A coin is weighted so that the probability of getting heads is suppose you toss this coin 15 times. Let X represent the number of heads. What are the mean and standard deviation of X?
OW, = 0.67, 0, = 0.88
O x = 7.5.0. = 2.33
O wx = 7.5, 0,=3.33
O wx = 10, 0, = 1.83

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

ok

step-by-step explanation:

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
