Answer:
0.66608
Step-by-step explanation:
Equipment = 3 fans
Mortality = 0.098
We are required to find probability that equipment gets to work for 5years
The question says forces of mortality is constant and also equal to 0.098
To calculate p(x>5)
We will do this by calculating exponentially
e^-0.098x5
= 0.612626394
Probability that at least 2 fans out of 3 are working
3(0.612626394)²+(1-0.612626394)+(0.612626394)³
= 1.1259333x0.3873736+0.2299255
= 0.6660823470
This is approximately
<u>0.6608</u>
this is the probability that the equipment will work for at least 5years
I think is D , hope i answer fast enough haha :D
For Q3, you can subsitute x = 2 and y = 5 into the systems
-5(2) + 5 = -5
so it's a solution for the first system
-4(2)+2(5) = 2
it's also a solution for the second system
Answer:
Theorem 10.5: If two parallel lines are cut by a transversal, then the exterior angles on the same side of the transversal are supplementary angles.
Hello there! :)
Answer:

<h2><u><em>
*****The answer should have a GREATER THAN SIGN AND POSITIVE TOO!*****</em></u></h2>
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
PEMDAS
Order of operations
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
Left/Right
First, you add by 4 from both sides of an equation.

Then, you add numbers from left/right.
4+4=8
, which is our final answer.
Hope this helps you!
Have a nice day! :)
