You are correct

for example f(1) = 3

and   f(2) = f(2-1) - 2

= f(1) - 2

= 3 - 2 = 1

f(n) = f(n-1) - 2

f(1) = 3        eq1

f(2) = f(2-1) - 2

     = f(1) - 2.   put value from eq1 here

     = 3 - 2

     = 1

f(3) = f ( 3 - 1 ) - 2

     = f(2) - 2

     = 1 - 2

     = -1

f(4) = f( 4 -1 ) - 2

     = f( 3 ) - 2

     =  -1 - 2

     = -3

Suppose a batch of metal shafts produced in a manufacturing company have a standard deviation of 1.5 and a mean diameter of 205
lawyer [7]

Answer:

the probability is 0.0750

Step-by-step explanation:

The computation of the probability is shown below;

The mean of x is

= 1.5 ÷ √79

= 0.1688

Now the probability is

= P(Z < -0.3 ÷ 0.1688) + P(\bar{x} > 0.3 ÷ 0.1688)

= P(Z < -1.78) + P(Z > 1.78)

= P(Z < -1.78) + 1 - P(Z < 1.78

= 0.0375 + 1 - 0.9625

= 0.0750

hence, the probability is 0.0750

I'm not usually good at these questions but you can get a calculator that does weight multiplied by units.
so with your question it would be :

1.2 ounces x (48 units)
=  57.6 ounces




57.6 ounces
