Answer 1

Answer:

Answer:

The standard deviation is 9.34

Step-by-step explanation:

First we need to find mean of the sample:

$m=(23.9+15.3+40.2+30.3+12+22.8)/6=24.08$

Standard deviation will be like below:

$d=√((x-m^2)/6)=9.34$

Answer:

I will answer here because I am glitching.

Step-by-step explanation:

1. 1.36 < $√(2)$ < 2.45

2. 1.65 < $√(3)$ < 2.34

3. 1.65 < $√(4)$ < 2.34

4. 2.14 < $√(5)$ < 3.56

I need an equation for this problem: A small golf club manufacturer is concerned about their monthly costs. The shop has fixed costs of $23,250 per month to run in addition to the $145 in materials per set of golf clubs produced. If the company wants to break-even making 100 sets of clubs per month, what should they charge for each set? Recall that the break-even point is when revenue equals costs. I solved it and the answer is 377.50 but i need a proper equation for my answer

Answers

100 = number of sets of clubs manufactured per month
S = sell-price for a set of clubs

Expenses per month = 23,250 + 145(100) = 37,750

Revenue per month = 100 S

Break-even when Expenses = Revenue

100 S = 37,750

One question: How did you solve it without an equation ?
