Answer:
The events "Spike passes chemistry" and "Spike passes mathematics" are not independent.
The probability that he fails both subjects = 0.37
Step-by-step explanation:
The probability of Spike passing Chemistry = P(Chemistry) = 0.35
The probability of Spike passing Mathematics = P(Mathematics) = 0.40
The probability of Spike passing both Chemistry and Mathematics = P(Chemistry,Mathematics) = 0.12
For the events "Spike passes chemistry" and "Spike passes mathematics" to be independent, P(Chemistry,Mathematics) should be equal to P(Chemistry) * P(Mathematics)
But P(Chemistry) * P(Mathematics)=0.35*0.40 =0.14
So the two events are not independent.
The Probability that he passes Chemistry or Mathematics is given by P(Chemistry) + P(Mathematics) - P(Chemistry,Mathematics)
= 0.35+0.40-0.12=0.63
So the probability that he fails both subjects is the complement of this, namely (1 - 0.63) = 0.37
A. The (x,y) coordinates where the equations y =4x and y = 2x - 1 intersect on a graph is the solution to that system of equations. When solving for this system of equations by substitution of y, the equation 4x = 2x -1 is obtained. So the x-coordinate obtained is both a solution to the equation 4x = 2x - 1 and the intersection point of the system of equations y = 4x and y = 2x - 1.
B. Idk about this part... Says to make a tables to solve for 4x = 2x - 1.
If you make a table for Eq. #1. y = 4x and Eq. #2. y = 2x -1 maybe..
#1. y = 4x
x ...... y
-4 .. -16
-3 .. -12
-2 .. -8
-1 .. -4
0 ... 0
1 ... 4
2 .... 8
3 ... 12
4 ... 16
the solution to 4x = 2x - 1 ; the x-coordinate is not an integer value so Idk what the point of this is.....
4x = 2x - 1
4x - 2x = -1
2x = -1
x = -1/2
not an integer..
C. You can solve the equation 4x = 2x - 1 graphically by graphing y = 4x and y = 2x - 1 and identifying the x-coordinate at the point of intersection.
All three altitudes lie entirely outside the triangle
