Answer:
Interpolation refers to using the data in order to predict data within the dataset. Extrapolation is the use of the data set to predict beyond the data set.
Step-by-step explanation:
Extrapolation and interpolation are both used to estimate hypothetical values for a variable based on other observations. There are a variety of interpolation and extrapolation methods based on the overall trend that is observed in the data.
Answer:
3.15
Step-by-step explanation:
10.08 / 3.2 = 3.15
Since 1/2 =2/4 = 4/8 = 5/10, only Mary drank less than half of her juice. 3/8 is less than 4/8
Combine like terms so 3x + 3x= 6x
Then put the minus signs with the 4 and 5 and add them together so -4+ -5= -9
Now you have 6x=-9 So you divide by 6 on both sides canceling out 6
but 9 divided by 6 doesn't go into a specific number therefore it has no solution which is a possible answer
If we assume that Jane spent $ x on the black pack
Then the cost of the book is $ 20 less that twice the cos of the black pack,
Then twice the cost of black pack is 2x, then less $ 20 we get 2x-20
Hence , 60 =2x-20
solving for x
x = 40
Therefore, the cost of the black pack is $40.
