Answer: 0.750
Step-by-step explanation:
Let p be the population proportion .
We are given that a sample of 400 voters reveals that 300 would support her in the November election.
Then the sample proportion for this situation will be :-
Since the sample proportion is the best point estimate for the population proportion.
Therefore, the estimated value of the population proportion =0.750
Well I think that for this problem we should multiply 3x1/3 which is 1 whole. Sorry if I'm incorrect.
Answer:
(A)
Step-by-step explanation:
Given: BLUE is a quadrilateral.
To prove: Quadrilateral BLUE is a parallelogram.
Proof: By the definition of parallelogram, the opposite sides of the parallelogram are equal and parallel.Thus, we have to prove that the opposite sides of quadrilateral BLUE are equal and parallel.
Now, (BL and EU) and (BE and LU) are the opposite sides of the parallelogram BLUE, thus all we need is to prove that BL║EU ..
Therefore, Option A is correct.
Answer:
- 220 options, 84 options, 20 options, 1 option
Step-by-step explanation:
<h3>The first dinner</h3>
Combinations of 3 out of 12 items
- 12C3 = 12!/(12-3)!3! = 12!/9!3! = 12*11*10/2*3 = 220
<h3>The second dinner</h3>
Combinations 3 out of remaining 9 items
- 9C3 = 9!/(9 - 3)!3! = 9!/6!3! = 9*8*7/2*3 = 84
<h3>The third dinner</h3>
Combinations of 3 out of remaining 6 items
- 6C3 = 6!/(6 - 3)!3! = 6!/3!3! = 6*5*4/2*3 = 20
<h3>The fourth dinner</h3>
Combinations of 3 out of 3 remaining items
- 3C3 = 3!/(3 - 3)!3! = 3!/0!3! = 1
Answer:
<em>The first answer is d and second answer is a</em>
Step-by-step explanation:
3×n×(n+1)×(2n+1)/6 - 8×n
Putting n = 11
3×11×22×23/6 - 8×11
1430
<em> The answer is 1430 option d</em>
