bro what does "log 2" mean in math

Answer:

D

Step-by-step explanation:

When you are raising something to a fractional power, you are raising it to the power of the numerator and finding the root denoted by the denominator. The explanation above is kinda confusing, so here is an example:

x^(3/5)

This would be written as:

[tex]\sqrt[5]{x^3}[/tex]

Now for the actual problem. Since the numerator is 4, we start by raising x to the 4th power, x^4.

Because the denominator is 5, we find the 5th root:

[tex]\sqrt[5]{x^4}[/tex]

This matches none of the answers shown, so the answer is none of the above or D.

Answer:

D

Step-by-step explanation:

The answer would be 5 square root x^4

[tex]\begin{array}{cccc}{} & {Samples} & {Positive} & {Negative} & {Contains\ Organic\ Matter} & {700} & {665} & {[35 ]} & {Does\ not\ contain\ organic\ matter} & {300} & {[60]} & {240} \ \end{array}[/tex]

[tex]\% Pr= 95\%[/tex]

Step-by-step explanation:

Given

[tex]\begin{array}{cccc}{} & {Samples} & {Positive} & {Negative} & {Contains\ Organic\ Matter} & {700} & {665} & {[\ ]} & {Does\ not\ contain\ organic\ matter} & {300} & {[\ ]} & {240} \ \end{array}[/tex]

Solving (a): Complete the table

The sum of each row must equal to the samples.

i.e.

[tex]Positive + Negative = Samples[/tex]

For the samples that contain organic matter, we have:

[tex]665 + Negative = 700[/tex]

Collect like terms

[tex]Negative = 700 - 665[/tex]

[tex]Negative = 35[/tex]

For the samples that do not contain organic matter, we have:

[tex]Positive + 240 = 300[/tex]

Collect like terms

[tex]Positive = 300 -240[/tex]

[tex]Positive = 60[/tex]

So, the complete table is:

[tex]\begin{array}{cccc}{} & {Samples} & {Positive} & {Negative} & {Contains\ Organic\ Matter} & {700} & {665} & {[35 ]} & {Does\ not\ contain\ organic\ matter} & {300} & {[60]} & {240} \ \end{array}[/tex]

Solving (b): Proportion of samples that are positive if the sample contains organic matter

From the table, we have:

[tex]Samples = 700[/tex]

[tex]Contains\ Organic\ Matter\ n\ Positive = 665[/tex]

So, the percentage is:

[tex]\%Pr = \frac{Contains\ Organic\ Matter\ n\ Positive}{Samples} * 100\%[/tex]

[tex]\% Pr= \frac{665}{700} * 100\%[/tex]

[tex]\% Pr= \frac{665* 100}{700} \%[/tex]

[tex]\% Pr= \frac{66500}{700} \%[/tex]

[tex]\% Pr= 95\%[/tex]

Answer:

10.5

Step-by-step explanation:

Given the data:

Age. l frequency

1-5. l 3

6-10. l 3

11-15. l 3

16-20. I 3

Mean :

Σfx / Σf

Obtain the midpoint (x) = (upper + lower boundary) / 2

Hence, midpoint x :

Age. l frequency | x

1-5. l 3 | 3

6-10. l 3 | 8

11-15. l 3 | 13

16-20. I 3 | 18

Σfx = (3*3) + (3*8) + (3*13) + (3*18) = 126

Σf = (3 + 3 + 3 + 3) = 12

Mean = Σfx / Σf = 126 / 12 = 10.5

Answer:

b = 7.56

C = 9.24

Step-by-step explanation:

Find the last angle of the triangle.

The sum of all the angles in a triangle is  

180 degrees.

A+

90+55=180

A=35

Then find c

The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

cos(B)=adj/hyp or Cos(55) = 5.3 / c

re write as

C = 5.3 / cos55

This gives you c = 9.24

Then use the Pythagorean theorem to find the unknown side.

[tex]a^{2} +b^{2} = c^{2} \\rewrite as\\ b^{2} = c^{2} - a^{2} \\b^{2} = 9.2^{2} - 5.3^{2} \\b^{2} = 57.29\\b = 7.56[/tex]

Answer:

The answer is "Option E".

Step-by-step explanation:

In order to find the contribution needed, we must use Chi-Square test statistics here.

Chi-square [tex]= \Sigma [\frac{(O -E)^2}{E}][/tex]

Here frequencies O are observed or frequencies E are expected.

Please find the calculation in the attached table.

Hence the contribution Chi-square is the highest for the vegetarian.

The value of its contribution to the appropriate test statistic the greatest is Vegetarian. The correct option is E.

It is a measure of the difference between the observed and expected value or frequency of the outcomes of a set of event variables.

The manager of a restaurant tracks the types of dinners that customers order from the menu correct amount of food is ordered from the supplier each week. Data from customer orders last weekly distribution.

Type of Dinner Beef, Chicken, Fish, Pork, and Vegetarian

Proportion 0.18 0.41 0.15 0.20 0.06

The manager believes that there might be a change in the distribution from last year to this year. A random sample of 200 orders was taken from all customer orders placed last week. The following table shows the results of the sample.

Type of Dinner Beef, Chicken, Fish, Pork, and Vegetarian

Frequency 32 86 34 30 18

The table is shown below.

The value of its contribution to the appropriate test statistic the greatest is Vegetarian. The correct option is E.

Answer:

a. R 2+ S 2= T 2

Step-by-step explanation:

Is this multiple choice? If not, then I will explain my answer.

I would say that it is R² + S² = T² because, the original pythagorean theorem equation is a² + b² = c².

They are put in an alphabetical order, a, b, c.

R goes first in the alphabet, then S and T. So, that's why I say it is:

R² + S² = T²

Answer: 60 + 13 sqrt 10

the top part adds up to 10 and the bottom part is 13

so you get a 7-3-2 sqrt 10 triangle to the left

the area of that is 3 sqrt 10

the area of the leftmost rectangle is 5 * 2sqrt 10 which is 10 sqrt 10

the area of the big vertical rectangle is 5*12 which is 60

so you add them up

60 + 13 sqrt 10

Answer:

Step-by-step explanation:

Area = height × side

Plug in 6 to x, since this is the x-value in the ordered pair.

[tex]3(6)+2y=36\\18+2y=36\\2y=18\\y=9[/tex]

Answer:

(6, 9)

Step-by-step explanation:

3x + 2y = 36

Substitute 6 into the equation to get the output.

3(6) + 2y = 36

Multiply 3 and 6.

18 + 2y = 36

Subtract 18 from both sides.

2y = 18

Divide both sides by 2.

y = 9

The ordered pair when x = 6 is

Answer:

Step-by-step explanation:

The law of sines tells you the ratio of sides is the same as the ratio of sines of their opposite angles.

This post has 2 kinds of problems.

1) 2 angles and the side between them are given.

2) 2 sides and the angle opposite the longest is given.

For the first type, you need to determine the missing angle (opposite the given side). That comes from the sum of angles of a triangle being 180°. Then you find the remaining sides using the ratio of sines.

For the second type, the angle opposite the shorter side is found using the ratio of sides to find the sine of that angle. Then the third side and third angle can be found using the ratio of sides to find the sine of the angle, and using the ratio of sines to find the missing side.

Straightforward, and tedious. For more than one, I like to use a spreadsheet to crunch the numbers.

_____

1) BC = 24.0

2) AC = 26.0

3) m∠B = 73.4°

4) m∠B = 30.0°

__

In the spreadsheet, the given values are in the first 3 columns. The 4th column is the first one calculated. As indicated above, the angle calculation for problems 1 and 2 uses the sum of angles relation. For problems 1 and 2, this is the angle opposite the given side. The "first side" is the side opposite the "first angle". c = b·sin(C)/sin(B), for example.

For problems 3 and 4, the first unknown angle is the one opposite the "short side", which is the shorter of the given sides. As it happens, this is the side that is asked for in the question. B = arcsin(c·sin(B)/sin(C))

In a spreadsheet, angles are presumed to be in radians for all of the trig functions. We use the DEGREES( ) and RADIANS( ) functions to convert as appropriate.
