q30 is from which chap?

[@salmamansour8637]

This was extremely helpful, thank you soo much!!

[@ScalarLearning]

I'm so glad the videos are helping you! Thank you so much for your support!

[@EverythingTechTime]

I got a 780 on this math test! Thats my best score so far. To put that in perspective I got a 580 on the psat

[@iqrayaqub8961]

which book did you study from? and whats the time period between your old and recent sat test?

[@EverythingTechTime]

@@iqrayaqub8961 college panda sat math. That along with khan academy and official practice tests. I took the psat last October but didn't start studying until June

[@iqrayaqub8961]

EverythingTechTime thank you so much:)

[@ScalarLearning]

Wow that's an amazing jump, congratulations!!

[@bruhrnav]

Can you please explain question 30? That one was kind of hard... I wonder what all CAN come on the August SAT looking at some of these concepts... I thankfully knew the Box and Whisker thing, but what to do with Q30?

[@gosnimm7624]

Hi, im not sure if i can help but this is how i solved. There are 3 triangles the whole triangle od the outside and the inside. Since the triangles are proportional, you can set up an equation. The largest triangle, the hypotenuse is 4+x and has a side of 5. And the inside of the triangle, which has a hypotenuse of 5 and a side of 4. Now you can create an equation 4+x/5=5/4. Cross multiply to get the x. 4(4+x)=25. 16+4x=25. 4x=9.x=2.25. The question is asking us the x coordinate of p. Watch out for this one, just because the x is 2.25 doesnt mean its 2.25. 4+2.25=6.25. So the answer is 6.25. Im sorry if this didnt help you.

Number 28 and 29...what is the plot called please??

Thank you very much! İt was really helpful.

You are welcome!

In 32:16 min you said 43 from where did you get it ?

[@ScalarLearning]

It's the exact center of 85 (42 to the left, 42 to the right)

[@error74583]

Can someone please explain to be Number 9: It says the in 1929 is when the sediment begun which caused the -1700 per year. So why does the test say we should begun to deduct from 1928 when in reality it was not reducing from 300k UNTIL 1929 due to the other river. Can someone please explain since I initially thought it was an error or mistake on behalf of the SAT test makers. thanks

[@Kn17tybn]

Can I get your opinion on College Panda Math practice tests? Are they close to the real thing?

[@ScalarLearning]

Yes, but harder. I'm a big fan of College Panda.

[@Mo.elshater]

Huzaifa could you please make a tutorial about dealing with like the table in question 29? it's pretty hard.

[@ScalarLearning]

I've got a video coming out this weekend that will address that.

im so confused on n10 lol doesn't that interval result in some values not fitting the solution

[@ScalarLearning]

Yes I believe so

[@husanr.4732]

can u do 2018 may us QAS next?

[@ScalarLearning]

I'll add to my list.

[@hassannazeer8245]

For question number 4, isn't option B sketchy considering the fact that they would be interviewing a "group" of 300 individuals in a survey which could lead to biased results as people's opinions might get influenced by others. Or am I inferring too much?

[@shaitoledano5867]

Can someone please help me with number 12? Why don't we consider the negative roots :(?

[@ScalarLearning]

They simply aren't considered on the SAT because they would make them non functions.

[@shaitoledano5867]

@@ScalarLearning I'll keep that in mind. No negative roots in general. Thanks! :)

[@fardinkhandaker3436]

I am still a bit confused at 18, Also, how did you know the triangles were proportional in question 30?

[@oz5191]

Great video helps alot!!!!

[@thepantry6448]

Don’t you think this test was comparatively harder?

[@ScalarLearning]

The calculator section was really hard, yes.

[@argogh6813]

can you plz explain 15 again

[@ScalarLearning]

I need a more specific question.

[@argogh6813]

@@ScalarLearning why it has to be less than 4?

[@gosnimm7624]

@@argogh6813 Hey, I don't know if this will help you, but I found the answer this way: Since there are 10 players and got a mean score of 4, it must be x/10=4. To solve x, you can cross multiply and get x=40, which is the total. If half of the players, which are 5 players, get a mean score of 5, the x would be 25 because x/5=5. To find the rest, you have to subtract the score from the total: 40-25=15. Since there are 5 players remained, it is simply just 15/5=3. The answer is less than 4, so it's A. Hope this helped you; sorry if it didn't.
