Solve for p. i = prt p = i-rt p = (rt)/i 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:

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

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

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

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 $\dfrac{xa+yb+zc}{a+b+c}$ .

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
