PLEASE HELP!!! 20 POINTS!!! Which of the following is equivalent to the statement below?

If 3x + 1 = 10, then x ≠ 2.
Select the best answer from the choices provided.

A. If x ≠ 2, then 3x + 1 = 10.
B. If 3x + 1 = 10, then x = 2.
C. If x = 2, then 3x + 1 = 10.
D. If x = 2, then 3x + 1 ≠ 10.

Answers

Answer: Choice DIf x = 2, then 3x+1 does not equal 10.

====================================================

Arguments in the form "if this, then that" are known as conditionals. The original conditional can be written in the form "If P, then Q". The P and Q are placeholders for statements. In this case, replace P with "3x+1 = 10" and replace Q with "x does not equal 2"

It turns out that the contrapositive is entirely identical to the original conditional. The contrapositive is in the form "If not Q, then not P". You swap P and Q, also you add "not"s to each to negate them both.

"P" means "3x+1 = 10", so "not P" means "3x+1 does not equal 10"

"Q" means "x does not equal 2", so "not Q" means "x = 2"

"If P, then Q" ----> "if 3x+1 = 10, then x does not equal 2"

"If not Q, then not P" ----> "if x = 2, then 3x+1 does not equal 10" is the proper contrapositive we want.

Hey, can someone please teach me this? I haven't been at school to learn it and I have a quiz later. Example:
The scores on the SAT form a normal distribution with a mean of 500 and a standard deviation of 100.

What is the minimum score necessary to be in the top 15% of the SAT scores?

Find the range of values that define the middle 80% of the distribution of SAT scores.

Answers

Answer:

604

Step-by-step explanation:

"Top 15%" corresponds to the rightmost area under the standard normal curve to the right of the mean.  That means 85% of the area under this curve will be to the left.  Which z-score corresponds to the area 0.85 to the left?

Using a calculator (invNorm), find this z-score:  invNorm(0.85) = 1.0346.

Which raw score corresponds to this z-score?

Recall the formula for the z-score:

       x - mean

z = ------------------

         std. dev.

Here we have:

       x - 500

z = ------------------ - 1.0364, or x - 500 = 103.64.  Then the minimum score

          100                necessary to be in the top 15% of the scores is

                                  found by adding 500 to both sides:

                                   x = 603.64

And thus for a time I was occupied by exploded systems, mingling, like an unadept, a thousand contradictory theories and floundering desperately in a very slough of multifarious knowledge, guided by an ardent imagination and childish reasoning, till an accident again changed the current of my ideas. When I was about fifteen years old we had retired to our house near Belrive, when we witnessed a most violent and terrible thunderstorm. It advanced from behind the mountains of Jura, and the thunder burst at once with frightful loudness from various quarters of the heavens. I remained, while the storm lasted, watching its progress with curiosity and delight. As I stood at the door, on a sudden I beheld a stream of fire issue from an old and beautiful oak which stood about twenty yards from our house; and so soon as the dazzling light vanished, the oak had disappeared, and nothing remained but a blasted stump. When we visited it the next morning, we found the tree shattered in a singular manner. It was not splintered by the shock, but entirely reduced to thin ribbons of wood. I never beheld anything so utterly destroyed. Before this I was not unacquainted with the more obvious laws of electricity. On this occasion a man of great research in natural philosophy was with us, and excited by this catastrophe, he entered on the explanation of a theory which he had formed on the subject of electricity and galvanism, which was at once new and astonishing to me. All that he said threw greatly into the shade Cornelius Agrippa, Albertus Magnus, and Paracelsus, the lords of my imagination; but by some fatality the overthrow of these men disinclined me to pursue my accustomed studies. It seemed to me as if nothing would or could ever be known. All that had so long engaged my attention suddenly grew despicable. By one of those caprices of the mind which we are perhaps most subject to in early youth, I at once gave up my former occupations, set down natural history and all its progeny as a deformed and abortive creation, and entertained the greatest disdain for a would-be science which could never even step within the threshold of real knowledge. In this mood of mind I betook myself to the mathematics and the branches of study appertaining to that science as being built upon secure foundations, and so worthy of my consideration. What is the effect of having Victor summarize the events of his childhood rather than telling them in detail? Readers can only guess at who Victor really is. Readers can see the events from more than one perspective. Readers cannot form an opinion without Victor's interpretation. Readers see little to suggest Victor is guilty of any crime.
