Answer:
187
Step-by-step explanation:
A number m is such that when it is divided by 30, 36 and 45 the remainder is always 7.
We should first find the LCM of 30, 36 and 45
We get that the LCM of the three numbers is 280 (working attached).
So now;
= 6
= 5
= 4
But we need a number that leaves a remainder of 7 so we add 7 to 180 to get; 180 + 7 = 187.
Answer:
Dependent and independent Variable.
Step-by-step explanation:
Dependent and independent Variable.
- The two variables in an experiment are independent and dependent variable.
- Usually, the dependent variable is denoted by y and the independent variable a re denoted by
- The dependent variable depends on independent variable in an experiment and thus cannot be controlled.
- On the other hand we can change or control the independent variables to test effect on dependent variable.
- As the independent variable are changed, we observe corresponding changes in the dependent variable.
- Example: Let money spend be the dependent variable. It depends on an independent variable of shopping. We may control or change or shopping habits to see the changes in the money spent. Money spent totally depends in the amount f shopping done.
