Answer:

The equation modeling the path of the bird in vertex form is [tex]y=2(x-2)^2+2[/tex]

Step-by-step explanation:

General vertex form equation: [tex]f(x) = a(x-h)^2 + k[/tex]

where (h,k) is the vertex

The flight path of a bird can be represented by this equation: [tex]y = 2x^2 - 8x + 10[/tex]

To convert the equation in vertex form

Completing the square :

[tex]y = 2(x^2 - 4x + 5)\\y = 2(x^2 - 4x + 5 +(2)^2-(2)^2)\\y = 2(x^2 - 4x + 5 +(2)^2-4)\\y = 2((x-2)^2-4+5)\\y = 2((x-2)^2+1)\\y=2(x-2)^2+2[/tex]

Where:

(h,k)=(2,2)

a=2

Hence the equation modeling the path of the bird in vertex form is [tex]y=2(x-2)^2+2[/tex]

 [tex]E(Z) =  202 [/tex]  

b

[tex]E(Z) = 198[/tex]

c

[tex]E(Z) = -140  [/tex]

Step-by-step explanation:

From the question we are told that

   The mean of X  is [tex] E(X)  =  20[/tex]

   The standard deviation of X is  [tex]s_1 = 5[/tex]

   The mean of Y  is [tex]\= y  =  40[/tex]

    The standard deviation of Y is  [tex]s_2 = 10[/tex]

Considering question a  

Generally the mean of   Z = 2 + 10X. is mathematically  represented

    [tex]E(Z) = E[2 + 10X ][/tex]

=> [tex]E(Z) =  2 +  10 E(X)[/tex]

=>  [tex]E(Z) =  2 +  10 * 20 [/tex]        

=>  [tex]E(Z) =  202 [/tex]          

Considering question b

Generally the mean of   Z = 10X - 2.. is mathematically  represented  

        [tex]E(Z) = E[10X -2 ][/tex]

   => [tex]E(Z) = 10E(X) - 2[/tex]

  =>  [tex]E(Z) = 10* 20  - 2[/tex]

  =>  [tex]E(Z) = 200  - 2[/tex]

 =>  [tex]E(Z) = 198[/tex]

Considering question c

Generally the mean of   -3X - 2Y is mathematically  represented

     [tex]E(Z) = E[-3X -2Y ][/tex]

     [tex]E(Z) = -3 E(X) -2E(Y) [/tex]

=>   [tex]E(Z) = -3 * 20 -2* 40 [/tex]

=> [tex]E(Z) = -140  [/tex]

if the next number is above or it is 5, then u round up

Answer:

66°

Step-by-step explanation:

[tex]\because \overrightarrow{QS} \: bisects\: \angle RQP\\\\

\therefore m\angle RQS = m\angle SQP\\\\

\therefore 2x + 10 = 3x - 18\\\\

\therefore 18 + 10 = 3x - 2x\\\\

\therefore 28 = x\\\\

\therefore x = 28\\\\

m\angle RQS = (2x + 10)\degree \\\\

m\angle RQS = (2\times 28+ 10)\degree \\\\

m\angle RQS = (56+ 10)\degree \\\\

\huge \purple {\boxed {m\angle RQS =66\degree}} \\\\

for making the statement true then find any decimal that when added won't give an answer greater than one.

eg, 0.5 + 0.2= 0.7 this makes the statement a+b<1 correct.

to make the statement false, add two decimals that'll gv answer greater fhan one.

eg, 0.8 + 0.3= 1.1, which makes the statement a+b<1 incorrect/ false

Complete Question

The worldwide market share for a web browser was 20.5​% in a recent month. Suppose that a sample of 200 random students at a certain university finds that 50 use the browser.

At the 0.05 level of​ significance, is there evidence that the market share for the web browser at the university is greater than the worldwide market share of 20.5​%?

Answer:

The decision rule is

Fail to reject the null hypothesis

The conclusion is

There is no sufficient evidence to show that the market share for the web browser at the university is greater than the worldwide market share of  20.5 ​%?

Step-by-step explanation:

From the question we are told that

          The population proportion is  [tex]p = 0.205[/tex]

          The sample size is  n  =  200

          The number that uses the browser is  k =  50

          The level of significance is  [tex]\alpha = 0.05[/tex]

Generally the sample proportion is mathematically represented as

       [tex]\^ p = \frac{50}{200}[/tex]

=>    [tex]\^ p = 0.250[/tex]

The null hypothesis is  [tex]H_o : p = 0.205[/tex]

The  alternative hypothesis  is  [tex]H_a : p > 0.205[/tex]

Generally the test statistics is mathematically represented as

          [tex]z = \frac{ \^ p - p }{ \sqrt{ \frac{ p (1 - p )}{ n} } }[/tex]

=>       [tex]z = \frac{ 0.250 - 0.205 }{ \sqrt{ \frac{ 0.205 (1 - 0.205 )}{ 200} } }[/tex]

=>       [tex]z = 1.5764[/tex]

Generally the area under  [tex]z = 1.5764[/tex]  to the right is  

     [tex]p-value = P( Z > 1.5764 ) = 0.057467[/tex]

From the value we obtained we can see that the [tex]p-value > \alpha[/tex] hence

 The decision rule is

Fail to reject the null hypothesis

   The conclusion is

There is no sufficient evidence to show that the market share for the web browser at the university is greater than the worldwide market share of 20.5 ​%?

1. Rational Algebraic Expression

2. 0

3. See explanation

Step-by-step explanation:

Solving (1):

From the list of given options, Option C. Rational Algebraic Expression answers the question.

And it is always of the form P/Q where P and Q are polynomials

Take for instance

P = x² - x + 2 and Q = x² + 2x - 4

P/Q = (x² - x + 2)/(x² + 2x - 4)

The above expression is a perfect example of a Rational Algebraic Expression

Solving (2): The denominator of a rational algebraic expression must not equal 0

Hence, option A answers the question

Solving (3): The options are missing.

However, a perfect example has been sighted on (1) above

Answer:

10,000 universes with the smaller number of atoms would fit inside the larger universe

Step-by-step explanation:

The correct question is as follows;

Physicists estimate that there are between 10^78 and 10^82 atoms in the universe. How do these two numbers compare with one another? If the larger number is right, how many universes with the smaller number of atoms would fit inside the larger universe?

Solution

To find the amount of the smaller number of atoms that will fit into the larger, we simply divide

Thus, we have;

10^82/10^78 = 10^4 = 10,000

Estimates are used to give the approximated value of a quantity.

10000 of the smaller universe will fit in the larger universe.

The number of atoms is:

[tex]\mathbf{n_1 = 10^{78}}[/tex]

[tex]\mathbf{n_2 = 10^{82}}[/tex]

(a) The larger universe

By comparison,

[tex]\mathbf{10^{82} > 10^{78}}[/tex]

This means that: the atoms in the second universe are larger than the number of atoms in the first.

(b) The number of small universe in the large universe

This is calculated by dividing the number of atoms in the large universe by the small universe

So, we have:

[tex]\mathbf{n = \frac{n_2}{n_1}}[/tex]

[tex]\mathbf{n = \frac{10^{82} }{ 10^{78}}}[/tex]

Apply law of logarithm

[tex]\mathbf{n = 10^{82 - 78} }[/tex]

[tex]\mathbf{n = 10^{4} }[/tex]

[tex]\mathbf{n = 10000 }[/tex]

Hence, 10000 of the smaller universe will fit in the larger universe.
