Answer:
It is an unusual result contradicting the national survey.
Step-by-step explanation:
National survey showed 44% of college students who drink.
The professor's survey showed that 96/244 = 39% drink.
The professor's survey deviated from the national survey is 5% (44% - 39%) representing about 0.25% (5% squared) variance.
Standard deviation is the spread of a set of numbers from their mean. In other words, it measures how far an observed value is from the mean. It can be calculated by getting the square root of the variance.
36 divided by 90 gives the percent so its 0.4 which is 40%
Answer:
she is wrong because 1800/9 is 200.
Here is your solution,
(-5)^2 - √25 - 4 x (-14)/2
25 - √ 25 + 56/2
25 - √81/2
(25 - 9)/2 = 16/2 = 8
or
25 + √25 +56/2
25 + √81/2
(25 + 9)/2 = 34/2 = 17
So m = 8,17
Answer:
Step-by-step explanation:
Trend line passes through the points (6,12) and (4,16).
Find the slope of the line:
Write the equation of the line in the form 
where the slope 
This line passes through the point (6,12), then its coordinates satisfy the equation:
