Answer:

3.0699

Step-by-step explanation:

V = pi*r^2*h

you have v and h and pi so you can get r

Answer:

V = 1/3 • π • radius cubed • height

If the volume is is 16π and the height is 3, then 16π = 1/3 • π • r cubed • 3

16π ÷ (1/3 • π • 3) = 16

radius squared = 16        √16 = 4, so radius = 4

You can also check: 1/3 • r cubed • 3 = 16    The only value left to multiply is π

Answer:

-1.99, 1.99

Step-by-step explanation:

Use a table to find the z-scores.

For the first z-score:

P(x < z) = 0.0233

z = -1.99

For the second z-score:

P(x > z) = 0.0233

P(x < z) = 1 − 0.0233 = 0.9767

z = 1.99

A rectangle prism has dimensions of 1/2, 2 and 7/2 inches. How many cubes with side edges of 1 inch will fit into the prism?
uysha [10]
Dimensions of the rectangular prism: a=1/2 inches, b=2 inches, c=7/2 inchesVolumen of the rectangular prism: Vr=abcVr=(1/2 inches)(2 inches)(7/2 inches)Vr=[ (1*2*7) / (2*2) ] inches^3Vr=14/4 inches^3Vr=7/2 inches^3
Side of the cube: s=1 incheVolume of the cube: Vc=s^3Vc=(1 inche)^3Vc=1 inche^3

Number of cubes will fit into the rectangular prism: nn=Vr/Vcn=(7/2 inches^3) / (1 inche^3)n=7/2n=3.5
3.5 cubes with side lengths of 1 inche will fit into the prism

3) An oil prospector will drill a succession of holes in a given area to find a productive well. The probability that he is succ
KATRIN_1 [288]

Answer: 0.128

Step-by-step explanation:

The geometric probability of getting success on nth trial is given by :-

P(n)=p(1-p)^{n-1}

Given : The probability that he is successful on a given trialp= 0.2.

Then , the probability that the third hole drilled is the first to yield a productive well is given by :-

P(3)=0.2(1-0.2)^{3-1}=0.128

Hence, the probability that the third hole drilled is the first to yield a productive well = 0.128
