<span>x + y = 24
</span><span>3x + 5y = 100
</span>
Using the graphic method, we can easily see that the solution of the system is
(x,y) = (10,14)
Which means that there are 1<span>0 three-point questions and 14 five-point questions</span>
Answer: 0.547
Step-by-step explanation:
As per given , we have
Population mean =
Population standard deviation=
Sample size : n= 36
We assume that number of apps used per month by smartphone owners is normally distributed.
Let be the sample mean.
Formula :
The probability that the sample mean is between 19.5 and 20.5 :-
[using standard normal distribution table for z]
Hence, the required probability = 0.547
= 2a/b²(x + 1)
y = a/u² = a/ (b²/(x + 1)²) = a/b² (x + 1)²
differentiate using the ' chain rule'
= 2a/b² (x + 1)
