<h2>Answer:</h2>

<u> Angle C is 7 * 18 - 4 = 122 </u>

<u> Angle B is 18 + 4 = 22 </u>

<u> Angle D is 2 * 18 = 36</u>

<h2>Step-by-step explanation:</h2>

As we know that the sum of all angles of a triangle is 180

So adding all the angles we get

2x + x+4 + 7x-4 = 180

10x = 180

10x = 180

x = 18

In order to find each angle, put x = 18.  

 Angle C is 7 * 18 - 4 = 122

Angle B is 18 + 4 = 22

Angle D is 2 * 18 = 36

Answer:

B = 22

C = 122

D = 36

Step-by-step explanation:

The angles of a triangle add to 180. Take the measure of each angle add them together. Set them equal to 180.

2x + x + 4 + 7x - 4 = 180

10x = 180

x = 18

To find each angle, substitute x = 18.

Angle B is 18 + 4 = 22

Angle C is 7(18) - 4 = 122

Angle D is 2(18) = 36

A quarterback throws a football with a velocity of 41 mph and a direction of 168°. The wind on the field is 11 mph with a direct
Cerrena [4.2K]

The true speed and direction of the football thrown by the  quarterback is 30.185 mph and 9⁰ respectively.

<h3>Relative velocity of the football</h3>

The true speed and direction of the football is determined by applying the concept of relative velocity.

Vr/w = Vb - Vw

where;

  • Vr/w is the velocity of the football with respect to the wind
  • Vb is the velocity of the football
  • Vw is the velocity of the wind

Vr/w = 41 mph - 11 mph = 30 mph

The direction speed can be determined by sketching a triangle

Direction of the speed, θ = (360 - 339) - (180 - 168)

                                       θ = 21 - 12 = 9⁰

<h3>Resultant speed;</h3>

R² = 41² + 11² - 2(41 x 11 x cos9)

R² = 911.105

R = √911.105

R = 30.185 mph

Thus, the true speed and direction of the football thrown by the  quarterback is 30.185 mph and 9⁰ respectively.

M- Determine whether or not the procedure described below results in a binomial distribution. If it is not​ binomial, identify a
Igoryamba

Answer:

A. Yes, the result is a binomial probability distribution.

Step-by-step explanation:

The experiment above depicts a binomial probability distribution because the 4 required conditions are met :

1.) The distribution is independent as the possible outcome of each trial is the same.

2.) There are two possible categories and the result of each trial is one of two outcomes : Yes or No

3.) The number of observation is fixed at sample size of 5500

4.) The probability of success and failure of each trial is the same for all trials in the sample.

Hence, we can conclude that the experiment depicts a binomial probability distribution.
