Answer:

Step-by-step explanation:

Of the twenty times in this experiment the following are prime (3,5,2,7,3,7,2,2,7,3,3,5) or 12 of the twenty

12/20 = 6/10  = 60%

So 60% is the experimental probabilty.

The theoretical probability given that there are four prime numbers (2,3,5,7) out of 8 on the dice should be 50%  because 1/2 of the numbers are prime.

The experimental probability is 10% more than the theoretical probability

60% - 50% = 10%

Answer:

Step-by-step explanation:

Theoretical odds of rolling an odd number is 4/8 = 50%

The experimental probability of rolling an odd number is 9/15 = 60 %

which is (60 - 50) / 50 = 20% more than the theoretical probability.

This is an imprecisely worded question as 60% is 10% more than 50%

but the number of actual odd numbers rolled is 20% more than was theoretically expected.  

Expected 7.5 odd numbers

1.20(7.5) = 9 actual odd numbers

Not sure which answer is sought.

A dinner plate has a circumference of 106.76 cm. What is the area of the dinner plate? Use = 3.14.
Sphinxa [80]
C=2pr,  r=c/(2p)

a=pr^2, using r found above we get:

a=p(c^2/(4p^2))

a=(c^2)/(4p), since c=106.76 and we approximate pi as 3.14

a=(106.76^2)/(4*3.14)

a=11612.2176/12.56 cm^2

a≈924.54 cm^2  (to nearest one-hundredth of a square cm)

What is the GCF for each set of numbers 12 and 20
Likurg_2 [28]
4 is the GCF.

Explanation:
4x3=12
4x5=20
5 Isn’t a factor of 12, and 6 isn’t a factor of 20. Each number above doesn’t work, so the greatest common factor of the numbers 12 and 20 must be 4.
