Julie box contains two gold hoop earrings and two silver hoop earrings you randomly choose to errands what is the probability th

vesna_86 [32]

The total number of elements is 2+2=4. Since we have 2 silver earrings, we get

$P(two\text{silver earrings)}=\frac{1}{4}+\frac{1}{4}=\frac{2}{4}=\frac{1}{2}$

the, the probability to get two silver earrings is 1/2, which is equivalent to 0.5.

The volume of a cone with a height of 6 cm is 8pie cubic centimeters. Which expression can be used to find r, the radius of the

Kobotan [32]

The volume of a cone can be found by using the equation V=(1/3)(pi*r^2*H). Given the information that H= 6cm and V= 8pi cm^3, the expression is 8pi=(1/3)(pi*r^2*6). (The second picture.)
