Answer:
11
Step-by-step explanation:
The range of a data set is the difference between the largest number and the smallest number in the set. First put the numbers in order from smallest to largest then take the last number minus the first number.
10,12,13,15,17,18, 21. 21-10=11
Answer:
lower limit is n=1
upper limit is n=18
n=1 to 18∑(7n-4)
Number of beads = 1125
Step-by-step explanation:
Given series is 3+10+17+24.....
we find the formula to find nth term(explicit formula)
first term (a1) = 3
common difference (d)= 7
total of 18 rows
So we find sum for n =1 to 18
lower limit is n=1
upper limit is n=18
n=1 to 18∑(7n-4)
(b) to find total number of beads we apply sum formula
n=18, a=3, d= 7
S= 9(125)=1125
Number of beads = 1125
To solve this problem, you must multiply the 1/3 cup of water needed for one flower, by 9.
1 9 9
--- * ----- = ---- = 3 cups
3 1 3
First, if you convert the improper fraction 9/2 to a mixed number, it will be equal to 9/2.
9/2 = 4 1/2
And if you multiply the top and bottom of a fraction with an integer number, you will have a fraction that is equal to fraction you began with.
I'll use 5 for this example.
9/2 * 5/5 = 45/10
