Step-by-step explanation:

The simplified expression is 2cos²(x) + sinx - 1 = 0

The expression we will be simplifying is

=> 1/sinx+cosx + 1/sinx-cosx = 2sinx/sin⁴x-cos⁴x.

To begin, let us look at the left-hand side of the expression. We can combine the two fractions using a common denominator, which gives us:

(1/sinx+cosx)(sinx-cosx)/(sinx+cosx)(sinx-cosx) + (1/sinx-cosx)(sinx+cosx)/(sinx-cosx)(sinx+cosx)

Simplifying this expression using the distributive property, we get:

(1 - cosx/sinx)/(sin²ˣ - cos²ˣ) + (1 + cosx/sinx)/(sin²ˣ - cos²ˣ)

Next, we can simplify each fraction separately. For the first fraction, we can use the identity sin²ˣ - cos²ˣ = sinx+cosx x sinx-cosx to obtain:

1 - cosx/sinx = (sinx+cosx - cosx)/sinx = sinx/sinx = 1

Similarly, for the second fraction, we can use the same identity to obtain:

1 + cosx/sinx = (sinx-cosx + cosx)/sinx = sinx/sinx = 1

Substituting these values back into the original expression, we get:

1 + 1 = 2sinx/(sin⁴x - cos⁴x)

Now, we can simplify the denominator using the identity sin²ˣ + cos²ˣ = 1 and the difference of squares formula:

sin⁴x - cos⁴x = (sin²ˣ)² - (cos²ˣ)² = (sin²ˣ + cos²ˣ)(sin²ˣ - cos²ˣ) = sin²ˣ - cos²ˣ

Substituting this back into the expression, we get:

2 = 2sinx/(sin²ˣ - cos²ˣ)

Finally, we can simplify the denominator using the identity sin²ˣ - cos²ˣ = -cos(2x):

2 = -2sinx/cos(2x)

Multiplying both sides by -cos(2x), we get:

-2cos(2x) = 2sinx

Dividing both sides by 2, we get:

-cos(2x) = sinx

Using the double-angle formula for cosine, we get:

-2cos²(x) + 1 = sinx

Simplifying this expression, we get:

2cos²(x) + sinx - 1 = 0

The probability that a bat does not consume any mosquitoes in a 30-second interval is 0.0067379 or 0.67%.

In this case, the average rate of mosquitoes consumed by a bat is 10 per minute.

To find the rate for a 30-second interval, calculate the rate for 1 minute and then adjust it for the 30-second interval:

Average rate for 1 minute = 10 mosquitoes

Rate for 30 seconds = \(\dfrac{10 \,mosquitoes}{1 \,minute} \times \dfrac{1}{2}\)

                                  = 5 mosquitoes

The Poisson distribution probability mass function is given by:

\(\[ P(X = k) = \dfrac{e^{-\lambda} \cdot \lambda^k}{k!} \]\)

Where:

\(\(\lambda\)\) is the average rate of events.

In this case, to find the probability that k = 0.

So, let's plug in the values:

\(\(\lambda = 5\)\)

\(\(k = 0\)\), back to the formula as

\(\[ P(X = 0) = \dfrac{e^{-5} \cdot 5^0}{0!} \]\)

Calculating the probability as

\(\[ P(X = 0) = e^{-5}\)

                \(= 0.0067379\)

Therefore, the probability is 0.0067379 or 0.67%.

x(0) = 0.25 in (initial displacement from equilibrium). x'(0) = 0 ft/s (initial velocity)

We can use Newton's second law to formulate the initial value problem that governs the motion of the mass. The equation is given by:

m*a = F_net

where m is the mass, a is the acceleration, and F_net is the net force acting on the mass.

The net force can be found as the sum of the spring force, the viscous resistance force, and the force due to gravity. Therefore, we have:

F_net = F_spring + F_viscous + F_gravity

where F_spring is the force exerted by the spring, F_viscous is the force due to the viscous resistance, and F_gravity is the force due to gravity.

The force exerted by the spring is given by Hooke's law:

F_spring = -k*x

where k is the spring constant and x is the displacement from the equilibrium position. Since the spring stretches 3 in under a weight of 4 lb, we can find k as:

k = F/x = 4/3 = 4/0.25 = 16 lb/in

Therefore, the force exerted by the spring is:

F_spring = -16*x

The force due to viscous resistance is proportional to the velocity of the mass and is given by:

F_viscous = -c*v

where c is the viscous damping coefficient and v is the velocity of the mass. Since the viscous resistance force is 6 lb when the velocity is 3 ft/s, we can find c as:

c = F_viscous/v = 6/3 = 2 lb·s/ft

Therefore, the force due to viscous resistance is:

F_viscous = -2*v

The force due to gravity is given by:

F_gravity = -m*g

where g is the acceleration due to gravity (32.2 ft/s^2).

Substituting these equations into the equation for net force, we get:

ma = -16x - 2v - mg

Since the displacement x and the velocity v are both functions of time t, we can rewrite this equation as a second-order ordinary differential equation in terms of x:

mx'' + 2cx' + kx = m*g

where x' and x'' denote the first and second derivatives of x with respect to t, respectively.

This is the initial value problem that governs the motion of the mass, subject to the initial conditions:

x(0) = 0.25 in (initial displacement from equilibrium)

x'(0) = 0 ft/s (initial velocity)

Answer:

Mean would be most affected

Step-by-step explanation:

The mean is defined as the average value . If the data has extreme values then the average value automatically changes.

The median is the value which divides the data in to two halves. It is not affected by the extreme values. The middle value remains the same.

The mode is the value which occurs repeatedly. An extreme value in a data does not affect the mode.

For example I have 5 chocolate bars of sizes 5,6,7,7,9  and another 5 chocolate bars of sizes  5,6,7,7,12

Mean for the two sizes will be 34/5= 6.8  and 37/5=7.4

The median and mode in both sets is 7

The least-square equation for the given (x,y) data pairs is: y = 0.9048x + 0.6190

To find the least-square equation for the given (x,y) data pairs, we can use the method of linear regression. The equation of a line is given by:

y = mx + b

where m is the slope of the line and b is the y-intercept. The values of m and b can be calculated using the following formulas:

m = (nΣ(xy) - ΣxΣy) / (nΣ(x^2) - (Σx)^2)

b = (Σy - mΣx) / n

where n is the number of data points.

Using the given data, we can calculate the values of Σx, Σy, Σxy, and Σ(x^2) as follows:

Σx = 2 + 1 + 5 = 8

Σy = 4 + 3 + 8 = 15

Σxy = (24) + (13) + (5*8) = 42

Σ(x^2) = (2^2) + (1^2) + (5^2) = 30

Substituting these values into the formulas for m and b, we get:

m = ((342) - (815)) / ((330) - (8^2)) ≈ 0.9048

b = (15 - (0.90488)) / 3 ≈ 0.6190

Therefore, the least-square equation for the given data is:

y = 0.9048x + 0.6190

Rounded to four digits after the decimal, the equation becomes:

y = 0.9048x + 0.6190

The probability that the two randomly selected residents prefer the same gas station is approximately 0.289 or 28.9%.

To find the probability that the two randomly selected residents prefer the same gas station, we need to consider all possible combinations of gas station preferences.

Let's denote the event that the first resident prefers gas station A as A1, the event that the first resident prefers gas station B as B1, and the event that the first resident prefers gas station C as C1. Similarly, let A2, B2, and C2 represent the events for the second resident.

We want to calculate the probability of the event (A1 and A2) or (B1 and B2) or (C1 and C2).

The probability that the first resident prefers gas station A is P(A1) = 0.29.

The probability that the first resident prefers gas station B is P(B1) = 0.28.

The probability that the first resident prefers gas station C is P(C1) = 0.43.

Since we are assuming random selection, the probability of the second resident preferring the same gas station as the first resident is the same for each gas station. Therefore, we have:

P(A2 | A1) = P(B2 | B1) = P(C2 | C1) = 0.29 for each combination.

To calculate the overall probability, we need to consider all possible combinations:

P((A1 and A2) or (B1 and B2) or (C1 and C2)) = P(A1) * P(A2 | A1) + P(B1) * P(B2 | B1) + P(C1) * P(C2 | C1)

P((A1 and A2) or (B1 and B2) or (C1 and C2)) = 0.29 * 0.29 + 0.28 * 0.29 + 0.43 * 0.29

P((A1 and A2) or (B1 and B2) or (C1 and C2)) = 0.0841 + 0.0812 + 0.1247

P((A1 and A2) or (B1 and B2) or (C1 and C2)) ≈ 0.289

Therefore, the probability that the two randomly selected residents prefer the same gas station is approximately 0.289 or 28.9%.
