Answer:
41 degrees to the nearest degree.
Step-by-step explanation:
A line drawn from the vertex and bisecting the base forms 2 right triangles.
The base of one right triangle = 1/2 * 12 = 6 m.
So cos A = adjacent side /hypotenuse where A is the angle of inclination.
cos A= 6 / 8 = 0.75
m < A = 41.41 degrees.
Answer:
is infinite set... because dots meaning non stop
Hello!
First, we must calculate the area of the base by using the formula, which is 3.14 × r × r × h
(I cannot access symbols on my device right now, otherwise I would've used the pi symbol and squared. Sorry, dude/dudette!)
Substitue:
A = 3.14 × 9 × 9
A = 28.26 × 9
A = 254.34 cm squared
Next, we must multiply the area of the base by the height to find the volume:
V = 9 × 254.34 squared
V = 2,289.06
Since there is no option for 2,289.06,the volume for the figure above is D. None of the above.
I’m pretty sure the answer is -7 B
Answer:
Pete
Step-by-step explanation:
Given that:
Mandy's Estimate :
Number of spins , n = 20
Pete's Estimate:
Number of spins, n = 200
A good probability estimate is one which has narrow margin of error with a high degree of confidence. These two variables are affected by sample size.
A high sample size give a narrower margin of error and increases the confidence level probability
Based on the sample size used by each of Pete and Mandy, we can conclude that, Pete's probability estimate would be better due to its significantly higher sample size.
