Answer:
x = 10
Step-by-step explanation:
We know that the sum of angles in a triangle is equal to 180 degrees;
This means that
71+50+(6x-1) = 180; now that you have an algebraic expression, you can solve for x.
71+49+6x=180
120+6x = 180
6x = 60
x = 10
Answer:
The overall reliability of the system is 99.9952%
Step-by-step explanation:
Probability of the system not working:
None working, the first with 2% probability of not working(as it has 98% probability of working), the second with 4% and the third with 6%. So
0.02*0.04*0.06 = 0.000048
Probability of the system working:
1 subtracted by the probability of the systme not working.
1 - 0.000048 = 0.999952
0.999952*100% = 99.9952%
The overall reliability of the system is 99.9952%
If a number is 5679, expanded form is 5000+600+70+9

Answer:
4,000 enroll
Step-by-step explanation:
If 20,000 students apply and the university only accepts 40%, the university accepted 8,000 students.
How many actually enrolled?
Of those accepted students (8,000), 50% enroll.
8,000 / 2 OR 8,000 x 0.50 = 4,000 students actually enroll.
