Ok so on the first draw, 6/24 marbles are likely to be blue so there is 1/4 chance of obtaining blue originally. But, she puts it back and again it's 1/4 of obtaining the blue again. So 1/4 X1/4 = 1/16.
Answer:
About $118.70
Step-by-step explanation:
139 x .2 = 27.8
139 - 27.8 = 111.2
111.2 x .0675 = 7.5
111.2 + 7.5 = 118.7
118.7 = $118.70
Answer:
Step-by-step explanation:
Using the distance formula,

So the perimeter is 
Answer:
Step 1: It should be m∠m + m∠n + m∠o = 180° (sum of angles in a triangle)
Step-by-step explanation:
He made the mistake in Step 1: m∠m + m∠n + m∠p = 180°
It should be m∠m + m∠n + m∠o = 180°
Then only, he can equate it with m∠o + m∠p in step 3.
So, m∠p is the exterior angle and m∠m and m∠n are the two remote interior angles.
m∠o is the adjacent angle to m∠p. They form a linear pair.
Hence, the correct answer is Step 1.
