Answer:
Step-by-step explanation:
<u><em>The correct expression is</em></u>
we know that
substitute in the expression above
The first step in solving the problem is to distribute the 8. We know this because of the system or order of operations as well as the distributive property.
8(2+7c)=-19
16+56c=-19
The next step in solving is to isolate the variable, which we can do by performing the opposite operations of the values
16+56c=-19
-16 -16
56c=-35
/56 /56
c=-35/56
Finally, we should put our equation in simplest form.
c=-35/56
c=-5/8=-.625
Using the math above, we can see that the value of the variable is -5/8 or -.625.
Amount used = $25 - $23.35 = $1.65
Number of minutes used = $1.65 ÷ $0.11 = 15 mins
Answer: 15 mins
Answer: present statistical information in clear, meaningful terms.
Step-by-step explanation:
When using statistics, the information gathered should be presented in such a way that it is clear and meaningful as this would allow for the data to be tested using various statistical measures.
If data is unclear, the measures used for the test could be negatively impacted such that the results would not represent the most accurate of interpretations.
