The total amount that Mrs. Chauke paid for buying airtime using her bank's services sum up to R2.20. This question is about Analyzing Bank Statements.

Notice that on the 23rd of March and the 24th of March. On both occasions, she was charged R1.10 each.

Hence, to get the total amount she paid as charges for buying airtime, we say:

1.10 + 1.10  = R2.20

Step-by-step explanation:

[tex] \tan( \frac{x}{2} ) = \frac{ \sin(x) }{1 + \cos(x) } [/tex]

[tex] \tan( \frac{x}{2} ) = \frac{ \sqrt{1 - \cos(x) } }{ \sqrt{1 + \cos(x) } } [/tex]

So we have

[tex] \frac{ \sqrt{1 - \cos(x) } }{ \sqrt{1 + \cos(x) } } = \frac{ \sin(x) }{ \sqrt{1 + \cos(x) } } [/tex]

Next, we then rationalize the numerator so we get

[tex] \frac{ \sqrt{1 - \cos(x) } }{ \sqrt{1 + \cos(x) } } \frac{ \sqrt{1 + \cos(x) } }{1 + \cos(x) } = \frac{ \sin(x) }{ {1 + \cos(x) } } [/tex]

The denominator should be square root so to let you know .

So know we ahev

[tex] \frac{ \sqrt{1 - \cos {}^{2} (x) } }{1 + \cos(x) } = \frac{ \sin(x) }{1 + \cos(x) } [/tex]

[tex] \frac{ \sqrt{ \sin {}^{2} (x) } }{1 + \cos(x) } = \frac{ \sin(x) }{ {1 + \cos(x) } } [/tex]

[tex] \frac{ \sin(x) }{1 + \cos(x) } = \frac{ \sin(x) ) }{1 + \cos(x) } [/tex]

Answer:

A = 0.65

B = 3.304

C = 6.07

Step-by-step explanation:

You have to subtract to the final result the initial one and divide it for the number of segments. Then, for every segment you add the number you found, for example:

Value of a segment:

[tex] \frac{1 - 0.5}{10} = 0.05[/tex]

Value of A:

[tex]0.5 + 3 \times 0.05 = 0.65[/tex]

Answer:

Step-by-step explanation:

m<G = (1/2)[m(arc)LE - m(arc)HF]

m<G = (1/2)[150° - 40°)

m<G = 110°/2

m<G = 55°

Answer:

  the levels are 123.5 and 232.7 mg/mL

Step-by-step explanation:

The inverse normal function is used to find limit values from an area (probability).

Your calculator can show these values to you. (see attached)

The top 9% are above 232.7 mg/mL.

The bottom 9% are below 123.5 mg/mL.

__

A suitable calculator can evaluate the inverse normal function to find the x-value corresponding to some area, mean, and standard deviation. For the level that separates the bottom 9% from the rest of the area, we use an area value of 0.09. The mean and standard deviation values are those provided in the problem statement.

For the level that separates the top 9% from the rest of the area, we use an area value of 1 -0.09 = 0.91.

__

The second attachment shows an online calculator that can give the limits on the middle 0.91 -0.09 = 0.82 of the area under the probability curve.

_____

Additional comment

An app version of an approximation to a TI-Nspire calculator is shown in the first attachment. The invNorm function is found at the Distr key (2nd VARS).

For the top 9% we have to find the value x for which

P(X<x) = 0.91

Converted to the standard normal distribution this corresponds to

P(Z<(x-178.1)/40.7) = 0.91

Then: (x-178.1)/40.7 = 1.341

or x = 232.7

For the bottom 9% we have to find the value x for which

P(X<x) = 0.09

Converted to the standard normal distribution this corresponds to

P(Z<(x-178.1)/40.7) = 0.09

Then: (x-178.1)/40.7 = -1.341

or x = 123.5

So the 2 levels that separate the top 9% and the bottom 9% are 232.7 and 123.5.

227.1 m³

Explanation:

[tex]\sf \ formula \ of \ volume \ of \ cone \ \ : \dfrac{1}{3} \ \pi \ r^2 \ h[/tex]

[tex]\sf \hookrightarrow \dfrac{1}{3} \pi (4.4)^2 (11.2)[/tex]

[tex]\sf \hookrightarrow \dfrac{1}{3} \pi (216.832)[/tex]

[tex]\sf \hookrightarrow 72.3 \pi \ m^3[/tex]

[tex]\sf \hookrightarrow 227.066 \ m^3[/tex]

[tex]\sf \hookrightarrow 227.1 \ m^3[/tex]

Solution:

We know that:

[tex]Volume \ of \ cone = \pi r^{2} \frac{h}{3} \\\\ Height = 11.2 \ m\\\\ Diameter = 8.8[/tex]

Step-1: Find the radius of the cone.

[tex]Diameter = 2(Radius) \\\\ 8.8 \ m = 2(Radius) \\\\ \frac{8.8}{2} = \frac{2(Radius)}{2} \\\\ 4.4 \ m = Radius[/tex]

Step-2: Substitute the radius and the height in the formula.

[tex]Volume \ of \ cone = \pi r^{2} \frac{h}{3} \\\\ Volume \ of \ cone = (3.14)( 4.4^{2})( \frac{11.2}{3})\\\\ Volume\ of \ cone = (3.14)(19.36)( \frac{11.2}{3}) \\\\ Volume \ of \ cone = \frac{680.85}{3} = \bold{226.95 = 227 \ m^{3} \ (Rounded)}[/tex]

Thus, the volume of the cone is about 227 m³.

The is a probability of 15.87% that if you bake 34 muffins it would run out of today.

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ) / σ

Where x = raw score, μ = mean and σ = standard deviation.

Given that σ = 6, μ = 40, hence:

For x = 34:

z = (34 - 40)/6 = -1

P(z < -1) = 0.1587

Answer:

the answer for evaluate is number B

1 cube = 6 Faces

2 cubes = 10 Faces

7 cubes = 36 Faces

2÷7 = 3 × 10 = 30 + 6 = 36

The Answer is 36

Answer:

2 cubes = 10 faces

3 cubes = 14 faces

4 cubes = 18 faces

5 cubes = 22 faces

6 cubes = 26 faces

7 cubes = 30 faces

10 faces = 2 cubes

14 faces = 3 cubes

18 faces = 4 cubes

Step-by-step explanation:

We know that 1 cube shows 6 faces, and 2 cubes shows 10 faces. With 3 cubes, it shows 14 faces.

With this pattern, we can conclude that

f(x) = 2 + 4x

f(x) is a function for where f is the value of faces and x is the amount of cubes connected.

To find the amount of faces for the cubes used

f(2) = 2 + 4(2) = 2 + 8 = 10

f(3) = 2 + 4(3) = 2 + 12 = 14

f(4) = 2 + 4(4) = 2 + 16 = 18

f(5) = 2 + 4(5) = 2 + 20 = 22

f(6) = 2 + 4(6) = 2 + 24 = 26

f(7) = 2 + 4(7) = 2 + 28 = 30

For the amount of cubes used given the amount of faces

10 = 2 + 4x

-2   -2

8/4 = 4x/4

2 = x

x= 2

14 = 2 + 4x

-2    -2

12/4 = 4x/4

3 = x

x = 3

18 = 2 + 4x

-2   -2

16/4 = 4x/4

4 = x

x = 4

B. The equations create the same line

Step-by-step explanation:

A system of two linear equations have either 0, 1 or infinite solutions.

Since you have 2 solutions, there have to be infinitely many more. That means you have written the same line twice. The solution is B.

Alternatively, you can think that given two points, there is one and only one line that passes through both.
