A random sample of size n1 = 13 is selected from a normal population with a mean of 76 and a standard deviation of 7. A second random sample of size n2 = 10 is taken from another normal population with mean 68 and standard deviation 14. Let and be the two sample means. Find: (a) The probability that exceeds 3. (b) The probability that 4.5 5.5.

The length of the line segment joining the midpoints of sides ab and bc of the parallelogram abcd is 10. find the length of diagnol ac

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
