Answer:
The mean reflects the best measure of the center
Step-by-step explanation:
12, 13, 13, 14, 21, 22, 23
Median: 14
Mean: 16.86
The mean reflects the best measure of the center
First we find the common difference.....do this by subtracting the first term from the second term. (9 - 3 = 6)...so basically, ur adding 6 to every number to find the next number.
we will be using 2 formulas....first, we need to find the 34th term (because we need this term for the sum formula)
an = a1 + (n-1) * d
n = the term we want to find = 34
a1 = first term = 3
d = common difference = 6
now we sub
a34 = 3 + (34-1) * 6
a34 = 3 + (33 * 6)
a34 = 3 + 198
a34 = 201
now we use the sum formula
Sn = (n (a1 + an)) / 2
S34 = (34(3 + 201))/2
s34 = (34(204)) / 2
s34 = 6936/2
s34 = 3468 <=== the sum of the first 34 terms
Solution:
<u>Note that:</u>
- 1 pair of mittens = $3
- Kendra = $50
<u>We already know:</u>
- The closest number to 50 and is divisible by 3 is 48.
=> x pair of mittens = $3x = 48
=> $3x = 48
=> x = 48/3
=> x = 16
Kendra can buy <u>16 mittens.</u>
the factors and prime factorization of 14 and 28. (The biggest common factor number is the GCF number) So the greatest common factor 14 and 28 is 14.Jul
This is saying, when x is 6, what is the value of you. f(x) is y
y=3(6)-5
y=18-5
y=13
Answer is 13
