The value of the GDP price index in 2013 if its value in 2012 is 100:
a. $200; 180.
GDP calculationTo 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
To calculate the GDP price index in 2013, we need to find the percentage change in the value of all goods and services produced in the economy between 2012 and 2013. We can use the following formula: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

For the given corporate bond, whose annual simple interest rate is provided, find the semiannual simple interest
payment and the total interest earned over the life of the bond. Assume 365 days in a year.
$4900 Company A, 30-year bond, 6.268%
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.
If all sequences of six characters are equally likely, what is the probability that the license plate for a new car will contain no duplicate letters or numbers. a) 0.64 b) 0.28 c) 0.09 d) 0.59
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.

Describe Function?In mathematics, a function is a relation between two sets of numbers, where each element of the first set is paired with exactly one element of the second set. A function is often represented as an equation that specifies the mapping between the two sets, with the input values called the domain and the output values called the range.
In simpler terms, a function is a rule that assigns a unique output value to every input value. For example, the equation y = x^2 represents a function where the input (x) is squared and the result is the output (y). If x = 3, then y = 9. A function can be represented as a table, graph, or equation.
Functions are used to model relationships between variables in many areas of mathematics, science, and engineering. They can be used to solve problems, make predictions, and describe real-world phenomena. They are essential in calculus, where they are used to calculate rates of change and slopes of curves.
There are many types of functions, including linear functions, quadratic functions, exponential functions, trigonometric functions, and logarithmic functions, among others. Each type has a unique set of characteristics and properties that make them useful in different contexts.

g(x)=1.5(2)^x
Enter yours answers in the blanks. Round to the nearest tenth as needed
f(0)=__ and g(0)=__
f(10)=__ and g(10)=__
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

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.

To find x, you cross multiply.
3x * 4 = 12x
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.

A batch of 140 semiconductor chips is inspected by choosing a sample of 5 chips. Assume 10 of the chips do not conform to customer requirements. Round your answers to the nearest integer.
a. How many different samples are possible?
b. How many samples of 5 contain exactly one nonconforming chip?
c. How many samples of 5 contain at least one nonconforming chip?
a.There are 2,268,760 different samples possible, b.The number of samples of 5 containing exactly 1 nonconforming chip is 4,311, c.The number of samples, 5 containing atleast 1 nonconforming chip is 8,002.
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.
