What's the difference between theoretical probability and experimental probability

Mathematics
1 answer:
NeX [460]3 years ago

Theoretical probability is the likelihood of a certain event occurring calculated based on all the possible outcomes. (Theorizing about the probability of a certain occurrence)

Experimental probability is the likelihood of a certain event occurring calculated by performing trials of an activity and recording the number of times an event occurs, then dividing the total number of even occurrences by total number of trials. (Experimenting to find probability of a certain occurrence)

Shaila and her sister Sarah are babysitting three Kids for 5 hours. If the parents pay $2.50 per hour for each kid,how much will
mart [117]

3 times 5 times 2.5 = $37.5

3 x 5 =15

15 x 2.5 =37.5

37.5 x 2 = 75 for both of them

I don't know if this is right or not, but that's how I would solve it!

Plz I need help bad!
gtnhenbr [62]

Answer:

72 bowls with 12 cups of cream

Step-by-step explanation:

First, I want to point out that the information, “3 pots of soup” is useless. So disregard that.

1/6 cups of cream for every bowl. That means, the assistant can prepare 6 bowls with one cup of cream.

1/6–bowl 1

1/6–bowl 2

1/6–bowl 3

1/6–bowl 4

1/6–bowl 5

1/6–bowl 6

At this point, 6 bowls are prepared. Add up all the cream that was used to make these 6 bowls.

1/6+1/6+1/6+1/6+1/6+1/6 = 6/6

Since 6/6=1, 1 whole cup of cream makes 6 bowls. That means 12 whole cups will make 12 x 6 = 72 bowls.

Hope this helps!

The vertex of the parabola below is at the point (4, -1). Which of the equations below could be the one for this parabola?
kari74 [83]
One possible equation for this quadratic would be 

y=(x-4)²-1.  This is vertex form:  y=a(x-h)²+k, where (h, k) is the vertex.

However, this is not the only possible equation.  There could be multiple values for a, in front of the parentheses, that we don't know about from the information we are given.

We can also write this equation in standard form (y=ax²+bx+c).  First write the squared binomial as the product of two binomials:
y=(x-4)(x-4)-1

Multiply the binomials:
y=x*x-4*x-4*x-4(-4)-1
 = x²-4x-4x--16-1
 = x²-8x+16-1
 = x²-8x+15

Again, this would change depending on what the value of a is in the functoin.

John runs the same number of kilometres each day.write an expression to represent the number of kilometre john ran in june last
love history [14]

An algebraic expression to represent the number of kilometres John ran in June month last year is 30a.

Given that, John runs the same number of kilometres each day.

We need to find an algebraic expression to represent the number of kilometres John ran in June month last year

<h3>What is an algebraic expression?</h3>

An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc.

Let us assume that john is running 'a' kilometres per day.

We know that June month composed of total 30 days

So the algebraic expression for the number of kilometres John ran in June last year = Number of kilometres running per day × Number of days in the month of June

=a × 30=30a

Therefore, an algebraic expression to represent the number of kilometres John ran in June month last year is 30a.
