There is a higher chance that person is male by one in 39. Hope this helps!!!
Sample size, N = 3450
Point estimate of republican, p = 1789/3450 = 0.5186 = 51.86%
Z = 1.96 at 95% confidence level
Now,
True percentage of republican residing in California = p +/- Z*Sqrt [p91-p)/N] = 0.5186+/- 1.96* Sqrt [0.5186(1-0.5186)/3450] = 0.5186+/-0.017 = (0.5016,0.5356) = (50.16%,53.56%).
Answer:
True
Step-by-step explanation:
I remembered learning this definition for a matrix:
A Matrix is an arrangement of numbers into rows and columns
so yes matrices consist of rows and columns
Answer:
45 units
Step-by-step explanation:
See the given diagram with the question here.
The point D and point E are the midpoints of line segments AC and BC respectively.
Therefore, the length of the line joining points D and E will be half of length AB.
Now, given that AB = 11x - 25 and DE = 4x + 1.
Hence, ( 11x - 25 ) = 2 ( 4x + 1 )
⇒ 3x = 33
⇒ x = 11
Therefore, length DE = 4x + 1 = 4 ( 11 ) + 1 = 45 units. (Answer)
