A researcher records the time (in seconds) that participants arrive late for a scheduled research study. Assuming these data are normally distributed, which measure of central tendency is most appropriate to describe these data?
Answers
Answer:MEAN
Step-by-step explanation:Mean is a measure of central tendency it is sometimes referred to as a average of a set of numbers.The mean can also be described as the central value of a discrete set of values or numbers, the formula for Arithmetic mean is the sum of the values or number divided by the number of values or outcome.
Normal distribution is a statistical term which describes a set of values or numbers whose symmetric, unimodal, and asymptotic, and the mean, median, and mode are all equal.

The first one is not a function because domain 0 has two different ranges, 3 and 4 ⇒ (0,3)(0,4)
The second one is a function
The third one is not a function because domain 2 has two different ranges, 6 and 0 ⇒ (2,6)(2,0)
The fourth one is not a function because domain 6 has two different ranges, 2 and 4 ⇒ (6,2)(6,4)
Solve for b: A=6b
Solve for b : A=1/2bh

Answer:
see explanation
Step-by-step explanation:
A = 6b ( divide both sides by 6 )
= b
--------------------------------------
A = bh ( multiply both sides by 2 to clear the fraction )
2A = bh ( divide both sides by h )
= b

remember that 45-45-90 triangle has sides of x,x and x√2
(legs are measure x and hypotonuse=x√2)
the legs are equal and are also the base and height
find the legs (x=leg)
hypotonuse=24
24=x√2
divide both sides by √2
24/(√2)=leg=base=height
volume=1/2 times base times heigth
V=1/2 times (24/√2) times (24/√2)
V=1/2 times (576/2)
V=576/4
V=144 units^2

where n = 1 ; n = 2 ; n = 3
3(n) - 1 = 3(1) - 1 = 3 - 1 = 2
3(n) - 1 = 3(2) - 1 = 6 - 1 = 5
3(n) - 1 = 3(3) - 1 = 9 - 1 = 8
