Answer:
- C. The IQR is the best measure of variability because the distribution has an outlier.
Step-by-step explanation:
We see 75% of data lies in the interval 0 - 48, and the 120 is the outlier.
We wouldn't use the range as it won't be a representation of variability.
<u>The best measure would be IQR:</u>
- <em>The interquartile range is the best measure of variability for such a distribution. </em>
- <em>Because it's based on values that come from the middle half of the distribution, and not influenced by outliers</em>
Correct choice is C.
Answer:
Rate = 10%
Step-by-step explanation:
We are given with the following details.
Interest earned = $ 116.25
Principal = $ 1550
Interest Rate = r (say)
Time = 9 months
= 
We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .
The formula for simple interest is given as
r=0.1
Hence the r = 0.1
Hence the rate of interest is 10%
Answer:
y = -10x + 82
Step-by-step explanation:
Plug in the slope and point into y = mx + b to solve for b:
y = mx + b
2 = -10(8) + b
2 = -80 + b
82 = b
Then, plug b and the slope into y = mx + b
y = -10x + 82 is the equation in point slope form.
What they are asking is tell to true things about the graph. And one thing that is untrue about it. For example: Lie, The slope of this graph is 5. Truths, The graph is steep, and has a constant rate of change.
C because there is an exponent... as long as they match up they can go as high up as they want
