3(6x-2)+ 2(x+5)
= 3*(6x)-3*2 +2x +2*5 (distributive property)
= 18x -6 +2x +10
= (18x +2x) +(10-6)
= 20x +4
The final answer is 20x+4.
Hope this helps~
Answer:
<h3>Therefore, So the correct answer is 0.3446</h3>
Step-by-step explanation:
Suppose parts A and B have a lifetime that is normally distributed with mean 110 hours and standard deviation 5 hours. Suppose further that parts A and B work independent of each other. What is the probability that the electric device works more than 112 hours
Here it is given that distribution is normal with
mean = 110 and standard deviation = 5
Now we need to find
P (x > 112)
As distribution is normal we can convert x to z
<h3>Therefore, So the correct answer is 0.3446</h3>
Answer:
ITSS C!!!!!!!!!!!!!!!
Step-by-step explanation:
Answer:
x= 2, 1/2
Step-by-step explanation:
x= b±√b²-4ac/2a
x = [5±√(-5)²-4·(2·2)]/2·2
x = (5±3)/4
x= 2, 1/2
