Answer:

[tex]a_n = 9 - 2(n-1)[/tex]

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms is always the same, and is called common difference.

The nth term is given by the following equation:

[tex]a_n = a_1 + (n-1)d[/tex]

In which [tex]a_1[/tex] is the first term and d is the common difference.

First term is 9 common difference is -2

This means that [tex]a_1 = 9, d = -2[/tex]

So, the nth term is given by:

[tex]a_n = a_1 + (n-1)d[/tex]

[tex]a_n = 9 + (n-1)(-2)[/tex]

[tex]a_n = 9 - 2(n-1)[/tex]

Answer:

x = 47.2

Step-by-step explanation:

Since this is a right triangle, we can use  trig functions

cos theta = opp / hyp

cos x = 17/23

Taking the inverse cos of each side

cos ^-1 ( cos x) = cos ^-1 ( 17/25)

x =47.15635696

To the nearest tenth

x = 47.2

✍ Having as t₃ =10 and t₁₀ = -4.  We have to find the common ratio.

❑  If, in front of the sequence from 3 to 10, there are 7 numbers, that is, 7 terms, we have to find a pattern, what I used was this one.

[tex]\large {\text {$ \sf 7 \longrightarrow Number \: Terms $}}[/tex]

[tex]\large {\text {$ \sf x \longrightarrow rasion $}}[/tex]

          We see that in the calculation, the only number that fits is -2.

➤ Because if we stop to think about it, we have -2 of common ratio among these 7 terms is -14, so 10-14 = -4

So the hypothesis is correct!

➜ Being right as -2 and resuming the terms of 10, we have:

[tex]\huge {\boxed {\blue {\sf t_{10}, t_{11}, {\bf t_{12}} = \{ -4 , -6 , \bf -8 \} } }}[/tex]

So t₁₂ is equal to -8.

Answer:

Step 1: True

1. Approximately 2000 families are in the sample.

2. False.

3. 31.2 hours.

4. False.

Step-by-step explanation:

The 55th percentile is greater than or equal to 30 hours.

The median is of 31.2 hours, which means that the 50th percentile is of 31.2 hours. The 55th percentile is above the 50th percentile, and thus, the 55th percentile is greater than 31.2 hours, and thus, also greater than 30 hours, and the statement is true.

1: Approximately how many families are in the sample?

Twenty-four of the families in the sample turned on the television for 20 hours or less for the week. The 12th percentile of the data is 20 hours, and thus 24 is 12% of the sample size n. So

[tex]0.12n = 24[/tex]

[tex]n = \frac{24}{0.12}[/tex]

[tex]n = 2000[/tex]

Approximately 2000 families are in the sample.

2: Based on the given information, determine if the following statement is true or false. Approximately 200 families turned on their televisions for less than 35 hours.

The median, that is, the 50th percentile, is of 31.2 hours.

Thus, 35 hours is above the 50th percentile, which means that more than 1000 families(considerably more than 200) will have turned on their TVs for less than 35 hours, and this statement is false.

3: What is the value of the 50th percentile?

The median, which is of 31.2 hours.

4: Based on the given information, determine if the following statement is true or false.The first quartile is greater than or equal to 20 hours.

20 hours is the 12th percentile, which means that the first percentile is less than 20 hours, and this statement is false.

Answer:

45

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

Given the mean of 8 numbers is 41 , then

[tex]\frac{sum}{8}[/tex] = 41 ( multiply both sides by 8 )

sum of 8 numbers = 328

Given the mean of 2 numbers is 29 , then

[tex]\frac{sum}{2}[/tex] = 29 ( multiply both sides by 2 )

sum of 2 numbers = 58

The sum of the remaining 6 numbers = 328 - 58 = 270 , so

mean = [tex]\frac{270}{6}[/tex] = 45

The mean of the other 6 numbers = 45

Step-by-step explanation:

When a doctor analyzes the increase in systolic blood pressure caused by a certain chemo drug. The doctor would be more interested in studying the mean of the number of observed systolic blood pressures. As mean would give a better understanding of pressure since it involves the use of all observations. However, it is important to keep in mind that all the units should be considered for the average.

Answer:

the angle that is 110° and 30°

Step-by-step explanation:

The triangle is similar to triangle T is triangle III.

Thus, option (c) is correct.

In the given triangle,

Two angles are 110 and 40.

Using Angle sum property in given triangles as

Angle 1 + Angle 2 + Angle 3 = 180

110 + 40 + Angle 3= 180

150 + Angle 3= 180

Angle 3 = 180 - 150

Angle = 30

Thus, the angles are 110, 40 and 30.

Therefore, Triangle III is similar to triangle T.

Answer:

34

Step-by-step explanation:

The sum of the angles of a triangle is 180

26x+6 + 21x-1 +11x+1 = 180

Combine like terms

58x +6 = 180

Subtract 6 from each side

58x = 180-6

58x = 174

Divide by 58

58x/58 =174/58

x=3

Answer:

x=-1 or x=4

Step-by-step explanation:

First divide by 4 to get rid of the factor 4 at x², then you have:

x² - 3x - 4 = 0

to factor that, look for two numbers that when added, give -3, and when multiplied, give -4. This is guesswork but usually doable:

-4 + 1 = -3

-4 * 1 = -4

so -4 and +1 are our numbers.

The factorization is therefore: (x - 4)(x + 1) = 0, and the solutions are

x-4 = 0 or x+1 = 0, so x=4 or x=-1

The rational equations after division is

a) A = ( 5x³ - 15x )

b) B = - ( 3x - 2 ) ( x - 4 ) ( 6 - 5x ) / ( 8x - 1 )

What is rational function equation?

A rational equation can be defined as an equation that involves at least one rational expression

A rational function is a function of the form f( x )=P( x ) / Q( x ) ,

f( x ) = P( x ) / Q( x ) , where P( x ) and Q( x ) are both polynomials.

A rational function f ( x )=P( x ) / Q( x )

f( x ) = P( x ) / Q( x ) may have a vertical asymptote

The domain is the set of all real numbers for which Q( x ) ≠ 0

Given data ,

a)

Let the first function be P ( x ) = ( 15x⁷ - 45x⁵ )

Let the second function be Q ( x ) = 3x⁴

On simplifying , we get

A = P ( x ) / Q ( x )

A = ( 15x⁷ - 45x⁵ ) / 3x⁴

A = 3x⁴ ( 5x³ - 15x ) / 3x⁴

On further simplification , we get

A = ( 5x³ - 15x )

b)

Let the first function be P ( x ) = ( 15x⁷ - 45x⁵ )

Let the second function be Q ( x ) = 3x⁴

On simplifying , we get

B = P ( x ) / Q ( x )

B = ( 3x - 2 ) ( x - 4 ) ( x - 4 ) ( 6 - 5x ) / ( 4 - x ) ( 8x - 1 )

B = - ( 3x - 2 ) ( x - 4 ) ( x - 4 ) ( 6 - 5x )  / ( x - 4 ) ( 8x - 1 )

On further simplification , we get

B = - ( 3x - 2 ) ( x - 4 ) ( 6 - 5x ) / ( 8x - 1 )

Hence , the rational equations are solved
