Answer:
a) C. The random variable is discrete. The possible values are xequals0, 1, 2,....
b) B. The random variable is continuous. The possible values are x greater than or equals 0.
Step-by-step explanation:
Discrete variables are countable in a finite amount of time. Continuous variables can be infinitely many. They rather assume values in a range.
<u><em>(a) Is the number of hits to a Web site in a day discrete or continuous? </em></u>
C. The random variable is discrete. The possible values are x equals 0, 1, 2,....
<u><em>(b) Is the weight of a Upper T dash bone steak discrete or continuous?</em></u>
B. The random variable is continuous. The possible values are x greater than or equals 0.
1 + 3n + 7n = 7(n + 4) + 6(3n + 3)
1 + 3n + 7n = 7n + 28 + 18n + 18
10n + 1 = 25n +46
25n - 10n = 1 - 46
15n = -45
n = -45/15
n =-3
Answer:
15625
Step-by-step explanation:
25^3
The base is 25 and the power is 3
That means we multiply 25 together 3 times
= 25*25*25 =15625
Answer:
y= -3
Step-by-step explanation:
<u>Multiply all terms by the same value to eliminate fraction denominators:</u>
2/y +3 = 3/3y + 9
(3y+9) (y+3) (2/y+3) = (3y +9) (3/3y+9)
<u>Simplify:</u>
6

1
8
=
3
+
9
<u>Subtract 18 from both sides of the equation:</u>
6y +18 =3y +9
6y+18 -18 =3y +9 -18
<u>Simplify Again: </u>
6y +3y-9
<u>Subtract 3y from both sides of the equation:</u>
6y =3y -9
6y-3y = 3y -9 -3y
<u>Answer:</u>
y= -3
