The perimeter of the base of a regular quadrilateral prism is 60 cm, the area of one of the lateral faces is 105 cm2. Find:

Ostrovityanka [42]

The surface area is 870 cm².

Since the base is a regular quadrilateral, each side is the same; dividing the perimeter by 4 will give us the side length:

60/4 = 15

To find the area, we square the side length:
15² = 225

There are two bases, so the area of these is 2(225) = 450

There are 4 lateral faces, so the lateral area is 4(105) = 420

Together, this gives us a total surface area of 870.

Roma selects cards from a standard of 52 cards. Once a card is selected, it is not replaced. Find the probability of each outcom

meriva

Given:

A card is selected randomly from a standard deck of 52 cards.

To find:

The probability of each outcome.

a. a king of heart

b. a queen of spades

c. an ace of flower

d. an ace of diamond

Solution:

In a standard deck of 52 cards.

Total number of cards = 52

13 cards of each suit (heart, diamond, club, spade).

13 cards are Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King.

a. We need to find the probability of getting a king of heart.

Number of king of heart = 1

$P(\text{a king of heart})=\dfrac{\text{Number of king of heart}}{\text{Total cards}}$

$P(\text{a king of heart})=\dfrac{1}{52}$

b. We need to find the probability of getting a queen of spades.

Number of queen of spades = 1

$P(\text{a queen of spades})=\dfrac{\text{Number of queen of spades}}{\text{Total cards}}$

$P(\text{a queen of spades})=\dfrac{1}{52}$

c. We need to find the probability of getting an ace of flower (spades).

Number of ace of flower = 1

$P(\text{an ace of flower})=\dfrac{\text{Number of ace of flower}}{\text{Total cards}}$

$P(\text{an ace of flower})=\dfrac{1}{52}$

d. We need to find the probability of getting an ace of diamond.

Number of ace of diamond = 1

$P(\text{an ace of diamond})=\dfrac{\text{Number of ace of diamond}}{\text{Total cards}}$

$P(\text{an ace of diamond})=\dfrac{1}{52}$

Therefore, the required probabilities for each parts are:

(a) $\dfrac{1}{52}$

(b) $\dfrac{1}{52}$

(c) $\dfrac{1}{52}$

(d) $\dfrac{1}{52}$
