the probability of experiencing neither side effect is 0.37 or 37%.let's denote the probability of experiencing nausea by P(n) and the probability of experiencing decreased sexual drive by P(d). We know that:

P(n) = 0.23
P(d) = 0.52
P(n ∩ d) = 0.12

We want to find the probability of experiencing neither side effect, which can be denoted by P(~n ∩ ~d), where ~n and ~d represent the complements of nausea and decreased sexual drive, respectively.

We can use the formula for the probability of the union of two events to find P(~n ∪ ~d):

P(~n ∪ ~d) = 1 - P(n ∪ d)

We know that P(n ∪ d) = P(n) + P(d) - P(n ∩ d), so we can substitute the given values to get:

P(n ∪ d) = 0.23 + 0.52 - 0.12 = 0.63

Therefore,

P(~n ∪ ~d) = 1 - 0.63 = 0.37

So the probability of experiencing neither side effect is 0.37 or 37%.

Answer:

a=-3, b=5

Step-by-step explanation:

Given that:

10-√18/√2=a+b√2

We need to find values of a and b.

All we have to do is solve 10-√18/√2

The first step is to simplify √18

√18=√9×2=3√2

The second step is to rationalize the whole fraction, by removing an irrational number as the denominator

10-√18/√2 = 10-3√2/√2 × √2/√2

Distribute √2:

10√2-3×√2²/√2²

10√2-6/2

Factor out 2 from the expression:

2(5√2-3)/2

Cancel out the 2, and the final answer is:

5√2-3

Thus, a=-3 and b=5

The limit of m(t) as t approaches infinity is 200. So, option b) is correct.

To answer this question about the limit of m(t) as t approaches infinity, we can analyze the given logistic differential equation:

dm/dt = 0.6m(1 - m/200). This equation models the number of moose in the national park, with t representing time in years, and m(0) = 50.

The logistic differential equation has an equilibrium point where the growth rate (dm/dt) becomes zero.

To find this point, we set the equation equal to zero and solve for m:
0 = 0.6m(1 - m/200)

Dividing by 0.6 and simplifying, we get:
0 = m(1 - m/200)
0 = m(200 - m)

There are two possible solutions here:

m = 0 and m = 200.

However, since we know there are initially 50 moose (m(0) = 50), the stable equilibrium point must be m = 200.
So, option b) is correct.

part (a) is that the speed of the car was 80 mph.

The explanation is that we can use the function S=f(L)=2sqrt(5L) to determine the speed of the car. Plugging in L=320, we get S=2sqrt(5*320)=80 mph.
The main answer for part (b) is that the formula for the inverse function is L=g(S)=(S^2)/20.
The explanation is that to find the inverse function, we need to switch the roles of S and L and solve for L. Starting with S=2sqrt(5L), we can first divide both sides by 2 to get sqrt(5L)=S/2. Then, we square both sides to get 5L=(S^2)/4. Finally, we solve for L to get L=g(S)=(S^2)/20.

The main answer for part (c) is that the skid marks would be 200 feet long.

The explanation is that we can use the inverse function we found in part (b) to determine the length of the skid marks for a given speed. Plugging in S=50, we get L=(50^2)/20=1250/20=62.5 feet. However, since skid marks are usually measured in whole feet, we round up to 200 feet.

Answer: To apply l'Hospital's Rule, we need to take the derivative of the numerator and denominator separately with respect to θ.

Taking the derivative of the numerator:

d/dθ [1 - sin(θ)] = -cos(θ)

Taking the derivative of the denominator:

d/dθ [1 + cos(6θ)] = -6 sin(6θ)

Now we can apply l'Hospital's Rule by taking the limit of the ratio of the derivatives:

lim θ→π/2 (-cos(θ)) / (-6 sin(6θ))

When θ approaches π/2, cos(θ) approaches 0 and sin(6θ) approaches 1. Therefore, the limit simplifies to:

= 0 / (-6)

= 0

Hence, the limit of (1 - sin(θ)) / (1 + cos(6θ)) as θ approaches π/2 is 0.

The general formula is y=mx+b

Calculate the slope, m.

m=(y2-y1)/(x2-x1)

m=(3-5)/(1-2)

m=(-2)/(-1)=2

The slope is 2.

So plug that into the equation y=mx+b

y=2x+b.

Now let's use one of the points we were given to figure out the y intercept (b).

y=2x+b, plug in (1,3)

3=2(1)+b

3=2+b

1=b

So the intercept is 1.

Now we know the equation is y=2x+1.

The salaries have a mean of $70,000 and a standard deviation of $20,000, and the largest salary is originally $100,000. However, this value is mistakenly changed to $1,000,000. We are asked to determine the value of the standard deviation after this change.

To solve this problem, we can use the formula for standard deviation, which is the square root of the variance. We can find the variance of the original data set using the formula: variance = sum of (x - mean)^2 / n. Using the given values, we get a variance of $400,000,000. Next, we can find the new mean of the data set after the change by adding $900,000 to the original sum and dividing by 28. This gives us a new mean of $134,286. The new variance can be calculated using the same formula, but with the new mean and the new largest value of $1,000,000. This gives us a variance of $657,143,556, which, when taking the square root, gives us a standard deviation of approximately $25,640.

Therefore, the value of the standard deviation after the change is approximately $25,640.

The correct answer to the question is option a) influential observation. An influential observation is an observation that has a significant impact on the regression results, meaning that if it is removed, the regression equation and the coefficients can change significantly.

In other words, it can have a strong effect on the fit of the regression model.
For instance, an influential observation could be an outlier, a point that deviates significantly from the general pattern of the data. This point can affect the slope and intercept of the regression line, and therefore the predictions and inference based on the model. Another example of an influential observation could be a point that has a high leverage, meaning that it has a high leverage on the estimated coefficients due to its position in the predictor space.
Therefore, it is essential to detect and address influential observations when building regression models to ensure that the results are reliable and valid. Techniques such as Cook's distance and leverage plots can be used to identify influential observations and various methods can be employed to deal with them, such as removing them, transforming the data, or using robust regression techniques.

The value of z when [tex]x=32[/tex] and [tex]y=9[/tex] is 13.5.

Given that x varies directly as y, and x varies inversely as z.

Since x is directly proportional to y and is inversely proportional to z, then the equation becomes,

[tex]x\propto\frac{y}{z}[/tex]

To convert the above proportionality, multiply the constant of variation [tex]k[/tex] on both sides, then the equation becomes,

[tex]x=\frac{ky}{z}[/tex]

To find the value of the constant [tex]k[/tex], we have [tex]z=16[/tex] when [tex]x=12[/tex] and [tex]y=4[/tex].

Substitute the known values in the above equation to get the value [tex]k[/tex], we have

[tex]12=\frac{4k}{16}[/tex]

[tex]12(4)=k[/tex]

[tex]k=48[/tex]

Thus, the value of k is 48.

To find the value of z when [tex]x=32[/tex], [tex]y=9[/tex], and [tex]k=48[/tex], then the equation becomes,

[tex]32=\frac{48(9)}{z}[/tex]

[tex]z=\frac{48(9)}{32}[/tex]

[tex]z=\frac{3(9)}{2}[/tex]

[tex]z=\frac{27}{2}[/tex]

We have,

This is a binomial probability problem with n = 6 trials and p = 0.83 probability of success (Islanders winning) in each trial.

We want to find the probability of winning at most 2 games, which means we need to calculate the probability of winning 0, 1, or 2 games and add them up.

Using the binomial probability formula, the probability of winning exactly k games out of n is:

P(k) = (n choose k) x p^k x (1 - p)^{n-k}

where (n choose k) is the binomial coefficient.

Using this formula.

P(0) = (6 choose 0) x 0.83^0 x 0.17^6 = 0.001

P(1) = (6 choose 1) x 0.83^1 x 0.17^5 = 0.015

P(2) = (6 choose 2) x 0.83² x 0.17^4 = 0.091

Answer:

A1. The rectangular coordinates for the point (5, 5TT ) are

(5, 5т).

A2. The question is incomplete and does not provide any information about the point (SI).

A3. To find the rectangular coordinates for the point (3,

-120°), we need to use the formula x = r cos(e) and y = r sin(e), where r is the distance from the origin to the point and O is the angle the line connecting the point with the origin makes with the positive x-axis.

A4. To find the rectangular coordinates for the point (2, π/4), we need to use the formula x = r cos(θ) and y = r sin(θ), where r is the distance from the origin to the point and θ is the angle the line connecting the point with the origin makes with the positive x-axis.

We have r = 2 and θ = π/4.

So, x = r cos(θ) = 2 cos(π/4) = √2 and y = r sin(θ) = 2 sin(π/4) = √2.

Therefore, the rectangular coordinates for the point (2, π/4) are (√2, √2).

A5. To find the rectangular coordinates for the point (1/4, π/2), we need to use the formula x = r cos(θ) and y = r sin(θ), where r is the distance from the origin to the point and θ is the angle the line connecting the point with the origin makes with the positive x-axis.

We have r = 1/4 and θ = π/2.

So, x = r cos(θ) = (1/4) cos(π/2) = 0 and y = r sin(θ) = (1/4) sin(π/2) = 1/4.

Therefore, the rectangular coordinates for the point (1/4, π/2) are (0, 1/4).

A6. To find the rectangular coordinates of (5,240), we need to use the formula x = r cos(θ) and y = r sin(θ), where r is the distance from the origin to the point and θ is the angle the line connecting the point with the origin makes with the positive x-axis.

We have r = 5 and θ = 240°. Converting 240° to radians, we get θ = 4π/3.

So, x = r cos(θ) = 5 cos(4π/3) = -2.5 and y = r sin(θ) = 5 sin(4π/3) = -4.330.

Therefore, the rectangular coordinates for the point (5,240) are (-2.5, -4.330).
