Answer:
This can be solved like this:
4x-3x+9=20
<em>Solving 4x-3x</em>
x+9=20
Transposing +9
x=20-9
And now we have, x=11
We can simplify the ratio 12 : 4 by dividing both terms by the greatest common factor (GCF).
The GCF of 12 and 4 is 4.
Divide both terms by 4.
12 ÷ 4 = 3
4 ÷ 4 = 1
Therefore:
12 : 4 = 3 : 1
Answer: C 44.04%
Step-by-step explanation:
in a normal distribution,
P(Z>z)= 1-P(Z<z) (*)
Here , we need to find : P(Z>0.15)
By using (*) , P(Z>0.15)=1- P(Z<0.15)
= 1- 0.5596 [By p-value table]
= 0.4404
= 44.04% [multiply 100 to convert into percent]
∴ the probability that a data value will fall above the data value associated with a z-score of 0.15 = 44.0%
hence, correct option : C 44.04%
