<h2>Answer :-</h2>

To draw a 50 degree angle with a protactor, proceed as follows :

  • Draw a straight line (i.e. an arm of the angle).

  • Place a dot at one end of the arm. This dot represents the vertex of the angle.

  • Place the centre of the protractor at the vertex dot and the baseline of the protractor along the arm of the angle.

  • Find 50 degree angle on the scale and then mark a small dot at the edge of the protractor.

  • Join the small dot to the vertex with a ruler to form the second arm of the angle.

  • Label the angle with capital letters.

Remember that 50 degree angle cannot be constructed using compass.

Students pass a test it they score 50% or more. the marks of a large number of students were sampled and the mean and standard d
Schach [20]
So we are given that the mean is 42% and the sd (standard deviation) is 8%
Assuming our data is normal we can use the 68-95-99 rule

So one thing you should realize is that 42% + 8% is 50% which is passing. That is one standard deviation higher. So we use:
 
100 - 68 - 13.5 - 2.35 - 0.15  = 16. That means 16% of students passed the test. Which is terrible. They probably need to hit the books more.

Anyways if you have any question feel free to message me!
Hopes this helps!

Solution q-2r=4<br> q+r=37
GenaCL600 [577]
Q-2r=4, therefore: q=4+2r.

Plug the value of q into q+r=37, so you get:

4+2r+r=37

3r=37-4=33

3r=33

Therefore: r=11.

q-2r=4, but r=11, so:

q-2(11)=4

q-22=4

Therefore q=26.

Check if the answer is correct using second equation:

q=4+2r=4+2(11)=4+22=26.

So: q=26 and r=11.
