Mary earned the following test scores (out of 100 points) on the first four tests in her algebra class: 88 , 94 , 95 , and 92 . Her mean test score is 92.25 What score would Mary need to earn on the fifth test in order to raise her mean test score to 93 ?
Mary needs to score 96 on the fifth test to raise her average test score from 92.25 to 93.
Let's use the formula for the mean
mean = (sum of all scores) / (number of scores)
We can rearrange this formula to solve for the sum of all scores
sum of all scores = mean x number of scores
We know that Mary's mean test score is currently 92.25 and she has taken four tests, so
sum of all scores = 92.25 x 4 = 369
To raise her mean test score to 93, Mary needs the sum of all five test scores to be
sum of all scores = 93 x 5 = 465
To find out what score Mary needs to earn on the fifth test, we can subtract the sum of her first four test scores from the required sum of all five test scores
score on fifth test = sum of all five tests - sum of first four tests
score on fifth test = 465 - 369
score on fifth test = 96
Therefore, Mary needs to earn a score of 96 on the fifth test in order to raise her mean test score to 93.

A line is perpendicular to y = -1/5x + 1 and intersects the point negative (-5,1) what is the equation of this perpendicular line?
Answer: y = 5x + 26
Step-by-step explanation:
To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.
We can use the point-slope form of a linear equation to find the equation of the line:
y - y1 = m(x - x1)
Substituting the values, we get:
y - 1 = 5(x - (-5))
Simplifying further:
y - 1 = 5(x + 5)
Expanding the brackets:
y - 1 = 5x + 25
Rearranging the equation to the slope-intercept form (y = mx + b):
y = 5x + 26
Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.

There are 170 deer on a reservation. The deer population is increasing at a rate of 30% per year
A function \(P(t) = 170.(1.30)^t\) that gives the deer population P(t) on the reservation t years from now
We were told there were 170 stags on reservation. The number of deer is increasing at a rate of 30% per year.
We could see the deer population grow exponentially since each year there will be 30% more than last year.
Since we know that an exponential growth function is in form:
\(f(x) = a*(1+r)^x\)
where a= initial value, r= growth rate in decimal form.
It is given that a= 170 and r= 30%.
Let us convert our given growth rate in decimal form.
\(30 percent = \frac{30}{100} = 0.30\)
Upon substituting our given values in exponential function form we will get,
\(P(t) = 170.(1+0.30)^t\)
⇒ \(P(t)= 170.(1.30)^t\)
Therefore, the function \(P(t) = 170.(1.30)^t\) will give the deer population P(t) on the reservation t years from now.

3. Find the general solution of the partial differential equations: 3x (a) 12uxx 5x2u 4e3 (b) 2uxx-Uxy - Uyy = 0 [7]
The general solution of the given partial differential equations are as follows:
(a) The general solution of the equation 12uxx + 5x^2u = 4e^3 is u(x) = C1/x^5 + C2/x + (4e^3)/12, where C1 and C2 are arbitrary constants.
(b) The general solution of the equation 2uxx - Uxy - Uyy = 0 is u(x, y) = f(x + y) + g(x - y), where f and g are arbitrary functions.
(a) To find the general solution of the equation 12uxx + 5x^2u = 4e^3, we assume a solution of the form u(x) = X(x)Y(y). Substituting this into the equation and dividing by u, we obtain (12/X(x))X''(x) + (5x^2/Y(y))Y(y) = 4e^3. Since the left side depends only on x and the right side depends only on y, both sides must be equal to a constant. Let's call this constant λ. This gives us two separate ordinary differential equations: 12X''(x)/X(x) = λ and 5x^2Y(y)/Y(y) = λ.
Solving the first equation, we find that X(x) = C1/x^5 + C2/x, where C1 and C2 are constants determined by the initial or boundary conditions.
Solving the second equation, we find that Y(y) = e^(√(λ/5)y) for λ > 0, Y(y) = e^(-√(-λ/5)y) for λ < 0, and Y(y) = C3y for λ = 0, where C3 is a constant.
Therefore, the general solution is u(x) = (C1/x^5 + C2/x)Y(y) = C1/x^5Y(y) + C2/xY(y) = C1/x^5(e^(√(λ/5)y)) + C2/x(e^(-√(-λ/5)y)) + (4e^3)/12.
(b) To find the general solution of the equation 2uxx - Uxy - Uyy = 0, we assume a solution of the form u(x, y) = X(x)Y(y). Substituting this into the equation and dividing by u, we obtain (2/X(x))X''(x) - (1/Y(y))Y'(y)/Y(y) = λ. Rearranging the terms, we have (2/X(x))X''(x) - (1/Y(y))Y'(y) = λY(y)/Y(y). Since the left side depends only on x and the right side depends only on y, both sides must be equal to a constant. Let's call this constant λ.
Solving the first equation, we find that X(x) = f(x + y), where f is an arbitrary function.
Solving the second equation, we find that Y(y) = g(x - y), where g is an arbitrary function.
Therefore, the general solution is u(x, y) = f(x + y) + g(x - y), where f and g are arbitrary functions.

The distributor sells those fitting to a large number of customers on a regular basis. Find the probability that the average margin for the distributor is
P(M ≤ $7) = Φ(-1/3√n) where Φ is the standard normal cumulative distribution function (cdf).
Suppose that the amount of margin that a pipe, valve and fitting distributor can make on a specific type of fitting is a random variable with mean $8 and standard deviation of $3.
The distributor sells those fitting to a large number of customers on a regular basis. The probability that the average margin for the distributor is normally distributed is: Normal Distribution
This is because of the following reasons: The pipe, valve and fitting distributor makes sales to a large number of customers on a regular basis.
The Central Limit Theorem (CLT) is the basis of the normal distribution assumption. It's possible to use it since it's a random variable. It is also possible to verify the assumption since the sample size is large. Furthermore, a normally distributed variable has well-known properties, making it easier to calculate probabilities.
Let X be the amount of margin that the pipe, valve and fitting distributor makes on a specific type of fitting.Suppose X ~ N(8, 3²). Let M be the average margin of the distributor.
Then: M ~ N(8, 3/√n)
Where n is the number of fittings sold.
The probability that the average margin is less than or equal to $7 is given by:
P(M ≤ $7)
= P(Z ≤ (7-8)/(3/√n))
= P(Z ≤ -1/3√n) where Z is the standard normal distribution
Therefore, P(M ≤ $7) = Φ(-1/3√n) where Φ is the standard normal cumulative distribution function (cdf).
