The governments in two countries, Statland and Statopia, are proposing to change their national currencies to the Statto. The pr
oportion of support for such a change within the population in Statland and Statopia are modelled by random variables X and Y respectively. It is thought that the joint density function for the two variables is of the formf(x,y)=(2/5)*(2x+3y) for 0f(x,y)=0 elsewherePart b) the probability that changing to the Statto has the support of more than half the population in each country. 15/30Part c) the marginal density of the support for the Statto in Statland evaluated at the point X=1/2. is 1Part d) the marginal density of the support for the Statto in Statland evaluated at the point Y=1/2. is 1Part e) Find the conditional density of the support for the Statto in Statland given the support of a third of the population in Statopia. Evaluate this density at the point X=1/2
Four oranges cost 90 cents, an orange costs 90/4 cents, which is around 22.5 cents. Multiply this by 36 to get the cost of 3 dozen oranges, so 22.5 times 36 is 810, 810 cents, or 8.10 dollars.
The starting height of the tree was 1.85 meters. To find the number of meters the tree grew, you would subtract the current height from the previous height. 5.30-1.85=x. This equation is the same as 1.85 + x = 5.30 if you switch the 5.30 and x.
If it is 50 pages in an hour, half an hour would be 25 pages, and if it is 40 pages in an hour it would be 20 pages in half an hour, the answer is 5 pages more in half hour
because the real numbers did not have zero. the real number are starting from positive 1 to positive infinity number. If we suppose a = 1, b = 2, c = 3 abc / abc = 1.
