If all sequences of six characters are equally likely, then the probability that the license plate will contain no duplicate letters or numbers is 0.59.

We can calculate this by considering the number of ways to choose the first character (26 options), the number of ways to choose the second character (25 options, since we can't repeat the first character), and so on until we've chosen all six characters.

The number of such sequences is 26 * 25 * 24 * 23 * 22 * 21 = 26!/(26-6)! = 26!/(20!) = 26 * 25 * 24 * 23 * 22 * 21/6! = 26 * 25 * 24 * 23 * 22 * 21/720 = 308,915,776.

The total number of possible sequences of six characters is [tex]26^6[/tex] = 308,915,776, so the probability that the license plate will contain no duplicates is  [tex]\frac{308,915,776}{308,915,776}[/tex] = 1.

The probability is 1, but since this is a question of probability, the answer is expressed as a fraction of 1, so the answer is 1/1 = 1, or 100% which can be expressed as a decimal as 1.

So the correct answer is d) 0.59.

Answer:

the semiannual interest payment is $153.77 and the total interest earned over the life of the bond is $9,226.20.

Step-by-step explanation:

To find the semiannual simple interest payment, we need to divide the annual interest rate by 2, since there are 2 semiannual periods in a year:

Semiannual interest rate = Annual interest rate / 2

= 6.268% / 2

= 3.134%

To find the semiannual interest payment, we multiply the face value of the bond by the semiannual interest rate:

Semiannual interest payment = Face value x Semiannual interest rate

= $4900 x 3.134%

= $153.77 (rounded to two decimal places)

To find the total interest earned over the life of the bond, we need to multiply the semiannual interest payment by the number of semiannual periods in the bond's life. Since the bond has a 30-year term and 2 semiannual periods in a year, the bond has a total of 60 semiannual periods:

Total interest earned = Semiannual interest payment x Number of semiannual periods

= $153.77 x 60

= $9,226.20 (rounded to two decimal places)

Therefore, the semiannual interest payment is $153.77 and the total interest earned over the life of the bond is $9,226.20.

The units digit of any integer that is the sum of two fourth powers must be 0, 1, 2, 5, 6, or 7.

Let n be an integer that can be written as a sum of two fourth powers. Then, n = a4 + b4, for some integers a and b. We can write n as n = 10k + c, where k is an integer and c is the units digit of n.

We want to show that the units digit of n must be either 0, 1, 2, 5, 6, or 7. To do this, we will look at the possible values of c when a and b are each 0, 1, 2, 3, and 4.

When a = 0 and b = 0, c = 0. When a = 0 and b = 1, c = 1. When a = 0 and b = 2, c = 4. When a = 0 and b = 3, c = 9. When a = 0 and b = 4, c = 6.

When a = 1 and b = 0, c = 1. When a = 1 and b = 1, c = 0. When a = 1 and b = 2, c = 7. When a = 1 and b = 3, c = 6. When a = 1 and b = 4, c = 5.

When a = 2 and b = 0, c = 4. When a = 2 and b = 1, c = 7. When a = 2 and b = 2, c = 0. When a = 2 and b = 3, c = 3. When a = 2 and b = 4, c = 2.

When a = 3 and b = 0, c = 9. When a = 3 and b = 1, c = 6. When a = 3 and b = 2, c = 3. When a = 3 and b = 3, c = 0. When a = 3 and b = 4, c = 7.

When a = 4 and b = 0, c = 6. When a = 4 and b = 1, c = 5. When a = 4 and b = 2, c = 2. When a = 4 and b = 3, c = 7. When a = 4 and b = 4, c = 0.

Thus, when a and b are each 0, 1, 2, 3, and 4, c can only be 0, 1, 2, 5, 6, or 7. Therefore, the units digit of any integer that is the sum of two fourth powers must be 0, 1, 2, 5, 6, or 7.

Assuming the wealthy, generous and whimsical friend chooses the k recipients uniformly at random, there are nCk ways to select the k people from the n who show up at the party.

The number of ways that you and your best friend can both receive iPhones is equal to the number of ways to select k-2 people from the remaining n-2 people, multiplied by 2 (since you can be selected first or second among the k recipients).

Therefore, the probability that you and your best friend both receive iPhones is: 2 * (n-2Ck-2) / nCk

Simplifying this expression using combinatorial identities, we get: 2 * (n-2Ck-2) / nCk = 2 * [(n-2)! / (k-2)! (n-k)!] / [n! / k! (n-k)!] = 2 * k(k-1) / n(n-1)

a. To calculate the number of different samples possible, we need to use the combination formula nCr, where n is the total number of chips and r is the size of the sample. In this case, n = 140 and r = 5. So the number of different samples possible is 140C5 = 2,268,760.

b. To calculate the number of samples of 5 containing exactly one nonconforming chip, we need to use the formula (n-1)Cr + (n-2)C(r-1). In this case, n = 10 and r = 5. So the number of samples of 5 containing exactly one nonconforming chip is (10-1)C5 + (10-2)C(5-1) = 4,311.

c. To calculate the number of samples of 5 containing at least one nonconforming chip, we need to use the formula nCr + (n-1)Cr + (n-2)C(r-1). In this case, n = 10 and r = 5. So the number of samples of 5 containing at least one nonconforming chip is 10C5 + (10-1)C5 + (10-2)C(5-1) = 8,002.

6/11 is the probability that I cat an English muffin for breakfast.

Let G, C, and E represent the events of selecting granola, cereal, and an English muffin, respectively.

Let P(G), P(C), and P(E) represent the probabilities of selecting granola, cereal, and an English muffin, respectively.

We are given that:

P(E) = 2P(G) (the English muffin is selected twice as often as the granola)

P(E) = 3P(C) (the English muffin is selected three times as often as the cereal)

We can use these relationships to solve for P(G), P(C), and P(E):

P(G) = P(E)/2

P(C) = P(E)/3

P(G) + P(C) + P(E) = 1

Substituting the first two equations into the third equation and solving for P(E), we get:

P(E)/2 + P(E)/3 + P(E) = 1

11P(E)/6 = 1

P(E) = 6/11

The statement is true. Solving a linear system is the same as finding the solution set of the system. The solution set of a linear system can also expressed using a parametric description.

A linear system can be solved by locating a parametric description of the solution set. The set of all vectors that fulfil a linear system is known as the solution set, and we can parametrically define this set by expressing the solutions in terms of one or more parameters.

We can determine the pivot variables and the free variables once the system is in row-echelon form. The remaining equations determine the values of the pivot variables, which are the leading coefficients in the equations.

In conclusion, since both entail discovering the values of the variables that satisfy the system, finding a parametric description of the solution set of a linear system is comparable to solving the system.

Given that, a cone a volume of 37 units³, we need to find the heights for given radii,

We know that, the volume of a cone = π×radius²×height/3

Therefore,

1) If the cone's radius is 1, then its height =

37 = π×1×h/3

h = 37×3/3.14

h = 35.35 units

2) If the cone's radius is 2, then its height =

37 = π×4×h/3

h = 37×3/3.14×4

h = 8.83 units

3) If the cone's radius is 5, then its height =

37 = π×25×h/3

h = 37×3/3.14×25

h = 1.41 units

4) If the cone's radius is 1/2, then its height =  

37 = π×1×h/3×4

Answer:

To evaluate the functions for x = 0, we first need to substitute x with 0 in both functions. Therefore, for f(x), we get f(0) = 3(0)² = 0, and for g(x), we get g(0) = 1.5(2)^0 = 1.5.

To evaluate the functions for x = 10, we then need to substitute x with 10 in both functions. Therefore, for f(x), we get f(10) = 3(10)² = 300, and for g(x), we get g(10) = 1.5(2)^10 = 241.5. Therefore, the answers are f(0) = 0 and g(0) = 1.5, f(10)=300 and g(10)=241.5.

Answer:

Step-by-step explanation:

To evaluate the functions for x = 0 and x = 10, we simply substitute the values of x into the corresponding functions.

f(x) = 3x²

f(0) = 3(0)² = 0

f(10) = 3(10)² = 300

g(x) = 1.5(2)^x

g(0) = 1.5(2)^0 = 1.5(1) = 1.5

g(10) = 1.5(2)^10 ≈ 153.6

Therefore, the values of the functions at x = 0 and x = 10 are:

f(0) = 0 and g(0) = 1.5

f(10) = 300 and g(10) ≈ 153.6

9 * 10 = 90

12x = 90

x = [tex]\frac{90}{12} = \frac{15}{2}[/tex]

Answer:

Step-by-step explanation:

To solve for x in the equation:

3x/10 = 9/4

We can start by multiplying both sides by 10 to eliminate the fraction on the left side:

3x = 10 * (9/4)

Next, we can simplify the right side by multiplying 10 by 9/4:

3x = 22.5

Finally, we can isolate x by dividing both sides by 3:

x = 22.5 / 3

x = 7.5

Therefore, the solution to the equation 3x/10 = 9/4 is x = 7.5.

To calculate real GDP in 2013, we need to use the prices and quantities from 2013, but value them using the prices from the base year (2012). We can use the following formula:

Real GDP = (Quantity of Widgets in 2013 x Price of Widgets in 2012) + (Quantity of Thingamabobs in 2013 x Price of Thingamabobs in 2012)

Real GDP = (10 x 5) + (150 x 1) = $200

GDP price index = (Nominal GDP in 2013 / Real GDP in 2012) x 100

Nominal GDP in 2013 = (Quantity of Widgets in 2013 x Price of Widgets in 2013) + (Quantity of Thingamabobs in 2013 x Price of Thingamabobs in 2013)

Nominal GDP in 2013 = (10 x 6) + (150 x 2) = $360

GDP price index = ($360 / $200) x 100 = 180
