2. the following is a sample of unemployment rates (in percentage points) in the us sampled from the period 1990-2004. 4.2, 4.7, 5.4, 5.8, 4.9 compute the sample mean, x and standard deviation, s using the formula method. (round your answers to one decimal place). [note: you can only use the calculator method to check your answer]. 23. using question 22, find the following: a. in what range does the empirical rule predict that approximately 95% of the unemployment rates will fall? b. what is the actual percentage of the employment rates fall in the range predicted in part (a) c. which gives the more accurate prediction of the percentage in part (b), chebyshev’s rule or the empirical rule? [give reason(s)]

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
