Divide 20m^2n^3 - 10m^2n by 5mn

1 answer:

6 0

$\frac{20 {m}^{2} {n}^{3} - 10 {m}^{2}n }{5mn} \\ = \frac{5mn(4m {n}^{2} - 2m) }{5mn} \\ = 4 {m}^{2} n - 2m \\ = 2m(2mn - 1)$

Hope this helps. - M

Response Question

Paha777 [63]

Answer:

The right solution is "3.29, 3.57".

Step-by-step explanation:

Seems that the given problem is incomplete. Below is the attachment of the complete and appropriate query.

The given values are:

Randomly selected adults,

$n = 105$

Mean,

$\bar{x} = 3.42$

Standard deviation,

$s = 0.75$

Now,

At 95% confidence level if given by,

= $\bar{x} \ \pm \ Z_{\frac{\alpha}{2} }\times \frac{s}{\sqrt{n} }$

On putting the given values, we get

= $3.42 \ \pm \ Z_{\frac{0.05}{2} }\times \frac{0.75}{\sqrt{105} }$

= $3.42 \ \pm \ 1.96\times 0.073$

= $3.42 \ \pm \ 0.143$

= $3.29, 3.57$

KIM [24]

Answer:

y = 5/4 x - 7

Step-by-step explanation:

y - y1 = m(x - x1)

y + 2 = 5/4 (x - 4)

y + 2 = 5/4 x - 5

y = 5/4 x - 7
