Answer:
R = 
Step-by-step explanation:
I = 
( multiply both sides by 100 to clear the fraction )
100I = PRT ( isolate R by dividing both sides by PT )
= R
Answer:
Step-by-step explanation:
Answer:
This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
Step-by-step explanation:
Given
Time ------ 0 ----- 2 ------- 4 ----- 6 -----8.
Cost ------- 0 ----- 10 ----- 20 ----30 ----40
Required
Explain why or why not it is a direct variation?
First, we calculate the slope of the table.
Where:
So:
Next, we determine the equation using
<em>The above shows a direct variation with 5 as its constant of proportionality of variation.</em>
Answer:
−7.1s+8
Step-by-step explanation:
First Distribute
=−0.3s+−2+(2)(5)+(2)(−3.4s)
=−0.3s+−2+10+−6.8s
Combine Like Terms:
=−0.3s+−2+10+−6.8s
=(−0.3s+−6.8s)+(−2+10)
=−7.1s+8
Answer:
Center
Step-by-step explanation:
A numerical data can be defined as a data set that is expressed in numbers only or a data set consisting of numbers rather than words. A numerical data is also known as a quantitative data.
Basically, numerical data are classified into two (2) main categories and these are;
1. Discrete data: a discrete data is a data set in which the number of possible values are either finite or countable. For instance, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
2. Continuous data: a continuous data is a data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.
A measure of center for a numerical data set summerizes all of its values with a single number.
On the other hand, a measure of variation gives a description of how the values of a numerical data varies with a single number.
