The experimental probability is 6% higher than the theoretical probability
Aliun [14]3 years ago
3 0

Answer:  Third option is correct.

Step-by-step explanation:

Since we have given that

Number of heads = 56

Number of tails = 44

Total number of flips = 100

So, Probability of getting head is given by

\dfrac{56}{100}=0.56

Theoretical probability of getting head is given by

\dfrac{50}{100}=0.50

There is a difference of

0.56-0.50=0.06 = 6%

Hence, the experimental probability is 6% higher than the theoretical probability.

Therefore, Third option is correct.

Andrew is paid $4 per hour for the first 30 hours he works each week. He makes $5 per hour for each hour he works over 30 hours
klasskru [66]

Answer:

If Andrew works for 30 for $4 he will have a total wage of 30×4=$120

And gets additional $5for every hr worked beyond 30hrs in that week

So he gets a total of 5(x-30)

So if he works for 40hrs he gets a total wage of

5(40-30)=50

120+50=$170

If he works for 50 hours he gets Total wage of

5(50-30)=100

120+100=$220

Please answer correctly !!!! Will mark brainliest !!!!!!!!!!!!!!
Murrr4er [49]

Step-by-step explanation:

Adding 10 to both sides of the original equation gets us q = 6(r + 1) + 10. Since q is equal to h(r), we get h(r) = 6(r + 1) + 10 = 6r + 16.
