Answer:
Hello,
Step-by-step explanation:
We are going to use the pythagorean's theorem
distance (building ,ladder)=1+8=9 (ft)
level of the window = 11ft
length of the ladder:
questions
1) through: (2, 3), parallel to y = 4x - 1
2) through: (5, -4), parallel to y = -
3/5x +1
3)through: (1, 2), parallel to y = 6x + 3
4)through: (-1, -1), parallel to y = -4x + 1
answers=
1)y = 4x - 5
2)y = -
3/5-1
3) y = 6x - 4
4)y = -4x - 5
Answer: a) 1.07, b) 0.1423
Step-by-step explanation:
Since we have given that
n = 1400
Number of voters vote for Republican candidates = 720
So,
And hypothesis are :
(a) What is the z -statistic for this test?
(b) What is the P-value of the test?
p-value = P(Z>Z(statistics))
Hence, a) 1.07, b) 0.1423
