Calculusf(x):
.i know that...but you as mr calculus said integral 7^u du/cosx it's not possible to take cosx out just as if it's a constant.hadn't been it's ln2 or 7 or any constant...it can...but this one can not be done like that...THOUGH...i don't know the question but if someone gets it i will know

Mr Calculus: plz guyz need ur help:::Convert 1111.100110 base 2 to base
12 and 123.X4 base 12 to base 2 without converting first to base 10

Mr Calculus: I really need ur help hear guys.

estilo: I greet all the maths gurus in d house ooooo. Please have come again I want you guyz to assist me to solve some statistics questins.am a Mass comm student and I dnt knw anytin abt calcultn(olodo gurl)pls help ur sis oooo.

Q1(A) ND2 class has 20 boys and 16girls, three students are selected frm the class at random one after the other. Find the probability that:
(1) The first two are boys and the third is girl
(11) The first and third are boys while the second is a girl
(111) The first and third are of the same sex while the second is of opposite sex.
(B)Every saturday a fisherman goes to the river,the sea and a lake to catch fishes with probabilities 1/4,1/2,and 1/4 respectively. If he goes to the sea,there is an 80% chance of catching fish,the corresponding figures for the river and the lakes are 40% and 60% respectively. (1) find the probability that he catches fish on a given saturday
(11) If on a particular Saturday he comes home without catching anything,where is it most likely he has been?
(111) His friend who is also a fisherman chooses any of the three locations with equal probabilities. Find the probability that the two fishermen will meet atleast once in three weekends (any assumption made should be clearly stated).



Q2(A) fit a regression Y= a+bx by the method of least square to the following sample information

Income '000:-41,65,50,57,96,94,110,30,79,65
Consumption/expenditure '000:-44,60,39,51,80,68,84,34,55,48
Find the level of income if consumption expenditure is 90.

(B)frm the two sets of numbers below which one is more widely dispersed.
A: 2,3,1,4,5,6,7,25,9,8
B: 32,45,40,38,47,50,43,36,44,35

ladokuntlad: pls help me find d value of x if x^2=4x. show workings oooo. hint x=4

papindinho: pls maths gurus help with this o.
The speed of 30km per min expressed in cm per sec = ?
Note= km means kilometre min means minute, cm =centimetre and sec=second

Mr Calculus: Plz guruz help out

BRAINEE123: Plz pals , solve this for me: If a body moves with a final velocity of 30km/hr and accelerates at 12km/hr^2 in 2hrs. What is the distance covered in 2.5hrs?

labodinho: Plz help me out.Hw do i solve logs with diff base like this No 1 Log9 base 3-Log3 base 27+ Log9 base sqaure root3.........No 2.Solve the equatn LogX base 2-Log(X-1) base 2=2.........This one is on Inequalities.No 3. (2x-1)(x+4) divided by x-5 both numerator n denominator Greater than(sign) 0 ....Tanx.

I couldnt type it but I hope the picture of my workbook is clear enough...

johnpaul1101: goodday richiez and all respectable mathematicians, plz i urgently need help with this:
If log x=bar 2.3675 and log y=0.9750, find x+y.
Thanks

labodinho: Oh,tanx.can't really see them clearly.Can u mail me on labodihoo@gmail.com or exercise patient by writing it.Plz,jst @ yur conveniency....

echibuzor:

Alrite man.. I ll type it on Word and attach it to the mail I am gonna send gonna send to u..

labodinho: Tanx bro.

Mr Calculus:
x=antilog of bar 2.3675
y=antilog of 0.9750..
anytin u get add it together

labodinho: Plz help me out.Hw do i solve logs with diff base like this No 1 Log9 base 3-Log3 base 27+ Log9 base sqaure root3.........No 2.Solve the equatn LogX base 2-Log(X-1) base 2=2.........This one is on Inequalities.No 3. (2x-1)(x+4) divided by x-5 both numerator n denominator Greater than(sign) 0 ....Tanx.

oladoya: here comes the answer... (1) log9-log3+log9 since they are in diff base just represent it with letter so we have A-B-C so lets solve A... Log9base3=a, then let the base have a as its power then we have 9=3^a, 3^2=3^a equate the base we have a=2.... Then lets take B... Log3base27=b, 3=27^b, 3^1=3^3b equ base, we have b=1/3.... Now C..... Log9basert3=c, 9= 3^c/2 we have 3^2=3^c/3 equ base we have 2=c/2 cross mult. We c=4 then remenber A-B+C = 2-1/3+4=17/3.... 2nd question (logx)base2-(logx-1)base2=2... According to the rule take a log(x/(x-1))=2, x/(x-1)=2^2, x/(x-1)=4 cross multiply you have x=4x-4, x-4x=4, -3x=-4, x=4/3...... No3 solving it quadratically we have x>1/2 or x>-4

rashywire: Log(x sq + 7x - 2) base 2 equal to Log(x sq + 3x -6) base 2 + Log8 base 4
