In Exercise, find the derivative of the function. y = 5ex + 2

Mathematics
1 answer:
ser-zykov [4K]3 years ago
8 0

Answer:

\dfrac{dy}{dx} = 5e^x

Step-by-step explanation:

We are given the following in the question:

y = 5e^x + 2

We have to find the derivative of the given function.

Formula:

\dfrac{d(e^x)}{dx} = e^x

Derivative of a constant is zero.

Derivation takes place as:

\dfrac{dy}{dx} = \dfrac{d(5e^x + 2)}{dx}\\\\=5\dfrac{d(e^x)}{dx} + \dfrac{d(2)}{dx}\\\\= 5e^x

\dfrac{dy}{dx} = 5e^x

The scores on the Wechsler Adult Intelligence Scale are approximately Normal with mean = 100 and standard deviation = 15The prop
gregori [183]

Answer:

b) 0.025

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 100, \sigma = 15

The proportion of adults with scores above 130 is closest to

This proportion is 1 subtracted by the pvalue of Z when X = 130. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{130 - 100}{15}

Z = 2

Z = 2 has a pvalue of 0.9772

1 - 0.9772 = 0.0228

Closest to 0.025

So the correct answer is:

b) 0.025

How many radii does a circle have? Explain.
timurjin [86]
Radii is defined as the line joining the centre of the circle to a point on the circumference
as there are infinite points on a circle
therefore there are infinite number of radii and hence there is no fixed number.
