Answer:
(0.767,0.833)
Step-by-step explanation:
The 95% confidence interval for population proportion p can be computed as
The z-value associated with 95% confidence level is 1.96.
whereas p=x/n
We are given that x=440 and n=550.
p=440/550=0.8
Thus, the required confidence interval is
0.767<P<0.833 (rounded to 3 decimal places)
Hence, we are 95% confident that our true population proportion will lie in the interval (0.767,0.833)
The diagram of rhombus JKLM is shown in the diagram below
A rhombus is a quadrilateral with four equal sides and its diagonals intersect perpendicular to each other (makes 90° angles). Opposite angles are equal (the same with a parallelogram). Each diagonal bisects the angle at J, K, L, and M equally
If angle JKL is 104°, the measurement of angle JKN is 104÷2=51°
The answer should be 110 degrees.
This is assuming that the lines are parallel, which they should be.
Best of luck.
Answer:
(x + 2)(x - 4)
Step-by-step explanation:
Given the zeros of a function, say x = a and x = b, then
the factors are (x - a) and (x - b)
From the graph
The zeros are x = - 2 and x = 4, thus the factors are
(x - (- 2)) and (x - 4), that is (x + 2) and (x - 4)
