The high temperature x (in degrees centigrade) during winter-time in washington d. c. varies according to the normal distribution with mean 21 and standard deviation 10.the probability is 0.3 that a randomly selected winter day in washington d. c. will have a high temperature greater than centigrade. which number completes the sentence correctly

A suitable probability calculator can tell you the desired temperature is about 26.2 °C.

_____

The invNorm function on this calculator gives the x-value below which the probability distribution has the given area. Since you want the x-value for the area above being 0.3, the area below that x-value will be 1-0.3 = 0.7.

the answer is true.

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
