Which transformations would affect the starting point of a square root function?

Answer:

There are at least two transformations that would affect the starting point of a square root: (i) <em>Horizontal translation</em>, (ii) <em>Vertical translation</em>.

Step-by-step explanation:

Let the square be represented by the following function:

f(x) = \sqrt{x},\,\forall \,x \ge 0 (1)

Which means that function has only valid solutions for every element of x greater or equal to 0. In particular, the starting point is x = 0.

We can change the starting point of this function by horizontal translation, which is defined below:

g(x) = f(x - a), \,\forall \,x \ge a (2)

In other words, we create the resulting function:

g(x) = \sqrt{x-a}, \,\forall\,x \ge a (3)

Another, possibility is using a vertical translation, whose definition is defined below:

h(x) = f(x)+c,\,\forall \,x \ge 0 (4)

In other words, we create the following function:

h(x) = \sqrt{x} +c (5)

Hence, there are at least two transformations that would affect the starting point of a square root: (i) <em>Horizontal translation</em>, (ii) <em>Vertical translation</em>.

kompoz [17]

Answer:

0.62% probability that a random sample of 16 bulbs will have an average life of less than 775 hours.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, a large sample size can be approximated to a normal distribution with mean \mu and standard deviation \frac{\sigma}{\sqrt{n}}

Normal probability distribution.

Problems of normally distributed samples can be 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 = 800, \sigma = 40, n = 16, s = \frac{40}{\sqrt{16}} = 10

Find the probability that a random sample of 16 bulbs will have an average life of less than 775 hours.

This probability is the pvalue of Z when X = 775. So

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

Z = \frac{775 - 800}{10}

Z = -2.5

Z = -2.5 has a pvalue of 0.0062. So there is a 0.62% probability that a random sample of 16 bulbs will have an average life of less than 775 hours.
