Answer:
Interval [16.34 , 21.43]
Step-by-step explanation:
First step. <u>Calculate the mean</u>

Second step. <u>Calculate the standard deviation</u>



As the number of data is less than 30, we must use the t-table to find the interval of confidence.
We have 6 observations, our level of confidence DF is then 6-1=5 and we want our area A to be 80% (0.08).
We must then choose t = 1.476 (see attachment)
Now, we use the formula that gives us the end points of the required interval

where n is the number of observations.
The extremes of the interval are then, rounded to the nearest hundreth, 16.34 and 21.43
Answer:

Explanation:
Build your conversion factors using the conversion table:
From the prefixes used in the metric system, you know that 1 deciliter = 0.100 liters. Then:
Arrange the expression to simplify the units and convert from cups to deciliters:
Round to the nearest tenth: 0.2 deciliter.
The radius is 8
Im not sure if this is what your looking for
The altitude is 6/4 but originally it’s 16 hope this helps ;)
Answer:
cut up the shape
Step-by-step explanation:
if you are looking for area make the 18 yard a triangle so then you have a rectangle and add them together. try this for practice so you can do it on your own next time:)
