Answer: The slope is: "3" ; which does not appear among the answer choices given.
______________________________________________
The slope, "m" is calculated as follows:
___________________________________
Given two coordinates on a line;
m = (y₂ − y₁) / (x₂ − x₁) ;
__________________________________________
We are given the following 2 (TWO) coordinates:
__________________________________________
1) (5,2) ; which is: (x₁ ,y₁) ; so x₁ = 5 ; y₁ = 2 ; AND:
2) (7,8); which is: (x₂ ,y₂) ; so x₂ = 7; y₂ = 8 ;
_____________________________________________
So; m = (y₂ − y₁) / (x₂ − x₁) = (8−2) /.(7−5) = 6/2 = 3 .
m = 3. The slope is: 3 ; which does not appear among the answer choices given.

Alternately,
______________________________________________
We are given the following 2 (TWO) coordinates:
__________________________________________
1) (7,8) ; which is: (x₁ ,y₁) ; so x₁ = 7 ; y₁ = 8 ; AND:
2) (5,2); which is: (x₂ ,y₂) ; so x₂ = 5; y₂ = 2 ;
______________________________________________
So; m = (y₂ − y₁) / (x₂ − x₁) = (2−8) / (5−7) = -6/-2 = 3 .
m = 3. The slope is 3 ; which does not appear among the answer choices given.

Answer:
25%
Step-by-step explanation:
{(whole- part)/whole}*100%
(64 -48)/64 *100%= 25%
Answer:
A) 0.4255
B) 0.5813
C) 0.5588
D) 0.7241
Step-by-step explanation:
Assuming that the probability for each case is the same, we can calculate the probability by dividing the number of favourable cases with the total amount of cases. You can find the total amount of cases by adding the favourable ones with the non favourable ones, so, the probability of each case would be:
A) 20/(27+20) = 20/47 = 0.4255
B) 25/(18+25) = 25/43 = 0.5813
C) 19/(15+19) = 19/34 = 0.5588
D) 21((8+21) = 21/29 = 0.7241
Answer:
a.
b.
Step-by-step explanation:
We are given that two cards are drawn are randomly selected from a standard 52- cards deck.
Total cards=52
Total number of spade cards=13
Probability=
a.The probability of drawing two cards first card is spade and second card is spade without replacement =
The probability of drawing two cards first card is spade and second card is spade=
b. The probability of drawing two cards first is spade and second card is a spade with replacement =
The probability of drawing two cards first is spade and second card is a spade with replacement =
