a plane travels n20 w at 360 mph and encounters a wind blowing due weat at 25 mph. What is the plane’s resulting velocity?

Answers

The magnitude of the resulting velocity: sqrt(312.3^2 + 123.5^2) = 337.1 mph. Therefore, the plane's resulting velocity is 337.1 mph towards the northwest.

To get the plane's resulting velocity, we need to use vector addition. The plane is traveling at a velocity of 360 mph towards the northwest (n20 w). The wind is blowing towards the east (due west + 180 degrees) at a velocity of 25 mph. We can break down these velocities into their x and y components.
The plane's velocity towards the northwest can be broken down into a velocity towards the west and a velocity towards the north. Using trigonometry, we can find that the plane's velocity towards the west is 360*cos(20) = 337.3 mph, and the plane's velocity towards the north is 360*sin(20) = 123.5 mph.
The wind's velocity towards the east can be broken down into a velocity towards the west and a velocity towards the north. Since the wind is blowing due west, its velocity towards the north is 0 mph, and its velocity towards the west is -25 mph.
To get the plane's resulting velocity, we need to add the x and y components of the plane's velocity and the wind's velocity. The resulting velocity towards the west is 337.3 - 25 = 312.3 mph, and the resulting velocity towards the north is 123.5 mph.
Using the Pythagorean theorem, we can get the magnitude of the resulting velocity: sqrt(312.3^2 + 123.5^2) = 337.1 mph. Therefore, the plane's resulting velocity is 337.1 mph towards the northwest.

A demographer working for the U.S. Census Bureau wants to compare salaries for urban vs. rural areas. The demographer gets a sample of psychologists who live in urban areas and a sample of psychologists who live in rural areas. From each, the demographer finds out his or her annual income. What statistical test should the demographer use to see if a difference exists in a psychologist's income as a function of residential status

Answers

To determine if a difference exists in a psychologist's income as a function of residential status (urban vs. rural), the demographer can use the Independent Samples t-test.

The Independent Samples t-test is appropriate when comparing the means of two independent groups. In this case, the demographer has two independent samples: one from psychologists in urban areas and another from psychologists in rural areas.

The test will assess whether there is a statistically significant difference between the mean incomes of psychologists in urban and rural areas. It takes into account the variability within each group and provides a p-value indicating the likelihood of obtaining the observed difference in means by chance.

By conducting an Independent Samples t-test, the demographer can determine if there is evidence to support the hypothesis that residential status has an effect on a psychologist's income.

Answers

Answer:

He can put 7 cars together in 245,157 ways.

Step-by-step explanation:

The order in which the cars are put together is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

\(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

23 distinct train cars. How many ways can he put 7 cars together?

Combinations of 7 from a set of 23. So

\(C_{23,7} = \frac{23!}{7!(23-7)!} = \frac{23!}{7!16!} = 245157\)

He can put 7 cars together in 245,157 ways.

Given, that A class has 484848 students, one group of 242424 students chooses to play volleyball.

Then the teacher divides the remaining students into as many groups of 555 as possible to shoot baskets.

After that, the remaining students (not on a volleyball or basketball team) climb the rock wall.

Now, we are asked that the students who climb the rock wall

So, from a class of 484848 students if One group of 242424 students is made to play volleyball then there will be 242424 students remaining.

Now, to divide 242424 students into groups of 555 students,

we need to divide 242424 by 555, then we get

242424/555 = 436.8

Mina is 5 years old.
Mina's sister is 3 more than 4 times older than Mina.
Mina's mother is 10 less than 3 times older than Mina's sister.
How old is Mina's mother?

Answers

Answer: 59 years old

Step-by-step explanation:

Given that Mina is 5 years old, we can substitute this value into the expressions for Mina's sister's age and Mina's mother's age.

First, Mina's sister is 4 times older than Mina, so she is 4 * 5 = 20 years old. And since her sister is 3 more than 4 times older than Mina, her sister is 20 + 3 = 23 years old.

Next, Mina's mother is 10 less than 3 times older than Mina's sister, so she is 3 * 23 - 10 = 59 years old.

Therefore, Mina's mother is 59 years old.

3. (3 pts) Find the general solution of the following homogeneous differential equations. 2xyy' + (x² - y²) = 0

Answers

The general solution of the given homogeneous differential equation is:y = ±x√(Cx² + 2)

The given differential equation is: 2xyy' + (x² - y²) = 0

We have to find the general solution of the given homogeneous differential equation. To solve the above differential equation, we will use the substitution method.

Put y = vx and y' = v + xv'

Differentiating both sides w.r.t x: y' = v + xv' ⇒ v' = (y' - v)/x

Differentiating again w.r.t x: y'' = v' + xv'' + v' ⇒ y'' = (y'' - 2y'v + v² + xv')/x

Substituting these values in the given differential equation:

2x(v)(v + xv') + (x² - v²x²) = 0

2v + 2x²v' + x - v² = 0

2x²v' + 2v/x - v³/x = -1/x

We can write the above differential equation as:

2x²dv/dx + 2v/x = v³/x - 1/x

Separating the variables and integrating both sides:

∫dx/x = ∫[v/(v² - 2)]dv/x

⇒ ln |x| + ln |v² - 2| + C

⇒ ln |x(v² - 2)| = ln |Cx|

⇒ v² - 2 = Cx² (where C is a constant)

⇒ v = ±√(Cx² + 2)

Putting the value of v in y = vx, we get:

y = x√(Cx² + 2) and y = -x√(Cx² + 2)

how many strings of length 14 over the alphabet {a, b, c, d} have exactly three a's or exactly three b's or both?

Answers

Answer:

We know that there are 5,569,500 strings of length 14 over the alphabet {a, b, c, d} that have exactly three a's or exactly three b's or both

Step-by-step explanation:

We can use the principle of inclusion-exclusion to count the number of strings of length 14 over the alphabet {a, b, c, d} that have exactly three a's or exactly three b's or both.

First, let's count the number of strings with exactly three a's. We can choose the positions for the three a's in ${14 \choose 3}$ ways, and for each choice, we can fill the remaining 11 positions with any of the three remaining letters (b, c, or d) in $3^{11}$ ways. Therefore, the number of strings with exactly three a's is ${14 \choose 3} \times 3^{11}$.

Similarly, the number of strings with exactly three b's is ${14 \choose 3} \times 3^{11}$.

To count the number of strings with both three a's and three b's, we can choose the positions for the three a's in ${14 \choose 3}$ ways, and choose the positions for the three b's among the remaining 11 positions in ${11 \choose 3}$ ways. Then, we can fill the remaining 8 positions with any of the two remaining letters (c or d) in $2^8$ ways. Therefore, the number of strings with both three a's and three b's is ${14 \choose 3} \times {11 \choose 3} \times 2^8$.

By the principle of inclusion-exclusion, the total number of strings with exactly three a's or exactly three b's or both is:

Find the equation of the line through point (3,−3) and parallel to y=3x−4. Use a forward slash (i.e. "/") for fractions (e.g. 1/2 for 12). Y=

Answers

Answer:

y =3x - 12

Step-by-step explanation:

I'm fairly certain this is the answer.

Consider the point (3,-3). In terms of variables this is written (x,y).

Remember that the equation for slope is y = mx + b.

In that equation, "b" is your y-intercept, and "m" is your slope.

If 2 lines are parallel, they have the same slope but different y-intercepts. So you can use the slope from the equation y=3x-4 to find the parallel line. You can also plug in the values 3 and -3 to solve for b, our y-intercept.

If we set up the equation, we have -3 = 3(3) + b.

Now solve for b.

-3 = 9 + b

Combine like terms, so that -12 = b, and you have your y-intercept.

To create the equation, take out the coordinate pair that the line passes through, and only have the SLOPE and the Y-INTERCEPT showing in the equation.

Therefore, y = 3x - 12

Answers

The probability of getting someone who is a man or non-drinker is 0.969 (rounded to 3 decimal places).

The table shows the drinking habits of a group of college students by sex. To find the probability of getting someone who is a man or non-drinker, we need to add up the number of men and non-drinkers and divide by the total number of students in the group.

The number of non-drinkers is the sum of the non-drinkers for men and women, which is:

Non-drinkers = 135 + 187 = 322

The number of men is given in the table as:

Men = 199

To find the probability of getting someone who is a man or non-drinker, we add the number of men and non-drinkers and then divide by the total number of students in the group, which is given as:

Total = 420

Therefore, the probability of getting someone who is a man or non-drinker is:

P(man or non-drinker) = (Non-drinkers + Men) / Total

= (322 + 199) / 420

= 0.969

So, the probability of getting someone who is a man or non-drinker is 0.969 (rounded to 3 decimal places).
