I don't get it can u help me??

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!

there has to be at least one operating path. Once a component fails on a path, that path is no longer operating. The reliability
Eva8 [605]

Answer:

R = P(R_1) P(R_2|R_1) P(R_3|R_2)*....*P(R_n |R_1,..., R_{n-1}

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

R= \prod_{i=1}^n R_i

R1= 0.95, R2 =0.95, R3= 0.5, R4 = 0.79 , R5 = 0.6

And replacing we got:

R = 0.95*0.95*0.5*0.79*0.6= 0.21389

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:

R = P(R_1) P(R_2|R_1) P(R_3|R_2)*....*P(R_n |R_1,..., R_{n-1}

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

R= \prod_{i=1}^n R_i

R1= 0.95, R2 =0.95, R3= 0.5, R4 = 0.79 , R5 = 0.6

And replacing we got:

R = 0.95*0.95*0.5*0.79*0.6= 0.21389

Samantha asked for a loan from the bank of 4,500 plans to repay it in 4 years Samantha will have to repay it 900 of interest wha
Scrat [10]

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 %

God is with you!!!

Andrew wants to make a decorative placemat in the shape of an isosceles trapezoid with a height of 24 inches and bases of 36 inc
OlgaM077 [116]
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>
