Can anyone plz explain the permutation formula in math? and plz make it simple because I'm just a 7th grade student

Answer:

To calculate permutations, we use the equation nPr, where n is the total number of choices and r is the amount of items being selected. To solve this equation, use the equation nPr = n! / (n - r)!.

The circle graph shows the percentage of time Jacob spent on homework in each subject last week.Time Spent on Homework12.5%25%ar

Goshia [24]

We are given a circle graph that shows the time spent on homework last week.

Jacob spent a total of 16 hours doing homework.

The time spent on doing science homework is given by

$\begin{gathered} t_{\text{science}}=25\%\: of\: 16 \\ t_{\text{science}}=\frac{25}{100}\: \times\: 16=4\: \text{hours} \end{gathered}$

The time spent on doing band practice is given by

$\begin{gathered} t_{\text{band}}=12.5\%\: of\: 16 \\ t_{\text{science}}=\frac{12.5}{100}\: \times\: 16=2\: \text{hours} \end{gathered}$

The difference between the time spent on science homework and band practice is

$difference=t_{\text{science}}-t_{\text{band}}=4-2=2\: \text{hours}$

Therefore, Jacob spent 2 more hours on science homework than band practice.

Is the square root of 2 between 1.3 and 1.4

vesna_86 [32]

Well I don't know. Let's see . . .

The square of 1.3 is 1.69 .
The square of 1.4 is 1.96 .

' 2 ' is not between 1.69 and 1.96 , so the square root of 2
is not between 1.3 and 1.4 .

(The square root of 2 is 1.414.... . That's a little bit past 1.4 .)
