Answer:
Malik substituted 60 for y instead of x.
Step-by-step explanation:
According to the given situation the computation of error that Malik make first when solving the equation is shown below:-
First, we will find the value of x
x = 625
Now, we have
we will solve the above equation, to find the value of y
24 - 4y = 10
4y = 24 - 10
4y = 14
So, from the above calculation, the correct option is
Malik substituted 60 for y instead of x.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Let X the random variable that represent interest on this case, and for this case we know the distribution for X is given by:
And let represent the sample mean, the distribution for the sample mean is given by:
On this case
Solution to the problem
We want this probability:
The best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
