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:
Here is the answer. Solved
X= number of adult tickets sold
y= number of kids tickets sold
7x+20y=236
21x+50y=618
solve for x
Answer:
h=14.9966
Step-by-step explanation:
1. The formula of the volume is:
V=
2. So you have to substitute the the data that you have:
3533.5
=
3. To have the area of the base (ab) you have to get the formula of the circle's area and solve:
A=
(
)
A=(
)
A=3.1416(225)
A=706.86in
4. Now you have the area of the base:
3533.5=
5. In this step you are going to clear the variable which is the heigh (h) and solve as an equation:
3533.5=
3533.5(3)=706.86(h)
=h
h=14.9966
The result may vary depending on the value of that you use,
Answer:
x = -1.4.
Step-by-step explanation:
3(x - 6) - 8x = -2 + 5(2x + 1)
3x - 18 - 8x = -2 + 10x + 5
-5x - 10x = 18 - 2 + 5
-15x = 21
x = -21/15
= -1.4 answer
