Answer:
The volume of the cylinder is <u>141.23 cubic feet </u>
Step by step explanation :
<u>Given</u>-
- Radius of cylinder = 3 feet
- Height of cylinder = 5 feet
Now, we know that
<h3>
</h3>
where, r is the radius of the cylinder & h is the height of the cylinder.
Now,
Volume of the cylinder =
<h3>
</h3>
( approximately )
I believe it is the last answer choice
Answer:
Step-by-step explanation:
Recall the mnemonics SOH-CAH-TOA
The sine ratio is the length of the opposite side expressed over the hypotenuse.
Take the sine inverse of both sides to get;
The cosine ratio is the length of the adjacent side expressed over the hypotenuse.
Take the cosine inverse of both sides to get;
The answer is 360 -15 times -24 equals 360
Answer:
we can conclude that there is no significant evidence to conclude that the mean score in 2010 differs from the mean score in 2009.
Step-by-step explanation:
H0 : μ = 582
H1 : μ < 582
Test statistic :
T = (xbar - μ) ÷ σ/√n
Xbar = 515 ; n = 20 ; σ = 120
T = (515 - 582) ÷ 120/√20
T = -67 / 26.832815
T = 2.50
Pvalue at t score = 2.50 ; df = 19 is 0.0187
At α = 0.0187
Pvalue > α ; Hence, we fail to reject the Null
Hence, we can conclude that there is no significant evidence to conclude that the mean score in 2010 differs from the mean score in 2009.
