Answer:
2827.4ft.^3
Step-by-step explanation:
Volume of a Cone:
V = πr^2 h/3
V = π·15^2·12/3
= 2827.43339
Rounded to the nearest tenth = 2827.4ft.^3
Hope this helps :)
Answer:
15
Step-by-step explanation:
let r represent red marbles then white = 2r + 5 and total is 20, thus
r + 2r + 5 = 20 ( subtract 5 from both sides )
3r = 15 ( divide both sides by 3 )
r = 5 ← number of red marbles
Thus number of white = 20 - 5 = 15
Answer:I believe is 66 days
because we
48,36,18
36-18=18
48-36=12
so the next moviewill be 48+12=66 days
Step-by-step explanation:
Part a: For variable X using z score you have (x-30)/10, replace X for this expression in (a), i mean Z=2+10((x-30)/10) = 2+x-30= put this in the way of z score = (x-18)/1, so the mean is 18 and standard deviation is 1.
Part b: Z=X+Y= (x-30)/10 + (x-20)/8 = solve adding fractions = (18x-440)/80 now divide all the numbers between 18 (because you need to show as z score way) = (x-24.4)/4.4, so the mean is 24.4 and standard deviation is 4.4.
For part c,do the same.
