Approximately 10% of all people are left-handed ("11 little-known facts," 2013). Consider a grouping of fifteen people. a.) State the random variable. X = b.) Show that this is a binomial. Find the probability that c.) None are left-handed. d.) Seven are left-handed. e.) At least two are left-handed. f.) At most three are left-handed. g.) At least seven are left-handed. h.) Find the mean of X. i.) Find the variance of X. j.) Find the Standard deviation of X.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

step-by-step explanation:

10 b/c 5*2 =10

step-by-step explanation:

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
