Answer:
C
Step-by-step explanation:
I'm pretty sure, good luck
The side of the triangle is 13 inches
Side of square. 6 inches
X= side of square
4x+15 =3(x+7)
4x+15=3x+21
x=6
6+7= 13
Perím square 6x4= 24
Perim triangle 13x3=39
39-24=15
The required probability is 0.171.
What is probability?
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
We can find required Probability as shown:
From 10 coins we choose 7 he guessed correct with probability of each 1/2. For three remaining coins he failed to predict the outcomes of the flip with the probability of 1/2 for each. Similarly for 8,9 or 10 successive trials. Let X denote number of successive trials




=0.171
Hence, the required probability is 0.171.

Given question is incomplete. This is complete question:
A man claims to have extrasensory perception. As a test, a fair coin is flipped 10 times and the man is asked to predict the outcome in advance. He gets 7 out of 10 correct. What is the probability that he would have done at least this well if he had no ESP?

I can't think of anything extra that I can add to this.
nickels / dimes = 21/13
This is as low as the ratio goes. There is no common factor.
