Aflorist determines the probabilities for the number of flower arrangements they deliver each day. x 19 20 21 22 23 p ( x ) 0.24 0.21 0.32 0.13 0.10 find the mean, variance, and standard deviation of the distribution rounded to 4 decimal places. mean = variance = standard deviation = approximately how many arrangements should the florist expect to deliver each week, rounded to the nearest whole number?

the answer is 21%.

13664

step-by-step explanation:

=cross multiply

=100 x = 13664

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.

114 plus 113 times 2 and 114 times 3
