Answer:
Final answer is [tex]c=12t[/tex].
Step-by-step explanation:
Given that the amount c of energy you burn and the time t you spend exercising, if you burn calories at a rate of 12 Cal/min.
Now we need to write a function rule for the relationship between c and t.
given that cal/min=12
or [tex]cal/min=12/1[/tex]
or [tex]c/t=12[/tex]
or [tex]c=12t[/tex]
Hence final answer is [tex]c=12t[/tex].
Find the median of the following data set 6,2,59,12,11,9,9,54,54,46,2,32,43,11
By arranging the numbers in ascending order we get,
2, 2, 6, 9, 9, 11, 11, 12, 32, 43, 46, 54, 54, 59
The 2 middle numbers are:
11, 12
To find the median we have to add them and divide them by 2
So, (11+12)÷2
23÷2
11.5
For this case we have by definition that the median of a set of numbers is the average number in the set, after the numbers have been arranged from the lowest to the highest. If there is an even number of data, the median is the average of the two average numbers. So:
We order the numbers from least to greatest:
2,2,6,9,9,11,11,12,32,43,46,54,54,59
We have 14 numbers:
[tex]\frac {11 + 12} {2} = \frac {23} {2} = 11.5[/tex]
Answer:

x –3 –2 –1 0 1
y –17 –14 –11 –8 –5
y = –3x – 8
y = 1/3x – 8
y = 3x – 8
y = 1/3x + 8
Answer: The answer is y=3x-8
Step-by-step explanation: All you have to do is plug in the x values and see what you get for y. For example: when you plug in -3 for x. y=3(-3)-8 than you multiply the -3 by 3 and that give you y=-9-8 which equals y=-17 so that shows you the equation works.
plugging in -2 for x
y=3(-2)-8
y=-6-8
y=-14
I hope this helps!!!
Answer:
y = 3x -8
Step-by-step explanation:
You can try a point in the function rules and see if it works. The first (x, y) pair is suitable for finding the right answer:
y = -3(-3) -8 = -1 ≠ -17 . . . . eliminates the first choice
y = 1/3(-3) -8 = -9 ≠ -17 . . . . eliminates the second choice
y = 3(-3) -8 = -17 . . . . . the third choice is viable
y = 1/3(-3) +8 = 7 ≠ -17 . . . . eliminates the last choice
__
Only the third choice is a possible solution. Checking other points from the table verifies this as the correct one.

Step-by-step explanation:
By definition, the surface area of a cylinder is given by the following formula:
[tex]A = 2\pi r h + 2\pi r ^ 2[/tex]
Where r is the radius and h is the height.
In this case, we have to:

Step-by-step explanation:
Let f(x)=x2+14x+36 .
What is the vertex form of f(x)?
What is the minimum value of f(x)?
Enter your answers in the boxes.
Answer:
see explanation
Step-by-step explanation:
The vertex form of f(x) is
f(x) = (x - h)² + k
where (h, k) are the coordinates of the vertex
To obtain this form use the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² + 14x
f(x) = x² + 2(7)x + 49 - 49 + 36
= (x + 7)² - 13
The minimum value of f(x) is the y- coordinate of the vertex
vertex = (- 7, - 13), that is minimum value = - 13
The vertex form of the function f(x)=x²+14x+36 is (x + 7)² - 13, with the vertex at (-7, -13). The minimum value of f(x) is -13.
Explanation:To convert the function f(x) = x²+ 14x + 36 into vertex form, we need to complete the square. First, factor out the coefficient of the x² term if it is not 1 (in this case it is 1, so no factoring is necessary), and then group the x terms.
f(x) = (x²+ 14x) + 36
Add and subtract the square of half of the coefficient in front of x within the parenthesis to complete the square:
f(x) = (x² + 14x + 49) - 49 + 36
Simplify:
f(x) = (x + 7)² - 13
Now the function is in vertex form, which is y = a(x - h)² + k, where (h, k) is the vertex. Here, the vertex is at (-7, -13).
The minimum value of the function f(x) occurs at the vertex since the coefficient of the x² term is positive, indicating a parabolic shape opening upwards. Therefore, the minimum value of f(x) is -13.

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). A six-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. In the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. The experimental probability of rolling a 3 is %, which is approximately % more than its theoretical probability. (Round off your answers to the nearest integer.)
Answer:
The experimental probability of getting a 3 on a die is 30% which is approximately 13% more than its theoretical probability (17%).
Step-by-step explanation:
Theoretical probability of number 3 on a die:
Total no. of possibilities = 6
Probability of getting a 3 on a die each time it is rolled = 1/6
= 0.16667
= 17%
Experimental probability of number 3 on a die:
Total no. of rounds = 4
Rolls each round = 20
no. of 3s in round 1 = 6
no. of 3s in round 2 = 6
no. of 3s in round 3 = 5
no. of 3s in round 4 = 7
Total rolls = 20*4 = 80
no. of times 3 comes up = 6+6+5+7 = 24
Experimental probability of getting a 3 on a die
each time it is rolled = no. of 3s/total rolls
= 24/80
= 0.3
= 30%
Difference = 30% - 17% = 13%
Experimental probability of getting a 3 on a die is 30% which is approximately 13% more than its theoretical probability (17%).
Answer:
The experimental probability of rolling a 3 is 30 %, which is approximately 13 % more than its theoretical probability.

Please help! I'm am not that great at graphing like this...
Thanks a bunch! :)
Answer:
Step-by-step explanation:
If it's less than or greater than (<, >), then the circle is hollow.
If it's less than or equal to, or greater than or equal to (≤, ≥), then the circle is solid.
Less than points to the left, greater than points to the right.
Here we have less than (not equal to). So the circle is hollow, and the arrow points left. So the correct answer is the first one.
We can check our answer by picking a point and seeing if it's true. If we pick c=-6, is it true that -6 < -1? Yes.

Answer:
Fourth answer choice: y = x + 3
Step-by-step explanation:
Note that sides a and s are perpendicular to side r. Both sides a and s have positive slopes, so we can immediately eliminate answer choices 1 and 2.
If we extend side s up and to the left, it intersects the y-axis at (0, 3). Thus, the y-intercept is +3 and the desired equation is:
y = x + 3

equation?
The discriminant is negative
The discriminant is -3.
The discriminant is 0.
The discriminant is positive
Answer:
The discriminant is 0
Step-by-step explanation:
Since the graph of the quadratic equation has only one x-intercept, we can conclude that the quadratic has only one real root.
If a quadratic equation has only one real root, then the discriminant is 0
If x = -3 is the only x-intercept of the graph of a quadratic equation then the discriminant is 0

Step-by-step explanation:
The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y – 4 = (x – 8). What is the slope-intercept form of the equation for this line?
y = x – 12
y = x – 4
y = x + 2
y = x + 6
Answer:
y = x - 4
Step-by-step explanation:
Rewrite y – 4 = (x – 8) in slope-intercept form. To do this, solve the given equation for y:
y - 4 = x - 8 → y = 4 + x - 8, or y = x - 4
As the point-slope form is given, we will simplify it;
[tex]y-4=x-8[/tex]
By adding +4 on both the sides, we get:
⇒[tex]y=x-8+4[/tex]
⇒[tex]y=x-4[/tex]
The slope-intercept form of the equation for this line is y=x-4.
Hence, the correct answer is option (b).

B.
0.2525
C.
0.8125
D.
1.0000
Answer:
C. 0.8125
Step-by-step explanation:
The probability to sell 5 or more DVDs in a day is the complement of the probability of selling less than 5 DVDs in a day, since sales <5 DVDs + sales >= 5 DVDs = 100% of the sales.
So, we know what's the probability of selling less than 5 DVDs in a day is... it's 0.1875
So, to find the possibility of selling 5 or more DVDs in a day, we take 100% of the chances (1.0) and we subtract the probability of selling <5 DVDs in a day:
P = 1.0 - 0.1875 = 0.8125
C. 0.8125 is your answer.
A diver who has a mass of 68 kg climbs to a diving platform that is 7.5 m above the surface of a pool. How much gravitational potential energy does the diver have in relation to the pool’s surface? 510 J 1912 J 3825 J 4998 J
Answer:
option D
4998 J
Step-by-step explanation:
Given in the question that,
mass of the diver = 68 kg
distance of the diver from the surface of a pool = 7.5 m
The gravitational potential energy of an object is given by
GPE = m(g)(h)
here,
m is the mass of the diver
g is the acceleration due to gravity = 9.81m/s²
h is the height from the surface
Plug values in the formula to calculate GPE
GPE = 68(9.8)(7.5)
= 4998 J
Therefore, the gravitational potential energy of the diver with respect to the surface of the pool is 4998 J
Final answer:
The diver has 4986 Joules of gravitational potential energy in relation to the pool's surface, with the closest answer choice being 4998 J, assuming rounding differences. Hence, the answer is D.
Explanation:
To calculate the gravitational potential energy (GPE) of the diver in relation to the pool's surface, we can use the formula GPE = mgh, where m is the mass of the diver, g is the acceleration due to gravity (9.8 m/s2), and h is the height of the diving platform above the pool's surface.
Substituting the diver's mass (68 kg) and the height of the diving platform (7.5 m) into the equation, we get:
GPE = (68 kg) times (9.8 m/s2) times (7.5 m)
GPE = 4986 Joules
Therefore, the diver has 4986 Joules of gravitational potential energy in relation to the pool's surface. Since this value isn't exactly one of the choices, it's likely due to rounding differences, and the closest provided option is 4998 J, which we could assume is the intended answer.

Answer:
22.5 lbs
Step-by-step explanation:
First you find the cubic feet. That is the volume of the object which is length*width*height.
In your example, they are using inches. So you have to convert all units to feet. That would be 0.5 inches, 0.5 inches, and 5/3 inches. The volume would be 0.5*0.5*5/3 which is about 5/12 cubic feet
You then take that 5/12 cubic feet and multiply it by the 54 lbs/cubic foot. The answer would be 22.5 lbs
