With a calculator, press second or shift and then tan to find the degrees.
Answer:
E
Step-by-step explanation:
As you need a 47%, you universe of numbers should be form 0 to 99 (or 1 to 100, the important fact is you need 100 numbers). With this, you can discard A and D. You can also discard C, as you need 47 good realizations as you probability is 47%, and C gives you 48 (00 also counts)
You need as many observations as you can, to get a more consistent estimation. This means, as many observations as you can. You could use B or E, because both have 47 good observations (for u), but E gives you a larger sample.
If you are trying to get a head with 50% throwing a dime, you will, statistically, do better throwing it 47 times than only 10 times.
Answer:
13.95 cm
Step-by-step explanation:
the volume of the cone =
⅓× π r². h = 180 π
⅓×π r²×15 = 180 π
(eliminate π)
=> 5r² = 180
r² = 180/5 = 36
r=√36 = 6 cm
the volume of the sand = ½×4/3 π r³
= ⅔× π ×6³ = 144π cm³
the ratio of the volume :
144π/180π = 0.8
so the value of <em>h</em><em> </em><em> </em><em>=</em><em> </em><em>³</em>√0.8 x 15 = 0.93× 15
= 13.95 cm
We need to see the graph. Ask Question again with graph attached.
