Velocity of jet in still air is 647 miles per hour and velocity of wind is 70 miles per hour.

Given,

Jet's velocity against wind 1731 / 3 = 577  mile per hour

flying with wind it   2151 / 3 = 717 miles per hour.

Let the velocity of jet in still air be x miles per hour and velocity of wind be y miles per hour.

As such its velocity against wind is x−y and with wind is x+y and therefore

x−y=577;

x+y=717

Adding the two

2x = 1294

x = 647

y= 717 − 647

y = 70

Hence velocity of jet in still air is 647 miles per hour and velocity of wind is 70 miles per hour.

The given problem involves finding the values of SST, SSR, and SSE, as well as the coefficient of determination and the sample correlation coefficient.  In this case, SST = 1936, SSR = 1504, SSE = 432, The coefficient of determination= 0.776, sample correlation coefficient= 0.88

The sum of squares total (SST) represents the total variability in the response variable, y. This is calculated as the sum of the squared differences between each y value and the mean of all y values. In this case, SST = 1936.

The sum of squares regression (SSR) represents the variability in y that is explained by the regression equation. This is calculated as the sum of the squared differences between the predicted y values from the regression equation and the mean of all y values. In this case, SSR = 1504.

The sum of squares error (SSE) represents the unexplained variability in y. This is calculated as the sum of the squared differences between each observed y value and the predicted y value from the regression equation. In this case, SSE = 432.

The coefficient of determination, denoted as R-squared, measures the proportion of the total variability in y that is explained by the regression equation. In this case, R-squared = SSR/SST = 1504/1936 = 0.776. This means that the regression equation explains 77.6% of the variability in y.

The sample correlation coefficient (r) measures the strength and direction of the linear relationship between x and y. It is calculated as the square root of R-squared. In this case, r = sqrt(R-squared) = sqrt(0.776) = 0.88 (to 2 decimal places).

In conclusion, the regression equation has a relatively good fit with the data as indicated by the high R-squared value of 0.776.

Jake will need to pay $1000, the property damage insurance will cover  $4,400 and the collision insurance will cover $1980.

A property damage insurance is a type of insurance that covers the damage you cause to someone else property. In a car accident, this covers the damages done to other cars or properties but not to your car.

Collision insurance covers the damages to your car when there is a collision. Moreover, the insurance is deductible if you need to pay a specific amount before you are covered by the insurance. For example, Jake's insurance will only cover him if the damages are worth more than $1000.

The property damage insurance is likely to cover $4.400 in damages that include the damage to the sign and another car ($2000 + $2400 = $4400).

Jake has a total of $2980 accounting for the damages in his car and the insurance will only cover the damages after $1000. This means they will cover $1980 ($2980 - $1000 = $1980).

Jake will need to pay $1000 because of the $100 deductible collision insurance.

Step-by-step explanation:

— 2-2/2-(-1) = 0/3 = 0. So the rate of change for f(x) =X2-X over the interval [-1,2] is 0.

a. Joint PMF: (0,0)=\((1-p)^2\), (0,1)=p(1-p), (1,0)=p(1-p), (1,1)=\(p^2\).

b. Marginal PMF: p_X(0)=1-p, p_X(1)=p(2-p), p_Y(0)=(1-p)(2-p), p_Y(1)=p(2-p).

c. Conditional PMF: p_X|Y(0|0)=(1-p)/(2-p), p_X|Y(1|0)=p/(2-p), p_X|Y(0|1)=p/(2-p), p_X|Y(1|1)=p/(2-p).

a. The joint PMF p_X,Y(x,y) can be gotten by thinking about all potential results of flipping a one-sided coin two times: (0,0), (0,1), (1,0), and (1,1). Let X be the limit of the two numbers, and Y be the base of the two numbers. Then, at that point, we have:

p_X,Y(0,0) = P(Tail, Tail) = \((1-p)^2\)

p_X,Y(0,1) = P(Tail, Head) = p(1-p)

p_X,Y(1,0) = P(Head, Tail) = p(1-p)

p_X,Y(1,1) = P(Head, Head) = \(p^2\)

b. To acquire the minimal PMFs p_X(x) and p_Y(y), we aggregate the joint PMF over the relating factors, i.e.:

p_X(0) = p_X,Y(0,0) + p_X,Y(0,1) = \((1-p)^2\) + p(1-p) = 1 - p

p_X(1) = p_X,Y(1,0) + p_X,Y(1,1) = 2p(1-p) + \(p^2\) = p(2-p)

p_Y(0) = p_X,Y(0,0) + p_X,Y(1,0) = \((1-p)^2\) + p(1-p) = (1-p)(2-p)

p_Y(1) = p_X,Y(0,1) + p_X,Y(1,1) = 2p(1-p) + \(p^2\) = p(2-p)

c. To find the restrictive PMF p_X|Y(x|y), we utilize the recipe:

p_X|Y(x|y) = p_X,Y(x,y)/p_Y(y)

For y = 0, we have:

p_X|Y(0|0) = p_X,Y(0,0)/p_Y(0) = \((1-p)^2\)/(1-p)(2-p) = (1-p)/(2-p)

p_X|Y(1|0) = p_X,Y(1,0)/p_Y(0) = p(1-p)/(1-p)(2-p) = p/(2-p)

For y = 1, we have:

p_X|Y(0|1) = p_X,Y(0,1)/p_Y(1) = p(1-p)/(1-p)(2-p) = p/(2-p)

p_X|Y(1|1) = p_X,Y(1,1)/p_Y(1) = \(p^2\)/(p(2-p)) = p/(2-p)

The restrictive PMFs show that if Y = 0, the likelihood of X = 1 is higher than X = 0, and if Y = 1, the likelihood of X = 0 is higher than X = 1. This can likewise be seen from the peripheral PMFs.

Answer: it’s C 175 - 0.23(175)

Step-by-step explanation:

Answer:

\(\displaystyle \large{y=\frac{18+4h}{5} }\\\)

Alternatively, you can use \(\displaystyle \large{y=\frac{18}{5}+\frac{4h}{5} }\\\) as an answer.

Step-by-step explanation:

To make y as the subject of equation, we have to find a way to isolate y-variable.

First, add 4h both sides of equation which we obtain:

\(\displaystyle \large{5y-4h+4h=18+4h} \\\displaystyle \large{5y=18+4h}\)

Next, we divide both sides by 5 so we can finally have y-isolated equation and thus it becomes the new subject of equation.

\(\displaystyle \large{\frac{5y}{5} =\frac{18+4h}{5} }\\\displaystyle \large{y=\frac{18+4h}{5} }\)

Thus the answer is y = (18+4h)/5

Alternatively for solution, you can separate the fraction which we obtain a valid alternative solution.

\(\displaystyle \large{y =\frac{18}{5} +\frac{4h}{5} }\\\)

Either one of these solutions work.

A plane flying just above the equator around the world 3 1/2 times would cover a distance of 4.375 x 10⁴ miles.

If an airplane travels around the world just above the equator once, it covers a distance of 1.25 x 10⁴ miles. To find how many miles it would cover if it flew around the world 3 1/2 times, we need to multiply this distance by 3.5:

1.25 x 10⁴ miles x 3.5 = 4.375 x 10⁴ miles

To understand this calculation, we need to know that 3 1/2 times means 3.5 times. So, we multiply the distance covered in one round of the world by 3.5 to find the total distance covered in 3 1/2 times around the world.

We use standard form to express the answer in a more compact and convenient way, where 4.375 x 10⁴ represents the number 43,750 in scientific notation.

Step-by-step explanation: To solve this inequality, we can first isolate the absolute value term on one side of the inequality by subtracting |n-2| from both sides of the inequality. This gives us the inequality -3 + |n-2| > 2. Then, we need to consider two cases: when |n-2| is positive and when |n-2| is negative.

If |n-2| is positive, then we can drop the absolute value bars and rewrite the inequality as -3 + (n-2) > 2. Solving this inequality, we find that n > 7.

If |n-2| is negative, then we must reverse the direction of the inequality because subtracting a negative number is the same as adding a positive number. This gives us the inequality -3 - (n-2) > 2. Solving this inequality, we find that n < -1.

Therefore, the solution to the inequality is the set of all numbers that are greater than 7 or less than -1, which is the interval (-1, 7).

Linear expression has only first-order linear terms. The only expression from all the given expressions that is linear is 9x − 2.

A linear expression is an expression that can be put in the form of y=mx+c,

therefore, it has only one variable and is of the first order.

As we have discussed the linear expression, therefore, if the equation can be put in the form of y=mx+c then that expression will be a linear expression.

A.) 9x − 2

As the equation is of the first order and can be arranged as,

0 = 9x + (-2)
