Answer:
Mean: 7.9
Median: 7
Mode: 6
Step-by-step explanation:
Sort the date set!
1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15
Then start by finding the mean of the data set!
Mean: the sum of all numbers divided by the amount of numbers
Mean = 1 + 2 + 6 + 6 + 6 + 7 + 9 + 11 + 12 + 12 + 15 = 87 divided by 11 = 7.9
Median: middle number in the data set
Data set: 1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15
Median = 7 because it is in the middle
Mode: the number that is being used the most
Data set: 1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15
Mode = 6 because it is used 3 times
Answer:
(5*sqrt(2), 5pi/4)
Step-by-step explanation:
In Polar coordinates, tan(theta)=y/x and r=sqrt(x^2+y^2)
tan(theta)=-5/5=-1. Theta=5pi/4
r=sqrt(5^2+5^2)=5*sqrt(2)
Hence the Polar coordinate is (5*sqrt(2), 5pi/4)
Answer:
Step-by-step explanation:
y - 1 = 3(x + 4)
y - 1 = 3x + 12
y = 3x + 13
or
slope -3
y - 1 = -3(x + 4)
y - 1 = -3x - 12
y = -3x - 11
That the result will be negative
because
a negative number, example -2 is equal to -1 times 2
odd power
even powers cancel negatives
so examle
(-2)^3=((2^3)((-1)^3)=(8)(-1)=-8
the concluseion is that the result will be negative
