Answer:
it would be in the 100eds place
Step-by-step explanation:
It may be can be number 1 (a)
By applying z-score formula we got that if a reporter determines a mean order time of 63 minutes then value o Z is 1.19
<h3>What is standard deviation?</h3>
Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value
Here given that
The owners of an eyeglass store claim that they fill customers' orders, on average, in 60 minutes with a standard deviation of 15. 9 minutes. Based on a random sample of 40 orders, a reporter determines a mean order time of 63 minutes
mean=μ=60
standard deviation=σ=15.9
number of sample=n=40

Now we can calculate z by z-score formula as

By applying z-score formula we got that if a reporter determines a mean order time of 63 minutes then value o Z is 1.19

A "rational expression" is a fraction in which the numerator and the denominator are both polynomials. The sum of two such expressions will always produce another such expression, viz.,
<span>p(x)/q(x) + r(x)/s(x) = [p(x)s(x) + q(x)r(x)] / [q(x)*s(x)]. </span>
<span>The numerator and denominator of the sum will both be polynomials when fully expanded</span>
Answer:
<h3><u>Required Answer</u><u>:</u><u>-</u></h3>
Every number raised to a negative exponent will have a value smaller than 1.
<h3><u>Reason</u><u> </u><u>:</u><u>-</u></h3>
- It will only be negative if the number is negative with an odd exponent.
- what you're actually doing is dividing instead of multiplying.
