The bearing of a plane from the airport is 65.

Mathematics
1 answer:
Ulleksa [173]3 years ago
5 0

Answer:

The bearing of the airport from the plane is 245°

Step-by-step explanation:

The bearing of a point from a location is given by the angle in degrees of rotation from the Northern direction of the location to the direction of the location of the point

The given bearing of the plane from the airport = 65°

Therefore, the direction of the plane from the Northern direction of the airport = 65°

From the Northern direction of the plane, the bearing of the airport = 245°

Fine lowest common values for x and y variables of A[4x - 7y = 2] <br> B[3x - 3y = 6]
OLEGan [10]

3x -3y = 6

or, 3(x -y)= 6

or, x-y =6/3

or, x-y = 2

or, x=2+y........eqn(i)

4x - 7y = 2

substituting the value of x from eqn(i)

or, 4(2+y) -7y = 2

or, 8 + 4y -7y = 2

or, -3y = 2-8

or, y = -6/-3

■ y=2

so in eqn(i)

x= 2+y

x= 2+2

■x = 4

.) A population of values has a normal distribution with μ=27.5 and σ=71.5. You intend to draw a random sample of size n=180.
Paraphin [41]

Answer:  a) 27.5, b) 5.33.

Step-by-step explanation:

Since we have given that

\mu =27.5\\\\\sigma =71.5

and n = 180

We need to calculate the sample mean and sample standard deviation.

So, the mean of the distribution of sample means is

\mu = \mu_x=27.5

The standard deviation of the distribution of sample means is

s=\dfrac{\sigma}{\sqrt{n}}=\dfrac{71.5}{\sqrt{180}}=5.329=5.33

Hence, a) 27.5, b) 5.33.

Pietro is given a test question asking him to show that the sum of two odd integers is
Flura [38]

Answer:  second option Let (2a +1) be an odd number. Let (2b +1) be a different odd number. Because the sum of these two numbers, 2(a + b + 1), is a multiple of 2, it is an even number.

Transversal t cuts parallel lines a and b as shown in the diagram. Which equation is necessarily true? a) m&lt;1=m&lt;2 b)m&lt;4
lara31 [8.8K]
If the numbering of the angles is similar to this:
1 | 2
-----
3 | 4
5 | 6
----
7 | 8

Then none of the the choices are necessarily true.

The equations would have been:
1 = 4 = 5 = 8
2 = 3 = 6 = 7
3 + 5 = 4 + 6 = 180
