Answer:
letters = 46536
Step-by-step explanation:
letters + packages = 50995
letters + 4459 = 50995
letters = 50995 - 4459
letters = 46536
Considering the given stem-and-leaf plot, the quartiles are given as follows:
- The first quartile is of 67.5.
- The second quartile, which is the median, is of 84.5.
- The third quartile is of 91.5.
<h3>What are the median and the quartiles of a data-set?</h3>
- The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.
- The first quartile is the median of the first half of the data-set.
- The third quartile is the median of the second half of the data-set.
There is an even number of elements(26), hence the median is the mean of the 13th and 14th elements, which are 83 and 86, hence:
Me = (83 + 86)/2 = 84.5.
The first half has 12 elements, hence the first quartile is the mean of the 6th and 7th elements, which are 67 and 68, hence:
Q1 = (67 + 68)/2 = 67.5.
The third half also has 12 elements, starting at the second 86, hence the third quartile is the mean of the 6th and 7th elements of this half, hence:
Q3 = (91 + 92)/2 = 91.5.

Answer:
Never
Step-by-step explanation:
Adding together an obtuse angle (greater than 90°) and acute angle (less than 90°) should result in an obtuse angle every time
Since it's parallel, then the slope is the same
use the point slope formula and plug in the slope and point
y-y1=m(x-x1)
y-4=-4(x+2)
y-4=-4x-8
y=-4x-4
this is in slope intercept form
A) Interest = principal * rate * time
I = (800)(0.05)(3) = $120
b) $800 + $120 = $920 after the three years. $920 * (1 - 0.02) = $901.60.
