84 gallons/(2.8 gpm) = 30 minutes
Answer:
8
Step-by-step explanation:
x - 3 = 5
x = 5 + 3
x = 8
Therefore, the number is 8.
Answer:
(r o g)(2) = 4
(q o r)(2) = 14
Step-by-step explanation:
Given


Solving (a): (r o q)(2)
In function:
(r o g)(x) = r(g(x))
So, first we calculate g(2)




Next, we calculate r(g(2))
Substitute 9 for g(2)in r(g(2))
r(q(2)) = r(9)
This gives:


{

Hence:
(r o g)(2) = 4
Solving (b): (q o r)(2)
So, first we calculate r(2)




Next, we calculate g(r(2))
Substitute 3 for r(2)in g(r(2))
g(r(2)) = g(3)




Hence:
(q o r)(2) = 14
Step-by-step explanation:
2112 + 2212 + 2312 / 4 leaves no remainder, as already the individual numbers could be divided by 4 without remainder.
2113 = 2112 + 1
2213 = 2212 + 1
so, we get a remainder of +1 and +1 for these 2 numbers, so we get in total a remainder of +2.
<u>The correct answer is </u><u>all of the above.</u>
Why is the range the most convenient measure of variability?
- Your data's spread from the lowest to the greatest value in the distribution is indicated by the range.
- The calculation of this variability index is the simplest.
- Simply subtract the lowest value from the highest value in the data set to determine the range.
How do you find the range?
- The difference between the lowest and highest values in a list or set is known as the range.
- Put all the numbers in order before determining the range. The lowest number should then be subtracted from the highest.
- The range of the list is provided in the response.
