Answer:

202

Step-by-step explanation:

First, we can find the conjugate of (-9 -11i)

Given a complex number a + bi, the conjugate would be a - bi.

So, the conjugate of -9 -11i is -9 + 11i.

Now, we multiply!

(-9-11i)(-9+11i)

This resembles the special product (a+b)(a-b) which multiplies out to a^2 - b^2

To apply this we subtract the square of the second number from the first.

(-9)^2 - (11i)^2

81 - 121i^2

i^2 is -1, so we can substitute it in:

81 + 121 = 202

median of seventh grade = 16.5

median of ninth grade = 16.5

Step-by-step explanation:

median = middle number, there are 18 numbers in total of each set. Since its even the middle number is kinda 16 and 17, but you can only choose one so the middle of 16 and 17 is 16.5

Answer:

-1 and 10

Step-by-step explanation:

Here we answer the question: "What two numbers multiply to -10 and add up to 9?"

The answer to your question is:

-1 and 10

Answer:

9

Step-by-step explanation:

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

(6, 9)

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

Answer:

6.25 meters

Step-by-step explanation:

25/4 = 6.25

Length of each cut piece is 6.25 m.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Given

A length of 25 meters cut the string in 4 pieces of equal length.

= [tex]\frac{25}{4}[/tex]

= 6.25

Answer: Because the graphs of the two equations overlap each other

Step-by-step explanation:

Every point on the first line also satisfies the second equation.

This is the same as equivalent fractions

Graphing these on a number line would only show one dot.

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:

We accept H₀  we don´t have enough evidence to support that more than 3 % of the packages are undeweight

Step-by-step explanation:

Sample size    n  = 1000

x ( defective packages found)  =  40

p  =  40 /1000     p  =  0,04    p  =  4 %     then  q = 0,96

np = 0,04 * 1000      and    nq  / 0.96 * 1000 both greater than 5

Then we can use the approximation of binomial distribution to normal distribution.

α is significance level       α =  0,05

From z- table we find  z(c)  for  α =  0,05      z(c)  =  1,64

Test Hypothesis

Null Hypothesis                          H₀             p  =  0,03

Alternative Hypothesis              Hₐ             p  >  0,03

We can see from alternative Hypothesis that the test is a one tail test to the right of the bell shape curve of the normal distribution

To calculate  z(c)  =   ( 0,04 -  0,03 ) / √ ( p*q)/n

z(c) = 0,01 * 31,62 / √ 0,04*0,96

z(c) = 0,3162 / 0,1959

z(c) = 1,6140      z(c) ≈ 1,61

Comparing  z(s)   and  z(c)

z(c) >  z(s)     1.64  > 1.61

Then z(s) is in the acceptance region for H₀    we accept H₀

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:

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:

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))

Additional comment

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.
