Please find the surface area of the cone (image attached) and reduce answer to nearest tenth, if necessary.
Luba_88 [7]

Answer:

S.A = 135.6 yd^2 (

Step-by-step explanation:

Surface area of cone is given as:

Surface Area (S.A) = πr(r + l)

Where,

r = radius = 3 yd

l = slant height = 11.4 yd

Take π as 3.14

Plug the given values into the formula to find the surface area.

S.A = 3.14*3(3 + 11.4)

S.A = 9.42(14.4)

S.A = 135.6 yd^2 (rounded to the nearest tenth)

If you roll a die 100 times, what is the approximate probability that you will roll between 9 and 16 ones, inclusive? (Round you
Ann [662]

Answer: 0.47

Step-by-step explanation:

Given that

n = 100, probability of rolling 1 = 1/6

binomial approximation

np = 100 ( 1/6) = 16.667

standard deviation = √ 100 × 1/6 ×5/6 = 3.7627

P ( 9 ≤ X ≤ 16 )

= P ( 8.5 < X < 16.5 )

so,

= P ((8.5 - 16.6667) / 3.7627 < Z < (16.5 - 16.6667) / 3.7627

= P ( -2.17 < Z < -0.04 )

= 0.484 - 0.015

= 0.47

Therefore the approximate probability that you will roll between 9 and 16 ones is 0.47
