Answer:
The median is 72
Step-by-step explanation:
The median is the middle of a sorted list of numbers. If there is an odd number of values, the median is the value at the middle. Otherwise, it is the mean between the two middle values.
In this question:
Scores: 86, 67, 62, 82, 64 and 77
Sorted: 62, 64, 67, 77, 82, 86
Middle elements: 67 and 77
Median: (67 + 77)/2 = 72
The median is 72
Answer:
Surface Area > 1500, since its cube
Answer: 3/16 is not equivalent to 3/8
Step-by-step explanation: 3/16 would be like eating 3 pieces of a pie that has 16 pieces whilst 3/8 would be like eating 3 pieces of a pie that has 8 pieces. They are mildly similar but 3/16 is twice as small as 3/8 and henceforth not equivalent.
The third term of the geometric progression will be 1 / 27 with common ratio 2 / 3.
We are given that:
2nd term of geometric progression = 1 / 18
5th term = 4 / 243
Now, we can also write it as:
2nd term = a r ( where r is the common ratio and a is the initial term.)
a r = 1 / 18
5th term = a r⁴
a r⁴ = 4 / 243
Now divide 5th term by 2nd term, we get that:
a r⁴ / a r = ( 4 / 243 ) / ( 1 / 18 )
r³ = 72 / 243
r³ = 8 / 27
r = ∛ (8 / 27)
r = 2 / 3
3rd term = a r²
a r² = a r × r
= 1 / 18 × 2 / 3
3rd term = 1 / 27
Therefore, the third term of the geometric progression will be 1 / 27 with common ratio 2 / 3.
