Answer:
A) 210
Step-by-step explanation:
The percentage of students who have a cell phone plan with company x is student with plan x over total.The total is 130
P(x) = 70/130
The number of students with cell phone company x is found by multiplying the total number of students times the percentage of students with company x
Students with company x = total * P(x)
= 390 * 70/130
= 210
Volume of a cone is equal to pi*r^2*(h/3)
3.14*5^2*2/3 = 52.36 cubic cm.
Density = mass/volume
6 grams/ 52.36 cm^3= 0.1146
Round to 2 decimal places to get D.0.11 g/cm^3
I believe that the answer is c. An angle forms by two,rays that share the same endpoint. Hope this helps
