Solve for p.<br> i = prt<br><br> p = i-rt<br> p = (rt)/i<br> p = i/(rt)
andrezito [222]

Answer:

\sf p = \dfrac{i}{rt}

Step-by-step explanation:

Solve for p:

\longrightarrow i = prt

i = prt is equivalent to prt = i:

\longrightarrow prt = i

Divide both sides by rt:

\longrightarrow \sf \dfrac{prt}{rt} = \dfrac{i}{rt}

\sf \dfrac{prt}{rt} = p:

\longrightarrow \sf p = \dfrac{i}{rt}

Urgent please!!! I really don’t understand it, tysm to anyone who can answer thissss :))))

Given:

The frequency distribution table.

To find:

The mean average score on a test.

Solution:

The frequency distribution table is

Marks (x_i)                   Frequency(f_i)                  f_ix_i

     x                                     a                               xa

     y                                     b                               yb

     z                                     c                               zc

  Sum                              a+b+c                          xa+yb+zc

Now, the mean average score on the test is

Mean=\dfrac{\sum f_ix_i}{\sum f_i}

Mean=\dfrac{xa+yb+zc}{a+b+c}

Therefore, the mean average score on the test is \dfrac{xa+yb+zc}{a+b+c}.

Please answer what the answer for ? Is.

Answer:

5/8

Step-by-step explanation:

A.   2/3 × 4/5 × m = 1/3               B.      4/5 × 2/3 × m = 1/3

      8/15 × m = 1/3                                 8/ 15 × m  = 1/3                                    

                 m = 1/3 ÷ 8/15                                 m = 1/3 ÷ 8/15

                  m = 1/3 ×15/8                                 m = 1/3  × 15/8

                  m = 5/8                                          m = 5/8        

C.  2/3 × 4/5 = 1/3 ÷ m        

            8/15 =  1/3 ×  1/m

            8/15 = 1/3m                   cross multiply  

           (3m) × (8) = 15

                24m = 15

                     m = 15/24

                     m=  5/8
