Answer:
A
Step-by-step explanation:
We have the equation:
And we want to determine whether or not this represents a direct proportion.
First, let's solve for <em>y. </em>Multiply both sides by 8/3:
Remember that direct proportions must pass through the origin point on a graph. In other words, their <em>y-</em>intercept or constant value is zero.
Since the constant value here is not zero (it is 16/3), the equation is not direct proportion.
Our answer is A.
The standard deviation is 1.43 below the mean
<h3>How to determine the number of standard deviation?</h3>The given parameters are:
Mean = 98.249
Standard deviation = 0.733
x = 97.2
To calculate the number of standard deviation below the mean, we use
So, we have:
Evaluate the like terms
Divide both sides by -0.733
n =1.43
Hence, the standard deviation is 1.43 below the mean
