Answer:
B. 37
Step-by-step explanation:
You first find the median of the entire set which is 46. Then find the median of the lower half of the set which is 27. Then find the median of higher part of the data set which is 64. Then you do 64-27=37.
Hope that helped a little bit :)

379 * 8 = 3032
3032 lies between 3031 and 3033
The measure of BD ≈ 5.36
<u>Step-by-step explanation</u>:
- The side BC = BD+DE+EC.
- The measure of BC = 20 and DE ≈ 9.28
- The angles ∠BD and ∠EC are both equal to 15°
- If the angles are same, then their sides are equal.
Let 'x' be the measure of BD and EC.
BC = x+9.28+x
20 = 9.28 + 2x
2x = 20-9.28
x = 10.72/2
x = 5.36 (approx.)
∴ The measure of BD ≈ 5.36
Answer:
29
Step-by-step explanation:
The n th term of an arithmetic sequence is
• 
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
d = 1 - 7 = - 5 - 1 = - 6 and a₁ = 7, = - 161, hence
7 - 6(n - 1) = - 161 ← solve for n
7 - 6n + 6 = - 161
13 - 6n = - 161 ( subtract 13 from both sides )
- 6n = - 174 ( divide both sides by - 6 )
n = 29
There are 29 terms in the sequence
