Answer:
B. Median is greater than the mean and the majority of data points are to the right of the mean.
Step-by-step explanation:
Mean = sum(x × p(x))
= (1×0.1)+(2×0.15)+(3×0.2)+(4×0.45)+(5×0.1)
= 3.3
Probability of more than 3.3 is:
0.45 + 0.1 = 0.55 > 0.5
Answer:
9
Step-by-step explanation:
The first simplification we can make is to replace 6^0 with 1.
The first rules of exponents we can apply are ...
<em>(a·b)^c = a^c·b^c</em> . . . . . . similar to the distributive property
<em> (a^b)^c = a^(b·c)</em>
This reduces your expression to ...
Now we can apply another two rules of exponents:
<em> (a^b)(a^c) = a^(b+c)</em>
<em> 1/a^b = a^-b</em>
Using these, we have ...
The value of the expression is 9.
1/40 would be your answer.

Answer:
an = 17 +5(n -1)
Step-by-step explanation:
The first term can be found by working backward from the third term:
third term = 27
second term = 22 . . . . subtract 5 from 3rd term
first term = 17 . . . . . . . . subtract 5 from 2nd term
The generic term is given by the formula ...
an = a1 + d(n -1) . . . . . a1 = first term; d = common difference
Here, we have a first term of 17 and a common difference of 5. So, the sequence terms are described by ...
an = 17 +5(n -1)
−10x + 1 + 7x = 37
combine like terms
-3x +1 = 37
subtract 1 from each side
-3x = 36
divide by -3 on each side
x = -12
