Answer:
the 90th percentile is 145
Step-by-step explanation:
Data provided:
152 121 130 143 122 101 137 98 138 127 145 117
Number of students considered, n = 12
To find:
90th percentile
Now,
Step 1 : Arrange the data in ascending order
98, 101, 117, 121, 122, 127, 130, 137, 138, 143, 145, 152
Step 2 : Compute the position of the 90th percentile
position of the 90th percentile, i = (90% × n)
Thus,
i = 0.90 × 12
or
i = 10.8
Now,
Step 3 : Since, the index i is not an integer, round up to the nearest integer
i.e i = 11
Therefore,
The 90th percentile is the value in 11th position,
i.e 145
Answer:
10.3
Step-by-step explanation:
Let the given points be the endpoints of a right triangle. The horizontal change in x is from 4 to -5 and is negative 9; the vertical change in y is from -2 to+ 3 and is +5.
The desired distance is found using the Pythagorean theorem:
d = √(9² + 5²) = √106, or 10.3 (to the nearest tength)
