Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.6. (Round your answers to four decimal places.) A button hyperlink to the SALT program that reads: Use SALT. (a) If the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51

d

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

37 = ending with 7

56 = ending with 6

133 = ending with

unit's digit in the cube..7
