Answer:

1/16

Step-by-step explanation:

first we find the probability of picking a 2 and then a 5 , then we multiply the two probabilities

probability of picking a 2 on the first time is 1/4 as there is 1 2 and 4 total cards.

the probability of picking a 5 is also 1/4 as there is 1 5 and 4 total cards

so the probability of picking a 2 and then a 5 would be 1/4 * 1/4 = 1/16

y = kx is the formula for direct variation

8 = k*20

divide by 20

8/20 =k

divide by 4

2/5 =k

y = 2/5 x

formula: y = 2/5x

b) y=2/5x

y = 2/5 *7

y = 14/5

or as a mixed number 2 4/5

An airplane flying at an altitude of 2600 m is approaching an airport run away located 56 km away (from the airplane to the run

Brrunno [24]

Given :

An airplane flying at an altitude of 2600 m is approaching an airport run away located 56 km away.

To Find :

The airplane’s angle of decent.

Solution :

Height of plane, h = 2600 m.

Horizontal distance of airplane from vertices is, d = 56 km = 56000 m.

Let, angle of depression is Ф.

So,

$tan \ \phi = \dfrac{56000}{2600}\\\\tan \ \phi = 21.54\\\\\phi = 87.34^o$

Therefore, the angle of decent is 87.34°.

Hence, this is the required solution.
