Calculation of x:
we can see that
x is hypotenuse
so, we can use pythagoras theorem
Calculation of y:
we can use tan formula to find it
opposite=8
adjacent=10
Calculation of z:
we know that sum of all angles of any triangle is 180
...........Answer
It will be PEMDAS so first you see id there is and parentheses if so then you will solve that first if not the go to E for exponents you will solve those next then M for multiplication and D for division and then A for addition and then S for subtraction do you need any more help?
Answer:
-11/15 is the greatest because ita in negative
Y=4x+5.
4 is the gradient
+5 is the y intercept
In the research of Professor Nwamabi the use of air conditioning represents independent variable.
Given 100 participants are randomly selected in a research in which effects of air conditioning on sleep habits is studied.
Dependent variable is the variable whose value is dependent on the other variables like increase in profit and production.
Independent variable is the variable whose value is not dependent on the other variables.
In the research of Professor Nwamabi in which he is examining the effects of air conditioning on sleep habits, use of air conditioning represents independent variable. In this study the effect is on sleep habits means the value of sleep habits will change due to use of air conditioning. It shows that the use of air conditioning is not depending on other variable in the research.
Hence the use of air conditioning represents the independent variable.
