Answer:
Rounded, 22 yards.
Step-by-step explanation:
The pythagorean theorem states: a^2 + b^2 = c^2
a = 34, squared = 1156
b = 41, squared = 1681
Add those to get 2837.
√2837 = 53.26, rounded.
34 + 41 = 75
75 - 53 = 22
22 yards is your answer.

from the sum of 3x+ 5y -2 and 2x-3y +1 subtract the sum of 4x -8y +3 and -5x + 6y +7
Answer:
First, let's simplify both sums by combining like terms:
3x + 5y - 2 + 2x - 3y + 1 = 5x + 2y - 1
4x - 8y + 3 - 5x + 6y + 7 = -x - 2y + 10
Now we can subtract the second sum from the first:
(5x + 2y - 1) - (-x - 2y + 10) = 5x + 2y - 1 + x + 2y - 10
Simplifying this expression, we get: 6x + 4y - 11
A random sample of 20 observations produced a sample mean of 9.5. Find the critical and observed z-values for each of the following and test each hypothesis at α = 0.05. Write a separate conclusion for each hypothesis. The underlying population standard deviation is known to be 3.5 and the population distribution is normal (5 points):
a. H0: µ = 8.75; H1: µ ≠8.75
b. H0: µ = 8.75; H1: µ > 8.75
a) We fail to reject the null hypothesis at the 5% level of significance. Therefore, the population mean is 8.75
b) We fail to reject the null hypothesis at the 5% level of significance. Therefore, the population mean is 8.75.
Hypothesis Testing:The claim about the population mean under the one-tailed alternative hypothesis and two-tailed alternative hypothesis are tested by the z-test statistic. The critical value approach is used to identify the true statement under the null and the alternative hypothesis at the 5% level of significance.
Sample size , n = 20
Sample mean, x(bar) = 9.5
Population standard deviation, σ = 3.5
a) Null hypothesis: \(H_0:\)μ = 8.75
Alternative hypothesis: \(H_a\) μ \(\neq\) 8.75 Two tailed
Level of significance, α = 0.05
Excel function for the critical value:
=NORMINV(0.05/2,0,1)
\(Z_0_._0_5_/_2\) = ± 1.96
The Z-test statistic is defined as:
Z = x(bar) - μ / σ / \(\sqrt{n}\)
Z = 9.5 - 8.75 / 3.5/\(\sqrt{20}\)
Z = 0.958
The test statistic value is less than the critical value at the 5% level of significance. We fail to reject the null hypothesis at the 5% level of significance. Therefore, the population mean is 8.75.
b) Null hypothesis: \(H_0:\)μ = 8.75
Alternative hypothesis: \(H_a\) μ \(>\) 8.75 Right tailed
Level of significance, α = 0.05
Excel function for the critical value:
=NORMINV(0.05,0,1)
\(Z_0_._0_5_/_2\) = + 1.645
The Z-test statistic is defined as:
Z = x(bar) - μ / σ / \(\sqrt{n}\)
Z = 9.5 - 8.75 / 3.5/\(\sqrt{20}\)
The test statistic value is less than the critical value at the 5% level of significance. We fail to reject the null hypothesis at the 5% level of significance. Therefore, the population mean is 8.75.

Answer:
(x, y) = (-8, 19)
Step-by-step explanation:
9x + 3y = -15
-4x - 3y = -25
(9x + 3y) + ((-4x) - 3y) = -15 + (-25)
5x = -40
x = -8.
So,

The solution to the linear system is unique solution which is x₁ = 1/6, x₂ = 3/2, and x₃ = 17/6.
The correct answer is option A.
To solve the given system of linear equations using elementary row operations and back substitution, let's start by representing the augmented coefficient matrix:
[1 -4 5 | 23]
[2 1 1 | 10]
[-3 2 -3 | -23]
We'll apply row operations to transform this matrix into echelon form:
1. Multiply Row 2 by -2 and add it to Row 1:
[1 -4 5 | 23]
[0 9 -9 | -6]
[-3 2 -3 | -23]
2. Multiply Row 3 by 3 and add it to Row 1:
[1 -4 5 | 23]
[0 9 -9 | -6]
[0 -10 6 | -68]
3. Multiply Row 2 by 10/9:
[1 -4 5 | 23]
[0 1 -1 | -2/3]
[0 -10 6 | -68]
4. Multiply Row 2 by 4 and add it to Row 1:
[1 0 1 | 5/3]
[0 1 -1 | -2/3]
[0 -10 6 | -68]
5. Multiply Row 2 by 10 and add it to Row 3:
[1 0 1 | 5/3]
[0 1 -1 | -2/3]
[0 0 -4 | -34/3]
Now, we have the augmented coefficient matrix in echelon form. Let's solve the system using back substitution:
From Row 3, we can deduce that -4x₃ = -34/3, which simplifies to x₃ = 34/12 = 17/6.
From Row 2, we can substitute the value of x₃ and find that x₂ - x₃ = -2/3, which becomes x₂ - (17/6) = -2/3. Simplifying, we get x₂ = 17/6 - 2/3 = 9/6 = 3/2.
From Row 1, we can substitute the values of x₂ and x₃ and find that x₁ + x₂ = 5/3, which becomes x₁ + 3/2 = 5/3. Simplifying, we get x₁ = 5/3 - 3/2 = 10/6 - 9/6 = 1/6.

if a probability of a single birth resulting in a boy is 51%, what is the probability of a single birth resulting in a girl? (
The probability of a single birth resulting in a girl if the probability of a single birth resulting in a boy is 51% is 49%
Probability is the measure of the likelihood of an event occurring. The probability of an event occurring ranges from 0 to 1. If an event is impossible, the probability of its occurrence is 0, and if the event is certain to occur, the probability is 1. The probabilities of the complement of an event equal one minus the probability of the event. For instance, the probability of the complement of an event A, denoted as A', is 1 - P(A). If the probability of an event A is P(A), then the probability of the complement of A is 1 - P(A).
Here, the probability of a single birth resulting in a boy is 51%. Therefore, the probability of a single birth resulting in a girl is the complement of this event, which is 49%. Hence, the main answer is that the probability of a single birth resulting in a girl if the probability of a single birth resulting in a boy is 51% is 49%.

==========================================================
Reason:
For any triangle, the inside angles always add to 180 degrees.
(angle1)+(angle2)+(angle3) = 180
(6x+13)+(79)+(6x+4) = 180
(6x+6x)+(13+79+4) = 180
12x+96 = 180
12x = 180-96
12x = 84
x = 84/12
x = 7
Then use this to compute angle A.
A = 6x+13 = 6*7+13 = 42+13 = 55 degrees
If you wanted, you can compute the other angle as well
6x+4 = 6*7+4 = 42+4 = 46 degrees
Then as a check:
(angle1)+(angle2)+(angle3) = (55)+(79)+(46) = 180

6. (NO CALC) The function f has a Taylor series about x=1 that converges to f(x) for all x in the interval of convergence. It is known that f(1)=1, f′(1)= −½, and the nth derivative of f at x=1 is given byfⁿ(1)=(-1)ⁿ(n-1)!/2ⁿ for n≥2(d) Show that the approximation found in Part C is within 0.001 of the exact value of f 1.2.
Using Taylor series, the approximation P3(1.2) = 0.77083. Error R3(1.2) < 0.000235. Thus, P3(1.2) - |R3(1.2)| = 0.770599, within 0.001 of f(1.2).
In part C, we found the third-order Taylor polynomial for f about x=1 to be P3(x) = 1 - 1/2(x-1) + 1/8\((x-1)^2\)- 1/48\((x-1)^3\).
To show that this approximation is within 0.001 of the exact value of f(1.2), we need to estimate the error using the remainder term. The remainder term for the third-order Taylor polynomial is given by R3(x) = f(x) - P3(x) = (1/4!)\((x-1)^4\)f⁴(c), where c is some number between 1 and x.
Using the given formula for fⁿ(1), we can compute f⁴(c) = (-1)³(3!)/2⁴ = -3/16. Thus, we have R3(1.2) = (1/4!)\((0.2)^4\)(-3/16) = -0.000234375.
Since R3(1.2) is negative, we know that P3(1.2) > f(1.2), so our approximation is too high. Therefore, to ensure that our approximation is within 0.001 of the exact value of f(1.2), we need to subtract the error bound from our approximation. That is, we need to use P3(1.2) - |R3(1.2)| as our estimate. Substituting values, we get P3(1.2) - |R3(1.2)| = 0.770833333 - 0.000234375 = 0.770598958.
Since |f(1.2) - P3(1.2)| < |R3(1.2)|, we can conclude that our approximation is within 0.001 of the exact value of f(1.2).

At the bank teller's window, arrivals and service times are randomly distributed (Poisson and exponential distributions, respectively). There is only one teller at the window. If the arrival rate is 8 customers per hour, and the service rate is 15 customers per hour, what is the utilization of the teller, as a percentage? (It is a single channel, single server, single phase, unlimited waiting space model). (calculate answer to two decimal places)
The utilization of the teller is approximately 53.33%.
To calculate the utilization of the teller, we need to compare the arrival rate and the service rate. The utilization represents the fraction of time the server (teller) is busy serving customers.
The arrival rate is given as 8 customers per hour, which means that, on average, 8 customers arrive at the teller's window in one hour. This follows a Poisson distribution.
The service rate is given as 15 customers per hour, indicating that, on average, the teller is able to serve 15 customers in one hour. The service times follow an exponential distribution.
Utilization is calculated as the ratio of the arrival rate to the service rate. In other words:
Utilization = Arrival rate / Service rate
Substituting the given values:
Utilization = 8 / 15 ≈ 0.5333
To express this as a percentage, we multiply the result by 100:
Utilization = 0.5333 * 100 ≈ 53.33%
Therefore, the utilization of the teller in this scenario is approximately 53.33%. This means that, on average, the teller is occupied serving customers about 53.33% of the time, and the remaining time is idle or available for serving new customers.

a baseball diamond is a square with side 90 ft. at what rate is the player's distance from home base increasing when he is half way from first to second base?
The rate is his distance from second base decreasing when he is halfway to first base is -45ft
The rate is his distance from third base increasing at the same moment is 26ft
Let's call the batter's distance from second base "x" and his distance from third base "y". We want to find dx/dt (the rate at which x is changing) and dy/dt (the rate at which y is changing) when the batter is halfway to first base.
Since the baseball diamond is a square, we know that the distance from second base to first base is also 90 ft. Therefore, when the batter is halfway to first base, his distance from second base is:
x = 90 ft - 45 ft = 45 ft
Now we can find dx/dt by taking the derivative of x with respect to time:
dx/dt = -26 ft/s
The negative sign indicates that x is decreasing, as we expected.
Next, we need to find the rate at which the batter's distance from third base is increasing when he is halfway to first base. We know that the distance from third base to first base is also 90 ft, so the distance from the halfway point to third base is:
y = 90 ft - 45 ft - 90 ft = -45 ft
Well, in this case, it means that the batter is actually behind third base when he is halfway to first base. So, we need to flip the sign of y to make it positive:
y = -(-45 ft) = 45 ft
Now we can find dy/dt by taking the derivative of y with respect to time:
dy/dt = 26 ft/s
The positive sign indicates that y is increasing, as we expected.

A salesman is paid 3.5% commission on the total sales he makes per month. If he made a total sale of $ 30 000 last month, find the amount of commission he received.
The salesman received a commission of $1,050 based on a 3.5% commission rate for the total sale of $30,000.
To find the amount of commission the salesman received, we can calculate 3.5% of his total sales.
The commission can be calculated using the formula:
Commission = (Percentage/100) * Total Sales
Given:
Percentage = 3.5%
Total Sales = $30,000
Plugging in the values, we have:
Commission = (3.5/100) * $30,000
To calculate this, we can convert the percentage to decimal form by dividing it by 100:
Commission = 0.035 * $30,000
Simplifying the multiplication:
Commission = $1,050
Therefore, the salesman received a commission of $1,050 based on a 3.5% commission rate for the total sale of $30,000.

Assume that demand for a commodity is represented by the equation
P = -2Q-2Q_d
Supply is represented by the equation
P = -5+3Q_1
where Q_d and Q_s are quantity demanded and quantity supplied, respectively, and Pis price
Instructions: Round your answer for price to 2 decimal places and enter your answer for quantity as a whole number Using the equilibrium condition Q_s = Q_d solve the equations to determine equilibrium price and equilibrium quantity
Equilibrium price = $[
Equilibrium quantity = units
The equilibrium price is $0 and the equilibrium quantity is 5 units.
To find the equilibrium price and quantity, we need to set the quantity demanded equal to the quantity supplied and solve for the equilibrium values.
Setting Q_d = Q_s, we can equate the equations for demand and supply:
-2Q - 2Q_d = -5 + 3Q_s
Since we know that Q_d = Q_s, we can substitute Q_s for Q_d:
-2Q - 2Q_s = -5 + 3Q_s
Now, let's solve for Q_s:
-2Q - 2Q_s = -5 + 3Q_s
Combine like terms:
-2Q - 2Q_s = 3Q_s - 5
Add 2Q_s to both sides:
-2Q = 5Q_s - 5
Add 2Q to both sides:
5Q_s - 2Q = 5
Factor out Q_s:
Q_s(5 - 2) = 5
Q_s(3) = 5
Q_s = 5/3
Now that we have the value for Q_s, we can substitute it back into either the demand or supply equation to find the equilibrium price. Let's use the supply equation:
P = -5 + 3Q_s
P = -5 + 3(5/3)
P = -5 + 5
P = 0
Therefore, the equilibrium price is $0 and the equilibrium quantity is 5 units.
