Riley’s parent got a cell phone plan that has a $40 monthly fee for the first phone. For each extra phone, there is a $15 phone
1 answer:
The simplified expression is 40 + 25e
<h3><em><u>Solution:</u></em></h3>Given that, Riley’s parent got a cell phone plan that has a $40 monthly fee for the first phone
For each extra phone,
Phone service charge = $15
Text service charge = $10
<em><u>The expression that represents the total phone bill in dollars is given by:</u></em>
40 + 15e + 10e
Where "e" is the number of extra phones
We are asked to simplify the expression
Combine the like terms. Here like terms are 15e and 10e
Therefore, add 15e and 10e
Thus the simplified expression is 40 + 25e

Answer:
D.No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.
Step-by-step explanation:
(a) Range is the difference between the smallest and largest observation.
Here Smallest observation = 0.63
and Largest observation = 1.48
⇒ Range = 0.85
(b) Standard Deviation is calculate by,
where, is mean of the observation.
Here, Mean = 0.988
⇒ Standard Deviation = 0.313
(c) Variance is the square of Standard deviation.
Thus, Variance = (Standard Deviation)² = 0.098
(d) Here last option(D) is true i.e. No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.
It has been determined that the number of fish f(t) that can be caught in t minutes in a certain pond using a certain bait is f(t) = .25t + 1, for t > 10. Find the number of fish that can be caught if you fish for 15 minutes. Round your answer to the nearest whole number.
