3/14 and 19/63 whats the LCM
levacccp [35]
Factor them and find the common grouping

3/14
3 is prime so no factoring of this fraction

19/63, 63 is prime so no factoring


if ya wanted the least common denomenator then
14 and 63
14=2*7
63=7*9
so the least common denomenator would be 2*7*9=126
3/14 and 19/63 turns into 27/126 and 38/126

Which term can be added to the list so that greatest common factor of the three terms is 12h^3? 36h^3 12h^6. 6h^3. 12h^2. 30h^4.
Juliette [100K]

Answer:

Last Option 48h^{5}.

Step-by-step explanation:

In this question we will do the factors of given two terms then we will do the common factors of all the terms given in answer to match with.

Common factors of 36h³ = 1×2×2×3×3×h×h×h

Common factors of 12h^{6} = 1×2×2×3×h×h×h×h×h×h

In these two terms greatest common factor Of these two terms is = 1×2×2×3×h×h×h = 12h³

Therefore the third term will be the number which has the greatest common factor = 12h³

So the given terms are

6h³ = 1×2×3×h×h×h

12h² = 1×2×2×3×h×h

30h^{4} = 1×2×3×5×h×h×h×h

48h^{5} = 1×2×2×2×2×3×h×h×h×h×h

Therefore the greatest common factor of the term which matches with 12h³ is 48h^{5}

Find the median and mean of the data set below: 30, 39, 24, 19, 18 Median Mean​
Eva8 [605]

Answer:  mean=26 , median=24

Step-by-step explanation:

Mean=Sum of all values/number of values

mean= 30+39+24+ 19+18/5

         = 130/5

 mean=26

Median

arrange data in order

    18,19,24,20,39

In the case of ungrouped odd-numbered data, the number that  divided data into 2 equal parts is called the median.

so median=24
