If the sphere shown above has a radius of 11 units then what is the approximate volume of the sphere

adell [148]

Answer:

Volume of the sphere $=5563.58units^3$

Step-by-step explanation:

Volume of the sphere= $\frac{4}{3} *\pi *r^3$

The sphere has given radius(r)= 11 units

Putting the value of the radius in the formula;

Volume of the sphere:

= $\frac{4}{3} *3.14*11*11*11$

$=1.33*3.14*11*11*11$

$=4.18*11*11*11$

$=4.18*1331$

Volume $=5563.58units^3$

The volume of the sphere with radius of 11 units is $5563.58units^3$

Answer:. This would be 0.81^20 for none of the 19=0.0148

Step-by-step explanation:With a tree diagram, there are two possibilities, one is ND from 1 D from 2, with probability (5/8)(2/5)=(1/4) and the other is (3/8)(3/5)=9/40 That would be 19/40 for the answer.

3. Poisson parameter lambda=5

for P(0), it is e^(-5)(5^0)/0! or e^(-5)=0.0067

for P(1), it is e^(-5)(5^1)/1! or 5e(-5)

The total probability is 6e^-5 or 0.0404

4. the mean is 1000 hours, so lambda is the reciprocal or 1/1000

the probability it will last <800 hours is 1-e^(-800*1/1000) or 1-e^(-.8)=0.5507

5. assume p=0.4 since it ca't be 4

sd is sqrt (np*(1-p))=sqrt (6*0.6=sqrt(3.6)=1.90

A volleyball player sets the ball in the air, and the height of the ball after t seconds is given in feet by h= -16^2+12t+6. A t

JulsSmile [24]

h=-16²+12t+6

8=-256+12t+6

256-6+8=12t

-258=12t

t=-258/12

t=21.5
