Answer: The coefficient of the term with t^3 and q^14 in the expansion of (3t - q)^17 is 816 / 3.

Step-by-step explanation: The coefficient of the term with a certain power of t and a certain power of q in the expansion of a binomial raised to a power can be found using the binomial formula. The formula is given by:

Copy code

(a + b)^n = sum_{k=0}^n choose(n, k) * a^(n-k) * b^k

In this case, we have a = 3t, b = -q, and n = 17. We want to find the coefficient of the term with t^3 and q^14, which means we need to find the coefficient of the term with a^(n-k) = t^3 and b^k = q^14. Plugging these values into the formula, we get:

Copy code

(3t - q)^17 = sum_{k=0}^17 choose(17, k) * 3^(17-k) * (-1)^k * t^(17-k) * q^k

To find the coefficient of the term with t^3 and q^14, we need to find the value of choose(17, k) for k = 3. The binomial coefficient choose(n, k) is equal to the number of ways to choose k items from a set of n items. It can be calculated using the formula:

Copy code

choose(n, k) = n! / (k! * (n-k)!)

where n! is the factorial of n, which is the product of all positive integers less than or equal to n. For example, 5! = 5 * 4 * 3 * 2 * 1 = 120.

In our case, we have n = 17 and k = 3, so the coefficient we are looking for is:

Copy code

choose(17, 3) = 17! / (3! * (17-3)!) = 17 * 16 * 15 * 14 * 13 * 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / (3 * 2 * 1 * 14 * 13 * 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) = 17 * 16 / 3 = 816 / 3

Therefore, the coefficient of the term with t^3 and q^14 in the expansion of (3t - q)^17 is 816 / 3.

The options that represent binomial random variable  are;

A. Take a random sample of 30 tours and let L = the number of tours that result in a sale.

B. Take a random sample of 3 tours and let K = the number of tours that result in a sale.

There are 4 primary conditions for a random variable to be classified as binomial random variable and they are;

1. The number of observations n is fixed.

2. Each observation is independent.

3. Each observation represents one of two outcomes ("success" or "failure").

4. The probability of "success" p is the same for each outcome.

No, in this case, since 5% of home tours result in a sale, it therefore tells us that number of home tours is the independent variable while the amount of sales generated is the dependent variable.

From the above, we can access the given options and say that the last option is not a binomial random variable because the variable M is dependent and so does not satisfy one of the four conditions.

However, options A and B satisfy the 4 conditions and we say they are binomial random variables.

The equations that represent given problem is

P + S = 384 and 2.50P + 1.25S = 696.25.

What is an equation?

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Given that the cost of 1 slice pizza is $2.50.

The cost of 1 bottle can of soda is $1.25.

In total sell for a day is 384.

Assume that you sell P slice of pizza and S number of soda bottle.

Thus your total sell is P + S.

Therefore, P + S = 384.

The cost 1 slice pizza is $2.50

Then the cost P slice of pizza is $2.50P.

The unit rate of soda bottle is  $1.25.

Then the cost S bottles of soda is $1.25S.

Therefore the total sell for that day is 2.50P + 1.25S

50 feet each dimensions of the rectangular dog park producing the greatest enclosed area given 200 feet of fencing.

For an area to be the maximum of any rectangle the difference in length and breadth must be minimal. So, in such case, the length must be ceil (perimeter / 4) and the breadth will be floor(perimeter /4). Hence the maximum area of a rectangle with a given perimeter is equal to ceil(perimeter/4) * floor(perimeter/4).

Let X be the length and Y be the width of the rectangle. 200 ft of fencing material, so the maximum perimeter is 200 ft. Therefore first equation can be, 2X + 2Y = 200 => X + Y = 100 => Y = 100 — X

Equation of area of rectangle =>

A = X×Y => A = X(100–X) => A = 100X — X^2

Differentiate with respect to X on both sides

A' = 100 — 2X

Critical point => 100 — 2X = 0 => 2X = 100, X = 50

So maximum area is generated when the length and width of the fence are 50 feet each, which makes it a square. In mathematical terms, the square can be considered a rectangle.

The equation of the parabola is y = -1/4 x² + 3/2 x - 17/4. Where the vertex of the equation is at (3, -2) and the focus is at (3, -2 2/16) that opens downwards.

The equation of the parabola with vertex at (h, k) is

y = a(x - h)² + k

The focus of the parabola is represented by (h, k + 1/4 a).

It is given that, the vertex of the parabola is (h, k) = (3, -2)

And the focus of the parabola is (h, k + 1/4 a) = (3, -2 1/16)

From the focus point, we can calculate the value of 'a'.

(h, k + 1/4 a) = (3, -2 1/16)

⇒ k + 1/4 a = -2 1/16 = -33/16

⇒ -2 + 1/4 a = -33/16

⇒ 1/4 a = -33/16 + 2

⇒ 1/4 a = -1/16

⇒ a = -1/16 × 4

∴ a = -1/4

Since a is negative the parabola is downwards.

Now, the equation of the parabola is

y = a(x - h)² + k

On substituting the values, we get

y = -1/4(x - 3)² - 2

  = -1/4(x² - 6x + 9) - 2

  = -1/4 x² + 3/2 x -9/4 - 2

  = -1/4 x² + 3/2 x - 17/4

Therefore, the equation of the parabola is y = -1/4 x² + 3/2 x - 17/4.

Least time required to reach the point Q as per the distance and the speed rate is equal to 2 hours.

As given in the question,

Nearest point on the coast is 2 miles far away

rate of the row = 1mile per hour

Walk at the rate of 3 miles per hour

Let 'x' hours be the least time to reach point Q.

Time = distance / speed

Time taken to reach the point Q = [√ 1 + ( 3 - x)² ]/ 3

Time taken to reach the coast = (√ 4 + x² ) / 1

Total  time taken 't' = (√ 4 + x² ) / 1 + [√ 1 + ( 3 - x)² ]/ 3

To find least time dt/dx = 0

t  = (√ 4 + x² ) / 1 + [√ 1 + ( 3 - x)² ]/ 3

⇒dt/dx = [ x / √ 4 + x² ] + ( 3 - x) / √( 10 -6x + x² )

⇒x / √ 4 + x² = ( x - 3) / √( 10 -6x + x² )

Squaring both the side we get,

x² / (4 + x²) = ( x - 3)² / ( 10 -6x + x² )

⇒3x² -24x +36 =0

⇒ x² -8x + 12 = 0

The first number in the ordered pair tells us how far we are from the orgina (0,0) (the middle of the graph).  We are 3 units to the right.  The second number in the ordered pair tells us how far up or down from (0,0) we are.  You do not go up for down so that number should be zero.

The mean time of the entire operation is given by 31 seconds and standard deviation is approximately 4.47 seconds

mean time (μ₁) = 11 seconds

mean chassis time (μ₂) = 20 seconds

a)Total time taken = μ₁ + μ₂ = 11 +20 = 31  seconds

Now we will find the standard deviation:

standard deviation = √ (2²+4²) = √ 20 ≈ 4.47 seconds

b) The probability that the entire process will take less time:

Total time taken = 31 seconds

Less time taken will be 2 seconds for the entire time

P(T<30) = 30 - 31 / 4.47  = - 0.22

Now from the normal distribution table we get the p-value as :

p-value = 0.4129

Hence the required probability is 41.29 % .

The population or sample standard deviation and the standard error of a statistic are not the same thing, but they are related. The standard error of the sample mean is the standard deviation of the set of means computed by drawing an infinite number of repeated samples from the population and computing a mean for each sample.
