Differentiating Exponential Functions In Exercise, find the derivative of the function.<br> y = x2ex

I am Lyosha [343]

Answer:

$y' = xe^{x}(2 + x)$

Step-by-step explanation:

If we have a product function y, in the following format

$y = f(x)*g(x)$

This function has the following derivative

$y' = f'(x)*g(x) + g'(x)*f(x)$

In this problem, we have that:

$y = x^{2}e^{x}$

$f(x) = x^{2}, f'(x) = 2x, g(x) = e^{x}, g'(x) = e^{x}$

The derivative of the function is:

$y' = f'(x)*g(x) + g'(x)*f(x)$

$y' = 2xe^{x} + x^{2}e^{x}$

$y' = e^{x}(2x + x^{2})$

$y' = xe^{x}(2 + x)$

A sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's p

charle [14.2K]

Answer:

So the value of the test statistic is -0.85.

Step-by-step explanation:

We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.

We get that:

$n=1800\\\\p_1=53\%=0.53\\\\p_2=54\%=0.54\\$

We calculate the standar deviation:

$\sigma=\sqrt{\frac{0.53 \cdot (1-0.53)}{n}}=\sqrt{\frac{0.53 \cdot 0.47}{1800}}=0.01176$

We calculate the value of the test statistic:

$z=\frac{p_1-p_2}{\sigma}=\frac{0.53-0.54}{0.01176}=-0.85$

So the value of the test statistic is -0.85.
