Answer:
1/6
Step-by-step explanation:
Let X = amount of time (in minutes) a postal clerk spends with his or her customer. The time is known to have an exponential distribution with the average amount of time
X is a continuous random variable since time is measured. It is given that μ = 6 years. To do any calculations, you must know m, the decay parameter.
m = 1/μ = 1/6
So the decay rate is 1/6
The answer i think it is ,is b
When x=-4:
2(-4)+3y=4
3y=4+8
3y=12
y=4
So the ordered pair is (-4,4), I think
Answer: x is 52 and y is 38.
Step-by-step explanation:
x+128=180
x=52
52+y=90
y=38
Answer:
D. -3x+3y
Step-by-step explanation:
Start by distributing the -3 to each term in the parentheses:
-3(x)+(-3)(-y)
Here are some multiplication sign rules that will make this problem easier:
- - make a +
- + make a -
+ - make a -
+ + make a +
-3x+3y (note that since both 3 and y are negative, they make a positive)
