Answer: 1120
Step-by-step explanation:
Given: Size of the population in the study = 1200
Also they revealed that 12 out of every 180 frogs in the population have spots on their back.
Thus we have fraction
Hence, of total frogs have spots.
Now,
Therefore, 80 out of 1200 frogs in the population have spots.
Thus, the number of frogs in the population do not have spots = 1200-80=1120
Answer:
A=lw+l(w
2)2+h2+w(l
2)2+h2
Step-by-step explanation:
We all are familiar with (x,y) coordinate plane where some lines or curves are drawn. These curves are drawn or made up using some (x,y) points. These values of (x,y) points satisfy the equation of curves.
The equation of x and y variables is called a Relationship. Now, a Function is a "special relationship of x and y variables" where each input x has a single answer for output y.
In other words, we can say any relation y=f(x) would be a "Function" if and only if each value of x input give us a unique value of y output from the equation. No two values of y can be output of same x-value input.
For example:- y = f(x) = 2x is a Function because each value of x would give unique answer for y. x=4 gives y=8.
Another example is:- y = f(x) = √x is "not a function" because one-value of x would give two answers of y. x=4 gives y= -2 and y=2.
