Answer:
The first coal mine worker is 650 feet <em>below, </em>so they're -650 ft.
The second coal mine worker is 7 feet <em>above,</em> so they're +7 ft.
| -650 | = 650 ft
| 7 | = 7 ft
650 > 7, so the first worker is farther from the surface.
The events 'select a plain pencil' and 'select a color pencil' are independent. therefore the probability of both occurring is the product of their probabilities:
The answer is 3/20 or 0.15.
Compared? By finding the LCM of the consequents of both the ratios, divide the LCM with the consequents, and finally, multiply both the numerator and the denominator of both the ratios with the answer to find out the compared ratio
I'm assuming you meant a 5% discount.
2 * $3.50 = 7
4 * 3.25 = 13
2 * 1.90 = 3.80
7 + 13 + 3.8 = 23.8
0.05 * 23.8 = 1.19
23.8 - 1.19 = 22.61
Nathaniel spent $22.61.

Answer:
Step-by-step explanation: This is a question under linear regression analysis.
The question is trying to relate sales (in $1000) and and advertising.
Both sales and advertising are variables and are connected by the equation
Y = 32x + 8
Which is a linear regression equation of 2 variables.
Where x is the independent variable which represents advertising in this case and Y is the dependent variable which represents sales.
At $1 of adverts, we have $40 of sales.
We just simply put the fact that x = $1 (advertising) into the linear regression equation, we have the value of Y ( sales)
Y = 32(1) + 8
Y = 32 + 8
Y = $40.
