Answer:
A. g(x) + 3/5x^2 - 3
Step-by-step explanation:
Well we can tell that the parabola is wider than its parent function "y=x^2",
Meaning x is now a fraction or a decimal <u>less than 1</u>.
So we can eliminate choices B and D.
Also we can see that the y intercept is at -3 because thats where the parabola touches the y axis.
<em>Thus,</em>
<em>the answer is choice A. </em><em>.</em>

Answer: False
Explanation:
By definition, the z-score of the random variable, x, is
where
μ = the population mean
σ = the population standard deviation
Because only the sample mean and the sample standard deviations are known, we cannot calculate the z-score. Instead, we can calculate the Student t-test statistic.
