Answer:

Learn to find the sine, cosine, and tangent of 45-45-90 triangles and also ... Until now, we have used the calculator to evaluate the sine, cosine, and tangent of an angle. However, it is possible to evaluate the trig functions for certain angles without ... This is because there are two special triangles whose side ratios we know!

DochEvi [55]

Hello from MrBillDoesMath!

Answer:

r = C/6.28


Discussion:

Note that C = 2 * Pi * r is the exact formula. As Pi is approximately 3.14, the given formula, C = 2 (3.14) r, is an approximation.  Solving it for r:


C = 2(3.14) r               =>                as 2 * 3.14 = 6.28

C =  6.28 r                 =>                divide both sides by 6.28

r ( 6.28/6.28) = C/6.28 =>           as 6.28/6.28 = 1

r = C/6.28


Thank you,

Using your calculator, find the proportion of observations from a standard normal distribution that satisfies the following stat
emmainna [20.7K]
<span>Look at your table for a Z value of 1.55. The numbers on the far left column are your z values. See the 1.5 row, then move over to the 0.05 column to make it 1.55.
You'll see 0.9394.
That's the area under the normal curve from 1.55 to negative infinity.
But you wanted the area under the curve greater than 1.55.
Take 1-0.9394=0.0606.
You subtract from 1 because you know that the area under the whole curve is 1, so it gives you the area you need.</span>
