Jaoan reads that themass of an average elephant's brain is 3 4/10 kilograms greater than an average man's brain. How many kilograms is an average elephant's brain?

Let x be the number of pinon nuts each animal has collected. To make the chipmunk have ten more pinon nuts than the squirrel, the squirrel would have to give the chipmunk 10 pinon nuts.

So, after the exchange, the squirrel would have x - 10 pinon nuts, and the chipmunk would have x + 10 pinon nuts.

Since they are each giving an equal amount, the total number of pinon nuts remains the same. Therefore, we can set up the equation:

x + (x - 10) = 2x - 10

Simplifying and solving for x, we get:

2x - 10 = 2x

-10 = 0

This is a contradiction, so there is no solution that satisfies the conditions of the problem.

Therefore, the problem is not well-defined and there is no answer.

To evaluate the definite integral of the given function, ∫ (t^5 - 2t^2)/t^4 dt, follow these steps:
1. Simplify the integrand: Divide each term by t^4.
  (t^5/t^4) - (2t^2/t^4) = t - 2t^(-2)

2. Integrate each term with respect to t.
  ∫(t dt) - ∫(2t^(-2) dt) = (1/2)t^2 + 2∫(t^(-2) dt)

3. Apply the power rule to the remaining integral.
  (1/2)t^2 + 2(∫t^(-2+1) dt) = (1/2)t^2 + 2(∫t^(-1) dt)

4. Integrate t^(-1) with respect to t.
  (1/2)t^2 + 2(ln|t|)

Now, since we need to evaluate the definite integral, we should have the limits of integration. Let's assume the limits of integration are a and b. Then, apply the Fundamental Theorem of Calculus:

[(1/2)b^2 + 2(ln|b|)] - [(1/2)a^2 + 2(ln|a|)]

a) The demand function is 134.33e^-0.693p

b) At P = $3, we have elasticity is  0.83, at P = $4, we have elasticity is  1.05, at P = $5, we have elasticity is 1.34.

c) We should sell the cheese at a price of $3.84 per pound to maximize monthly revenue.

d) We should sell the cheese at a price of $4.22 per pound to generate the highest revenue within the timeframe of one month.

a) To construct a demand function of the form q = Ae^-bp, we can use the sales figures for the prices $3 and $5 per pound. First, we calculate the values of A and b:

A = q/p = 403/3 ≈ 134.33

b = ln(q/Ap) / p = ln(403/134.33) / (3-5) ≈ 0.693

Using these values, the demand function becomes:

q = 134.33e^-0.693p

b) To find the price elasticity of demand at each of the prices listed, we can use the formula:

E = (dq/dp) * (p/q)

At P = $3, we have:

E = (dq/dp) * (p/q) = (-134.33 * -0.693 * 3) / 403 ≈ 0.83

At P = $4, we have:

E = (dq/dp) * (p/q) = (-134.33 * -0.693 * 4) / 284 ≈ 1.05

At P = $5, we have:

E = (dq/dp) * (p/q) = (-134.33 * -0.693 * 5) / 225 ≈ 1.34

c) To find the price that will maximize monthly revenue, we can use the formula:

p = (1/b) * ln(A/b)

Plugging in the values of A and b that we calculated earlier, we get:

p = (1/0.693) * ln(134.33/0.693) ≈ $3.84

d) If we only have 200 pounds of cheese and it will spoil in one month, we need to sell it at a price that will generate the highest revenue within that timeframe. To do this, we can use the formula:

R = pq

where R is the revenue, p is the price per pound, and q is the quantity sold. We can express q in terms of p using our demand function:

q = 134.33e^-0.693p

Substituting this into the revenue equation, we get:

R = p * 134.33e^-0.693p

To find the price that will maximize revenue, we can take the derivative of R with respect to p and set it equal to zero:

dR/dp = 134.33e^-0.693p - 93.13pe^-0.693p = 0

Solving this equation numerically, we get:

p ≈ $4.22

This price is different from the price calculated in part (c) because we have a limited quantity of cheese that will spoil, so we need to balance the price and quantity sold to maximize revenue within the given timeframe.

To solve the problem, we first need to graph the equation y = 3 / (√36-9x^2) and find the points where it intersects the x-axis and y-axis.

To find the x-intercept, we set y = 0 and solve for x:
0 = 3 / (√36-9x^2)
0 = 3
This has no solution, which means that the graph does not intersect the x-axis.

To find the y-intercept, we set x = 0 and solve for y:
y = 3 / (√36-9(0)^2)
y = 3 / 6
y = 1/2
So the graph intersects the y-axis at (0, 1/2).

Next, we need to find the point where the graph intersects the vertical line x = 3. To do this, we substitute x = 3 into the equation y = 3 / (√36-9x^2):
y = 3 / (√36-9(3)^2)
y = 3 / (√-243)
This is undefined, which means that the graph does not intersect the line x = 3.

Now we can draw a rough sketch of the graph and the region bounded by the x-axis, the line x = 0, and the curve y = 3 / (√36-9x^2):

           |
    _______|
   /       |
  /        |
 /         |
/_________|
|         |

The area we want to find is the shaded region, which is bounded by the x-axis, the line x = 0, and the curve y = 3 / (√36-9x^2). To find the area, we need to integrate the equation y = 3 / (√36-9x^2) with respect to x from x = 0 to x = 3:

A = ∫(0 to 3) 3 / (√36-9x^2) dx

We can simplify this integral by using the substitution u = 3x, du/dx = 3, dx = du/3:

A = ∫(0 to 9) 1 / (u^2 - 36) du/3

Next, we use partial fractions to break up the integrand into simpler terms:

1 / (u^2 - 36) = 1 / (6(u - 3)) - 1 / (6(u + 3))

So we have:

A = ∫(0 to 9) (1 / (6(u - 3))) - (1 / (6(u + 3))) du/3

A = (1/6) [ln|u - 3| - ln|u + 3|] from 0 to 9

A = (1/6) [ln(6) - ln(12) - ln(6) + ln(6)]

A = (1/6) [ln(1/2)]

A = (-1/6) ln(2)

Therefore, the exact area bounded by y = 3 / (√36-9x^2), x = 0, y = 0, and x = 3 is (-1/6) ln(2).
To find the area bounded by y = 3 / (√36-9x^2), x = 0, y = 0, and x = 3, we can set up an integral to compute the definite integral of the function over the given interval [0, 3]. The integral will represent the area under the curve:

Area = ∫[0, 3] (3 / (√(36-9x^2))) dx

To solve the integral, perform a substitution:

Let u = 36 - 9x^2
Then, du = -18x dx

Now, we can rewrite the integral:

Area = ∫[-√36, 0] (-1/6) (3/u) du

Solve the integral:

Area = -1/2 [ln|u|] evaluated from -√36 to 0

Area = -1/2 [ln|0| - ln|-√36|]

Area = -1/2 [ln|-√36|]

Step-by-step explanation:

To find the experimental probability of a student in Homeroom 203 taking a certain number of minutes to get to school, we need to divide the number of students who take that amount of time by the total number of students in the homeroom.

The total number of students in the homeroom is:

3 + 5 + 10 + 7 + 2 + 3 = 30

The probability of a student taking less than 10 minutes to get to school is:

3/30 = 0.1 or 10%

The probability of a student taking 10-19 minutes to get to school is:

5/30 = 0.166 or 16.6%

The probability of a student taking 20-29 minutes to get to school is:

10/30 = 0.333 or 33.3%

The probability of a student taking 30-39 minutes to get to school is:

7/30 = 0.233 or 23.3%

The probability of a student taking 40-49 minutes to get to school is:

2/30 = 0.066 or 6.6%

The probability of a student taking 50 minutes or more to get to school is:

3/30 = 0.1 or 10%

To make a probability distribution, we can list the possible outcomes (in this case, the time it takes to get to school) and their corresponding probabilities:

Time (min) Probability

Less than 10 0.1

10-19 0.166

20-29 0.333

If p : q = 2/3 : 2 and p : r = 3/4 : 1/2 , the ratio of p : q : r in its simplest form is 32 : 27 : 24.

To calculate the ratio p : q : r, we need to first find the values of p, q, and r. We can use the given proportions to set up a system of equations and solve for the variables.

From the first proportion, we know that:

p/q = 2/3 : 2

We can simplify this by cross-multiplying:

p = (2/3) * 2q

p = (4/3)q

From the second proportion, we know that:

p/r = 3/4 : 1/2

Again, we can cross-multiply and simplify:

p = (3/4) * r/(1/2)

p = (3/2)r

Now we have two equations for p in terms of q and r. We can substitute these into each other and solve for q and r:

(4/3)q = (3/2)r

r/q = (8/9)

q/r = (9/8)

Now we have the ratios of r to q and q to r. We can use these to find the ratio of p, q, and r:

p : q : r = p : q * (9/8) : r * (8/9)

Substituting the values we found for p in terms of q and r:

p : q : r = (4/3)q : q * (9/8) : r * (8/9)

It will take 6 minutes for the water hose to fill the 2-gallon bucket at a rate of 1/3 gallon per minute.

To determine the time required to fill a 2-gallon bucket using a water hose that fills at a rate of 1/3 gallon per minute, you can use a simple calculation.

First, identify the fill rate of the hose, which is 1/3 gallon per minute. Now, consider the bucket's capacity, which is 2 gallons. To find out how many minutes it takes to fill the bucket, divide the total capacity of the bucket by the fill rate:

Time (minutes) = Bucket capacity (gallons) / Fill rate (gallons per minute)

In this case:

Time (minutes) = 2 gallons / (1/3 gallons per minute)

To solve this, you can multiply the numerator and denominator by the reciprocal of the fill rate:

Time (minutes) = 2 gallons * (3 minutes per gallon)

Time (minutes) = 6 minutes

So, it will take 6 minutes for the water hose to fill the 2-gallon bucket at a rate of 1/3 gallon per minute.

Your best friend is charging you an annual interest rate of 4% for lending you ₹300 for nine months with a quarterly interest rate of 1%.

The amount a lender charges a borrower for the use of assets, such as money, consumer goods, or physical assets, is known as an interest rate. It is a fraction of the loan's principal, which is the amount borrowed to cover the cost of the purchase or the deposit made with a bank or other financial institution.

If your best friend is charging you an extra ₹3 for every three months that pass before you return the money, then after nine months, you will owe her an extra ₹9 in addition to the original ₹300.

So the total amount you must pay her if you return the ₹300 after nine months would be ₹309.

To calculate the annual rate of interest she is charging you, we can use the formula:

Annual Interest Rate = (Total Interest / Principal) x (12 / Number of Months)

Where the Principal is the original amount borrowed (₹300), the Total Interest is the extra amount you owe her (₹9), and the Number of Months is the time period for which you borrowed the money (9 months).

Plugging in the values, we get:

Annual Interest Rate = (9 / 300) x (12 / 9) = 0.04 or 4%

The trigonometric ratios of angle C are sin C = 15/17, cos C = 8/17, and tan C = 15/8.

Since triangle ABC is a right triangle with a right angle at B, and we know AC = 17 units (hypotenuse) and BC = 8 units (adjacent side to angle C), we can use the Pythagorean theorem to find the length of the remaining side, AB (opposite side to angle C).

The Pythagorean theorem states: AB² + BC² = AC²

Plugging in the values we know:
AB² + 8² = 17²
AB² + 64 = 289

To find AB:
AB² = 289 - 64 = 225
AB = √225 = 15 units

Now we can determine the trigonometric ratios of angle C:

1. sine (sin C) = opposite/hypotenuse = AB/AC = 15/17
2. cosine (cos C) = adjacent/hypotenuse = BC/AC = 8/17
3. tangent (tan C) = opposite/adjacent = AB/BC = 15/8

So the trigonometric ratios of angle C are:
sin C = 15/17, cos C = 8/17, and tan C = 15/8.

The given differential equation is y"' + 4y = 0. To derive a recurrence relation, we assume that the solution has the form y = e^rx.

Substituting this in the differential equation, we get the characteristic equation r^3 + 4 = 0. Solving this, we get three roots r = -2i, 2i, 0.

So, the general solution is y = c1cos(2x) + c2sin(2x) + c3. Using the initial conditions y(0) = 0 and y'(0) = 1, we get c1 = 0 and c2 = 1/2.

Therefore, the solution is y = 1/2sin(2x) + c3.

Now, we can find the recurrence relation by writing c3 in terms of c2 and c1. We have c3 = y(0) - (1/2)sin(0) = 0. So, the recurrence relation is cn+2 = -4cn.

Using the initial conditions, we have c1 = 0 and c2 = 1/2. Therefore, the explicit formula for the coefficients is cn = (1/2)(-4)^n-2 for n ≥ 2.

Finally, the particular solution can be found by adding the general solution to the homogeneous solution. Since the roots are imaginary, the particular solution will have the form y = Acos(2x) + Bsin(2x).

Substituting this in the differential equation, we get A = 0 and B = -1/8.
So, the particular solution is y = -1/8sin(2x).

Therefore, the final solution in terms of familiar elementary functions is y = (1/2)sin(2x) - (1/8)sin(2x) = (3/8)sin(2x).

The crate can hold 175 bricks.

First, we need to convert the volume of the crate from cubic meters to cubic centimeters because the volume of each brick is given in cubic centimeters.

1 m = 100 cm

Volume of crate = 2.8 m3 = 2.8 x (100 cm)3 = 2,800,000 cm3

Now we can find the number of bricks that can be packed into the crate by dividing the volume of the crate by the volume of each brick:

Number of bricks = Volume of crate / Volume of each brick

= 2,800,000 cm3 / 16,000 cm3

= 175 bricks

Using the Empirical Rule.  The percentage of small business stock prices that are more than $81. 67 is 0.30%

To use the Empirical Rule, we need to assume that the distribution of small business stock prices is approximately normal.

First, we need to find the z-score for $81.67:

z = (81.67 - 54.82) / 8.95 = 2.99

Next, we can use the Empirical Rule to estimate the percentage of small business stock prices that are more than $81.67:

About 99.7% of the data falls within 3 standard deviations of the mean.

Therefore, about 0.3% of the data falls more than 3 standard deviations above the mean.

Since $81.67 is more than 3 standard deviations above the mean, we can estimate that the percentage of small business stock prices that are more than $81.67 is about 0.3%.

Rounded to the nearest hundredth, the estimated percentage is 0.30%.

The MAD for this set of data is 0.8.

To find the MAD (Mean Absolute Deviation) for this set of data, we first need to find the mean of the ages:

Mean = (13 + 10 + 9 + 10 + 10 + 9 + 10 + 10 + 11 + 9) / 10 = 10.1

Next, we find the absolute deviation of each age from the mean:

|13 - 10.1| = 2.9

|10 - 10.1| = 0.1

|9 - 10.1| = 1.1

|10 - 10.1| = 0.1

|10 - 10.1| = 0.1

|9 - 10.1| = 1.1

|10 - 10.1| = 0.1

|10 - 10.1| = 0.1

|11 - 10.1| = 0.9

|9 - 10.1| = 1.1

Then, we find the average of these absolute deviations:

MAD = (2.9 + 0.1 + 1.1 + 0.1 + 0.1 + 1.1 + 0.1 + 0.1 + 0.9 + 1.1) / 10 = 0.8

Therefore,To find the MAD (Mean Absolute Deviation) for this set of data, we first need to find the mean of the ages:

Mean = (13 + 10 + 9 + 10 + 10 + 9 + 10 + 10 + 11 + 9) / 10 = 10.1

Next, we find the absolute deviation of each age from the mean:

|13 - 10.1| = 2.9

|10 - 10.1| = 0.1

|9 - 10.1| = 1.1

|10 - 10.1| = 0.1

|10 - 10.1| = 0.1

|9 - 10.1| = 1.1

|10 - 10.1| = 0.1

|10 - 10.1| = 0.1

|11 - 10.1| = 0.9

|9 - 10.1| = 1.1

Then, we find the average of these absolute deviations:

MAD = (2.9 + 0.1 + 1.1 + 0.1 + 0.1 + 1.1 + 0.1 + 0.1 + 0.9 + 1.1) / 10 = 0.8

Therefore, the MAD for this set of data is 0.8.
