10% of 450 is 45, so 1500 divided by 45 is 33.3 continuous. so she needs 34 weeks to pay off the last of the debt
Answer:
The IQR of the data set is 4.5
Step-by-step explanation:
Given:
10 13 15 12 12 4 12 17
12 13 15 18 10 11 20 19
Now, to determine the IQR (interquartile range) of this data set.
So, <em>we need to set the data in numerical orders:</em>
4 10 10 11 12 12 12 12
13 13 15 15 17 18 19 20
Now,<em> we split this in half and get the medians of both half:</em>
<u>4 10 10 11 12 12 12 12 </u> Median 1 = 11.5
<u>13 13 15 15 17 18 19 20 </u> Median 2 = 16
Getting the medians of both half now we subtract the median 1 from median 2:
IQR = 16 - 11.5
IQR = 4.5.
Therefore, the IQR of the data set is 4.5
Answer:
g (f(0)) = -4.5
Step-by-step explanation:
Find f(0) = (3(0)-7)/4 = -7/4
sub this into g(x)
g(-7/4) = 2 (-7/4) -1 = -14/4 - 4/4 = - 18/4 = -4.5
