Some symbols are missing. I'm assuming you meant to put in a horseshoe symbol like so
If so, then the contrapositive of that would be
which is the final answer.
The tilde sign
means "not" so writing
means "not q" which is the complete opposite of q.
Answer:
x = 9
Step-by-step explanation:
The big triangle is similar to smaller one so we can use the side lengths' proportion to find x:
7/4 = (x-3)+8/8
7/4 = (x+5)/8 cross multiply expressions
56 = 4x + 20 subtract 20 from both sides
36 = 4x divide both sides by 4
9 = x
Answer:
-1/2
Step-by-step explanation:
the slope of a line that is perpendicular to a given equation of a line, is the negative reciprocal of the original slope
Answer:
69.5%
Step-by-step explanation:
A feature of the normal distribution is that this is completely determined by its mean and standard deviation, therefore, if two normal curves have the same mean and standard deviation we can be sure that they are the same normal curve. Then, the probability of getting a value of the normally distributed variable between 6 and 8 is 0.695. In practice we can say that if we get a large sample of observations of the variable, then, the percentage of all possible observations of the variable that lie between 6 and 8 is 100(0.695)% = 69.5%.
