Question

A group of students toss a coin as part of an experiment.they toss 2763heads and 1589 tails. How many times did they toss a coin? they tossed a coin _ times.​

Answer 1

Answer:

The tossed a coin 4352 times.

Step-by-step explanation:

Given, a group of students toss a coin for an experiment.

And they toss 2763 heads and 1589 tails.

So, number of heads $= 2763$ and number of tails $= 1589$

We know,

Total number of toss = Total number of heads + Total number of tails.

So required total number of toss

$= 2763 + 1589 \\ = 4352$

This is a problem of Algebra.

Some important Algebra formulas,

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
