Answer:
Yes they are
Step-by-step explanation:
11(p+q) = 11p + 11q
---------------------------
11p + (7q+ 4q)
= 11p + ( q * (7+4))
= 11p + (q * 11)
= 11p+ 11q
See they are the same

From the provided information:
Compute the expression of <em>T</em> as follows:

Compute the value of <em>C</em> in terms of <em>A</em>:

Compute the value of <em>A</em> as follows:
Use expressions (i) and (ii):

Compute the value of <em>T</em> as follows:

Thus, the total number of books is 1020.
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:
f(x) = x + 9
Step-by-step explanation:
y = f(x) + C C > 0 moves it up
To shift it up 9 units
f(x) = x + 9
