Answer:
Option (3)
Step-by-step explanation:
Steven has created a box plot to record the number of students who attended the science club meeting.
In a box plot, initial dot represents the minimum number and extreme point represents the maximum number.
From the graph attached,
Maximum number of students who attended the meeting are 32.
Therefore, Option (3) will be the correct option.
Answer:
Sample mean from population A has probably more accurate estimate of its population mean than the sample mean from population B.
Step-by-step explanation:
To yield a more accurate estimate of the population mean, margin of error should be minimized.
margin of error (ME) of the mean can be calculated using the formula
ME=
where
- z is the corresponding statistic in the given confidence level(z-score or t-score)
- s is the standard deviation of the sample (or of the population if it is known)
for a given confidence level, and the same standard deviation, as the sample size increases, margin of error decreases.
Thus, random sample of 50 people from population A, has smaller margin of error than the sample of 20 people from population B.
Therefore, sample mean from population A has probably more accurate estimate of its population mean than the sample mean from population B.
You need to set up a portportation to solve this question to do so you need to know that 3 tenths is 30% so you can do:
30/100 = x/1.7
So now you cross multiply doing 30X17=510
Finially X=510/100
Simpified Answer is 5.1 liters
3. 8 tires for 2 cars = 4 tires for every 1 car
4. (8,2) (12,3) (16,4) (20,5) (24,6) (28,7)

plot these on the graph
6. 8/2=16/4=12/3=20/5
Answer:
If the statement is true, lines a and b are parallel
Step-by-step explanation:
This is due to lines intersecting with line m at identical angles.
