The probability that the weight will be less than 4504 grams is 0.9713.

We need to standardize the value 4504 using the given mean and variance, and then use the standard normal distribution table to find the corresponding probability.

The standard deviation is the square root of the variance: √391876≈626.05

So, the z-score for a weight of 4504 grams is:

z=(4504−3315)/626.05≈1.8974

Using a standard normal distribution table, we find that the probability of a z-score being less than 1.8974 is approximately 0.9713.

We apply the Gram-Schmidt process to these vectors to find an orthonormal basis:

v1 = x1 = [3, -4, 1

To find a basis of the null space N(A), we need to find all vectors x such that Ax = 0, where 0 is the zero vector.

To do this, we set up the augmented matrix [A | 0] and row reduce:

[ 1 2 1 3 2 | 0 ]

[ 4 1 0 6 1 | 0 ]

[ 1 1 2 4 5 | 0 ]

R2 - 4R1 -> R2:

[ 1 2 1 3 2 | 0 ]

R3 - R1 -> R3:

[ 1 2 1 3 2 | 0 ]

[ 0 -7 -4 6 -7 | 0 ]

[ 0 -1 1 1 3 | 0 ]

R2 / -7 -> R2:

[ 0 1 4/7 -6/7 1 | 0 ]

[ 0 -1 1 1 3 | 0 ]

R1 - 2R2 - R3 -> R1:

[ 0 0 0 0 0 | 0 ]

[ 0 1 4/7 -6/7 1 | 0 ]

[ 0 0 11/7 -1/7 1 | 0 ]

We can write the system of equations corresponding to this row echelon form as:

x2 + (4/7)x3 - (6/7)x4 + x5 = 0

(11/7)x3 - (1/7)x4 + x5 = 0

Solving for the variables in terms of the free variables x3, x4, and x5, we get:

x1 = -[(4/7)x3 - (6/7)x4 - x5]/2

x2 = -(4/7)x3 + (6/7)x4 - x5

x3 = x3 (free variable)

x4 = x4 (free variable)

x5 = x5 (free variable)

So the null space N(A) is the set of all vectors of the form:

x = [ -[(4/7)x3 - (6/7)x4 - x5]/2, -(4/7)x3 + (6/7)x4 - x5, x3, x4, x5 ]

To find an orthogonal basis for N(A), we can use the Gram-Schmidt process. Let's call the columns of A a1, a2, a3, a4, and a5.

First, we need to find a basis for N(A) by setting the free variables to 1 and the others to 0:

x1 = [3, -4, 1, 0, 0]

x2 = [-2, 3, 0, 1, 0]

x3 = [-2, 1, 0, 0, 1]

Answer:

To solve this problem, we can use a proportion.

Let x be the change of water in 12 weeks.

We know that in 7 weeks, the water decreased by 9 5/8 pints.

So, we can set up the proportion:

9 5/8 pints / 7 weeks = x / 12 weeks

To solve for x, we can cross-multiply and simplify:

9 5/8 pints * 12 weeks = 7 weeks * x

115 1/2 pints = 7 weeks * x

x = 115 1/2 pints / 7 weeks

x = 16 1/2 pints per 12 weeks

Answer:

i) The horizontal and vertical components of the softball's motion can be described by the following parametric equations:

x(t) = v0x * t

y(t) = v0y * t - 1/2 * g * t^2 + h0

where v0x and v0y are the initial horizontal and vertical velocities, respectively, g is the acceleration due to gravity (32.2 ft/s^2), h0 is the initial height (5 ft), and t is time.

We can find v0x and v0y by resolving the initial velocity vector into horizontal and vertical components:

v0x = v0 * cos(45°) = 49 ft/s * cos(45°) ≈ 34.65 ft/s

v0y = v0 * sin(45°) = 49 ft/s * sin(45°) ≈ 34.65 ft/s

Substituting these values into the parametric equations, we get:

x(t) = 34.65 * t

y(t) = 34.65 * t - 16.1 * t^2 + 5

ii) The softball will be in the air until it hits the ground, which occurs when y(t) = 0. We can solve for t using the quadratic formula:

16.1 * t^2 - 34.65 * t + 5 = 0

t ≈ 2.19 s (rounded to two decimal places)

Therefore, the softball was in the air for approximately 2.19 seconds.

iii) The horizontal distance traveled by the softball can be found by evaluating x(t) at the time when the softball hits the ground:

x(2.19) ≈ 75.8 ft (rounded to one decimal place)

Therefore, the softball traveled approximately 75.8 feet in the air.

iv) The softball reaches its maximum height when its vertical velocity is zero. We can find the time when this occurs by setting v0y - g * t = 0 and solving for t:

t = v0y / g = 34.65 / 32.2 ≈ 1.08 s (rounded to two decimal places)

Therefore, the softball reaches its maximum height after approximately 1.08 seconds.

v) The maximum height reached by the softball can be found by evaluating y(t) at the time when the softball reaches its maximum height:

Let A be the event that the boy cries wolf and B be the event that there is a wolf. We are given the following probabilities:

P(A|B) = 0.8 (the probability that the boy cries wolf when there is a wolf)

P(A|B') = 0.4 (the probability that the boy cries wolf when there is no wolf)

P(B) = 0.25 (the probability that there is a wolf)

We want to find P(B|A), the probability that there really is a wolf given that the boy cries wolf.

We can use Bayes' theorem to calculate this:

P(B|A) = P(A|B) * P(B) / [P(A|B) * P(B) + P(A|B') * P(B')]

Substituting the given values, we get:

P(B|A) = 0.8 * 0.25 / [0.8 * 0.25 + 0.4 * 0.75] = 0.54

Therefore, the probability that there really is a wolf when the boy cries wolf is 0.54.

To plot points along the portion of the firm's short-run supply curve that corresponds to prices where there is positive output, we need to identify the portion of the graph where the firm is producing output.

We can observe from the graph that the firm's short-run supply curve is the component of the marginal cost curve that is higher than the average variable cost curve. The company will shut down and create no production if prices fall below the minimum point of the average variable cost curve. However, as long as the price is above the marginal cost of production, the company will create output at prices above the minimum point of the average variable cost curve.

We may use the orange square symbols to represent the price and matching amount provided at each point where the company is generating output to plot points along this segment of the short-run supply curve. We may advance up the marginal cost curve from the last point of the average variable cost curve until we reach the maximum price at which the company is generating output. The firm's short-run supply curve may then be created by marking each price and quantity combination along this segment of the curve.

It is important to note that the firm's short-run supply curve is a reflection of its marginal cost curve above the average variable cost curve, and will shift as the firm's costs of production change or its technology improve.

Using the Law of Sines, we can solve the given triangle with B = 52, C = 15, and b = 43. The three angles of the triangle are approximately A = 112.94°, B = 52°, and C = 15°, and the lengths of the sides opposite these angles are approximately a = 28.29, b = 43, and c = 8.11.

The Law of Sines states that in any triangle, the ratio of the length of a side to the sine of its opposite angle is the same for all sides and their opposite angles. Therefore, we can use the Law of Sines to solve the given triangle as follows

sin(A)/a = sin(B)/b = sin(C)/c

We are given B = 52, C = 15, and b = 43, so we can use the Law of Sines to find a

sin(A)/a = sin(B)/b

sin(A)/a = sin(52)/43

sin(A) = a sin(52)/43

a = 43 sin(A)/sin(52)

Similarly, we can use the Law of Sines to find c

sin(A)/a = sin(C)/c

sin(A)/a = sin(15)/c

sin(15)c = a sin(A)

c = a sin(A)/sin(15)

Now, we can substitute the expressions for a and c into the equation sin(A)/a = sin(B)/b and solve for sin(A)

sin(A)/(43 sin(A)/sin(52)) = sin(52)/43

sin(A) = (43 sin(52) sin(15))/c

Substituting the expression for c, we get

sin(A) = (43 sin(52) sin(15))/(a sin(A)/sin(15))

Simplifying, we get

sin²(A) = (43²sin²(52) sin²(15))/(a²sin²(A))

Multiplying both sides by a^2 sin^2(A), we get

a²sin⁴(A) = 43^2 sin²(52) sin²(15)

Taking the square root of both sides and solving for a, we get

a = √((43² sin₂(52) sin²(15))/(sin⁴A)))

Substituting the given values and solving for A, we get

a = 28.29 (approx)

A = 112.94° (approx)

c = 8.11 (approx)

Therefore, the three angles of the triangle are approximately A = 112.94°, B = 52°, and C = 15°, and the lengths of the sides opposite these angles are approximately a = 28.29, b = 43, and c = 8.11.

The decay constant $k$ can be found by using the given information that each lake is replaced by clean water every 8 hours. This means that the half-life of the pollutant is 8 hours, which gives us:

[tex]0.5A_0 &= A_0e^{-k(8)} \\ln(0.5) &= -8k \k &= -\frac{\ln(0.5)}{8} \approx 0.08664\end{align*}[/tex]

Substituting this value of k into the equations we derived earlier, we get:

[tex]t_{50} = \frac{\ln(0.5)}{-k} \approx 8.006 \text{ hours}[/tex]

[tex]t_{5} &= \frac{\ln(0.05)}{-k} \approx 22.133 \text{ hours}[/tex]

Therefore, it would take approximately 8 hours to reduce the pollution level in each lake to 50% of its original level, and approximately 22 hours to reduce it to 5% of its original level.

The housing supply function is given by h(I,R) = a log1 + bR + cR log1. The housing supply responds to changes in I with a rate of a, and to changes in R with a rate of b + c log1.

Based on the given equation, the housing supply (h) is determined by two variables: I and R. The equation shows that h is a function of R, with a log-linear relationship. The variable I only appears as a constant (a) in the equation, so changes in I do not directly affect the supply of houses.
On the other hand, changes in R (or OR, which is the same variable) do affect the supply of houses. Specifically, an increase in R leads to an increase in the supply of houses. The magnitude of this increase depends on the values of b and c in the equation.
To see this, we can take the partial derivative of h with respect to R:
dh/dR = b + cR/(ln(10))
This equation tells us how much the housing supply changes in response to a change in R. The derivative is positive (i.e. the supply increases) as long as c is positive. The larger c is, the greater the increase in supply for a given increase in R.
Therefore, the correct answer is:
b + cR/(ln(10))
