Just look at the percentages and make them into fractions. You can think about it like money. 50 cents is half of a dollar, so %50 is 1/2. for the decimals, you just take the percent and put a decimal point in front of the answer, so 28% is .28, 50% is .50, 18% is .18. For fraction to decimals, you could just put 1 divided by 4 into a calculator and it will tell you .25, which is the decimal, and 25 cents is one fourth of a dollar, so it works out.
Hope this helps! Let me know if you have any more questions!
Answer:

For this case the reliability of the sytem would be given by:

R1= 0.95, R2 =0.95, R3= 0.5, R4 = 0.79 , R5 = 0.6
And replacing we got:

Step-by-step explanation:
We can assume that the system work in series
If we have in general n units the reliability of the system is the probability that unit 1 succeeds and unit 2 succeeds and all of the other units in the system succeed. fror n units must succeed for the system to succeed. The reliability of the system is then given by:

For this case the reliability of the sytem would be given by:

R1= 0.95, R2 =0.95, R3= 0.5, R4 = 0.79 , R5 = 0.6
And replacing we got:

Answer:
Correct answer: r = 5%
Step-by-step explanation:
Given:
L = 4,500 Loan
t = 4 years time to repay
I = 900 Interest
r = ? simple interest rate
The formula for calculating simple interest is:
I = (L · r · t) / 100
r = ( I · 100) / L · t
r = (900 · 100) / 4,500 · 4 = 90,000 / 18,000 = 5 %
r = 5 %

The area of a trapezoid can be found by the formula:
A = [(B + b) × h] / 2
where:
B = major base = 36 in
b = minor base = 30 in
h = height = 24 in
Therefore, with the given data you can calculate the area by applying the formula:
<span>A = [(36 + 30) × 24] / 2
= [66 </span><span>× 24] / 2
= 792 in</span>²
Hence, the area of the trapezoid is 792 in<span>².</span>
