The numbers in the output sequence are ...
[tex]o_n=o_1+d(n-1)\\\\o_n=6+4(n-1)=4n+2=2(2n+1)\\\\o_n=2\times i_n[/tex]

A university dean of students wishes to estimate the average number of hours students spend doing homework per week. The standard deviation from a previous study is 6.2 hours. How large a sample must be selected if he wants to be 99% confident of finding whether the true mean differs from the sample mean by 1.5 hours
Answers
Answer:
The Sample Size Need To be at least 114
Step-by-step explanation:
According to the Question,
Given, A university dean of students wishes to estimate the average number of hours students spend doing homework per week. The standard deviation from a previous study is 6.2 hours.The Maximum Error(E) is given as 1.5 hours and the standard deviation(σ) is 6.2 hours.
Now, For 99% Confident the level of value α is 0.01.α/2 = 0.01/2 ⇒ 0.005
Thus, From The table, We get that the value of [tex]Z_{alpha/2}[/tex] is 2.58.Hence, the sample size n can be found as
n = {[tex]\frac{(Z_{alpha/2} * Standard Deviation)}{E}[/tex]}²
n = {2.58 × 6.2}² / 1.5²
n = 113.72 .
So, The Sample Size Need To be at least 114.
0.36% as a fraction in simplest form
Answers
Answer: 9/2500
Step-by-step explanation:
We start with turning it into a fraction:
0.36/100
Then, we turn every number into a whole number by multiplying by whatever the last decimal place is called (hundreth= x100)
36/10000
Lastly, we simplify as much as we can by finding the least common denominator. In this case, the smallest whole number both 36 and 10000 can be divided by is 4:
(36/4)/(10000/4)
= 9/25000

In general, half of all the customers you speak to will ask about any upcoming pricing discounts or promotions. Of those who do ask, only 20% qualify for the discount. So that means if I speak to 300 customers, how many will qualify for the discount
Answers
Answer:60
Step-by-step explanation:
300 of 20% is 60
The number of qualified customers for the discount will be 60.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
It is given that half of all the customers you speak to will ask about any upcoming pricing discounts or promotions. Of those who do ask, only 20% qualify for the discount. So that means if I speak to 300 customers.
The number of qualified customers will be calculated as below:-
The qualified customers are 20% of 300.
Number = 300 x (20/100)
Number = 300 x 0.2
Multiply the number 330 with 0.2 to get the final value.
Number = 60
Therefore, the number of qualified customers for the discount will be 60.

Every weekend Felicia is paid $30 to do the gardening for her
grandparents. She is saving her money to buy a new bike that
costs $189. So far, she has saved $60.
What is the minimum number of weekends she'll have to
continue to do the gardening in order to have the $189 she
needs for the bike?
Answers
Answer:
5 weekends
Step-by-step explanation:
Felicia already has 60$ of her goal of 189$ so 189-60=129
129/30=4.3
Felicia would need to work exactly 4.3 weekends to make up her goal, but you cant split a weekend into decimals, so we round up to the next whole number which is 5.
Answer:
she needs to work a minimum of 5 weekends
Step-by-step explanation:
60 + 30w ≥ 189
30w ≥ 129
w ≥ 4.3

The club with an occupancy of 100 will sell out at $25 per ticket. If the owner decides to increase the price by $5, then 2 less tickets will be sold. Determine the revenue function if x is the number of $5 increases.
Answers
Answer:
100 + (5X) = -2X
Step-by-step explanation:
Since the club with an occupancy of 100 will sell out at $ 25 per ticket, and if the owner decides to increase the price by $ 5, then 2 less tickets will be sold, to determine the revenue function if X is the number of $ 5 increases the following calculation must be performed:
100 + (5X) = -2X
So, for example, if the price were increased by $ 15, the equation would apply as follows:
15/5 = 3
100 + (5x3) = -2 x 3
100 + 15 = -6
115 = -6

Answers
Answer:
first you need to know that the the sum of the co-interior angle is 180 degree and the sum of the opposite side of parallelogram is always equal.
now x+140=180(being co - interior angle)
or, x= 180-140
therefore, x =40 degree
y= 140 degree because sum of the opposite side of parallelogram is always equal.
x= z=40 degree (sum of the opposite side of parallelogram is always equal.

Find the area of a circle with
radius, r = 5.52m.
answer rounded to 2 DP.
Answers
Answer:
Step-by-step explanation:
Formula = A=πr2
Putting values in the equation
A = (3.14) (5.52)^2
= 95.73
Answer:
95.73
Step-by-step explanation:
2 decimal points is what the question MEANS:
formula for finding a cirlce (and this is not from the internet)
r^2 times pi
(5.52)^2 times pi
which (5.52) squared becomes a sickly: 30.4704 in decimals
lets say you WANT to keep the decimals, then multiply 30.4704 by 3.14159265359 and absolutely get every single decimal place added in and THEN round it to 2 decimal places (once i didn't do this, i got bad grades in math class)
the answer is 95.7255847919
the decimal place of this is 95.73 not 95.72 or something,
the answer is 95.73
Which equation represents the function y - 5 = –2(x+3) in slope-intercept form?
Oy= 2x + 1
Oy = 2x - 1
Oy= -2x - 1
Oy = -2x + 11
Oy = -23 - 11
Answers
Answer:
-2x-1
Step-by-step explanation:
when you graph the equation it gives you a decreasing slope with the y intercept of -1. the slope is 2 and since its decreasing it is -2. therefore its -2x-1
The solution is, the function y - 5 = –2(x+3) in slope-intercept form is y = -2x -1 .
What is a straight line?A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.
here, we have,
given that,
the function y - 5 = –2(x+3)
now, we have to find in slope-intercept form.
now, we have,
function has a decreasing slope with the y intercept of -1. the slope is 2
and since its decreasing it is -2.
again, we have,
y - 5 = –2(x+3)
or, y = -2x - 6 + 5
or, y = -2x -1
here, slope = m = -2
and, y-intercept = c = -1
as, we know that,
slope-intercept form is: y = mx+ c
so, we get, y = -2x -1
Hence, The solution is, the function y - 5 = –2(x+3) in slope-intercept form is y = -2x -1 .

LN and MO both equal 43
Step-by-step explanation:
LN and MO are diagonals in rectangle
Diagonals of a rectangle are congruent Hence, 4x - 17 = 2x + 13
Now we solve for x
4x - 17 = 2x + 13
Add 17 to both sides
4x = 2x + 30
Subtract 2x from both sides
2x = 30
Divide both sides by 2
x = 15
Now we want to find the values of LN and MO
To do so we substitute 15 for x in it's given expression ( note: because LN = MO we only need to do this process once )
LN = 4x - 17
Substitute 15 for x
4(15) - 17
Multiply
60 - 17
Subtract
LN and MO = 43

A market research firm conducts telephone surveys with a 42% historical response rate. What is the probability that in a new sample of 375 telephone numbers, at least 150 individuals will cooperate and respond to the questions
Answers
Answer:
The right answer is "0.7823".
Step-by-step explanation:
Given that,
P = 42%
or,
= 0.42
n = 375
[tex]\hat{P}[/tex] = 0.4
The z-score will be:
= [tex]\frac{\hat{P}-\mu_P}{\sigma_p}[/tex]
By putting the values, we get
= [tex]\frac{0.4-0.42}{\sqrt{\frac{0.42\times (1-0.42)}{0.375} } }[/tex]
= [tex]-0.784706[/tex]
hence,
The probability will be:
⇒ [tex]P(\hat {P}>0.04)[/tex] = [tex]P(z>-0.7847)[/tex]
= [tex]1-P(z<-0.7847)[/tex]
= [tex]1-0.21770[/tex]
