Answer:
1 : 1
Step-by-step explanation:
When a circle is inscribed in a cylinder, the height of the cylinder is equal to the diameter of the sphere and the radius of the cylinder is same as that of the sphere.
Let the radius of sphere is r.
height of cylinder, h = 2r
radius of cylinder = r
Surface area of sphere, A = 4πr²
lateral surface area of cylinder, A' = 2 πrh
A' = 2πr x 2r = 4πr²
The ratio of surface area of sphere to the lateral surface area of cylinder is 1 : 1.

Answer:increased percent = 66.67%
Step-by-step explanation:
The value of an autographed baseball card increased from 39$ to $65. This means that the price of the autographed baseball card increased from the original price to the new price by a certain percentage.
Let x percent = the percentage increase of the price of the autographed baseball card from the original price to the new price.
Percentage increase =
(New price of price of the autographed baseball card - the original price of the autographed baseball card) / the original price of the autographed baseball card × 100
From the information given,
New price of price of the autographed baseball card - the original price of the autographed baseball card = 65 - 39 = $26
Percentage increase = 26 / 39 × 100
= 66.67 %

Step-by-step explanation:
Answer: <em><u>157 tickets </u></em>
Explanation:
The people not showing up for the flight can be treated as from Binomial distribution.
The binomial distribution B(n, p) is approximately close to the normal i.e. N(np, np(1 − p)) for large 'n' and for 'p' and neither too close to 0 nor 1 .
Now, Let us assume 'n' = n
and we are given
p=0.15
So now B(n,0.15n) follows Normal distribution
u=n
= 0.15n
We have to calculate P(X<144) with 99% accuracy
P(X<144) = P(Z<z)
where;
z= 
z score for 99% is 2.33
i.e.
solving this we will get one root nearly equal to 157 and other root as 133
<u><em>Hence the answer is 157.</em></u>
