Let the lowest score be x.
<u>The 3 consecutive even scores are:</u>
1st score = x
2nd score = x + 2
3rd score = x + 4
-
<u>Sum of their score is 270:</u>
x + (x + 2) + (x + 4) = 270
-
<u>Solve x:</u>
x + (x + 2) + (x + 4) = 270
x + x + 2 + x + 4 = 270
3x + 6 = 270
3x = 264
x = 88
-
<u>Find their scores:</u>
1st score = x = 88
2nd score = x + 2 = 88 + 2 = 90
3rd score = x + 4 = 88 + 4 = 92
-
Answer: The scores are 88, 90 and 92
1-39 ODD:
1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39
Now you'd add them all up.
1+3+5+7+9 = 25
11+13+15+17+19 = 75
21+23+25+27+29 = 125
31+33+35+37+39 = 175
Add the totals:
25+75+125+175
The answer would be 400.
Management information system requires tables, Tables are used only if a person is trying to analyse data and understand its business by summarizing.It is the 1st step of data analysis collecting data. Scatter plot is used when there is a question of association of two or three variable.
Step-by-step explanation:
- Table is the matrix to stack up the data in there respective columns.
- It is the most important setup to analysis.
- It's better used collecting data for any projects or business.
- Tables are even used for Bio statistics and Analytics.
- Databases uses tables for one query table to another query table.
- Scatter plot is dotted plot which analyse two variables.
- Example if a project is eating chocolates in gram in x axis.
- Gaining weight in y axis two variables are used to predict and outcome.
- If a person eats this amount of chocolate it will gain this wait.
- Association rules, contingency statistics and rest.
in slope intercept form :
y = 2x - 19
( I think )
Two out of four can be represented as:
2/4
OR
1/2
