<span>If you would like
to know the values of these two numbers, you can calculate this using the following
steps:<span>
a + b = 77.95
a - b = </span></span>30.61 ... a = 30.61 + b
________<span>_______________
a + b = 77.95
(30.61 + b)
+ b = 77.95
30.61 + 2 *
b = 77.95
2 * b =
77.95 - 30.61
2 * b
= 47.34 /2
b = </span>47.34<span> / 2
b = 23.67
a = </span>30.61 + b = 30.61 + 23.67<span> = 54.28
Result:
The numbers are </span>23.67<span> and 54.28.</span>
There are 2000 pounds in 1 ton

Answer:
A -9 is the y-intercept
Step-by-step explanation:
The event that either M1 or M2 fails has probability
by the addition rule. Failure events are independent, so
so that
Denote this probability by 
. Then 
follows a geometric distribution with this parameter and has density
The expectation is 
.
