<h2>Explanation:</h2>
- The domain of a function is defined as the set of all input values. Or in other words the set of all first element of ordered pairs.
In the given input-output table, the set of all input values will be the domain of the given function.
The life span of the battery can be expected 98% of the batteries to meet the guarantee will be 149.3 hours.
<h3>What is the z-score?</h3>
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The z-score is given as
z = (x - μ) / σ
Where μ is the mean, σ is the standard deviation, and x is the sample.
Many electronic devices use disposable batteries, which eventually have to be replaced.
The mean is 140 hours and the standard deviation is 4 hours.
The marketing department wants to write a guarantee for the battery life.
The life span of the battery can be expected 98% of the batteries to meet the guarantee will be
Then the z value for 98% is 2.326.
Then the life span will be
2.326 = (x - 140) / 4
9.304 = x - 140
x = 149.3 hours
The life span of the battery can be expected 98% of the batteries to meet the guarantee will be 149.3 hours.

First we know that a dozen is 12
so She makes 12×15 cookoes which is
180 cookies
so lets put it in an equation.
36 cookies = 1 cup butter
180 cookies = X
The criss cross method
36 X = 180 cup of butter (notice here that the cookie cancelled out)
dividing each side by 36 we get
5 cups of butter
