Answer:
y
Step-by-step explanation:
The expression
y = f(x)
tells you that y is the dependent variable, and that it depends on x, the independent variable. The <em>independent</em> variable is always the function argument. Any variable that depends on that is the <em>dependent</em> variable.
Answer:
B) false D) true E) true
Step-by-step explanation:
Plug in numbers to disprove the first one.
Area formula for triangles says D is true
It's the Pythagorean's Theorem for Heaven's sakes.
Use the formula (zy)i<span> = (y</span>i<span> – ȳ) / s </span>y<span> and calculate a standardized value for each y</span>i<span>. Add the products from the last step together. Divide the sum from the previous step by n – 1, where n is the total number of points in our set of paired data. The result of all of this is the correlation coefficient </span>r<span>.</span>
A logarithm of a number is the exponent to which the base of the logarithm must be taken to equal the number.
Example the logarithm (log) to the BASE 10 of 100 is 2 because
10^2 = 100
The log to base 10 of 1000 = 3 as 1000 = 10^3
The log to the base 3 of 9 is 2 because 9 = 3^2
- or we can say 2 is the log to base 3 of 9.
1/5 = 20%
% sponge cakes = 100 - 50 - 20 = 100 - 70 = 30% Answer
