Answer:
See explanation.
Step-by-step explanation:
- A terminating decimal is a decimal that has an end.
- A repeating decimal is a decimal fraction in which a number, or a group of numbers, is repeated indefinitely.
- Most repeating decimals contain a nine in the denominator, when written in fraction form.
- Both can be written in fraction form.
- Both can have a positive or negative value that can be both large and small.
First arrange the data in an order
3, 3, 3, 7, 7, 10, 10, 12, 12, 13, 14, 17, 17, 18, 21
a.) Q1 = (N + 1)/4th item = (15 + 1)/4 = 4th item = 7
Q2 = 2(16)/4 = 16/2 = 8th item = 12
Q3 = 3(16)/4 = 3(4) = 12th item = 17
IQR = (Q3 - Q1)/2 = (17 - 7)/2 = 10/2 = 5
b.) 82nd percentile = 82(16)/100 = 13th item = 17
c.) 12 is the 8th item which is in the middle of the data set, so the percentile rank is 50%
Answer:
Write the larger number above the smaller number. ...
Multiply the number in the ones place of the bottom number by the number in the ones place of the top number. ...
Multiply the number in the ones place of the bottom number by the number in the tens place of the top
Steps to solve:
f(x) = 3x³ – 2x² + x; x = -3
~Substitute
f(-3) = 3(-3)³ - 2(-3)² + (-3)
~Solve the exponents
f(-3) = 3(-27) - 2(9) + (-3)
~Multiply
f(-3) = -81 - 18 - 3
~Subtract
f(-3) = -102
Best of Luck!
