#1- Jennifer made a box plot to summarize this data. 124, 118, 129, 139, 133, 129, 142, 135, 122, 137. What is the median, the l

Answer:
B or
Lower quartile: 124
Median: 131
Upper quartile: 137
Step-by-step explanation:
To find the median first make the data in order from greatest to least:
118,122,124,129,129,133,135,137,139,142
Then find the middle 2 numbers which are 129 and 133
129+133=262 (divide by 2 to find average) so
median= 262/2=131
To find the Lower quartile find the number in the middle of the first 5 numbers which is 124
To find the Upper quartile find the number in the middle of the second 5 numbers which is 137 so
B or
Lower quartile: 124
Median: 131
Upper quartile: 137
Answer:
$25.20
Step-by-step explanation:
First, take the 50% off the sales price:
($48)*(-0.50) = -$24.
($48 - $24) = $24 sale price.
Tax on $24 is ($24)*(0.05) = $1.20
Add the price and sales tax:
$24 + $1.20 = $25.20
Answer:
26.8°
Step-by-step explanation:
The cosine of an angle is the ratio of the adjacent side of the triangle in which the angle is formed to the hypotenuses side of the triangle. The cosine of the angle gives the ratio of these sides. However, the arc cosine of the ratio gives the angle measured in degrees.
If cos B = 0.8926
then arc cosine 0.8926 which may be expressed as cos-1 0.8926 will give the value of B.
B = cos-1 0.8926
= 26.8°
