Alanna wants to fence-in a rectangular dog pen in her backyard. She has 48 metres of fencing.

What are the dimensions of the largest dog pen Alanna can enclose if:

a) Alanna fences all four sides?

b) Alanna fences three sides of the pen and uses her house as the fourth side?

If 90° < θ < 180° and cotθ = -1/3, then cscθ =

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

What is the solution to the equation? k/6.4=8.7 2.3 5.568 15.1 55.68
