Your office is moving into a new space and you have to decide if you want electric heat or natural gas. you have determined that it will take about 4000 kwh per month to heat the space with electricity and currently your electric company charges $0.075 per kwh. the natural gas provider currently charges $1.85 per therm.the conversions you will need are:1 kwh = 3,413 btu; 100,000 btu = 1 therm.
One number is 4 less than 3 times a second number. If 3 more than two times the first number is decreased by two times the second, the result is 11. What are both numbers?
Which expression correctly represents “three less than the product of a number and two, increased by five”?

Answer:
The expression that is equivalent to the given expression is:
5x+60
Step-by-step explanation:
It is given that:
if you add 12 marshmallows to each of 5 bags of marshmallows, and each bag started with the same number of marshmallows.
so, let x be the initial number of marshmallows in each bag and now 12 are added to each bag this means that the number of marshmallows in each bag is:
x+12
Hence, total number of marshmallows in 5 bags is:
5(x+12)=5×x+5×12
5(x+12)=5x+60
Hence, the answer is:
5x+60

The answer of the question is 60.
B.He can pick players at random and analyze their playing stats without calculating means.
C.He can analyze the two groups by calculating the means and the difference of the means.
D.He can pick the players he wants to analyze based on the best stats.
Answers
Answer:
The answer is option A.
Step-by-step explanation:
How can the coach test the means to be sure the results are not likely to happen by chance?
A.He can re randomize the results by separating the two groups randomly, then calculate the means and the difference of the means. (This is because, in statistical data, it cannot happen by chance. It has to be a valid occurrence, nothing by chance.)
Answer:
A.He can rerandomize the results by separating the two groups randomly, then calculate the means and the difference of the means.
Step-by-step explanation:
He can randomize again the players that are receiving the bar and those who are not, and then after that he can see if the results from the previous experiment were accurate or if they happened just by chance. In this way he can make sure that if the results with this two new groups after randomizing are the same that the bar is actually improving the players an edge on performance.

Answer:
b
Step-by-step explanation:
given that c is the midpoint of segment ab and ab = 20
Then ac is one half of ab
ac = × 20 = 10
Final answer:
In Geometry, a midpoint divides a line segment into two equal parts. So, if C is the midpoint of line segment AB with a total length of 20 units, the length of segment AC is 10 units.
Explanation:
The subject of this question is in the area of Geometry, specifically, it's about understanding the concept of a midpoint in a line segment. In a line segment AB, if C is the midpoint, it divides the line segment AB into two equal parts. So, if the total length of AB is 20 units, then the lengths of AC (from A to C) and BC (from B to C) are both equal to half of the total length. Hence, the length of segment AC is
10 units
. This is the concept of a midpoint which divides any given segment into two halves.

a. 226m³
EXPLANATION
The volume of a cylinder is calculated using the formula:
where r is the radius and h=8m is the height of the cylinder.
The radius is half of the diameter.
This means that:
We plug in the values into the formula to get:
To the nearest cubic meters, the volume is 226 m³.

Answers
Answer:
11. This is an input problem. The hours needed to produce one unit represent the input required to produce each unit of ukuleles and surfboards.
12. Jack's opportunity cost of producing 1 ukulele is 3 surfboards. This means that if Jack decides to produce 1 ukulele, he foregoes the opportunity to produce 3 surfboards.
13. Jack's opportunity cost of producing 1 surfboard is 0.3 ukuleles. This means that if Jack decides to produce 1 surfboard, he foregoes the opportunity to produce 0.3 ukuleles.
14. Jill's opportunity cost of producing 1 ukulele is 5 surfboards. This means that if Jill decides to produce 1 ukulele, she foregoes the opportunity to produce 5 surfboards.
15. Jill's opportunity cost of producing 1 surfboard is 0.2 ukuleles. This means that if Jill decides to produce 1 surfboard, she foregoes the opportunity to produce 0.2 ukuleles.
16. Jill has the absolute advantage in producing ukuleles because she can produce 1 ukulele in 25 hours, while Jack requires 12 hours to produce 1 ukulele.
17. Jack has the absolute advantage in producing surfboards because he can produce 1 surfboard in 4 hours, while Jill requires 5 hours to produce 1 surfboard.
18. Jill has the comparative advantage in producing ukuleles because her opportunity cost of producing 1 ukulele (5 surfboards) is lower than Jack's opportunity cost of producing 1 ukulele (3 surfboards).
19. Jack has the comparative advantage in producing surfboards because his opportunity cost of producing 1 surfboard (0.3 ukuleles) is lower than Jill's opportunity cost of producing 1 surfboard (0.2 ukuleles).
