2 answers:
Answer:
Step-by-step explanation:
Distance (how far the submarine travelled) can be found by multiplying the speed by the time.
The speed is 2.4 kilometers per hour.
The time is 0.25 hours.
Substitute the values into the formula.
Multiply. Note that the hours (hr) will cancel each other out.
The submarine travelled <u>0.6 kilometers</u> in 0.25 hours.

Answer:
a) E(y) = 0.8
b) The average subcharge is $165
Step-by-step explanation:
We are given the following distribution in the question:
y: 0 1 2 3
P(y): 0.50 0.25 0.20 0.05
a) E(y)
b) Expected value of subcharge
Subcharge =
Expected value of subcharge =
Thus, the average subcharge is $165

We have the equation of a line in the slope-point form:
use distributive property
add 3 to both sides
multiply both sides by 2
subtract x from both sides
