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.

10+8+7(-10)-(-1)
Elina [12.6K]

Answer:

-51

Step-by-step explanation:

Let's do order of operations.

10+8-70-(-1)     <- We did negative 7 times 10.

18-70-(-1)    <- We did 10 plus 18.

-52-(-1)     <- We did 18 minus 70

When you open the () we get:

-52--1

Negative minus a negative equals a positive.

-52+1=

-51

At the market, 8 apples cost $4dollar. How much do 9 apples cost?
Lorico [155]

Answer: $4.50 for 9 apples

Step-by-step explanation: To find out how much it is for 1 apple, we need to find the unit price of 1 apple which is the cost per apple.

Since we know that it costs $4 for 8 apples, to find the cost for 1 apple, we need to divide 8 into $4 or 4 divided by 8 which is 0.5 of 50 cents per apple.

Since we know that it costs 50 cents per apple, to find the cost for 9 apples, we will need to multiply .50 by 9.

(.50) (9) = 4.50

Therefore, it will cost $4.50 for 9 apples.
