A right cylinder ice cream cone has 600 cubic centimeters of ice cream, what is the radius of the cone of the height is 15 centi
choli [55]
The formula for volume is V=Bh where  B is the area of the base. 
plug in what they have given you:
600=B(15) you can divide both sides by 15

40=B    We know that a cylinder's base is a circle so we can use the area f                           formula for a circle to solve for the radius.
40 = pi(r)^2   divide both sides by pi to get the r^2 alone
40/pi=r^2     square root both sides to get rid of the square
you should get
r=3.5 approximately

Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock resistance. The results from 100 disks are sum
IrinaK [193]

Answer:

0.84

Step-by-step explanation:

Given that Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock resistance. The results from 100 disks are summarized as follows:

P(A) = 0.86, P(B) = 0.79, P(A') = 0.14, P(AUB) = 0.95

We are to find out P(A'UB)

We have

P(AUB) =P(A)+P(B)-P(A\bigcap B)\\0.95=0.86+0.79-P(A\bigcap B)\\P(A\bigcap B)=0.70

P(A'UB) = P(A')+P(B)-P(A' \bigcap B)\\= 1-P(A) +P(B)-[P(B)-P(A \bigcap B)]\\= 1-0.86+0.79-P(B)+[tex]P(A'UB)=0.14+0.79-0.79+0.70\\=0.84P(A \bigcap B)[/tex]
