HELP!! Alinn flipped a coin 20 times. The coin landed on heads 12 times and tails 8 times.
a. Based on the results, what is the experimental probability of the coin landing heads up?
b. What is the theoretical probability of the coin landing heads up?

 It is 12/20 and 8/20 so heads has a higher chance

Step-by-step explanation:

The experimental probability is given by the results of the experiment.

The coin landed heads up 12 out of 20 times. Divide the amount of times it landed heads up by the amount of times you flipped the coin

12 divided by 20=0.6

Multiply this decimal by 100 to get the percentage:

0.6 times 100=60

The experimental probability of the coin landing heads up is 12/20, or 3/5, or 60%.

The theoretical probability is given by the chances of landing the coin heads up.

There are two outcomes: the coin landing heads up, and the coin landing tails up. Out of two outcomes, you want one.

Theoretical probability is given by the amount of wanted possibilities over the total possibilities. You want 1 out of 2 to occur, so the theoretical probability is 1/2, or 50%.

Step-by-step explanation:

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

answe: it will take 4.5 hours for naomi and clair to paint an equal number of square feet
