Numerator & Denominator for 0.96 as a Fraction
0.96 = 0 96/100
numerator/denominator = 96/100
Level of Precision for 0.96 = 0 96/100
Customize the level of precision to break 0.96 down further into a fraction. Note that the last digit after the precision point is rounded up or down accordingly.
With that in mind decimal 0.96 with a precision point of two has the following fractional breakdown:
96/100
= 48/50
= 24/25

Step-by-step explanation:
Given that the random variable x represents the number of phone calls an author receives in a day
Poisson distribution is a discrete distribution with random variable countable.
Here no of calls cannot be in fraction or decimal.
Also given that X is Poisson with mean = 7.6
X is discrete since no of phone calls can take values as 1,2,3....
X can take any value from 0 to infinity.
x=3.2 is not possible since 3.2 calls does not exist.
Answer:
the possible values of x is 0,1,2,3...

So as per given data Sam's age is 5/3 times of Hank's age
so x = 5/3 * y
3x = 5y --> equation 1
and also sum of their ages is 24
so, x + y = 24
we need to find Hank's age (y)
so x = 24 - y
Now replace x value in equation 1
3(24-y) = 5y
72-3y = 5y
72 = 3y+5y
8y= 72
y= 72/8
y = 9 years.
So the Hank's age is 9 years

a) A balloon has a circumference of 28 in. Use the circumference to approximate the volume of the balloon to the nearest cubic inch.
or
b) A balloon has a circumference of 28 in. Use the circumference to approximate the surface area of the balloon to the nearest square inch.
case a)
we know that
circumference=2*pi*r
clear variable r
r=circumference/(2*pi)
circumference=28 in
r=28/(2*pi)----> r=4.46 in
volume of a balloon=(4/3)*pi*r³-----> (4/3)*pi*4.46³----> 371.61 in³
Volume=372 in³
the answer is
372 in³
case b)
we know that
circumference=2*pi*r
clear variable r
r=circumference/(2*pi)
circumference=28 in
r=28/(2*pi)----> r=4.46 in
surface area of a balloon=4*pi*r²-----> 4*pi*4.46²---> 249.83 in²
Surface area=249.83 in²-------> 250 in²
the answer is
250 in²
