Answer:
Step-by-step explanation:
y = 4x + 1
Slope of line = 4
Slope of perpendicular to line = -¼
Point-slope equation for line of slope -¼ that passes through (12, -7):
y+7= -¼(x-12)
Answer:
4.5
Step-by-step explanation:
Answer:
what is the slope of Line A?
Step-by-step explanation:
once you have the slope of line a, you need to make the slope negative, and turn the number into its reciprocal, so if the slope of line a was 2/3, the perpendicular slope would be -3/2, you flip the fraction and make it a negative. if its a whole number you just put a one on top, so if the slope is 3, the perpendicular is -1/3
Answer:
1/8
Step-by-step explanation:
Answer:
A and B are not disjoint.
Step-by-step explanation:
Given that there are two events A and B with prob
P(A)=0.5,
P(B)=0.7
If A and B are disjoint, there should not be any common element between A and B
P(AB) should be 0
But here we find P(A) + P(B) = 1.2>1
Since total probability is 1, there must be 0.2 atleast in P(AB)
which implies A and B cannot be disjoint.
A and B are not disjoint.
