Question

Is this right @hero ?
Which is the hypothesis of this statement?
If a and b are negative, then a + b is negative.

A. If a and b are negative, then a + b is negative.
B. If a + b is negative, then a and b is negative.
C. a and b are negative. <---
D. a + b is negative.

Because D is the conclusion, and that's the only part left. I don't have a better explanation, I'm sorry, I can't really explain why I think that's the answer. :)

Answer 1

I think the answer is C

Answer 2

@hero @wolf1728

Answer 3

@CrazyCountryGirl, what do you mean by "D" is the conclusion? What represents the conclusion? Can you explain your reasoning here a bit more? I just want to make sure you know what you are talking about.

Answer 4

@JCMMusic, you can't "think" what an answer is. Either you know it or you don't know it. If you don't know, don't blurt.

Answer 5

@Hero They're saying that a and b are negative so the conclusion must be a + b is negative. I'm sorry I don't really know how to put it in to a sentence.

Answer 6

Actually I can think, based on what I think I come up with an answer. It's the same thing you are doing.

Answer 7

@JCMMusic, can you come up with a reasonable statement as to why you think C is the answer. @CrazyCountryGirl, you still haven't convinced me that you know what you are talking about.

Answer 8

@JCMMusic, there's a difference between knowing and thinking. Thinking equates to guessing which is essentially not knowing. Knowing is being able to express logical reasoning supported by established theorems and properties.

Answer 9

@hero Uh...How do u want me to put it. I just told you I don't know how o put it into a sentence. How do u want me to convince you? The question is split into two parts, conclusion and hypothesis. C, is the hypothesis. D is the conclusion.

Answer 10

That's better @CrazyCountryGirl

Answer 11

OMG! Really? I didn't even mean to do that. :)

Answer 12

I think C is the answer because it says If a and b are negative, this means they had to be discovered as negative before figuring out adding them together made a negative. Hence, C is the hypothesis.

Answer 13

Wow, you're right. I thought @CrazyCountryGirl posted the previous question again. My bad @JCMMusic

Answer 14

Well, in either case, I think @CrazyCountryGirl has it figured out now.

Answer 15

Yep it's no problem, just be careful who you offend there are some pretty mean people out there.

Answer 16

I apologize for getting on your case @JCMMusic, @CrazyCountryGirl tricked me this time.

Answer 17

Yes, C is the correct answer.

Answer 18

It's fine I forgive you

Answer 19

Which is a conditional statement for this sentence?
All birds can fly.

A. If an animal can fly, then it is a bird.
B. If an animal can’t fly, then it is a bird.
C. If an animal is a bird, then it can fly. <---
D. If an animal is not a bird, then it can fly.

C - It's just switched up, it's pretty much the same sentence

Answer 20

Hero I can't write you back you haven't fanned me.

Answer 21

@CrazyCountryGirl, correct. @JCMMusic, I'll take care of it.

Answer 22

I can't write u back either.

Answer 23

Yep Hero is right you are correct.

Answer 24

@Hero Can u explain to me how to do this one, it's probably easy but my brain is fried. :)

A candidate for city council wants to determine how much support she has among the voters in her district by conducting a survey.
Which sampling method will most likely result in a biased sample?

A. The candidate selects every fifth name on a list of registered voters in her district.

B. The candidate randomly selects 100 voters in each of the five wards in her district.

C. The candidate surveys the first 100 people who pass by her campaign headquarters.

D. The candidate uses a computer program to randomly generate names of voters in her district.

Answer 25

C

Answer 26

The first 100 people that pass by is not diverse enough, you need to have people from different times.

Answer 27

Er...Can someone explain to me why that's the answer? @hero @JCMMusic

Answer 28

I was just about to explain that three of the choices represent "random" selections, while with one of the choices, the candidate for city council could easily have called her supporters to pass by her headquarters to take the survey. That's how those in power manipulate results.

Answer 29

Sure, unbiased surveys need to be as random as possible in order otherwise people will think you are making the survey to your own benefit.

Answer 30

Oh... I get it. :)

Answer 31

@hero
Which is the conclusion of this statement?
If a and b are both negative then a • b = |a| • |b|.

A. If a and b are both negative, a • b = |a| • |b|.
B. a • b = |a| • |b| if a and b are both negative.
C. a and b are both negative.
D. a • b = |a| • |b|. <---

Again two parts, and the conclusion part is D because a and b are both negative. It says it inside the sentence. :) Right? 0_0

Answer 32

@Hero So you're telling these people that people who think, don't know?
