Answer: e. 0.3849
Step-by-step explanation:
We know that the mean lies exactly at the middle of the normal curve .
The z-score of the mean value is 0.
Also According to the standard normal probability table, the probability value of z=0 is P(z<0)=0.5.
And the probability value of z=-1.20 is P(z<-1.2) =0.1150697.
Now, the area under the normal curve between the mean and a score for which z= - 1.20 is given by :-
Hence, the area under the normal curve between the mean and a score for which z= - 1.20 is 0.3849 .
In an algebraic expression, a coefficient is always multiplied, whether it be to another number or a variable.
Final answer: C
Answer:
7/13
Step-by-step explanation:
Let's call x= numerator
We know that :
Denominator= x+6
And
(numerator +2)/(denominator +2) = 3/5
So
(x+2)/(x+6+2)=3/5
(x+2)/(x+8)=3/5
(x+2)*5=(x+8)*3
5x+10=3x+24
2x=14
x=7
In the end
Numerator= x =7
Denominator=x+6 = 13
So the original number is 7/13
I hope this helps, have a beautiful day
