Independent-samples t test. This test is used to compare the means of two independent groups. The correct answer is a.

In this case, the average number of matching characteristics reported by the fingerprint analysts and the average number of matching characteristics calculated by the defense attorney. The standard deviation of s = 1.2 would be used in the calculation of the t-statistic.
To determine whether the average number of matching characteristics the defense attorney observed (M = 9.8) differs significantly from that reported by fingerprint analysts (16 matching characteristics), she should use a "Single-sample t test".
Here's why:
- The defense attorney is comparing a sample (her 30 cases) to a known population mean (16 matching characteristics).
- The standard deviation of the sample is provided (s = 1.2), but the population standard deviation is not known.
- An Independent-samples t test would be used if comparing two independent groups, which is not the case here.

The Boolean duality principle is a fundamental concept in Boolean algebra which states that any statement or expression in the algebra can be transformed into an equivalent form by interchanging the roles of AND and OR operators, as well as 0's and 1's.

The Boolean duality principle, also known as De Morgan's laws, is a fundamental concept in Boolean algebra that states that every Boolean expression remains valid if you perform the following steps:
1. Swap AND (⋅) operators with OR (+) operators and vice versa.
2. Replace all 1's with 0's and all 0's with 1's.
3. Complement (invert) all variables.
In other words, the Boolean duality principle allows us to derive a dual expression from an original Boolean expression by applying these transformations. This principle is useful in simplifying Boolean expressions and designing digital circuits.

The possible number of times the binary search algorithm splits the list when searching for a term in the list varies depending on the length of the list and the position of the term within the list.

However, in general, the number of times the list is split during the binary search algorithm is proportional to the logarithm of the length of the list. So, for example, if the list has 8 items, the binary search algorithm may split the list up to 3 times (log base 2 of 8 is 3), while if the list has 1024 items, the binary search algorithm may split the list up to 10 times (log base 2 of 1024 is 10).

We can easily identify the dependent and independent (free) variables by looking at the matrix after converting augmented matrix.

When we convert the augmented matrix of a system of equations into reduced row-echelon form, we can easily identify the dependent and independent (free) variables by looking at the matrix. The columns that contain leading 1's correspond to the variables that are dependent on the others. The columns that do not contain leading 1's correspond to the variables that are independent or free.

For example, if we have a matrix in reduced row-echelon form that looks like this:

1 0 2 | 3
0 1 -1 | 2
0 0 0 | 0

We can see that the first and second columns have leading 1's, so the variables corresponding to those columns (in this case, x1 and x2) are dependent on each other. The third column does not have a leading 1, so the variable corresponding to that column (in this case, x3) is independent or free.

In general, we can say that the number of independent variables is equal to the number of columns without leading 1's, and the number of dependent variables is equal to the number of columns with leading 1's. By identifying the dependent and independent variables, we can then use this information to solve the system of equations using substitution or elimination.

False. The slope of the line is actually -0.5.

Let's determine the slope of the line that passes through the points (20, 5) and (10, 10). To find the slope, we can use the formula:

Slope (m) = (y2 - y1) / (x2 - x1)

Plugging in the coordinates of the two points, we get:

m = (10 - 5) / (10 - 20) = (5) / (-10) = -1/2

The domain will be all real numbers and the range will be all real numbers greater than or equal to 1.

The domain of a function is the set of all possible input values that can be used as arguments for the function. In this case, there are no restrictions on the input values of x, so the domain is all real numbers.

Domain: All real numbers

Range:

To find the range of the function, we can complete the square to rewrite the function in vertex form:

f(x) = x^2 + 10x + 26

f(x) = (x + 5)^2 + 1

Since the square of a real number is always nonnegative, the minimum value of the function is 1, which occurs when x = -5. Therefore, the range of the function is all real numbers greater than or equal to 1.

(a) To approximate P(15 < ΣXi < 22), we can use the Central Limit Theorem (CLT) since we have a large enough sample size (n = 30) and the mean and variance of the Poisson distribution are both finite.

First, we need to find the mean and variance of the sample mean, which is also the mean and variance of the Poisson distribution:

μ = λ = 2/3

σ^2 = λ = 2/3

Next, we can standardize the random variable Z = (ΣXi - nμ) / sqrt(nσ^2) to have a standard normal distribution:

Z = (ΣXi - 30(2/3)) / sqrt(30(2/3)) = (ΣXi - 20) / sqrt(20)

Then, we can use a standard normal table or calculator to find the probability:

P(15 < ΣXi < 22) ≈ P(-2.74 < Z < -1.77) ≈ 0.038

Therefore, the approximate probability is 0.038.

(b) To approximate P(21 < ΣXi < 27), we can use the same method with the CLT.

First, we need to find the mean and variance of the sample mean:

μ = λ = 2/3

σ^2 = λ = 2/3

Next, we can standardize the random variable Z = (ΣXi - nμ) / sqrt(nσ^2) to have a standard normal distribution:

Z = (ΣXi - 30(2/3)) / sqrt(30(2/3)) = (ΣXi - 20) / sqrt(20)

Then, we can use a standard normal table or calculator to find the probability:

P(21 < ΣXi < 27) ≈ P(-0.68 < Z < 0.68) ≈ 0.495

Therefore, the approximate probability is 0.495.

This suggests that there is enough evidence to support the alternative hypothesis, indicating that the average fuel economy today is greater than 21.17 MPG.

Based on the given information, the null hypothesis (H₀) states that the average fuel economy is less than or equal to 21.17 MPG (μ ≤ 21.17), while the alternative hypothesis (H₁) states that the average fuel economy is greater than 21.17 MPG (μ > 21.17). You conducted a one-sample mean hypothesis test and observed a p-value of 0.0427.
To conclude at the 5% level of significance (α = 0.05), you compare the p-value to the significance level. Since the p-value (0.0427) is less than the significance level (0.05), you reject the null hypothesis.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[tex]\Longrightarrow x^2y''+4xy'-4y=0 \ where \ a=1, \ b=4, \ and \ c=-4[/tex]

The characteristic equation:

[tex]\Longrightarrow (1)m^2+(4-1)m+(-4)=0 \Longrightarrow \boxed{m^2+3m-4=0}[/tex]

Solve for "m."

[tex]\Longrightarrow m^2+3m-4=0 \Longrightarrow (m-1)(m+4)=0 \Longrightarrow \boxed{m=1,-4}[/tex]

Note that m's are distinct and real.

[tex]Thus, \ \boxed{y=c_1x+c_2x^{-4}} \therefore Sol.[/tex]

Where the arbitrary constants c_1 and c_2 can be solved for given an initial condition.

The correct answer is option (e) [tex]$y = c_1 x + c_2 x^2$[/tex].

We can use the Cauchy-Euler equation to find the general solution of the given differential equation. The Cauchy-Euler equation is given by:

In the given differential equation, we have [tex]$a_2 = 1$[/tex], [tex]$a_1 = 4$[/tex], and [tex]$a_0 = -4$[/tex]. Therefore, the Cauchy-Euler equation becomes:

[tex]$x^2 y^{\prime \prime}+4 x y^{\prime}-4 y=0$[/tex]

We assume a solution of the form [tex]$y=x^r$[/tex]. Substituting this into the differential equation, we get:

[tex]$$x^2 r(r-1) x^{r-2}+4 x r^1 x^{r-1}-4 x^r=0$$[/tex]

Simplifying, we get:

[tex]$$\begin{aligned}& r(r-1)+4 r-4=0 \\& r^2+3 r-4=0 \\& (r+4)(r-1)=0\end{aligned}$$[/tex]

So, we have two roots[tex]$r_1 = -4$[/tex] and [tex]$r_2 = 1$[/tex]. Therefore, the general solution of the differential equation is:

[tex]$y=c_1 x^{-4}+c_2 x^1$[/tex]
