Here is the solution...

1) \sqrt[3]{135} \\

Solution

We can rewrite \sqrt[3]{135} = \sqrt[3]{27} *\sqrt[3]{5}

Here, \sqrt[3]{27} = 3

Now substitute the value, we get

\sqrt[3]{135} = 3 \sqrt[3]{5}

The answer is 3\sqrt[3]{5}


2) -5\sqrt[3]{40} Solution[tex]-5\sqrt[3]{40} = -5\sqrt[3]{8} *\sqrt[3]{5}

Here \sqrt[3]{8} = \sqrt[3]{2^{3} } = 2\\

Therefore, we get -5*2\sqrt[3]{5} = -10 \sqrt[3]{5}

The answer is-10 \sqrt[3]{5}[/tex]


2) 2\sqrt[3]{5} * 4\sqrt[3]{8}

Solution

\sqrt[3]{8} = 2

Now plug in the above in the given expression, we get

2\sqrt[3]{5} * 4*2 = 16\sqrt[3]{5}                         {2*4*2 = 16]

The answer is 16\sqrt[3]{5}

What is the Co ordinates to fill in the grid in the top left?
wolverine [178]

Answer:

a ) x = - 3, y = 5

x = 0, y = 2

x = 5, y = - 3

b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.

Step-by-step explanation:

y = 2 - x

When x = - 3,

y = 2 - x

= 2 - ( - 3 )

= 2 + 5

y = 7

When x = 0,

y = 2 - x

= 2 - 0

y = 2

When x = 5,

y = 2 - x

= 2 - 5

y = - 3

b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.

Why is the central limit theorem important in statistics? a) Because for a large sample size n, it says the population is approx
Katarina [22]

Answer:

The correct option is (c).

Step-by-step explanation:

According to the Central Limit Theorem if we have a population with a known mean and standard deviation and appropriately huge random samples (n > 30) are selected from the population with replacement, then the distribution of the sample means will be approximately normally distributed.

Then, the mean of the distribution of sample means is given by, the population mean.

And the standard deviation of the distribution of sample means is given by,

SD_{\bar x}=\frac{SD}{\sqrt{n}}

So, the most basic and main objective of the Central limit theorem is to approximate the sampling distribution of a statistic by the Normal distribution even when we do not known the distribution of the population.

Thus, the correct option is (c).

What is the standard form of y=3/8x-4
Gennadij [26K]
(-3/8)x+y=(-4), standard form formula is ax +by = c. So you just move them to the correct sides by adding or subtracting.

Please help me for 3 and 4
Andru [333]
Linear functions always go up by the same value. You can subtract 2 y values and divide it by the corresponding x values (subtracted the same way) and you will get the same number. Here is an example from ur chart. 3). (9-7)/(3-2) = 2. Now try it for another two values. You get 2. That means it is linear. The equation for it would be y=2x+3
Now do the next one good luck!

Who can solve this question?I will mark them as branlist.​
mina [271]

Answer:

See below

Step-by-step explanation:

\overrightarrow a= \bigg(\frac{5}{\sqrt 34},\:\frac{3}{\sqrt 34}\bigg)

We have to show that \overrightarrow a is an unit vector.

To show this, we will find the modulus of \overrightarrow a and if its value is 1, it will be a unit vector.

So,

| \overrightarrow a|  =  \sqrt{\bigg(\frac{5}{\sqrt 34} \bigg)  ^{2}+\bigg(\frac{3}{\sqrt 34}\bigg)^{2} }  \\  \\  | \overrightarrow a|  =  \sqrt{\frac{25}{ 34} +\frac{9}{ 34} }  \\  \\  | \overrightarrow a|  =  \sqrt{\frac{25 + 9}{ 34} }   \\  \\  | \overrightarrow a|  =  \sqrt{\frac{34}{ 34} }  \\  \\  | \overrightarrow a|  =  \sqrt{1}  \\  \\ | \overrightarrow a|  =  1

Thus, \overrightarrow a is a unit vector.
