Consider flipping a fair coin. suppose that you flip the coin repeatedly until you get a heads then a tails consecutively, in that order. for example, some flipping sequences are: ht, t, and hhht. let x be the random variable for the number of flips completed. find e[x] and var(x). you may use wolfram alpha or another tool to compute the value of any infinite sums.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

x=half

step-by-step explanation:

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
