A vending machine operator has determined that the number of candy bars sold per week by a certain machine is a random variable with mean 109 and standard deviation 11. His profit on each bar sold is $0.12, and it costs him $10 per week to maintain the machine and rent the space for it. What are the mean and standard deviation for Y= the profit he earns from this machine in a randomly selected week?​

Answer:

A function transformation takes whatever is the basic function f (x) and then "transforms" it (or "translates" it), which is a fancy way of saying that you change the formula a bit and thereby move the graph around. ... Moving the function down works the same way; f (x) – b is f (x) moved down b units.

Which graph shows the points (–3, 5) and (4, –3) plotted correctly?

Answers

Answer:

Step-by-step explanation:

This is clearly a linear relationship.  If Alex rented the movie for 0 days, he'd owe nothing.  If he paid $6 for a 3-day rental, the slope of this line would be m = rise / run = $6/(3 days) = $2/day, which is positive.

Then the equation for this graph is C(x) = ($2/day)x, where x is the number of days for which the movie is rented.

Using this formula, we find three particular points on the graph:

Answer:

d = 2[tex]\sqrt{7}[/tex]

Step-by-step explanation:

You want to solve for d by itself, so you must take the square root of both sides.

d = [tex]\sqrt{68}[/tex]

This can be simplified, since this square root has a perfect square inside. You take out the perfect square (which is 4) and end up with 2[tex]\sqrt{7}[/tex]

Pluto has been hard to measure from Earth because of its atmosphere. In 2007 Young, Young, and Buie measured Pluto as having a diameter of 2322 km. In 2017 new measurements were taken and Pluto is now believed to be 2376.6 km in diameter. Since the older measurement is now considered incorrect, what was the percent error of the 2007 measurement? [enter your answer as a percentage without the % sign] Round to two decimals.

Answers

Answer:

The percent error of the 2007 measurement is 2.30

Step-by-step explanation:

To determine the percent error of the 2007 measurement,

Percent error is given by

Percent error = [tex]\frac{|True value - Observed value| }{True value} \times 100%[/tex]%

Observed measurement in 2007 = 2322 km

True value (observed in 2017) = 2376.6 km

∴ Percent error = [tex]\frac{|2376.6 - 2322| }{2376.6} \times 100%[/tex]%

Percent error = [tex]\frac{54.6 }{2376.6} \times 100%[/tex]%

Percent error = 0.022974 × 100%

Percent error = 2.2974%

Percent error ≅ 2.30%

Since the answer is required to be entered without the % sign, then

Percent error = 2.30

Hence, the percent error of the 2007 measurement is 2.30.

Use slope to determine if lines PQ and RS are parallel,
perpendicular, or neither.
P(2, -1), Q(-3,-1), R(-11, 9), S(-7, 9)

Answers

Answer:

PQ and RS are parallel to each other

Step-by-step explanation:

Slope of two points (x1,y1) and (x2,y2) is given by

slope = (y2-y1)/(x2-x1)

for two lines to be parallel slope should be equalfor two lines to be perpendicular product of slope should be -1_______________________________________________

Lets find the slope of PQ and RS

for PQ P(2, -1), Q(-3,-1), R(-11, 9), S(-7, 9)

slope PQ = (-1 -(-1))/(-3 -2) = (-1 + 1)/5 = 0/5 = 0

Slope RS = (9-9)/(-7 - (-11) ) = 0/4 = 0

Since

slope PQ = slope RS = 0

Hence PQ and RS are parallel to each other
