This question is incomplete, the complete question is;

In a survey, 55% of the voters support a particular referendum. If 40 voters are chosen at random,

find the mean and variance for the number of voters who support the referendum.

Answer:

a) The Mean is 22

b) Variance is 9.9

Step-by-step explanation:

Given that;

55% of the voters support a particular referendum p = 0.55

q = 1 - p = 1 - 0.55 = 0.45

sample size n = 40

a)

Mean = sample size n × p

Mean = 40 × 0.55

Mean = 22

Therefore the Mean is 22

b)

Variance = n × p × q

so we substitute

Variance = 40 × 0.55 × 0.45

Variance = 9.9

Therefore the Variance is 9.9

Answer:

1/6 tan(11 π) = 0

Alternate representations:

1/6 tan(11 π) = -1/6 cot((21 π)/2)

1/6 tan(11 π) = -1/6 cot((23 π)/2)

1/6 tan(11 π) = 1/(6 cot(11 π))

From here on, it's just a matter of condensing down the numbers. Very straightforward, and easy points on tests and quizzes. You can do this in your head if you want, or you can just do it on your calculator (which is probably the best way to go as it's faster and more accurate).

Once again, these types of evaluation problems are very straightforward, and are usually always easy points on tests and quizzes if you have an inkling of an idea of what the concept is about. Again, if you have a calculator with all the appropriate functions, that makes it even easier.

Speaking from experience, when you work with rational (fraction) polynomials on paper, it often tends to take up a bit of space and get messy. Therefore, I'd suggest you tried solving one equation at a time if you have the same issue.

Also, sometimes you may come across values that you don't want to type again in your calculator (like non-recurring decimals). For these, use the store function on your calculator to get maximum accuracy. With TI-84 and 83s, you can save values as letters (X, Y, etc.). Hence, you can just write out your equation using these, and hence significantly reduce the risk of typing the number wrong, while saving yourself some time.

The expression for the total amount she charged can be represented as A = 20n.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

For example 2x = 54

An expression is a mathematical proof of the equality of two mathematical expressions.

Given that,

She will charge $20 for every lawn

Number of lawns she mows = n

Total charge let's represent by A

Then,

A = 20n will be the correct expression.

Hence "The expression for the total amount she charged can be represented as A = 20n".

Answer: Number of winning tickets =7 and Number of losing tickets = 28 .

Step-by-step explanation:

Given: Total tickets = 35

The ratio of winning tickets to losing tickets = 1:4

Number of winning tickets = [tex]\dfrac{1}{1+4}\times35[/tex]

[tex]=\dfrac{1}{5}\times35\\\\=7[/tex]

Number of losing tickets = [tex]\dfrac{4}{5}\times35[/tex]

[tex]=4\times7=28[/tex]

Hence, Number of winning tickets =7 and Number of losing tickets = 28 .

Answer:

7 wining tickets and 28 losing tickets

Answer:

The graph of g(x) has a lesser y intercept

Step-by-step explanation:

Given

f(x) = 100(-x + 4)

Required

Determine the relationship between f(x) and g(x)

First, we need to get the equation of g(x).

From the question, we have that:

Initial Value = 360

Rate = -90 yearly

[It is negative because the rate shows decrement]

Hence, the equation of g(x) is:

g(x) = Initial Value + Rate * x

Where x represents number of years

g(x) = 360 + (-90 * x)

g(x) = 360 - 90x

g(x) = -90x + 360

Recall that

f(x) = 100(-x + 4)

f(x) = -100x + 400

To solve y intercept, we set x = 0.

f(0) = -100 * 0 + 400 = 0 + 400 = 400

g(0) = -90 * 0 + 360 = 0 + 360 = 360

By comparison, the graph of g(x) has a lesser y intercept

To solve x intercept, we set y = 0

For f(x)

0 = -100x + 400

100x = 400

x = 4

For g(x)

0 = -90x + 360

90x = 360

x = 4

By comparison, they have the same x intercepts.

From the list of given options, option A answers the question.

Answer:

The answer should be B

Answer:

-500

Step-by-step explanation:

Given sequence;

    97, 94, 91 ......

Unknown;

The 200th term of the sequence;

Solution:

Since we were given an arithmetic progression, we need to first find the common difference;

 Common difference  = second term - first term

                                     = 94 - 97  

                                     = -3

To find the 200th term, we use the expression below;

     Sn  = a + (n-1)d

   a is the first term

    n is the nth term

   d is the common difference

 S₂₀₀ = 97 + (200 - 1 ) x -3 = -500

Answer:

B: 2 32/48

Step-by-step explanation:

Common denominator: 24

68 x 3 = 204

8 x 3 = 24

35 x 4 = 140

6 x 4 = 24

Set-up:

204/24 - 140/24
