<span>Given the diagram, where AB and EF are horizontal lines and CB is a vertical line segment.
Given that FB : FC = 4 : 3,
From the diagram, the coordinate of A is (-10, -8) and the coordinate of C is (-3. -1).
We can also see that the coordinate of B is (-3, -8) (since CB is a vertical line means that B is the same x-value as C and AB is a horizontal line means that B is the same y-value as A)
Recall that the coordinate of a point dividing a line segment in the ratio m:n is given by (x1 + m/(m+n) (x2 - x1), y1 + m/(m+n) (y2 - y1))
Thus, since FB : FC = 4 : 3, this means that point F divides the line segment BC in the ratio 4 : 3.
Thus, the coordinate of F is given by (-3 + 4/(4+3) (-3 - (-3)), -8 + 4/(4+3) (-1 - (-8))) = (-3 + 4/7 (0), -8 + 4/7 (7)) = (-3, -4).
Also, given that FB : FC = 4 : 3, this means that point D divides the line segment AC in the ratio 4 : 3.
Thus, the coordinate of D is given by (-10 + 4/(4+3) (-3 - (-10)), -8 + 4/(4+3) (-1 - (-8))) = (-10 + 4/7 (7), -8 + 4/7 (7)) = (-6, -4).
Therefore, the coordinates of point D is (-6, -4).</span>
The probability that suits of cards are spades, hearts, and spades is 39/850 or 0.046.
According to the give question.
Three cards are drawn from a standard deck of cards without replacement.
Since,
The total number of cards in a standard deck = 52
Total number of spade cards = 13
Total number of heart cards = 13
Now,
The probabbility of getting first card as a spade card = 13/52 = 1/4
The probability of getting second card as heart card
= 13/(52 -1) (cards are drawn without replacement)
= 13/51
The probability of getting third card as a spade card
= (13 - 1)/52 -2
= 12/50
= 6/25
Therefore, the probability that suits of the cards are spades, hearts, spades
= 1/4 × 13/51 × 6/25
= 39/850
= 0.046
Hence, the probability that suits of cards are spades, hearts, and spades is 39/850 or 0.046.

Answer: y= 3x
Step-by-step explanation:
1. The question lack info
Answer:
8x -12
Step-by-step explanation:
Use the distributive property. 16 outside wishes to go inside and multiply each term; you get 16x/2 which is 8x minus ¾ of 16 which is 12.
