Dennis wants to change up his workout today, and he decides to flip a coin to determine his activity. if the coin lands on heads, dennis will do push-ups for one minute. if the coin lands on tails, dennis will do sit-ups for one minute. he flips the coin a total of 30 times, and his results are shown below. flip 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 result h t t h t h h h t t h t h t h flip 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 result t t h t h t t h t t h t t t t what is the probability that a randomly selected minute from dennis' workout would consist of sit-ups?

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

one set of data has more variation than the other. hope this !
