<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
Answer:
J
Step-by-step explanation:
A basketball player makes a shot 72.1% of the time (0.721 as a decimal). Study the player's next three shots by doing the following.
a. Draw a tree diagram and label all of the probabilities on the tree.
b. Find and label the probability for each branch of the tree diagram.
c. Build a probability model showing the probability of the player 0, 1,2, or 3 shots.
To find value of X
We can use Pythagoras theorem...
(BC)^2=(AB)^2+(AC)^2
=>(X)^2=(5)^2+(5 root3)^2
=>(X)^2=25+75
=>(X)^2=100
=>X=root 100
=>X=10
