Answer:
The probability is 169/2652
Step-by-step explanation:
The number of cards in a deck of cards is 52
In each deck of cards, there are 13 black cards and 13 spade cards
The probability of selecting a spade card will be;
13/52 = 1/4
Without replacement, we are left with 51 cards and the probability of selecting a black card will now be 13/51
So the probability of the second card being a black card if the first is spade will be ;
13/52 * 13/51
= 169/2,652
The approximate side length of a square game board with an
area of 184 in^2 is 14 inches
<h3>Area of a square</h3>
The formula for calculating the area of a square is expressed as;
A = l^2
where
l is the side length of a square
Given the following parameters
A = 184 square inches
Substitute
184 l^2
l = √184
l = 13.56
Hence the approximate side length of a square game board with an
area of 184 in^2 is 14 inches

Answer:
the volume of the box increases 48 times compared to the 1st one.
Step-by-step explanation:
Volume of the box (1) = LWH
- length of a box is increased 4 time = 4L
- width is increased 4 times = 4W
- the height is tripled = 3H
=> The new volume of the box = 4L * 4W * 3H = 48LWH
So the volume of the box increases 48 times compared to the 1st one.
