When a coin is tossed 20 times, it lands on heads 5 times. How does the experimental probability differ from the theoretical probability?

Answers

Answer 1

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Number of tosses / trials = 20

Number of heads = 5

The experimental probability = the actual output of am event when an experiment or test is carried out :

Experimental probability = number of occuences / number of trials

That is :

P(head) = 5 / 20 = 1/4

Theoretical probability could be regarded as the expected output of an event based on the mathematical calculation :

Required outcome / Total possible outcomes

Theoretical probability P(head) in a toss = 1/2

Step-by-step explanation:

College Board

The probability that the selected student will be be in grade 10 given that the student ordered French fries is 71/245

P(French fries n grade 10) = 71 Total who ordered French fries = 248

The conditional probability can be defines thus :

Number in grade 10 who ordered French fries = 71

Total number who ordered French fries = 245

Hence,

P(grade 10 | French fries) = 71/245

If tax was 8.25% on the $220 total for the items purchased at Target, what was the total cost of the items including tax?

Answers

Answer:

$238.15

Step-by-step explanation:

8.25% = 8.25/100 or 0.0825

Multiply 0.0825 and 220 to get $18.15. That's how much the tax is.

Add 220 and 18.15 to get $238.15

Answer:

$238.15

Step-by-step explanation:

To find the total cost of the items including tax you will need to multiply the cost of the items by the decimal form of 8.25%.

The decimal form of 8.25% is .0825. When turning percents to the decimal form we move the decimal two places to the left.

Now we multiply!

(220)(.0825) = 18.15

Now add 18.15 onto the 220 to find the total cost including tax:

220 + 18.15 = 238.15

Therefore, the total cost of the items including tax is $238.15.

Backyard area = 18 x 22 = 396ft²

Area of a circle = pi x radius² (radius = diameter/2)

one number is two more than triple a second number. Their sum is 30. what is the smaller number

Answers

Answer:

7

Step-by-step explanation:

We can solve this problem by making an equation.

Let x represent the second number

3x + 2 will be the first number because it is 2 more than triple x

This makes our equation:

3x + 2 + x = 30

Combine like terms

4x + 2 = 30

Subtract 2 from both sides

4x = 28

Divide both sides by 4

x = 7

The smaller number aka the second number is 7
