What are the solutions to the equation (x-6)(x+8)=0?

Zepler [3.9K]

Answer:

x = 6, -8

Step-by-step explanation:

If (x - 6)(x + 8) = 0, that would imply that either (x - 6) or (x + 8) would equal zero. Using this, we can find that solving the two equations:

x - 6 = 0

and

x + 8 = 0

would yield the two solutions to the equation.

x - 6 = 0

Add 6 to both sides of the equation.

x = 6

So one of the solutions would be x = 6.

x + 8 = 0

Subtract 8 from both sides of the equation.

x = -8

So the other solution would be x = -8.

The two solutions are x = 6 and x = -8.

I hope you find my answer and explanation to be helpful. Happy studying.

A simple random sample of 64 observations was taken from a large population. The population standard deviation is 120. The sampl

Answer:

<h3>The standard error of the mean is <u>15</u></h3>

Step-by-step explanation:

Given that a simple random sample of 64 observations was taken from a large population.

Hence it can be written as n=64

The population standard deviation is 120.

It can be written as $\sigma_{\overline{X}}=120$

The sample mean was determined to be 320.

It can be written as $\overline{X}=\mu =320$

<h3>To find the standard error of the mean :</h3>

The formula for the standard error of the mean is given by

$\sigma_{\overline{X}}=\frac{\sigma}{\sqrt{n}}$

Now substitute the values in the formula we get

$\sigma_{\overline{X}}=\frac{120}{\sqrt{64}}$

$=\frac{120}{8}$

$=15$

$\sigma_{\overline{X}}=15$

<h3>∴ The standard error of the mean is 15</h3>

area of rectangular field is 726 sq m if the ratio between its length and breadth is 3:2' find the length and breadth.

ale4655 [162]

Answer:

length = 3x = 3 × 11 = 33 m

breadth = 2x = 2 × 11 = 22 m

Step-by-step explanation:

here's the solution :-

let's take the ratio constants be x

so, length = 3x

breadth = 2x

And, we know that area of rectangle =

length × breadth

So,

=》

$3x \times 2x = 726$

=》

$6 {x}^{2} = 726$

=》

${x}^{2} = \frac{726}{6}$

=》

${x}^{2} = 121$

=》

$x = \sqrt{121}$

=》

$x = 11$

so, length = 3x = 3 × 11 = 33 m

breadth = 2x = 2 × 11 = 22 m
