The rule is to put them in order
1. 5+6>8
6+8> 5
5+8> 6
2. 10+10> 2
10+2> 10
10+2> 10
3. 19+ 34> 15
19+ 15 > 34 not correct
34+15 > 19
4. 3+16 > 14
3+14> 16
14+16 >3
Answer is 3 <33
Sample means show a large variation because the data set has a large range. When there is a large variation in the data set, the sample means also will have a large variation. Jennie included small values in her sample, while Charles included high values.
Answer:
This is the given information for which system of equations would be used to find out how many dimes and quarters Amir has?
x = dimes x = 0.10 or 0.1
y = quarters y = 0.25
31 coins
worth $5.20 = 5.2
x + y = 31
0.1x + 0.25y = 5.2
Step-by-step explanation:
a. Notice that
1/(1*2) = 1/2 = 1 - 1/2
1/(2*3) = 1/6 = 1/2 - 1/3
1/(3*4) = 1/12 = 1/3 - 1/4
and so on, which suggests the n-th term of the sum can be written as
Then the sum itself is telescoping:
b. The proof is trivial:
so the formula found in (a) is correct.
