A spinner is divided into sections of equal size, of which some are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 20%. The probability of the arrow landing on a section colored blue is 10%. What is the probability of the arrow landing on a section colored green?

Answers

The probability Would Be 1/5

Answer:

70%

What is given: 20% of one color, and 10% of another.

That gives us 30% of 100%.

Take away the smaller percentage from the limit, which would be 30 from 100.

You are left with 70%, which means that 20% is red, 10% is blue, and 70% is green.

i believe it’s 5 and 7

The two angles must be supplementary with angles 6 will be angle 5 and 7.

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

⇒ 4 lines intersect to form 16 angles.

And, The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 13, 14, 15, 16,

Here, two combinations of angles 5 and 7 are having a sum of 180 degrees with angle 6.

So, The supplementary angles to angle 6 are angle 5 and angle 7.

Thus, The two angles must be supplementary with angles 6 will be angle 5 and 7.

Answers

Answer:

Just as with "regular" numbers, square roots can be added together. But you might not be able to simplify the addition all the way down to one number. Just as "you can't add apples and oranges", so also you cannot combine "unlike" radical terms. In order to be able to combine radical terms together,

those terms have to have the same radical part.
