Answer:
The number of Apples did Ravi have at first is 125 .
Step-by-step explanation:
Let the number of Apples did Ravi have at first = x
The Apples which is sold by Ravi = 
of x
So, remainder now = x - of x = 
of x
The apples given to his friend = 
of x
I.e The apples given to his friend = 
of x
Now, The remaining Apples did Ravi have = 50
∴ According to question
of x - of x = 60
Or, 
of x = 60
Or, 
of x = 60
∴ x = 
= 125
Hence The number of Apples did Ravi have at first is 125 . Answer
5 cupcakes = $7.5
18 cupcakes = $27
Answer:
a) 0.0821
b) 0.0111
c) 0.0041
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
In which 
is the decay parameter.
The probability that x is lower or equal to a is given by:
Which has the following solution:
Either it lasts more 5 years or less, or it survives more than 5 years. The sum of the probabilities of these events is decimal 1. So
In all 3 cases, we want P(X > 5). So
In which
(a) lambda=.5
(b) lambda=0.9
(c) lambda=1.1
Answer:
32 m
Step-by-step explanation:
The distance across the river is give as x and we are interested in finding the value of x.
Both the triangles are similar by AA Postulate.
Therefore,
20/x = 10/16 (by c.s.s.t.)
2/x = 1/16
x = 16*2
x = 32 m
That would be 1
I hope I've helped!
