Mean is 45,000
median is 1,500
Answer:
Are not one-to-one functions
Step-by-step explanation:
As m(x) has symmetry at the line x=0, it is not one-to-one
As n(x) has symmetry at the line x=-6, it is not one-to-one
Answer:
For an nth term U(n) = a + ( n - 1)d
n = number of terms
a = first term
d = common difference
a = -9
d = -3--9 = -3+9 = 6
U(n) = -9 + (n - 1)6
That's option A.
Hope this helps.
The answer would be 6.2 then 7
Answer:
option B
2
Step-by-step explanation:
Given in the question
DO,h(7, 9) → (14, 18)
Formula to use
<h3>√(x1-x2)²+(y1-y2)²</h3>
distance formula = √((7-0)²+(9-0)²) = √(7²+9²) = √130
distance formula = √((14-0)²+(18-0)²) = √(14²+18²) = 2√130
Scale factor
√130 = 2√130
d = 2d
