The 5 - number summary :
Min____ Q1 ___ median ____ Q3 ____ max
7 ______ 9 _____ 12 _______ 15 _____ 18
Answer:
Hence, from the 5 number summary, about 75% of sons have fewer than 15 stylist.
Step-by-step explanation:
Explaining the table :
Minimum number of stylist salons have = 7
Maximum number of stylist = 18
Q1 = first quartile, (25 /100) ;About 25% of salons have fewer Than 9 stylist
Q2 = second quartile or median ; About 50% of salons have fewer Than 12 stylist
Q3 gives the 75th percentile value.
Q3 = third quartile (75/100) ; About 75% of salons have fewer Than 15 stylist
Answer:
5√10, answer C
Step-by-step explanation:
You can use Pythagoras for this.
calculate the distance between the x coordinates (Δx), which is done by taking the biggest number and subtracting the the coordinates from each other. Aka 2 - - 3 = 2 + 3 = 5
Δy = 5 - - 10 = 15
then a^2 + b^2 = c^2 gives
5^2 + 15^2 = 250
c = √250
Then you still have to simplify. This is done by extracting the root out which results in an integer (a whole number), which is in this case 25.
√250 = √25 * √10 = 5√10, so answer C
