suppose that diastolic blood pressure readings of adult males have a bell-shaped distribution with a mean of 7979 mmhg and a standard deviation of 88 mmhg. using the empirical rule, what percentage of adult males have diastolic blood pressure readings that are between 7171 mmhg and 8787 mmhg?
95% of adult males have diastolic blood pressure readings that are at least 71 and 87 mmHg
The empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean . The empirical rule is further illustrated below
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations.
From the information given, the mean is 79 mmHg and the standard deviation is 88 mmHg.
2 standard deviations = 2 × 88 = 167
82 + 20 = 102 mmHg
Therefore, 95% of adult males have diastolic blood pressure readings that are at least 102 mmHg.

payments of $1400 each year for 8 years at 6ompounded annually
If you make annual payments of $1400 for 8 years at a 6% interest rate compounded annually, the total amount accumulated over the 8-year period would be approximately $12,350.
To explain further, when you make annual payments of $1400 for 8 years, you are essentially depositing $1400 into an account each year. The interest rate of 6% compounded annually means that the interest is added to the account balance once a year.
To calculate the total amount accumulated, you can use the formula for the future value of an ordinary annuity:
FV = P * ((1 + r)^n - 1) / r
where FV is the future value, P is the payment amount, r is the interest rate per compounding period (in this case, 6% or 0.06), and n is the number of compounding periods (in this case, 8 years).
Plugging in the values, we have:
FV = $1400 * ((1 + 0.06)^8 - 1) / 0.06
≈ $12,350
Therefore, the total amount accumulated over the 8-year period would be approximately $12,350.

In each of the months June, July, and August, the number of accidents occurring in that month is modeled by a Poisson random variable with mean 1. In each of the other 9 months of the year, the number of accidents occurring is modeled by a Poisson random variable with mean 0.5. Assume that these 12 random variables are mutually independent. Calculate the probability that exactly two accidents occur in July through Novembe
Answer:
\(P(X=2)=0.1849\)
Step-by-step explanation:
From the question we are told that
Sample size n=3
Sample mean 1 \(\=x_1=1\)
Sample mean 2 \(\=x_2=0.5\)
Generally the Probability that 2 accidents occurs from July to August is mathematically given by
\(mean\ accidents=2*\=x_1\)
\(mean\ accidents=2*1\)
\(mean\ accidents=2\)
Generally the probability that 2 deaths occurs from September through November is mathematically given by
\(Mean\ accidents=3*\=x_2\)
\(Mean\ accidents=3*0.5\)
\(Mean\ accidents=1.5\)
Therefore
Total Mean accidents \(T_a=2+1.5=>3.5\)
Generally the probability of two accident per month is mathematically given by
\(P(X=2)=\frac{e^-^3^.^5*3.5^2}{2!}\)
\(P(X=2)=0.1849\)
Therefore the probability of having 2 accidents from July through to November is
\(P(X=2)=0.1849\)

Tell whether the following postulate or property of the plane euclidean geometry has a corresponding statement in spherical geometry. explain your reasoning or write the corresponding statement.
1. if two lines form vertical angles, then the angles are equal in measure.
2. if two lines meet a third line at the same angle, those lines are parallel.
3. three lines can form two triangles.
4. three non-parallel lines divide the plane into 7 separate parts.
When two lines form vertical angles, then the angles are equal in measure. This is true.
What is a vertical angle?Vertical angles are angles opposite each other where the two lines cross. When two lines meet a third line at the same angle, those lines are not parallel.
There are no parallel lines in spherical geometry. On the globe, all the lines of longitude meet the equator at the right angle.
Three lines can form two triangles. This is true as three noncollinear points determine the triangle in spherical geometry.

A numerical algorithm is used to solve the following system of equations:
(x1)-(x2)=2
-2(x1)+5(x2)=-1
The numerical results are x1 = 2.96 and x2 = 1.04. The Euclidean norm of the residuals is (to four decimal places):
The Euclidean norm of the residuals is 0.2916
To find the Euclidean norm of the residuals, we first need to calculate the residuals for each equation in the system. The residual of an equation is the difference between the left-hand side (LHS) and the right-hand side (RHS) of the equation.
Given the system of equations:
x1 - x2 = 2 (Equation 1)
-2x1 + 5x2 = -1 (Equation 2)
Let's calculate the residuals:
Residual 1 = LHS of Equation 1 - RHS of Equation 1
= (x1 - x2) - 2
Residual 2 = LHS of Equation 2 - RHS of Equation 2
= (-2x1 + 5x2) - (-1)
Now, substitute the numerical values x1 = 2.96 and x2 = 1.04 into the residuals:
Residual 1 = (2.96 - 1.04) - 2
= 1.92 - 2
= -0.08
Residual 2 = (-2 * 2.96 + 5 * 1.04) - (-1)
= (-5.92 + 5.20) - (-1)
= -0.72 + 1
= 0.28
The Euclidean norm of the residuals is calculated by taking the square root of the sum of the squares of the residuals:
Euclidean norm = sqrt((Residual 1)^2 + (Residual 2)^2)
= sqrt((-0.08)^2 + (0.28)^2)
= sqrt(0.0064 + 0.0784)
= sqrt(0.0848)
≈ 0.2916
Therefore, the Euclidean norm of the residuals, rounded to four decimal places, is approximately 0.2916.

find the absolute maximum and minimum values of the following function on the given set r.
f(x,y) = x^2 + y^2 - 2y + ; R = {(x,y): x^2 + y^2 ≤ 9
The absolute maximum and minimum values of the function f(x, y) = x^2 + y^2 - 2y on the set R = {(x, y): x^2 + y^2 ≤ 9} can be found by analyzing the critical points and the boundary of the region R.
To find the critical points, we take the partial derivatives of f(x, y) with respect to x and y, and set them equal to zero. Solving these equations, we find that the critical point occurs at (0, 1).
Next, we evaluate the function f(x, y) at the boundary of the region R, which is the circle with radius 3 centered at the origin. This means that we need to find the maximum and minimum values of f(x, y) when x^2 + y^2 = 9. By substituting y = 9 - x^2 into the function, we obtain f(x) = x^2 + (9 - x^2) - 2(9 - x^2) = 18 - 3x^2.
Now, we can find the maximum and minimum values of f(x) by considering the critical points, which occur at x = -√2 and x = √2. Evaluating f(x) at these points, we get f(-√2) = 18 - 3(-√2)^2 = 18 - 6 = 12 and f(√2) = 18 - 3(√2)^2 = 18 - 6 = 12.
Therefore, the absolute maximum value of f(x, y) is 12, which occurs at (0, 1), and the absolute minimum value is also 12, which occurs at the points (-√2, 2) and (√2, 2).

To prove the converse of the Vertical Angles Theorem, we need to show that if angles LDBC and LABE are congruent and points D, B, and E are on opposite sides of line AB, then they must be collinear.
Given: ∠LDBC ≅ ∠LABE
To Prove: D, B, and E are collinear
Proof:
1. Assume that points D, B, and E are not collinear.
2. Let BD intersect AE at point X.
3. Since D, B, and E are not collinear, then X is a point on line AB but not on line DE.
4. Consider triangle XDE and triangle XAB.
5. By the Alternate Interior Angles Theorem, ∠XAB ≅ ∠XDE (corresponding angles formed by transversal AB).
6. Since ∠LDBC ≅ ∠LABE (given), we have ∠LDBC ≅ ∠XAB and ∠LABE ≅ ∠XDE.
7. Therefore, ∠LDBC ≅ ∠XAB ≅ ∠XDE ≅ ∠LABE.
8. This implies that ∠XAB and ∠XDE are congruent vertical angles.
9. However, since X is not on line DE, this contradicts the Vertical Angles Theorem, which states that vertical angles are congruent.
10. Therefore, our assumption that D, B, and E are not collinear must be false.
11. Thus, D, B, and E must be collinear. Therefore, the converse of the Vertical Angles Theorem is proven, and we can conclude that if ∠LDBC ≅ ∠LABE and D, B, and E are on opposite sides of line AB, then D, B, and E are collinear.

how many bit strings of length seven either begin with two 0s or end with three 1s?
There are 40 such bit strings.
To count the number of bit strings of length seven that either begin with two 0s or end with three 1s, we need to use the principle of inclusion-exclusion.
Let A be the set of bit strings that begin with two 0s, and let B be the set of bit strings that end with three 1s.
Then, we want to find the size of the set A ∪ B, which consists of bit strings that satisfy either condition.
The size of A can be calculated as follows:
since the first two digits must be 0, the remaining five digits can be any combination of 0s and 1s,
so there are \(2^5 = 32\) possible strings that begin with two 0s.
Similarly, the size of B can be calculated as follows:
since the last three digits must be 1, the first four digits can be any combination of 0s and 1s,
so there are\(2^4 = 16\) possible strings that end with three 1s.
However, we have counted the strings that both begin with two 0s and end with three 1s twice.
To correct for this, we need to subtract the number of strings that belong to both A and B from the total count.
The strings that belong to both A and B must begin with two 0s and end with three 1s, so they have the form 00111xxx,
where the x's can be any combination of 0s and 1s.
There are \(2^3 = 8\) such strings.
Therefore, the total number of bit strings of length seven that either begin with two 0s or end with three 1s is:
|A ∪ B| = |A| + |B| - |A ∩ B| = 32 + 16 - 8 = 40.
