate is given on an annual basis, we need to convert the time from months to years. There are 12 months in a year, so 2 months is equivalent to 2/12 = 1/6 years.
Interest = $4650 x 0.02 x (1/6) = $15.50
Now, we can calculate the total principal and interest payment:
Total Payment = Principal + Interest
Total Payment = $4650 + $15.50 = $4665.50
