Summing all the frequencies, we deduce the total number of trials:

4+8+36+20+12=80

Knowing how many trials have been done, we deduce the probability of each outcome by dividing its frequency and the number of trials:

P(0)=\dfrac{4}{80}=\dfrac{1}{20},\quad P(1)=\dfrac{8}{80}=\dfrac{1}{10},\ldots

Convert these fractions to numbers, and drag each slider where it is supposed to be.

Fox example, we have

P(0)=\dfrac{1}{20} = 0.05

So, you'll have to drag the first slider up to 0.05, and so on.

Find the common difference for the arithmetic sequence. 1.7, 2.7, 3.7 4.7.....
Anni [7]

Answer:

Step-by-step explanation:

You do not need to where the formula comes from but, just for fun, here’s a hint

To add up the numbers 1 to 10

Write out the numbers

1 2 3 4 5 6 7 8 9 10

Write them backwards

10 9 8 7 6 5 4 3 2 1

Add up both lists

11  11  11  11  11  11  11  11  11 11

This is 10 × 11 = 110

But this is twice the sum as two lots were added together

So the sum of the numbers 1 to 10 is 110 ÷ 2 = 55

Step-by-step explanation:

Hey, this question concerns the inscribed angle theorem.

The formula for this is:

∠ABC = 2*∠ADC

∴ ∠ABC = 40°

For proof, look up 'inscribed angle theorem (or central angle theorem)' on YT.
