Greater than is your answer
Answer:
The expected value of X is and the variance of X is
The expected value of Y is and the variance of Y is
Step-by-step explanation:
(a) Let X be a discrete random variable with set of possible values D and probability mass function p(x). The expected value, denoted by E(X) or , is
The probability mass function of X is given by
Since the bus driver is equally likely to drive any of the 4 buses, the probability mass function of Y is given by
The expected value of X is
The expected value of Y is
(b) Let X have probability mass function p(x) and expected value E(X). Then the variance of X, denoted by V(X), is
The variance of X is
The variance of Y is
The direction given by Enzo's sister is an illustration of distance
Enzo's distance from the east of 1st avenue to the field is 6 miles
<h3>
How to describe the directions?</h3>
From the question, we have the following directions:
- Start at east of 1st avenue
- Drive 3 miles
- Make a 90 degrees right turn
- Drive 1 mile
- Turn at 90 degrees intersection
- Drive 2 miles
The above directions imply that the total distance from the east of 1st avenue to the field is:
Distance = 3 miles + 1 mile + 2 miles
Evaluate the sum
Distance = 6 miles
Hence, Enzo's distance from the east of 1st avenue to the field is 6 miles

Answer:
yes
Step-by-step explanation:
To know if x = 5 satisfy the equation or not, you just have to applied it into your equation:
3 (5+1) = 3 * 5 + 3
18 = 18
So x = 5 do satisfy the equation
Hope this help you :3
Answer:
A. yes, the data represents a function because u have no repeating x values. A function cannot have repeating x values...they can have repeating y values, just not the x ones
Step-by-step explanation:
B. table : (8,8)(12,12)(14,16)(16,16)
look at ur points...when x = 8, y = 8...so the table, when x = 8 has a
value of 8
relation : f(x) = 8x - 5....when x = 8
f(8) = 8(8) - 5
f(8) = 64 - 5
f(8) = 59....and the relation has a value of 59
Therefore, the relation has a greater value when x = 8 <==
C. f(x) = 8x - 5...when f(x) = 19
19 = 8x - 5
19 + 5 = 8x
24 = 8x
24/8 = x
3 = x <==
