A. There is no coefficient of X.
Yuri [45]3 years ago
7 0
The answer is D because up and right means that the line has a positive slope. If the coefficient was 0, the line would be horizontal, not going up in any way. Technically A is correct because no coefficient means that the coefficient is 1, which is up and right. D is still the better answer because it better defines the problem.

In a​ lottery, 6 numbers are randomly sampled without replacement from the integers 1 to 50. Their order of selection is not i
nlexa [21]

Answer: 0.444225

Step-by-step explanation:

Given : The total number of tickets = 50

Number of tickets are randomly sampled without replacement  =6

Since the order of selection is not important , so we use combinations.

Total number of ways to select 6 tickets = ^{50}C_6

The number of winning tickets = 6

So, number of tickets that are not winning = 50-6=44

Number of ways of selecting zero winning numbers= ^{44}C_{6}

Now , the probability of holding a ticket that has zero winning numbers out of the 6 numbers selected for the winning ticket out of the 50 possible numbers would be \dfrac{^{44}C_{6}}{^{50}C_6}

=\dfrac{\dfrac{44!}{6!(44-6)!}}{\dfrac{50!}{6!(50-6)!}}\\\\\\=\dfrac{\dfrac{44\times43\times42\times41\times40\times39\times38!}{38!}}{\dfrac{50\times49\times48\times47\times46\times45\times44!}{44!}}\\\\\\=\dfrac{44\times43\times42\times41\times40\times39}{50\times49\times48\times47\times46\times45}\\\\=\dfrac{252109}{567525}\approx0.444225

Hence, the required probability = 0.444225
