Answer:

x = $\frac{7}{12}$

Step-by-step explanation:

Given

$\frac{x}{\frac{7}{8} }$ = $\frac{2}{3}$ ( cross- multiply )

3x = 2 × $\frac{7}{8}$ = $\frac{7}{4}$ ( divide both sides by 3 )

x = $\frac{7}{12}$

Answer: The number that goes in the green box is 7

Step-by-step explanation: The LHS of the equation can also be expressed as,

x/ (7/8) OR

x times (8/7)

That is, 8x/7

In other words, the equation now becomes;

8x/7 = 2/3

By cross multiplication we now have

8x(3) = 7(2)

24x = 14

Divide both sides of the equation by 24

x = 14/24

(Simplified further)

x = 7/12

Therefore the number that goes in the green box is 7.

Answer:

Step-by-step explanation:

Median: First write in ascending order. If number of data's is odd, median is the middle data.

If number of data's is even, then median = average of n/2th and (n+2)/2th term.

1) 1 , 3 , 5 , 5 , 6

Median = 5

2) 3,4,10,2,1

Ascending order: 1,2,3,4,10

Median = 3

3) 4, 5,7,11

Median = (5+7)/2 = 12/2 = 6

4) 1,1,2,6

Median = (1+2)/2 = 3/2 = 1.5

5) 2,2,3,3,,5,7

Median = 3+3/2 = 6/2 = 3

6)1,2,4,6,7,7

Median = (4+6)/2 = 10/2 = 5

7) 2,2,3,6,7,8

Median = (3+6)/2 = 9/2 = 4.5

8)1,2,3,14,17,18

Median = (3+14)/2 = 17/2 = 8.5

Mean= Sum of all the items÷ number of items

1)Mean = (1+2+3+2)÷4 = 8÷2 = 4

2)Mean=(4+3+2+4+2)÷5 = 15÷5 = 3

3)Mean = (5+4+6+1)÷4 = 16÷4 = 4

4)Mean = (2+5+1+4+7+5)÷6 = 24÷6 = 4

5)Mean =(10+11+9+12+8)÷5=50÷5 = 10

6)Mean = (1 + 2 + (-2)+1+(-2) )÷5 = -2÷5 = -0.4

7)Mean = (4+(-2)+3+(-3)+3)÷5 = 5÷5 = 1

8)Mean = (4+5.5+3+5.5)÷4=18÷4 = 4.5

A plane flies at 350 mph in the direction N 40° E with a wind blowing at 40 mph in the direction S 70° E. What is the plane’s dr

kozerog [31]

Answer:

The drift angle is approximately 7.65° towards the East from the plane's heading

Step-by-step explanation:

The speed of the plane = 350 mph

The direction in which the plane flies N 40° E = 50° counterclockwise from the eastern direction

The speed of the wind = 40 mph

The direction of the wind = S 70° E = 20° clockwise from the eastern direction

The component velocities of the plane are;

$R_{Plane}$ = (350 × cos 50)·i + (350 × sin 50)·j

$R_{Wind}$ = (40 + cos 20)·i - (40 × sin 40)·j

The resultant speed of the plane = $R_{Plane}$ + $R_{Wind}$ = 265.915·i +242.404·j

The direction the plane is heading = tan⁻¹(242.404/265.915) ≈ 42.35°

Therefore, the drift angle = Actual Angle - Direction of the plane = 50 - 42.35 ≈ 7.65° towards the East
