Answer:
y = (-1/2)x + 21/2
Step-by-step explanation:
Given equation:
y - 2x + 7
Coordinates = (5,8)
Find:
Perpendicular equation
Computation:
y = mx + c
y - 2x + 7
y = 2x - 7
So,
m = 2
The negative reciprocal of 2 is -1/2
So,
For,
Coordinates = (5,8)
y = mx + c
8 = (-1/2)(5) + c
8 = -5/2 + c
c = 8 + 5/2
c = 21 /2
So,
y = mx + c
y = (-1/2)x + 21/2
Answer:
4x - 5y = 10
Step-by-step explanation:
Any line parallel to 4x - 5y = 35 will have the same equation EXCEPT that the constant will be different.
Starting with 4x - 5y = 35, replace x with the given x-coordinate -5 and the given y-coordinate -6, and finally the given 35 with the constant C:
4(-5) - 5(-6) = C, or
-20 + 30 = C. Thus, C = 10, and the equation of the new line is
4x - 5y = 10
The probability that either the girls' or boys' team gets a game is 0.85
Step-by-step explanation:
Step 1:
Let P(G) represent the probability of girls team getting a game and P(B) represent the probability of the boys team getting a game.
P(B ∪ G) represents the probability of either girls and boys team getting a game.
P(B ∩ G) represents the probability of both girls and boys team getting a game.
Step 2:
It is given that P(G) = 0.8, P(B) = 0.7 and P(B ∩ G) = 0.65
We need to find the probability of either girls or boys team getting a game which is represented by P(B ∪ G)
Step 3:
P(B ∪ G) = P(B) + P(G) - P(B ∩ G)
= 0.8 + 0.7 - 0.65 = 0.85
Step 4:
Answer:
The probability that either the girls' or boys' team gets a game is 0.85
