@satellite73 @amistre64 @.Sam. @Zarkon @beccaboo333 @mathmale The graph shows how the price of a stock has changed over the course of a year. Which is the best conjecture for the stock’s price in August? A. $9 B. $50 C. $35 D. $40

OpenStudy (compassionate):

There is no August

OpenStudy (anonymous):

I know...

OpenStudy (anonymous):

@AccessDenied @.Sam. CAN U HELP?

OpenStudy (anonymous):

Er...Hello?

OpenStudy (anonymous):

@Compassionate Do u know how to solve it?

OpenStudy (compassionate):

40.

Whats wrong Crazy

OpenStudy (anonymous):

@Compassionate I have 5 more. Can u help? 0_0

OpenStudy (anonymous):

Make that 6

The box-and-whisker plot shows the weights, in kilograms, of randomly selected packages in a mail truck. Which of the following conjectures does the plot support? A. The median weight of the packages in the truck is about 50 kilograms. B. Half of the packages in the truck weigh between 20 and 30 kilograms. C. There are at least 100 packages in the truck. D. About three-fourths of the packages in the truck weigh less than 50 kilograms.

@chaser71 Do u know it?

OpenStudy (compassionate):

Look at the point in the middle. It's the third one, right? It's the middle... therefore...

OpenStudy (anonymous):

It looks like B.

OpenStudy (compassionate):

Yup.

OpenStudy (anonymous):

I have 5 more now if that's ok.

OpenStudy (compassionate):

Go ahead...

OpenStudy (compassionate):

You have until 10:15... It is 10:00 my time.

Choose the counterexample that disproves the conjecture. For all real numbers n, 1 ÷ n > 0. A. n = 3 B. n = 1 C. n = 0.5 D. n = –0.5

OpenStudy (compassionate):

Well, if you divide 1 by -0.5, you get -2... which is less than 0..

OpenStudy (anonymous):

@Compassionate 2. If n is a prime number, then n^2 has a 1, 5, or 9 in the ones place. A. n = 3 B. n = 17 C. n = 31 D. n = 2 <------

OpenStudy (compassionate):

Yes.

OpenStudy (compassionate):

5 minutes.

OpenStudy (anonymous):

Which is a counterexample that disproves the conjecture? A student concludes that if x is a real number, then x ≥ x^3. A. x = 3 B. x = 1 C. x = 0 D. x = –1 IDK THIS ONE, I'M PRETTY SURE IT'S NOT A. @Compassionate

OpenStudy (compassionate):

I'm going out on a limb, as I don't know this type of math very well, but -1.
