Answer:

The dependent or output variable is f

Step-by-step explanation:

The given function is

f(x) = 10 - x

We want to to determine, the output or dependent variable.

Recall that we can rewrite this function as:

y = 10 - x

Here we can clearly see that y is the output or dependent variable.

But do you know

y = 10 - x \: means \: y(x) = 10 - x  \: {?}

This tells us that y is a function of x.

Similarly,

f(x) = 10 - x

means f is a function of x.

Therefore the output variable is f.

Answer:x

Step-by-step explanation:x is the input, or independent variable and f(x) is the output, or dependent variable or quantity. f(2) represents the output (y-value) when x = 2. The value of f(2) is 2.

qaws [65]

Answer: 9000$

Step-by-step explanation:

Let 's use the formula to find the vertex of the parabola:

ax²+bx+c=0

\displaystyle x_v=-\frac{b}{2a}  \\\\  Where :\\\\ y_v- maximum \ \  income \\\\ y_v=a(x_v)^2+bx_v+c \\\\ Then \ in \ \ our \ \ case : \\\\ -4p^2+1200p =0 \\\\ x_v=-\frac{1200}{-4\cdot 2} =150 \\\\  y_v=-4\cdot (150)^2+150\cdot 1200 \\\\ y_v=150\cdot 1200-150\cdot 600 \\\\ y_v=600\cdot 150=\bf 9000 \

pantera1 [17]

Answer:

Step-by-step explanation:

Given that in  a study of a weight loss​ program, 4 subjects lost an average of 48 lbs.

It is found that there is about a 32​% chance of getting such results with a diet that has no effect.

The results do not appear to have statistical significance.  The reasons are

1) Sample size of 4 is very small not even meeting the bare minimum

2) Sample of 4 cannot be taken to represent the population

3) Whether bias was there in the selection of sample is not known.

4) Std deviation is not considered which is very important while concluding results.
