Answer:

1/12πx³

Step-by-step explanation:

Given that :

Base diameter = x

Height, (h) = x

Volume of a cone (V) :

1/3 πr²h

Where r = radius = diameter / 2 = x/2

Hence,

V = 1/3 * π * (x/2)² * x

V = 1/3 * π * x²/4 * x

V = 1/12 * π * x³

V = 1/12πx³

Answer:

1/2

Step-by-step explanation:

Step one:

given data

sample space

1 blue slice,

2 red slices, and

3 yellow slices

sample size= 1+2+3= 6

Required:

The probability that the dial stops on a blue or red slice

1. The probability that the dial stops on a blue = 1/6

2. The probability that the dial stops on a red= 2/6= 1/3

Hence The probability that the dial stops on a blue or red= 1/6+1/3

= 1+2/6

=3/6

=1/2

Answer:

wait hold on how much money does she have in total?

Step-by-step explanation:

Answer:

20 < x < 50

Step-by-step explanation:

The least she will buy is 4, so multiply that by 5 to get 20.

The most she will buy is 10, so multiply that by 5 to get 50.

So:

20 < x <50

Answer: 756: 1764

756 girls and 1,764 boys

Step-by-step explanation:

Girls to boys- 3:7

Total Students: 2,520

Using the information given, you will create an equation.

3x + 7x = 2,520

10x = 2,520

X = 252

Now you plug-in 252 for x in your ratio

X is the the number of people

3(252) : 7(252)

756: 1764

Now when you add these numbers, you get 2,520 which is the total number of students in all. This proves your answer to be correct.

Hope this helps!

The number of girls were in the class is 756 and the number of boys were in the class is 1764.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that, the ratio of the number of girls to the number of boys was 3 to 7.

2,520 students were present

Now, 3+7 =10

Number of girls =3/10 ×2,520

= 756

So, the number of boys =2520-756

= 1764

Therefore, the number of girls were in the class is 756 and the number of boys were in the class is 1764.

9514 1404 393

Answer:

  29.4°

Step-by-step explanation:

The equation can be rearranged to give C directly.

  C = arccos((a^2 +b^2 -c^2)/(2ab))

  C = arccos((90^2 +55^2 -50^2)/(2·90·55))

  C = arccos(8625/9900) ≈ 29.4002°

  C ≈ 29.4°

9514 1404 393

Answer:

  a.  10

  b.  5

  c.  3 with 1/4 pound left over

Step-by-step explanation:

You can find the number of 1/4 pound bags by dividing 2 1/2 pounds by 1/4 pound. In decimal, this is obvious:

  2.5/0.25 = 10

Using fractions, it is ...

  (2 1/2)/(1/4) = (5/2)/(1/4) = (10/4)/(1/4) = 10/1 = 10

__

a) Tim can make 10 1/4-pound bags from 2 1/2 pounds.

__

b) It is worthwhile to note that a 1/2-pound bag is equivalent to two 1/4-pound bags. So, the number of 1/2-pound bags will be 10/2 = 5.

Tim can make 5 1/2-pound bags from 2 1/2 pounds.

__

c) It is worthwhile to note that a 3/4-pound bag is equivalent to three 1/4-pound bags. So, the number of 3/4-pound bags will be 10/3 = 3 1/3.

Tim can make 3 3/4-pound bags from 2 1/2 pounds, with 1/4 pound left over.

Step-by-step explanation:

Since we start with 10,080 gallons after 0 minutes pass, we see the next point. Luckily, we are given an exact point of a number between 10,080 and 8640. The difference of those two numbers is 1440, and divide that by 2 to get 720. So we drain 720 per hour. HOWEVER, it says "minutes", so we divide 720 by 60 (hour -> minutes) to get 12.

*The reason I divided by 2 was to get the number of gallons after 1 hour passes*

[tex] \frac{c + d}{2} = \frac{c + d}{2} [/tex]

The required average of the two numbers c and d is a = [c + d] / 2.

To determine the average an of two numbers c and d.

The average of the values is the ratio of the total sum of values to the number of values.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Since, from the above definition,

Average = sum of the number / total number
We have c and d, two numbers

Now sum = c + d
Total number  = 2
Average = [ c + d ] / 2

Thus, the required average of the two numbers c and d is a = [c + d] / 2.

Explanation:

General information

All of these questions have to do with various translations of the square root function. The first problem deals with the basic function. Other problems translate the graph in various ways.

The basic square root function has its vertex at (0, 0) and is defined for x-values (domain) that are 0 or positive. The resulting y-values (range) are also zero or positive.

The basic function intercepts the x- and y-axes only at the point (0, 0), so both intercepts are 0. Unless the function is reflected vertically or horizontally, its minimum will be at the left end of any interval, and its maximum will be at the right end.

The transformation of a function g(x) to f(x) = g(x -a) +b causes it to be translated 'a' units to the right and 'b' units up. For the functions here, that means the vertex is translated from (0, 0) to (a, b). For the functions here, the vertex values are the limits of the domain and range, so those will be altered accordingly.

Problems

1.

a) The graph is shown in the attachment as f1 (orange).

b) vertex: (0, 0); domain: [0, ∞); range: [0, ∞)

c) x-intercept: 0; y-intercept: 0

d) On the interval [1, 4], the minimum is √1 = 1, and the maximum is √4 = 2.

__

2.

a) The graph is shown in the attachment as f2 (green). The basic function is translated left 1 and down 2.

b) vertex: (-1, -2); domain: [-1, ∞); range: [-2, ∞)

c) x-intercept: 3; y-intercept: -1 (read from the graph)

d) On the interval, [0.5, 5], the minimum is √1.5 -2 ≈ -0.78; the maximum is √6 -2 ≈ 0.45. Min and max values are shown in the table in the second attachment.

__

3.

a) The graph is shown in the attachment as f3 (purple). The basic function is translated up 3.

b) vertex: (0, 3); domain: [0, ∞); range: [3, ∞)

c) x-intercept: (none); y-intercept: 3 (the vertex)

d) On the interval, [2, 4], the minimum is √2 +3 ≈ 4.41; the maximum is √4 +3 ≈ 5. Min and max values are shown in the table in the third attachment.

__

4.

a) The graph is shown in the attachment as f4 (red). The leading multiplier of -2 causes the graph to be reflected over the x-axis and vertically expanded by a factor of 2 before being translated right 2 and up 3.

b) vertex: (2, 3); domain: [2, ∞); range: (-∞, 3]. Note the range is all y-values less than or equal to 3 because of the vertical reflection.

c) x-intercept: 4.25; y-intercept: (none). The x-intercept is found by solving ...

  0 = -2√(x -2) +3

  (-3/-2)² = x-2

  2 +2.25 = x = 4.25

d) On the interval, [4, 7], the minimum is -2√(7 -2)+3 = 3-2√5 ≈ -1.47; the maximum is -2√(4-2)+3 = 3-2√2 ≈ 0.17. Min and max values are shown in the table in the second attachment.

Answer:

The difference is significative we reject H₀

Step-by-step explanation:

Normal Distribution

Population mean            X₁    =  150

Population standard deviation       σ  =  25

Sample size        n   =  125

Sample mean     X₂   =  158

1.-CI =  95 %   significance level    α  =  5%    α = 0,05

From z-table α = 0,05    z(c)  =   1,64    ( the test is one-tail test to the right)

2.-Hypothesis Test

Null Hypothesis                                    H₀        X₂  =  X₁

Alternative Hypothesis                        Hₐ        X₂  >  X₁

3.-To compute z(s)

z(s)  =  ( X₂  -  X₁ ) / σ/√n

z(s)  =    8 * 11,14 /25

z(s)  =  89,12/25

z(s)  = 3,56

4.- Comparing  z(s)  and z(c)

z(s)  > z(c)

Then z(s) is in the rejection region we reject H₀

Sub a = 13 into 2a²-2a-15 =  2(13²)  - 2(13) - 15  =  338 - 26 - 15 = 297
