700, the correct estimate, is a lot closer to 645 than 500 is.
Exactly. Their rounding is atrocious: 354 down to 300 and 291 down to 200? Someday, products of this sort of math education will be designing the bridges we drive across, think about that.
Sorry Strina…little icon, big bird finger, no second chances!
wuwt? An Oahu stalker?
 Nevermind! this thing is slow as, grrrr. They updated Firefox and all hell is breaking loose, including flash crashes. My mistake.
There’s this thing called Safari…works each and every time, all the time… just sayin’… 😉
Arrrggghhhh. Grrrrr, nothing personal (i hate you) but this is really starting to urinate me off. Could give you a step by step of today but short version; security update>whole system scan, disk defrag (even tho it runs every Wed. a.m. after I log off), disk clean-up (including all thumbnails 80mb) and the kitchen sink and flash still crashes and this thing is slow as sorghum in the weather I have outside. Whew, I feel better. And that was the short version!
That’s why I don’t update Firefox when they tell me to, I always wait 2-3 weeks for them to get out the bugs. Same thing with Windows, but that is 2-3 months before I upate.
@MGAP, now I think about it got a quick Pshop tech Q for you when you’re out and about. My mouse is almost dead, kinda hard to draw a straight line when it ends up looking like an EKG. So…
Read some things about the higher end stuff but does it make that big a difference? Have you ever used one? If it’s like night and day I’ll go that way but if they’re not ‘magic’ we’ll just stick with the $25 wireless w/ the side clicker for airbrush.
Ghost, sorry I just noticed this post while digging about looking for something I had read. I think any mouse will give you the same results. If you want to go one better, you’re looking at the Wacom tablets, around 80 bucks and up. I have one of the cheaper ones that I never really used as much as I thought I would. I used it more with Elements 2.0 as there really were no selection tools in that version. When I got full blown PS, I never have used it any more. I reckon if I were to get into some intense detailed vector graphics project, it would help to learn to use one. Hope this helps.
Notice that they’re only checking to see if the answer is REASONABLE. Not CORRECT. We were taught ways of making sure answers were CORRECT when I was a kid. But that doesn’t matter any more.
That’s because this was designed by Liberals. They aren’t concerned if something is ‘right or wrong’, ‘true or false’ — these concepts don’t apply in Liberal-Land! The only thing that means anything in Liberal-Land is if it appears reasonable and feels good. With those two subjective criteria met, then the problem is solved.
Example: Is your 15 year old sister “HOT” to look at? Will you feel good jumping her bones? Problem solved!
Bunch of sick puppies, how did they ever survive the abortion clinic?
Hey flash, a little update. Daughter2 checked out your sites and basically said, “I thought you were just putting me in touch with some guy to ask questions, this guy’s a pro. I’m not going to clutter up his message board with my silly questions.”
She found a little used EOS 5D MarkII she’s picking up this week. Now the saving for lenses begins.
Ghost, I’m always open to questions, I love to teach what I know. Have her catch up with me on FB. I’m not hard to find.
Oh, and also thank her for the wonderful compliment.
Is that EOS a good choice you think? I know didly about high end cameras.
 she has a Rebel now but says it’s starting to limit her options.
The 5D MarkII is an excellent camera. It’s the one I wanted to get when I went high end, but could only afford a 60D at the time. She can use some of her lenses from the Rebel on the 5D, but not all of them will work well with the full frame sensor. Try them out, see what happens.
I would hate to think that my medication math would result in an answer so far off the mark. People would be getting killed with overdoses on a daily basis. And the common core clearly never learned to round properly.
You’re both wrong, the correct answer is eleventy!
Oooooohh…. I thought the answer was banana.
I’m not looking forward to the kids who took this form of garbage math making change for me at the local burger joint.
I am. I should have no trouble getting more back in change than I gave them, and a burger too.
LOL! I had a girl charge me $5 for a $10 scratch off ticket the other day! I gave her the other $5 and explained the mistake, but I should have shut up, it was a losing ticket.
They use the computerized register. Let the power go out and try to get them to count back your change.
Depends on how you do the estimation, but, yeah. Rounding rather than taking the floor (which is what the creator did) results in an answer with an error of +/- 100. At most, the rounded value will be 50 away from the actual value. With the floor function, the error is +/- 200. So, in the context of the writer’s version of rounding, any answer between 300 and 700 would be reasonable. With normal rounding, you get any answer between 600 and 800.
I honestly think this would be a good question if the writer actually understood rounding. Then again, I just got done researching Extended Kalman Filters, so the math part of my brain is in high gear right about now.
And when the hell did we turn on comment moderation?
“Ahh, jeez, they’re at it again!” — Archie Bunker
Just wow. I mean, doing estimates is a legit mathematical exercise, but yeah, this like all bass-ackwards! Wouldn’t you START with an estimate rather than the actual answer?!?
And for that matter, this is the kind of thing I do when I’m out shopping, to keep a rough running tally of what’s in the cart, but for these numbers I’d round the one to 350 and the other to 300, which gives a much better approximation than what this claptrap does! (which is more than 20% off.)
My comment is awaiting moderation?!?
Suddenly all comments were waiting for moderation. Don’t ask me what that’s about – something askew with Word Press I guess. I approved them all for now, but I know I’m not gonna spend the whole night approving comments, that’s for sure.
Hey JP, happy birthday (dammit! there, I said it so you don’t have to) But being close to your age (south, but close) this still has me lmao.
Any other seasoned folks, probably Mid-west (may be wrong) find this hilarious?
“no colors allowed”
It’s raaaaacist don’t ya know. As in “Biker”. Harleys. Beards and leather. Outlaws. Hells Angels. Road Hogs…
Had a blast last night, a little hung over I have to admit (adults went elsewhere after Chuck E Cheese), and yes, I read about the idiot black guy who thought “no colors” meant “no colored people.” Funny thing is, I didn’t realize there were any black people left in Dearbornistan – thought it was all Middle Eastern Muslim now. Maybe he was just passing through.
Happy Birthday a bit late. I was doing my final marathon work weekend in Daytona, and fell asleep before the computer finished booting up.
I don’t think you’re supposed to fall asleep while you’re running a marathon.
Listening to the guy speaking in the video, it all becomes very clear. He was educated in the local public school system.
Another perfect example opf taking offense when none was intended. Raaaacist indeed. On the part of the black person who assumed.
Did you know we had a spy @ the big Chuck E Cheese bash? Have a bootleg pic but may wait til his hangover as well as his sense of humor is better.
Hear tell he went through two rolls of quarters with the grands playing games before the ‘older folks’ moved on to the adult beverages establishment.
OK, that’s fine, I figured it was a goof with this thread, because I posted fine before and after these. Wondered at first what I might have done here!
Sensitive topic, since I still dunno what I might have done, but I just yesterday weaseled my way back onto Twitchy after being under the ban for a month or more, have to use Firefox with an IP spoofer, all my old Disqus IDs are contaminated now!
Related, this is something that’s just kinda stupid, but I generally kick off each computer day with the daily comics, starting my lineup at Arcamax (where there’s a good bunch of folks), and lately we’ve noticed that “Arcamax”, “moderator” or even just “mod” will flag a comment out for moderation!
Cool! SYFI net while I’m doing scut-paper-work; “Resident Evil: Extinction” followed by “Dawn of the Dead” @ 9. WooHoo!
Something that bothers me and I’m wondering if it’s just me. That first word, “Find.” Why do they use that word, like the answer is out there and you just need to look for it? Are they afraid if they say “calculate” the students will dissolve in fear and be traumatized for life?
Good God what are we doing to our children?
Maybe because with the way they’re teaching math now, it would be more likely that you will find the answer in an Easter Egg Hunt than by using Common Core math.
It’s the same math that the politicians use to balance the US budget
Bwaahahahahaha, they’re taking a page out of the Global Warming, Climate Change, Climate Chaos playbook; Change You Can Believe In! If it doesn’t fit, you must… change the name?
Makes me very happy that I don’t have any kids. If I were subjected to this bullshit, I would have to home school my kids.
FTA: “The standards are designed to ensure that students from all over the nation graduate with a baseline of math and language skills.”
Baseline? WHat do they mean by baseline? Is it 8th grade standards? College standards? 3rd grade standards?
If they were to make the baseline 6th grade standards from a bygone era, (http://www.washingtonpost.com/wp-srv/education/v/tests.pdf) I would agree with it, but you know they are only interested in dumbing down our kids so Big Brother won’t be questioned.
“I know all the math I need to know. You give me a ten, I punch the button with the picture of a cheeseburger on it, and it tells me how much to give you back.”
