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
Brainly isn’t letting me insert a picture but the anwser is y<2+3x/4
Answer:
d
Step-by-step explanation:
using the distance formula
d = 
with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (10, 1 )
d = 
= 
= 
= 
= 
≈ 12.369
Answer:
slope = - 2
Step-by-step explanation:
calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 1, 8 ) and (x₂, y₂ ) = (5, - 4 )
m = 
= 
= 
= - 2
