An airplane is flying in a direction of 165° with an airspeed of 650 mph. The wind is blowing at 50 mph in a direction of N 30° E. What is the ground speed and direction of the plane?
A) ground speed: 658 mph; direction 108°
B) ground speed: 639 mph; direction 161°
C) ground speed: 686 mph; direction 108°
D) ground speed: 698 mph; direction 161°
Answer:
B) Ground speed: 639 mph; direction 161°
Step-by-step explanation:
165° = 75° South of East = S15°E, therefore;
The component of the speed of the airplane are;
650 × cos(75°) East or x-direction in vector form:[tex]$650 \times \cos \left(75^{\circ}\right) \mathrm{i}$[/tex]
650 × sin(75°) South or negative y-direction in vector form: [tex]$-650 \times \sin \left(75^{\circ}\right) \mathrm{j}$[/tex]
The speed of the airplane is [tex]$650 \times \cos \left(75^{\circ}\right) \mathrm{i}-650 \times \sin \left(75^{\circ}\right) \mathrm{j}$[/tex]
The speed of the wind in vector form is 25i + 25·√3 j
The combined speed of the airplane and the wind is found as follows;
Combined: [tex]$\left(650 \times \cos \left(75^{\circ}\right)+25\right)\left[\dot{i}+\left(25 \cdot \sqrt{3}-650 \times \sin \left(75^{\circ}\right)\right) \mathrm{j}\right.$[/tex], which gives;
The resultant speed of the airplane, [tex]$\left.R=\sqrt{(} 193.23^{2}+(-584.55)^{2}\right)=615.66$[/tex]
The resultant speed of the airplane, [tex]$\mathrm{R}=615.66 \mathrm{mph}$[/tex]
The direction =[tex]$\arctan ((-584.55) /(193.23))=-71.7^{\circ}$[/tex]
The bearing [tex]$=90^{\circ}+71.7^{\circ}=162^{\circ}$[/tex]
Therefore, the closest option is option B, ground speed: 639 mph; direction 161°

https://brainly.com/question/18868816We're planning to enclose a rectangular field with fencing, and we know that for whatever reason we want the field to be 50 feet square. We also know that the field's width should be 23 feet longer than the field's length. What are the field's dimensions?
Answer:
[tex]? \times \frac{?}{?} [/tex]
d
Answer:
2 by 25 feet.
Step-by-step explanation:
Let L and W be the length and the widht of the field
we want W = L + 23 and W x L = 50
So
(L + 23) x L = 50
[tex]L^2 + 23L = 50\\L^2+23L-50 =0\\(L+25)(L-2)=0\\L=-25 \text{ or } L = 2[/tex]
Since L must be positive then L =2 and W = 2 + 23 = 25.

MO bisects LMN, mLMN = 6x-28, mLMO = x+34. Find mNMO.
Answer:
D. 58°Step-by-step explanation:
MO is angle bisector of ∠LMN, so:
m∠LMN = 2*m∠LMOSubstitute with expressions:
6x - 28 = 2(x + 34)Solve for x:
6x - 28 = 2x + 686x - 2x = 68 + 284x = 96x = 24Find m∠NMO:
m∠NMO = m∠LMO = x + 34 = 24 + 34 = 58°Correct choice is D
If there are 100 students in your class and everybody flips a coin five times, how many people are likely to get five heads in a row?
This is with the assumption that every time you flip a coin, the chance that heads will end up on top is 1 in 2.
Will award brainiest, thank you!
If you flip a coin once, you have a 1/2 chance of getting heads. You will get either a head or tail.
Flipping a coin twice gives you a 1/4 chance of getting 2 heads since you will either get a 2 heads, 2 tails, a tail then head, or a head then tails.
From this we can see its pretty likely the pattern will continue if our chances of continually getting a head keeps halfing. So we can represent it as 1/2^n (half to the power of n) where n is the number of times we flip the coin.
So the odds of flipping a coin 5 times and getting 5 heads are 1/2 ^5 (half to the power of 5). Which gives us 1/32 or just over a 3% chance.
Here we have a probability problem.
We will find that the expected number of students that gets 5 heads in a row is 3.
First, we need to find the probability of getting 5 heads in a row.
We assume that the probability of getting heads in a flip is p = 1/2 = 0.5
Then for getting heads 5 times in a row, the joint probability will be the product of the individual probabilities, we get:
[tex]P = (0.5)*(0.5)*(0.5)*(0.5)*(0.5) = (0.5)^5 = 0.03125[/tex]
Now if we have N persons, such that all of them flip a coin 5 times, the expected number of people that will get 5 heads in a row will be equal to the total number of people times the probability of getting 5 heads in a row.
N*P
So if in the class there are 100 students, we have N = 100
The expected number of students that will get 5 heads in a row is:
[tex]100*P = 100*0.03125 = 3.125[/tex]
Because we can have a 0.125 of a student, we need to round this to the nearest whole number, which is 3.
So we should expect that 3 students will get 5 heads in a row.

Her ball will land near the hole approximately 48 times.
The histogram below shows the number of points scored by a high school basketball team over two seasons.
One player on the team wants to emphasize that his team generally scored a lot of points. Which measure of center should he report: the mean or the median?
a. He should report the mean.
b. He should report the median.
c. He could report either because they are equal.
d. The exact number of points per game are needed to decide.
To median should be reported in the to show th general measure of center since we have a skewed distribution.
The plot of the histogram Given is skewed to the right, hence it is positively skewed.
In a positively skewed distribution, the mean value of the distribution is always greater than the median. However, it does not give an accurate measure of center as much as the median does.
Therefore, if a player want to emphasize that his team generally scored a lot of points, then reporting the median would be best as it gives a better measure of center.
If the data was normally distributed, then the mean would be a better measure of center.

Use the Echelon Method
1. Solve
x + 3y = 7
3x + 4y = 11
Answer:
x = 1 y = 2
Step-by-step explanation:
x + 3y = 7
- Subtract x from both sides.
3y = -x + 7
- Divide both sides by 3 to isolate the variable.
y = -1/3x + 7/3
- Plug the value of y into the other equation.
3x + 4(-1/3x + 7/3) = 11
3x - 4/3x + 28/3 = 11
- Add like terms.
5/3x + 28/3 = 11
5/3x = 5/3
x = 1
- Plug the value of x into the equation.
x + 3y = 7
(1) + 3y = 7
3y = 6
y = 2
