A coin 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%

Answers

Answer:

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

\text{So, Probability of heads = }(8)/(20)* 100=40\%

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

What is the difference of the two polynomials?(7y^2 + 6xy) – (–2xy + 3)

A.) 7y^2 + 4xy – 3

B.) 7y^2 + 8xy – 3

C.) 7y^2 + 4xy + 3

D.) 7y^2 + 8xy + 3

Answers

Answer:

B) 7y² + 8xy - 3 .

Step-by-step explanation:

Given  : (7y² + 6xy) – (–2xy + 3).

To find : What is the difference of the two polynomials.

Solution : We have given

(7y² + 6xy) – (–2xy + 3).

Removing the pantheists

(7y² + 6xy) + 2xy - 3).

Combine like terms

7y² + 8xy - 3 .

Therefore, B) 7y² + 8xy - 3 .
the answer to that question is B.
