Write as a multiplication sentence.
5/6 divided by 1 1/2
Remember that
1 1/2=1+1/2=3/2
so
Answer:
2 : 6 = 14 : 42
32 : 64 = 12 : 24
Step-by-step explanation:
This is ratios.
2 : 6 = 14 : 42 is because 2 can go into 14, 7 times, so that makes it a multiple of 2. Than you just multiply the 6 by 7 that will get you to 42.
32 : 64 = 12 : 24 is because 12 is doubled on the other side to get 24, so you just double 32 and get 64.
Hope this helps!!!

Answer:
9.5
Step-by-step explanation:
Find the sample variance for the data 9,12,9,14,6. Round the answer to one decimal place. Sample variance.
Step 1
We find the Mean of the numbers
Mean = Sum of terms/ Number of terms
Mean = 9+12+9+14+6/5
= 50/5
= 10
Step 2
We find the sample variance
Formula =
(x - Mean)²/n - 1
n = 5
= (9 - 10)²+(12 -10)²+(9- 10)²+(14-10)²+(6-10)²/5 - 1
= 1+ 4+ 1+ 16+16/5 - 1
= 38/5 - 1
= 38/4
= 9.5
Therefore, Sample variance = 9.5
