B is false, since by the inclusion/exclusion principle,
By independence, we have , which is zero if either of or is 0, which isn't guaranteed.
Answer:
answer C
Step-by-step explanation:
ive done it before
y=10
4 SX +20 Y= 822
Elimination
X - 10 -4
UX - 822-20Y
6.5
10 -4 = 822-201
45
- 4.5 = 822 - 204
15.54=774
4 = 90:13
= -40.129
24 make the brainliest pls
P(-2,-1) and Q(4,3)
average of x-coordinates = (-2+4)/2 = 1
average of y-coordinates = (-1+3)/2 = 1
midpoint of PQ: (1,1)
distance between midpoint and Q = √((4-1)²+(3-1)²) = √13
(x-1)² + (y-1)² = 13
y is also 2.
2x^2 = 8
2^3 = 8
