Answer:
7/11
Step-by-step explanation:
7y +6+4y+13=26
firstly collect like terms
7y+4y+6+13=26
11y+19=26
11y=26-19
11y=7
then divide through by 11
y=7/11
Answer:

Step-by-step explanation:
The PDF of X is
The PDF of Y is
The means of X and Y are respectively,
so we can see that the larger the parameter, the smaller the mean. Hence the PDF of Z = min(X, Y) is an exponential with the largest parameter of the two.
Therefore, the PDF of Z is
Answer:
162 hours
Step-by-step explanation:
1 day= 24 hours
24 times 6= 144
144 + 18= 162
"log" standing alone actually means "logarithm to the base 10."
Thus, y = log x <=> y = log x
10
y
Stated another way (inverse functions), x = 10
X=2 because 3 times 2 is 6 and then you add 6 and 7 together and get 13.
