Answer:
0.1225
Step-by-step explanation:
Given
Number of Machines = 20
Defective Machines = 7
Required
Probability that two selected (with replacement) are defective.
The first step is to define an event that a machine will be defective.
Let M represent the selected machine sis defective.
P(M) = 7/20
Provided that the two selected machines are replaced;
The probability is calculated as thus
P(Both) = P(First Defect) * P(Second Defect)
From tge question, we understand that each selection is replaced before another selection is made.
This means that the probability of first selection and the probability of second selection are independent.
And as such;
P(First Defect) = P (Second Defect) = P(M) = 7/20
So;
P(Both) = P(First Defect) * P(Second Defect)
PBoth) = 7/20 * 7/20
P(Both) = 49/400
P(Both) = 0.1225
Hence, the probability that both choices will be defective machines is 0.1225
3 x 4 is equal to 12 I think that’s your answer
R=Number of rabbits
y=Years that have passed by { y ≥ 0 }
R=f(y) --> R is a function of y.
---------------------------------------------
Note that when:
y=0, R=4 ---> Point: (0, 4)
y=1, R=8 ---> Point (1, 8)
y=2, R=16 ---> Point (2, 16)
y=3, R=32 ---> Point (3, 32)
y=4, R=64 ---> Point (4, 64)
--------------------------------------------
So the equation you want is going to form a curved graph.
That equation is:

<em>*You can test out this function on any decent graphing software.</em>
Answer:
-3/2
Step-by-step explanation:
(Y2-Y1)/(X2-X1)
(-4 - 5) / (4 - (-2))
-9 / 6
Simplified: -3/2
3.01 is the decimal notation for 3 1/100. You keep the three in the ones place. 1/100 is a decimal. If you use long division or a calculator, you can see that 1/100 is 0.01.
