Answer:
0.0060
Step-by-step explanation:
The z-score is given by
<em>z = (866,475-722,500)/57,429 = 2.51
</em>
The probability is given by the area under the Normal curve N(0,1) to the <em>right</em> of 2.51
In <em>Excel </em> this value is found with the formula
=1-NORMDIST(2.51,0,1,1)
and in <em>OpenOffice Calc
</em>
=1-NORMDIST(2.51;0;1;1)
<em>
(NORMDIST(2.51;0;1;1) gives the area to the left of 2.51, so 1-NORMDIST(2.51;0;1;1) gives the area to the right of 2.51)
</em>
and equals 0.0060
Dimeter is 28inch and area is equal to 26.7inch^2
Answer: <em>1.1 × 10⁸ cm³</em>
Explanation:
1) Since the ball is spherical, you use the volume formula for a sphere, which is:
Volume = [4/3] π r³
2) r is the radius, which is given and is equal to 3×100cm = 300cm
3) Pluging in the value of r, you get:
Volume = [4/3] π (300 cm)³ = 113,097,335.53 cm³
4) Since, r = 3×100 cm has two significant figures, the result must show only two significant figures.
So, using scientific notation, the right answer must be reported as:<em> 1.1 × 10⁸ cm³</em>
