Answer:
b) 9 in
Step-by-step explanation:
To find median arrange the data in ascending order and count the number of data's. if the total number of data is odd number, then (n/2)th term is the median.
If the total number of data is even, then Average of (n/2)th term and (n/2)+1 th term is the median
Ascending order:
6, 8, 8 , 8 , 9 , 9 , 10 , 11 , 12 , 16
total = 10. so even number
Median = average of 5th term and 6th term
=(9+9)/2
= 18/2
= 9

Answer:
a) 416/100 = 4.16
b) 46/10 = 4.6
c) 406/100 = 4.06
Step-by-step explanation:
a) 4 + 16/100 = 4(100/100) +16/100 = (400 +16)/100 = 416/100 = 104/25
4 + 16/100 = 4 +0.16 = 4.16
__
b) 4 + 6/10 = 4(10/10) +6/10 = (40 +6)/10 = 46/10 = 23/5
4 +6/10 = 4 +0.6 = 4.6
__
c) 4 +6/100 = 4(100/100) +6/100 = (400 +6)/100 = 406/100 = 203/50
4 +6/100 = 4 +0.06 = 4.06

<em>Comment on place value</em>
Since you're familiar with the decimal place-value number system, you know that digits in the ones place are multiplied by 1; digits in the tenths place are multiplied by 1/10 or 0.1; and digits in the hundredths place are multiplied by 1/100 or 0.01. These same multipliers can be represented as powers of 10: 10^0, 10^-1, 10^-2, respectively.
Answer:
a₁₅ = 30
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₅ = 10 and a₁₀ = 20 , then
a₁ + 4d = 10 → (1)
a₁ + 9d = 20 → (2)
Subtract (1) from (2) term by term to eliminate a₁
5d = 10 ( divide both sides by 5 )
d = 2
Substitute d = 2 into (1) and solve for a₁
a₁ + 4(2) = 10
a₁ + 8 = 10 ( subtract 8 from both sides )
a₁ = 2
Then
a₁₅ = 2 + (14 × 2) = 2 + 28 = 30
