Ratio in which 180 should be divided is 4:5:9
firstly we need to find the total number of portions 
this we can find by adding all the numbers making up the ratio 
4 + 5 + 9 = 18
180 is made of 18 portions 
size of 1 portion = 180 / 18 = 10
when dividing 180 into the respective ratio 4:5:9 the portions are as follows
4 x 10 = 40
5 x 10 = 50
9 x 10 = 90
therefore when we divide 180 in the ratio 4:5:9
the answer we get is
40 :50: 90

charle [14.2K]

Answer:

P (A ║ B)  = 1.98 %

Step-by-step explanation:

Bayes´ Theorem  express

P (A ║ B)  =  P(A) * P( B ║ A) / P(B)

Now we identify

Event A  person infected with a virus. Probability of being infected by a virus is  P/A)  0.001

Event B  the test was positive. Probability of test positive  P(B)  = 0,05

Probability of  P ( B║ A)  is the porbability of test positive given that is infected   = 0.99

Then by subtitution in a general equation of the theorem we have

P (A ║ B)  =  0.001*0.99/ 0.05

P (A ║ B)  =  0.0198          P (A ║ B)  = 1.98 %

Answer: $6, 720

Step-by-step explanation:

Formular for simple interest =P×R×T

where;

P= 6000

R= 3% = 0.03

T= 4 years

$6000 × 0.03 × 4

= $720

The total amount to be paid back at the end of time will be

$6,000 + $720

=$6, 720
