Answer:
D
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = 4(x - 10) ← is in point- slope form
with slope m = 4
Given a line with slope m then the slope of a line perpendicular to it is
= - = -
The perpendicular line passes through (- 3, 7), hence
y - 7 = - (x - (- 3)), that is
y - 7 = - (x + 3) → D
Answer:
7/15
Step-by-step explanation:
To find the probability the student is a senior
P( senior) = number of seniors / total students
= 14 / ( 14+7+4+5)
= 14/30
= 7/15

Not necessarily.
and
may be linearly dependent, so that their span forms a subspace of

For example, we could have
