the unscented candles burn faster at a rate of (1/3) inches/ hour
Step-by-step explanation:
scented candles:
(1/12) / (20/60) = 1/4 inches/ hour
unscented candles:
(1/6) / (30/ 60) = 1/3 inches/ hour

A vending machine that serves coffee pours a varying amount of liquid into a cup with varying mass. Assume
that the masses of the liquid and the cup are independent.
Here are summary statistics for the masses of the liquid and the cups:
Mean
Standard deviation
Liquid
HL
250 g
D = 20 g
Cup
HC = 150g
a = 10g
Let T = the total mass of a randomly selected cup filled with liquid from this machine.
Find the mean of T.
HT =
grams

Report a problem
Answer:400
Step-by-step explanation:
The mean of T is the expected weight of a selected cup filled with liquid
The mean of T is 400
The data on the table is given as:
Mean Standard Deviation
Liquid 250g 20g
Cup 150g 10g
Represent Liquid with L, and cup with C
To calculate the mean of T, we make use of the following formula for expected value
E(L + C)
Since L and C are independent random variables, then
[tex]E(L + C) = E(L) + E(C)[/tex]
Where E(L) and E(C) are the mean values of liquids and cups.
The equation becomes
[tex]E(L + C) = 250g + 150g[/tex]
[tex]E(L + C) = 400g[/tex]
Hence, the mean of T is 400

and g(x) =5/x-1
following options represents the asymptotes of the functions, f(x) and g(x) Select all that apply.
y= -1
y=0
x=-1
y=1
X= 2
Answer:
first and second
Step-by-step explanation:
asymptote of 1/x is y= 0 and x=0 (buut x=0 isn't on here)
asymptote of 5/x-1 is the same as 1/x-1, so y = -1 and x= 0

HURRY THIS IS MY LAST THING FOR THIS ASSIGNMENT. Maria is using a coordinate plane with the axes labeled only with integers. She says that the point (−0.5, 2) cannot be plotted because halves are not numbered on the x-axis. Write a note to Maria about her misunderstanding and explain how to plot the point.
Answer: You can have halves of points, Just because I have 0 units and 1 units doesn't mean that I can't put a point in the middle of the two. You could put a point in the middle of a unit for 0 - 1 it would be 0.5. You would place it in the middle of the unit

52% problems are pointless i.e. 48% are NOT pointless.
Recall that 1% = 1/100.
Therefore 48% = 48/100 = 12/25.
Let x be the number of problems that are not pointless.
x/175 = 12/25

A Porsche uses 2.5 litres of fuel every 2 kilometres it travels. How much fuel does it use if it travels 50 kilometres
Answer:
The Porsche uses 62.5 liters in 50 kilometers
Step-by-step explanation:
Amount of fuel Porsche uses = 2.5/2 liters/kilometer
= 1.25 L/Km
Distance to be travelled = 50 kilometer
Amount of fuel used in 50 km = 1.25 * 50
= 62.5 Liters
Therefore the Porsche uses 62.5 liters in 50 kilometers

HELP PLSSS Function g is a transformation x of f(x) = 2 ^ x Select all the true statements about the functions. (F-|F.2.4)
Answer:
its the second, not sure about 3
Step-by-step explanation:
2^x can never be negative
g is 2^x+4, which also can never be negative
neither have a y-intercept, so im not sure about three
but they have the same domain (-inf, inf), but not the same range, as g is always greater than 4, while f can be less than 4
and thus they don't have the same asymptote
both functions have an x-intercept: 1 for f(x), 5 for g(x)
so only the second choice is correct
Write the slope intercept form of the equation of the line through the given points

What is the minimum value of the objective function, C, with the given constraints?
C=2x+3y
A) 2x+3y≤24
B) 3x+y≤15
C) x≥2
D) y≥3
Given:
The objective function, [tex]C=2x+3y[/tex],
Constraints,
[tex]2x+3y\leq 24[/tex]
[tex]3x+y\leq 15[/tex]
[tex]x\geq 2[/tex]
[tex]y\geq 3[/tex]
To find:
The minimum value of the given objective function.
Solution:
We have,
Objective function, [tex]C=2x+3y[/tex] ....(i)
The related equations of given constraints are
[tex]2x+3y=24[/tex] ...(ii)
[tex]3x+y=15[/tex] ...(iii)
[tex]x=2[/tex], it is a vertical line parallel to y-axis and 2 units left from y-axis.
[tex]y=3[/tex], it is a horizontal line parallel to x-axis and 4 units above from y-axis.
Table of value for (i),
x : 0 12
y : 8 0
Table of value for (ii),
x : 0 5
y : 15 0
Plot these points on a coordinate plane and draw these 4 related lines.
The sign of inequality of [tex]2x+3y\leq 24[/tex] and [tex]3x+y\leq 15[/tex] is ≤, it means the related lines are solid lines and the shaded region lie below the related line.
For [tex]x\geq 2[/tex], left side of the line [tex]x=2[/tex] is shaded.
For [tex]y\geq 3[/tex], shaded region is above the line [tex]y=3[/tex].
From the below graph it is clear that the vertices of the feasible (common shaded region) are (2,3), (4,3), (3,6) and (2,6.667).
Points [tex]C=2x+3y[/tex]
(2,3) [tex]C=2(2)+3(3)=4+9=13[/tex] (Minimum)
(4,3) [tex]C=2(4)+3(3)=8+9=17[/tex]
(3,6) [tex]C=2(3)+3(6)=6+18=24[/tex]
(2,6.667) [tex]C=2(2)+3(6.667)=4+20=24[/tex]
Therefore, the objective function is minimum at point (2,3).
