Answer:
0.3707
Step-by-step explanation:
Mean length = 30.05 inches
Standard deviation = 0.3 inches
We are supposed to find the probability that the average length of a steel sheet from a sample of 9 units is more than 29.95 inches long
Formula :
x= 29.95
Substitute the values :
Refer the z table for p value
p value = 0.3707
So, the probability that the average length of a steel sheet from a sample of 9 units is more than 29.95 inches long is 0.3707
Answer:
(a) If f and t are both even functions, product ft is even.
(b) If f and t are both odd functions, product ft is even.
(c) If f is even and t is odd, product ft is odd.
Step-by-step explanation:
Even function: A function g(x) is called an even function if
Odd function: A function g(x) is called an odd function if
(a)
Let f and t are both even functions, then
The product of both functions is
The function ft is even function.
(b)
Let f and t are both odd functions, then
The product of both functions is
The function ft is even function.
(c)
Let f is even and t odd function, then
The product of both functions is
The function ft is odd function.
