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.
Answers
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.

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

t=10709.69810694
Hope this helps! :)
or
t = 0.0100043 in decimal form.
Some simple math.
First, let’s get rid of easily divisible numbers.
5 = 500 * e^(-0.00043) * t
Let’s divide both sides by 5 so we can have one on the left side of the equation, where anything multiplied would stay the same value.
5/5 = 500/5 * e^(-0.00043) * t
1 = 100 * e^(-0.00043) * t
As for Euler's number, the exponent is negative, and numbers to a negative power over one is the same as one over the absolute value of the exponent.
1 = 100 * e^(-0.00043) * t
1 = 100 * 1/e^(0.00043) * t
We can multiply 100/1 with 1/e^(0.00043) to simplify.
1 = 100 * 1/e^(0.00043) * t
1 = 100/e^(0.00043) * t
Divide t on both sides.
1 = 100/e^(0.00043) * t
1/t = 100/e^(0.00043) * t/t
1/t = 100/e^(0.00043)
With any fractions the equal the same, flipping one means you just have to flip the other. If the ratios are equal, nothing will happen to the validity of their equivalence.
1/t = 100/e^(0.00043)
t/1 = (e^0.00043)/100
t = (e^0.00043)/100)
So, you have your answer in the simplest form. If you want to go the step further, you can get decimal form too. Just multiply the exponent and divide to get
t = 0.0100043

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

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
Answers
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
