Could you use a Paired t-Test to determine if there is a difference between the means of the 2 groups. Type YES or NO
Answers
A paired t-test can be used to determine if there is a difference between the means of the two groups.
YES.
A paired t-test is appropriate for determining if there is a significant difference between the means of two groups when the data is paired or dependent. This test compares the means of two related samples to evaluate if the difference between them is statistically significant.
In a paired t-test, each observation in one group is paired or matched with a corresponding observation in the other group. The test examines the difference between the paired values and determines if that difference is significantly different from zero.
By calculating the t-statistic and comparing it to the critical values from the t-distribution, along with the degrees of freedom, we can assess if there is a significant difference between the means of the two groups.
Therefore, a paired t-test can be used to determine if there is a difference between the means of the two groups.

Find the inverse of the matrix: A = 4 2 3 2 Step 1: Calculate the determinant: 4 2 3 2 =
Answers
The inverse of the matrix A by getting its determinant value is equal to \(A^{-1} = \left[\begin{array}{ccc}1&-1\\\frac{-3}{2} &2\end{array}\right]\)
The matrix is equal to,
A = \(\left[\begin{array}{ccc}4&2\\3&2\end{array}\right]\)
To find the inverse of a matrix,
we first need to calculate its determinant of the matrix A we have,
|A| = \(\left|\begin{array}{ccc}4&2\\3&2\end{array}\right|\)
⇒ |A| = 4(2) - 2(3)
= 8 - 6
= 2
Now we can proceed to find the inverse of A.
Set up the matrix of cofactors.
The matrix of cofactors C is obtained by replacing each element of A with its corresponding cofactor,
which is the determinant of the submatrix obtained by deleting the row and column that contain that element.
For our matrix A, we have,
C = \(\left[\begin{array}{ccc}2&-3\\-2&4\end{array}\right]\)
Transpose the matrix of cofactors.
The transpose of a matrix is obtained by flipping its rows and columns. For our matrix C, we have.
\(C^{T} = \left[\begin{array}{ccc}2&-2\\-3&4\end{array}\right]\)
Divide by the determinant.
The inverse of A is obtained by dividing the transpose of the matrix of cofactors by the determinant of A.
For our matrix A, we have,
A⁻¹ = \(C^{T}\) / |A|
\(C^{T} = (1/2)\left[\begin{array}{ccc}2&-2\\-3&4\end{array}\right]\)
\(C^{T} = \left[\begin{array}{ccc}1&-1\\\frac{-3}{2} &2\end{array}\right]\)
Therefore, the inverse of the matrix A is equal to \(A^{-1} = \left[\begin{array}{ccc}1&-1\\\frac{-3}{2} &2\end{array}\right]\)

A teaching hospital in South-West Part of Nigeria receives on the average 5 pregnant women with high blood pressure per week. What is the probability that on a particular week, the teaching hospital will receive:
1.) No high BP pregnant woman
Answers
Answer:
The probability that on a particular week, the hospital will receive on high BP pregnant woman is 0.0068
Step-by-step explanation:
We use the Exponential distribution,
Since we are given that on average, 5 pregnant women with high blood pressure come per week,
So, average = m = 5
Now, on average, 5 people come every week, so,
5 women per week,
so, we get 1 woman per (1/5)th week,
Hence, the mean is m = 1/5 for a woman arriving
and λ = 1/m = 5 = λ
we have to find the probability that it takes higher than a week for a high BP pregnant woman to arrive, i.e,
P(X>1) i.e. the probability that it takes more than a week for a high BP pregnant woman to show up,
Now,
P(X>1) = 1 - P(X<1),
Now, the probability density function is,
\(f(x) = \lambda e^{-\lambda x}\)
And the cumulative distribution function (CDF) is,
\(CDF = 1 - e^{-\lambda x}\)
Now, CDF gives the probability of an event occuring within a given time,
so, for 1 week, we have x = 1, and λ = 5, which gives,
P(X<1) = CDF,
so,
\(P(X < 1)=CDF = 1 - e^{-\lambda x}\\P(X < 1)=1-e^{-5(1)}\\P(X < 1)=1-e^{-5}\\P(X < 1) = 1 - 6.738*10^{-3}\\P(X < 1) = 0.9932\\And,\\P(X > 1) = 1 - 0.9932\\P(X > 1) = 6.8*10^{-3}\\P(X > 1) = 0.0068\)
So, the probability that on a particular week, the hospital will receive on high BP pregnant woman is 0.0068

Soleil and Malvin each work a job. Soleil starts with $700 and makes $100 per day. Malvin starts out with $200 and makes $120 per day. After how many days will they have at least $5000 all together?
Answers
Answer:
Soleil and Malvin would have $ 5,000 all together after 13 days.
Step-by-step explanation:
Since Soleil and Malvin each work a job, and Soleil starts with $ 700 and makes $ 100 per day while Malvin starts out with $ 200 and makes $ 120 per day, to determine after how many days will they have at least $ 5000 all together it must be done the following calculation:
5,000 - 700 - 200 = 4,100
200X + 120X = 4,100
320X = 4,100
X = 4,100 / 320
X = 12.8
So Soleil and Malvin would have $ 5,000 all together after 13 days.

What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The initial height of the rainwater measured = y₁
The value of y₁ = 24.83 inches
The final height of the rainwater measured = y₂
The value of y₂ = 12.08
The change in height = y₁ - y₂
Substituting the values in the equation , we get
The change in height = 6.75
The number of days = 5 2/5 days
The number of days = 27/5 days = 5.4 days
So , the equation will be
The average change in the height of the rainwater = change in height / number of days
Substituting the values in the equation , we get
The average change in the height of the rainwater = 6.75 / 5.4
The average change in the height of the rainwater = 1.25 inches per day
Hence , the average change is 1.25 inches per day

A 2 meter television camera at ground level is filming the lift-off of a space shuttle at a point 750 meters from the launch pad. The camera’s angle of elevation to the shuttle is 32° at this specific time . Find the height of the shuttle.
Answers
To find the height of the shuttle, we can use trigonometry and the concept of similar triangles. The height of the shuttle is approximately 468.675 meters.
Let's assume that the height of the shuttle is represented by 'h' meters. From the information given, we know that the distance between the camera and the launch pad is 750 meters, and the angle of elevation from the camera to the shuttle is 32 degrees.
Using trigonometry, we can set up the following equation:
tan(32°) = h / 750
To find the value of h, we can rearrange the equation:
h = tan(32°) * 750
Using a calculator, we can find the value of tan(32°) ≈ 0.6249.
Now we can calculate the height of the shuttle:
h ≈ 0.6249 * 750
h ≈ 468.675 meters
Therefore, the height of the shuttle is approximately 468.675 meters.

37.5w + 155.95 = 455.95; where w = 8; signifies the number of weeks required to babysit the business in order to purchase the gaming chair.
How do equations work?A mathematical formula that connects two expressions with the equals sign (=) expresses the equality of the two expressions. For instance, in English, an equation is any properly stated formula that consists of two expressions linked by the equals sign, whereas in French, an equation is described as containing one or more variables. To solve a variable equation, identify the values of the variables that cause the equality to hold true. The answer is known as the values of the variables that must satisfy the equality.
