A sample of computer tablet batteries has a mean battery life of 28 months and standard deviation of 4 months. What is the lifes

Ulleksa [173]

Using the Empirical Rule, it is found that the lifespans, in months, are given by:

1. 24 and 32.

2. 20 and 36.

3. 16 and 40.

<h3>What is the Empirical Rule?</h3>

It states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

Hence, considering the mean of 28 months and the standard deviation of 4 months, the life spans are given by:

1. 24 and 32.

2. 20 and 36.

3. 16 and 40.

Write the equations after translating the graph of y = |x|: one unit up,

Tatiana [17]

Answer:

$g(x) = |x| + 1$

Step-by-step explanation:

Given

$y = |x|$

Required

Translate 1 unit up

Start by replacing y with f(x)

$f(x) = |x|$

To translate an the graph of an absolute function upward, you make use of the formula;

$g(x) = f(x) + k$

Where k is the number of units

In this case; $k = 1$

Hence;

$g(x) = f(x) + k$

Substitute $k = 1$

$g(x) = f(x) + 1$

Substitute $f(x) = |x|$

$g(x) = |x| + 1$

Hence, the resulting equation is $g(x) = |x| + 1$

Slope Formula: $\displaystyle m = \frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Identify

Point (0, -4)

Point (10, 3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m = \frac{3--4}{10-0}$
[Fraction] Subtract: $\displaystyle m = \frac{7}{10}$
