Acoin of questionable fairness is tossed 10 times per set of trials for two sets of trials. the outcomes are ththththht and ttthtthtth (t = tails; h = heads). which model can you most likely rule out on the basis of this simulation?
a. the probability of heads is 40%.
b. the probability of heads is 30%.
c. the probability of heads is 35%
d. the probability of heads is 70%

Therefore, The correct option is A. The probability of heads is 40%  

Step-by-step explanation:

First set of trials : THTHTHTHHT ( T = Tails ; H = Heads)

Number of heads = 5

Number of outcomes = 10

Second set of trials : TTTHTTHTTH

Number of heads = 3

Number of outcomes = 10

Now, Total number of heads in the two tosses of the coin = 5 + 3 = 8

Total number of outcomes in the two tosses of the coin = 10 + 10 = 20

Therefore, The correct option is A. The probability of heads is 40%

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
