Suppose the length of steel rods produced by a machine is approximately normally distributed. a random sample of 16 rods were collected and measured, and a sample mean of ỹ = 1.3 m and a sample standard deviation of s = 0.4 m were recorded. (a) what is the probability that the average length of steel rods produced by this machine (i. e., population mean) exceeds 1.5 m?

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
