Answer:
5.579 * or 0.00005579 %
Step-by-step explanation:
In this question, you select 11 random adults, so the order is not important and we should use combination instead of permutation. There are two different probability here
A= chance that the adults need correction= 0.81
B= chance that the adult doesn't need correction = 0.19
The case that can fulfill the condition of no more than 1 of 11 adults need correction is:
1. 0 adult need correction = 0C11 *
2. 1 adult need correction = 1C11 * *
Then the probability will be:
0C11 * +1C11 * * =
* + * *0.81 =
5.579 * = 0.00005579 %
The threshold for a significant value that widely used is 5% and the chance is lower than 5%, so no more than 1 adult need correction is a significantly low number of adults requiring eyesight correction?
Answer:
9
Step-by-step explanation:
9+9= 18
you find average speed with distance/time
average speed is 35 mph
if you multiply is by 11 you get your answer which is 385 miles
Not necessarily, it could be either the numerator or the denominator. For example, -3/4 (lets pretend that its one on top of the other) either the three or the four could be negative but not both. If both the numerator and denominator were negative, they would cancel each other out, making it a positive question. So to answer your question, it is no.
The answer is "A" because you need your equation to be like:
Ax + By = C
