The compressive strength of samples of cement can be modeled by a normal distribution with a mean of 6000 kilograms per square centimeter and a standard deviation of 100 kilograms per square centimeter. (a) what is the probability that a samples strength is less than 6250 kilograms per square centimeter? (b) what is the probability that a samples strength is between 5800 and 5900 kilograms per square centimeter? (c) what strength is exceeded by 95% of the samples?

but there’s no any figure there!

true

step-by-step explanation:

it is more then likely a review to you prepare for an upcomign test or quiz

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
