Step-by-step explanation:
From the take on a sample of 60 homes from this neighborhood and 14 fitting in the criteria. The appropriate null and alternative hypotheses a is best expressed in option c.
H0: pbar <= 0.20: HA: pbar > 0.20
Answer:
The answer to your question is: y = -1/2 x + 3
Step-by-step explanation:
Data
slope = m = 2
y-intercept = 3
line l is ⊥
Process
1.- Calculate the slope of line l
l = - 1/ m
l = - 1 / 2
(m)(l) = (2)(-1/2)
= -1 As m x l is "-1" the lines are perpendicular
2.- Find the line of line l
Equation y - y1 = m (x - x1)
Point (0, 3)
y - 3 = - 1/2 (x - 0) Substitution
y - 3 = -1/2 x Simplification
y = -1/2 x + 3
Given:
The arithmetic sequence is:
To find:
1. The rule for the nth term of the given arithmetic sequence.
2. The 10th term of the given arithmetic sequence.
Solution:
1. We have,
Here, the first term is 1 and the common difference is:
The nth term of an arithmetic sequence is:
Where, a is the first term and d is the common difference.
Putting , we get
Therefore, the nth term of the given sequence is .
2. We need to find the 10th term of the given arithmetic sequence.
From part 1 it is clear that the nth term of the given arithmetic sequence is:
Putting , we get
Therefore, the 10th term of the given arithmetic sequence is 46.
Answer:
½ r² ∅
The area of a sector of a circle is ½ r² ∅, where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle. So in the below diagram, the shaded area is equal to ½ r² ∅ .
