The inequality that is true is 7π > 21
<h3>How to determine the inequality that is true?</h3>
To do this, we simply test the given inequalities (starting from the first)
The first inequality is represented as
7π > 21
Divide both sides of the inequality by 7
So, we have:
7π/7 > 21/7
Evaluate the quotient of 21 and 7
So, we have:
7π/7 > 3
Evaluate the quotient of 7π and 7
So, we have:
π > 3
The above inequality is true.
This is so because π = 3.14 and 3.14 > 3
Hence, the inequality that is true is 7π > 21

Sin 20 = 1.8/hypotenuse
hypotenuse = 1.8 / sin 30 = 2.34 m
answer: 2.34m
A y=3x because 3*1 is 3 and 3*2 is 6 and so on
Answer: 
Step-by-step explanation:
The confidence interval estimate for the population mean is given by :-
, where
is the sample mean and ME is the margin of error.
Given : Sample mean: 
The margin of error for a 98% confidence interval estimate for the population mean using the Student's t-distribution : 
Now, the confidence interval estimate for the population mean will be :-

Hence, the 98% confidence interval estimate for the population mean using the Student's t-distribution =
