Answer:
176
Step-by-step explanation:
all the angles equal 360*
so 80 plus 55 = 135
so the equation is x + 49 + 135 = 360
combine like terms 49 plus 135 = 184
x+184=360 subtract 184 from both sides to get x = 176
The length of the room is 156 inches because 8 x 156 is 1248
I think this helps, like a lot!
Given a data set consisting of 33 unique whole number observations, its five-number summary is: [19,32,47,61,77] how many observations are strictly less than 32?
Solution: The five number summary denotes:
Minimum = 19
First Quartile = 32
Median = 47
Third Quartile = 61
Maximum = 77
Since there are an odd number of observations (33) in the data set, the First Quartile (32) must be at the (33+1)/4 = 8.5th position, meaning there are 7 numbers less than 32.
Therefore, there are 7 observations that are strictly less than 32
