Pn(Z>zp)=1−p%
Given a variable X following a normal distribution with mean μ and standard deviation σ, the area below the curve that corresponds to all values that are less than a that is, X<a
is the probability P(X<a). This probability is usually calculated by converting the variable X to a standard normal variable Z (forming z scores) defined by:
The variable Z follows the standard normal distribution with a mean of 0 and a standard deviation of 1.
The standard normal probabilities are typically found by using the standard normal tables or other computational means such as calculators or software.
Pn(Z>zp)=1−p%
Here Pn is the probability for the standard normal variable.

Pounds multiplied by the unit price will solve this problem. Be sure to round your answer to two decimal places; it's money $.
5.62 lbs x $3.49/lb = $19.61
Assuming that it is a square board, she would not have enough. This is because there would be twice as much height and twice as much width. Those numbers add up to far more.
However, if they just have to cover those two sides they will have 0.45 left. You can get this by subtracting the amounts from the overall.
46.25 - 37.5 - 8.3 = 0.45

Answer:
The area of parallelogram ABCD is
Explanation:
Given:
AD = 12 in
To Find:
The area of parallelogram ABCD=?
Solution:
When we construct the parallelogram with the given data, we get a parallelogram formed by 12 cm as one side and an angle with 46 degrees.
The area of the parallelogram can be calculated by 
Substituting the value of a=12 we have
<u>To find the value of b,
</u>
We know that area of a triangle can be expressed as,
So,
Cancelling BD and 2 on both sides we get,
Therefore,
Substituting the value of b,
=78.42
So the area of the parallelogram is
