Complete question is;

The function f(x) = (25000 + 280x)/x models the average cost per unit, f(x), for Electrostuff to manufacture x units of Electrogadget IV. How many units must the company produce to have an average cost per unit of $390?

Answer:

227 units

Step-by-step explanation:

We are given the function;

f(x) = (25000 + 280x)/x

Where;

f(x) is the average cost per unit

x is the number of units

Now, we want to find out how many units the company must produce to have an average cost per unit of $390.

Thus, plugging $390 for f(x), we have;

390 = (25000 + 280x)/x

When we cross multiply, we get;

390x = 25000 + 280x

390x - 280x = 25000

110x = 25000

x = 25000/110

x ≈ 227

Answer:

Relative frequencies

Growth mind set fixed mind set Total

Attendance

every practice 0.7 0.3 1

missed at-least

one practice 0.1344 0.8656 1

Step-by-step explanation:

Growth mind set fixed mind set total

Attendance

every practice 28 12 40

missed at-least

one practice 9 58 67

Relative frequencies

Growth mind set fixed mind set Total

Attendance

every practice $\frac{28}{40} = 0.7$ $\frac{12}{40} = 0.3$ 1

missed at-least

one practice $\frac{9}{67} = 0.1344$ $\frac{58}{67} = 0.8656$ 1

Final answer:-

Relative frequencies

Growth mind set fixed mind set Total

Attendance

every practice 0.7 0.3 1

missed at-least

one practice 0.1344 0.8656 1
