Answer:
<em>The probability of getting exactly 2 of the cards are spades out of 6 cards will be </em><em>0.315</em>
Step-by-step explanation:
6 cards are drawn at random from a standard deck of 52 cards.
The number ways 6 cards can be drawn from a deck of 52 cards will be,

In a deck of 52 cards, 13 cards are of spades. So drawing 2 spades out of 13 is,

As exactly 2 must be spades, so the remaining 4 cards must be drawn from other 39 cards of other suits. This can be done in,

The probability of getting exactly 2 of the cards are spades out of 6 cards will be,

Answer: 55%
Step-by-step explanation:
Number of pizzas sold that were pepperoni = 11
Total pizza sold = 20
Percentage of pizza that were pepperoni will be:
= Number of pepperoni pizzas/Total pizza sold × 100
= 11/20 × 100
= 11 × 5
= 55%

The volume of the spherical dome will be 12.9π cubic feet when the surface area of the dome is 13.924π.
<h3>What is the volume of the sphere?</h3>
The volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. The dome is the shape of a semi-sphere the volume of the dome will be half of the volume of the sphere.
Given that the Reunion Tower in Dallas, Texas, is topped by a spherical dome that has a surface area of approximately 13,924π square feet.
The volume of the dome will be calculated as below:-
SA = 13.924π
2πr² = 13.92π
r = √6.96
r = 2.63 feet
Volume = 2 / 3 πr³
Volume = ( 2 / 3 ) π ( 2.63)³
Volume = 12.24π cubic feet
Therefore, the volume of the spherical dome will be 12.9π cubic feet.
