No, this is not normal

This is a binomial distribution. Use BINS to determine if this is binomial.
B - binary?
I - independent?
N - number of trials
S - probability of success

B - yes, 3 or not a 3
I - yes, past rolls do not impact future rolls
N - 20 trials
S - prob success 1/6

Use binompdf on your calculator to find out the probability. To access, 2nd —> vars —> binompdf

Binompdf(20 (trials), 1/6 (p), 11 (x)) = 8.97x10^-5

The probability to roll a 3 11 times is .0000897. The chances are very low, making this not normal.

Paloma can run the 100-meter dash in 16 1/5 seconds. Savannah's best time is 19.8 seconds. How much faster is Paloma than Savann

Anastaziya [24]

16 and 1/5 is equal to 16.2
So 19.8 subtract 16.2 is equal to 3.6
Savannah is 3.6 or 3 and 3/5 seconds faster than Paloma.

The Petrified Forest National Park in Arizona recently expanded their boundaries by 93,533 acres. The original acreage was 125,0

leonid [27]

Answer: The new acreage of the park is 218,533.

Step-by-step explanation:

Since we have given that

Original acreage = 125,000

Expanded boundary by = 93,533 acres

We need to find the new acreage of the park.

so,we will use

$New\ acreage=Original\ acreage+Expanded\\\\New\ acreage=125000+93533\\\\New\ acreage=218,533$

Hence, The new acreage of the park is 218,533.
