Well, the answer quite simple ....there are 4! ways to arrange these numbers...and as 4! = 4*3*2*1 = 24
hence 24 is the correct answer....
u can also remember it by theorem of multiplication as.....in first place (I.e. first code can be any no. out of 4,5,2&7 ....so 4*.....
as first place is acquired by a certain no. that leaves three no. to fill third place and when third place I'd occupied it leaves 2 numbers to fill second place and lastly only one no. to fill the last place .....so it's result will be like 4*3*2*1.
I know this is pretty much confusing ....but still I tried my best....
if anything troubles u here feel free to ask me
We need slope of all lines ?
Slope of JK:-
Slope of KL:-
Slope of JL
Answer:
x = 0
Step-by-step explanation:
3 x -1 = -3 and 3 x -8x = -24x
-3 + 3( the opposite of the -3 given in the parentheses) = 0
-24x = 0
0/-24 (from -24x)= 0
x = 0
50 weeks is the age predicted by the best-fit line
Solution :
This is the two tailed test.
The null hypothesis and the alternate hypothesis is as :
Null hypothesis is 
Alternate hypothesis is 
Therefore, the critical value of z is :
Now the test statics is :
The test statics is 0.878
We see that it is a right tailed test.
= 0.3800
Thus , P-value > α
So we fail to reject the null hypothesis.
