Answer:
<h2>864π in³</h2>
Step-by-step explanation:
Volume of the water is equivalent to the volume of a cylinder = πr²h where;
r is the radius of the cylindrical tank
h is the height of the water
Given parameters
radius of the cylindrical tank r = 1feet = 12 inches
height of the water inside the tank = 6inches
Volume of the water = πr²h
Volume of the water = π(12)²*6
Volume of the water = π*144*6
Volume of the water = 864π in³
<em></em>
<em>Hence the volume of the water is 864π in³</em>
Answer:
.Lower quartile = 3.5
Step-by-step explanation:
Rearranging the data from lowest to highest.
2, 3, 4, 5, 6, 7, 8, 9 , 10, 15
First finding the median to make it easier to find the lower quartile.
median : 6 and 7 but right now they're irrelevant so we don't honestly need to work that out.
The lower quartile would be 3 and 4
3+4= 7 divide by 2 = 3.5 is your lower quartile
Answer:
Emma can play for more than one minute.
Step-by-step explanation:
1/4 is the same as 2/8 because 1/4*2=2/8.
2/8 is much smaller than 7/8.
Emma can play for 3 1/2 minutes in total.
Answer: D) Increase the sample size and decrease the confidence level.
Step-by-step explanation:
A reduced interval width means that the data is more accurate. This can only be achieved if the sample size is increased because a larger sample size is able to capture more of the characteristics of the variables being tested.
A smaller confidence interval will also lead to a reduced interval width because it means that the chances of the prediction being correct have increased.
