thanks. that's the correct answer

This looks like a simple one, but I couldn't figure it out at all. Any ideas? Thanks. the average price per dozen eggs sold in a store for the last three months is: April $1.26 May $1.20 June $1.08 If 2/3 as many dozen were sold in April as in May, and twice as many were sold in June as in April, what was the average price per dozen of the eggs sold over the three-month period?

OA 36/65. Thanks guys!!...I saw where I was wrong.

you are correct...but why is wrong my solution? I'm missing a point somewhere... thanks

I might be wrong but, how about 42%? set up a matrix: college-no college; with job, no job plug in answer D and the results: college with job 42% college no job 36% no college with job 5% no college, no job 17% what do you think??

A class contains 8 boys and 7 girls. The teacher selects 3 of the children at random and without replacement. Calculate the probability that number of boys selected exceeds the number of girls selected. Here is my reasoning: we can select either 3 boys and 0 girls or 2boys and 1 girl. P=(8/15*7/14*6/13)+(8/15*7/14*7/13)= 728/2730 My answer is incorrect...what am I doing wrong?? thanks, www

Could someone pls send me the files ar soos12001@yahoo.ca? Thanks!

Thank you, wood. That really helped!

The answer is 2/5.

Hi I'm missing something here and I don't know what. Pls help! Two couples and one single person are seated at random in a row of five chairs. What is the probability that neither of the couples sits toghether in adjacent chairs? Here is my reasoning... P(N)= P of not sitting toghether P(T)= P of sitting toghether P(N)= 1-P(T) let the persons be x, x, y, y,z since the couples have to sit toghether, let be x,x = 1 person and y,y = 2 person so we have: 1, 2, z ways to sit 5 persons: 5!=120 ways to sit 1,2,z = 3!*2*2=24 then P(T)=24/120=1/5 and P(N)=1-1/5=4/5 What I'm doing wrong because this is not the right answer? Thanks!

I know I am wrong but can you explain me where? T starts at 4.30, J at 5.20. the difference is 50m=5/6of an hour Let x be the time when they read the same page 30*X=40(X-5/6) x=20/6=3h and 20min 3h20m+5:20=8:40 :shy:

352 Try plugging in Let's say r=2 V=1/8*2^3=1/64 when r is halved V=1/8*1^3=1/8 Now 1/64*X=1/8 x=8

Another way to solve 332 1500 bought for $600 means 0.40c/piece First day sold 1000 for 0.50c ( 0.25%*0.4c), meaning a profit of 10c/sold piece 10c*1000=$100.00 Secod day sold 500 for 0.45c ( 0.9% *0.5c), meaning a profit of 5c/sold piece 5c*500=$25.00 Total profit=$125.00

Just my opinion... A can't be the answer. It is said that it was an increase of 30 cents. 30c*40h=$12.00 . This can't be the minimum wage since $12.00 is just the increase. If we chhose A , that means that the employees worked for nothing? New salary= salary before the increase + the increase According to A $12.00= X + $12.00 X=0????

Here is my try: Since the letter mentioned a plague and there was only one outbreak of plague , the letter must be wriiten in that period. All the other answers are irrelevant to when Codex Berinensis was produced.

Thanks Erin! [??]

During the 1980s it became clear that soliciting private funds was far more efficient for environmentalists who sought financial aid than to appeal to state or federal agencies for support. A) that soliciting private funds was far more efficient for environmentalists who sought financial aid B) that, for environmentalists seeking financial aid, it was far more efficient to solicit private funds C) that for environmentalists seeking financial aid, private organizations were far more efficient to go to D) for environmentalists seeking financial aid, going to private organizations was far more efficient E) for environmentalists who sought financial aid private organizations were far more efficient I'd go with C. The right answer is B. Can you pls explain why? :shy:

Ok, I think there is something wrong because 8C3=7*8 I think of a way to solve this : for the 1st place= there are 8 ways to choose a participant for the second place= 7 ways ( you already have one participant for the 1st place) for the third place= 6 ways Total=8*7*6 If you think I am wrong, pls let me know Thanks!

nCk=n!/k!(n-k)! 10C2=10!/2!8! = 1*2*3*4*5*6*7*8*9*10/(1*2)(1*2*3*4*5*6*7*8)=45
