Answer:
<em>the median is 21</em>
Step-by-step explanation:
<em>8 , 15 , 21 , 25 , 63 </em>
<em>that is what you have to do you would have to put them in order from least to greatest so then you would see the middle number which is 21</em>
Answer:
The highest point over the entire domain of a function or relation is called an <u>absolute maximum.</u>
<u />
Step-by-step explanation:
For a continuous function f(x) in a closed interval, there exists a value of f(x) that is the highest and that point is called the absolute maximum. The maximum value can be found a number of ways including a graphical method and using the first and second derivative.
The value of y should be 8
The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.
<h3>
Z score</h3>
Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

Where x is raw score, μ is mean, σ is standard deviation
Given that:
σ = 4, μ = 56, hence
for x = 62:

for x = 47:

for x = 56:

The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.
