The mean of eight numbers is 41. The mean of two of the numbers is 29. What is the mean of the other six numbers
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

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 35 hours and the median is 31.2 hours. 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. Step 1 of 5: Based on the given information, determine if the following statement is true or false. The 55th percentile is greater than or equal to 30 hours.
1: Approximately how many families are in the sample? Round your answer to the nearest integer.
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.
3: What is the value of the 50th percentile?
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.
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.

Give your answer as an expression in terms of
π
.
Answer:
pi
Step-by-step explanation:
First find the circumference of the circle
C = 2 * pi*r
C = 2 * pi *2
C = 4pi
A quarter circle is 1/4 of a circle
1/4 C = 1/4 (4pi)
1/4C = pi

fine t12 term in an arithmetic progression having t3=10 and t10=-4
✍ 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.

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
We want <C

9. Divide 15x^7-45x^5/3x^4
10. Divide (3x-2)(x-4)-(x-4)(6-5x)/(4-x)(8x-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

The formula for the nth term of the arithmetic sequence first term is 9 common difference is -2
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]

Find x. Round your answer to the nearest tenth of a degree. (marking BRAINLEST)
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
