Answer:
first group = 33
second = 15
Step-by-step explanation:
Let size of second group = x
size of the first group = 3x - 12
x + 3x - 12 = 48
4x - 12 = 48
collect like terms
4x = 48 + 12
4x = 60
x = 15
Substitute for x in the equation for size of the first group
3(15) - 12 = 33
Answer:
The advantages & disadvantages of tables,graphs and words have been explained below.
Step-by-step explanation:
The 3 major representation for finding patterns and making predictions are;
1.Tables
2. Graphs
3. Words
This means we want to find the advantages and disadvantages of using tables, graphs and words for finding patterns and making predictions.
1) Tables: Advantage is that we will be able to directly see the exact effect of the input variable on the output. While the disadvantage is that it's very difficult to see patterns.
2) Graphs: Advantage is that we can easily see the pattern of the representation. However the disadvantage is that we can't see the exact values arising from the effect of the input variable on the output.
3) Words: The advantage is that we can describe the data values in clear terms. However, the disadvantage is that we can't get exact values from just the words.
