Standard deviation (minutes) 1.45, 45 1.36
Number of observations 20 20
Which of the following are conditions for this type of test?
Choose all answers that apply:
A. The samples are both randomly selected.
B. The wait times within each sample are independent of each other.
C. The wait times within each group are approximately symmetric without outliers.
The conditions for this type of sampling test regarding the wait times at two branches of a bank include:
The samples are both randomly selected.The wait times within each group are approximately symmetric without outliers.What is sampling?It should be noted that sampling simply means a statistical process where a predetermined number of observations are taken from a larger population.
In this case, the samples are both randomly selected and the wait times within each group are approximately symmetric without outliers. When there's a symmetric distribution with no outliers, the mean and standard deviation will be used.

Find the volume of this composite figure
Answer:
381 feet cubed
Step-by-step explanation:
You need to divide the shape into 2.
I would divide the shape so that 8.5ft, 6ft, and 3ft are one.
Now do Length times Width times Height for the first one.
8.5 ft x 6 ft x 3 ft = volume for shape 1
The volume for shape 1 is 153 feet cubed
Now onto the second one.
Since you divide the other shape to have 8.5 feet the measurements are:
4ft, 9.5ft, and 6ft.
Do the formula lwh.
4ft x 9.5ft x 6ft = volume for shape 2
The volume for shape 2 is 228 feet cubed
Finally, you have to add shapes 1 and 2 due to the fact it's a composite figure.
153ft + 228ft = 381ft cubed
75 POINTS IF U GET THIS RIGHT !!!!!Every June 1, an ecologist takes a census of the number of wrens in a state park. She noticed that the number is decreasing by $40\%$ each year. If this trend continues, in what year will the census show that the number of wrens is less than $10\%$ of what it was on June 1, 2004?
Answer:
In 2009
Step-by-step explanation:
If the wren population is going down by 40% each year, that means the following year's population is just 60% of what was in the previous year. This means that what we have to do is multiply the previous year's number by 0.6 to get the current year's population. If we take the data from 2004 as 100%, we have the following numbers:
2004 = 100%
2005 = 60 % (100 * .6)
2006 = 36 % (60 * .6)
2007 = 21.6 % (36 * .6)
2008 = 12.96 % (21.6 * .6)
2009 = 7.776% (12.96 * .6)
This means that 2009 will show that the wren population is less than 10% (7.776%) than what it was in the year 2004.
I hope this helps! :D
Answer:
2009
Step-by-step explanation:
On June 1, 2004 we can say that there were 100% of the wrens.
If the number decreases by 40% each year, then each year there will be 60% of the previous years number. To find 60%, multiply by 0.6 (since 60% = 60/100 = 0.6)
June 1, 2004 = 100%
June 1, 2005 = 100% x 0.6 = 60%
June 1, 2006 = 60% x 0.6 = 36%
June 1, 2007 = 36% x 0.6 = 21.6%
June 1, 2008 = 21.6% x 0.6 = 12.96%
June 1, 2009 = 12.96% x 0.6 = 7.776%
Therefore, the census shows that the number of wrens is less than 10% in the year 2009.
Noah's Diner offers its clients a choice of regular and diet soda. Last night, the diner served
18 regular sodias and 57 diet sodas. What percentage of the sodas served were regular?
Answer: 24%
Step-by-step explanation:
for these problems you can use this equation: [tex]\frac{x}{n} *100=p[/tex]
where x=given quantity, n=total amount, and p is your answer.
for this problem x=18 (regular sodas)
we add the amount of regular and diet sodas to get n=75 (18+57)
when we plug it in we have [tex]\frac{18}{75} *100[/tex] which gives us our answer, p, 24%

Given that points Q, R, S lies between O and P meaning that the points are between 0 and 3
OQ = QR = RS = SPDraw a number line and find three equal points
so points:
Q = 0.75R = 1.5S = 2.25Answer:
[tex]\sf Q=\dfrac34, \ R=\dfrac32, \ S=\dfrac94[/tex]
Step-by-step explanation:
Given information:
O = 0P = 3Points Q, R and S are between O and POQ = QR = RS = SPTherefore, there are 4 segments of equal distance between points O and P.
Length of OP = 3 - 0 = 3
⇒ Length of each segment = 3/4
To find the point of Q, R and S, add 3/4 to each point:
Point O = 0
⇒ Point Q = 0 + 3/4 = 3/4
⇒ Point R = 3/4 + 3/4 = 3/2
⇒ Point S = 3/2 + 3/4 = 9/4
Point P = 9/4 + 3/4 = 3
Therefore,

each of two computers can process bills at 160/min a newer model can process bills at 200/min after the first two computers have worked 1.5 min they are joined by the third computer how long will it take from the time the first two computers are turned on to process 1780?
Based on the rate at which all three computers process bills, the time taken for the computers to process 1,780 bills is 4 minutes.
What is the time taken to process 1,780 bills?First find the number of bills left when the third computer joined:
= 1,780 - (160 x 1.5 mins) - (160 x 1.5 mins)
= 1,300
Then the average speed of all three computers is:
= 160 + 160 + 200
= 520 bills per minute
The time taken to finish up the other bills would be:
= 1,300 / 520
= 2.5 minutes
Add this to the minutes already elapsed before the third computer was used:

= 4 minutes
