Answer:
X=-3
Step-by-step explanation:
Is that what you need?
The distribution is not a standard normal distribution.
We know that the variable (X) usually obeys and follows a standard normal distribution provided that the summation of (X) is zero and the variance of the random variable V(X) = 1.
Mathematically:
E(X) = 0 and V(X) = 1
Given that;
- the mean which follows a normal distribution (X) = 4.5338 g, and
- the standard deviation SD(X) = 0.1039 g
As such, the distribution is not a standard normal distribution.
Therefore, we can conclude that the distribution is not a standard normal distribution.

Answer:
4. (4, 5)
Step-by-step explanation:
Use substitution to put the value for y in the second equation.
-3x +4(5) = 8
-3x = -12 . . . . . . . subtract 20
x = 4 . . . . . . . . . . divide by -3
The solution is (x, y) = (4, 5).
