Answer:
3/4
Step-by-step explanation:
Given two points , we find the slope using the formula
m = (y2-y1)/(x2-x1)
= ( 5 - -1)/ ( 6 - -2)
= (5+1)/( 6+2)
= 6/8
= 3/4
<span>There are 16 sweatshirts in total.
7 of which are cotton.
There are 4 friends.
Say they all choose cotton sweatshirts,
First friend: (7/16)
Second friend: (6/15)
Third friend: (5/14)
Fourth friend: (4/13)
As you can see, there is a deduction in total number of sweatshirts available to be chosen and also in the total number of cotton sweatshirts available to be chosen.
Multiply these together = </span><span>(7/16)*(6/15)*(5/14)*(4/13)
= </span><span>0.01923076923 = 1.92%
1.92% is the probability all friends order cotton sweatshirts</span>
<em>C</em>
Approximately 95% of data falls within 2 standard deviations (±2) of the mean.
<em>Explanation</em>
According to the empirical rule of normal distribution:
Approximately 68% of the data falls within ±1 standard deviation of the mean
2. Approximately 95% of the data falls within ±2 standard deviations of the mean
3. Approximately 99.7% of the data falls within ±3 standard deviations of the mean.
Therefore, among the given options, only option C adheres to the empirical rule of the normal distribution. Therefore, the option C is correct
