WHAT IS THE DIFFERENCE BETWEEN SQUARE ROOT AND CUBE ROOT?

2 answers:

6 0

The square root of a number is the number that when you multiply it by its self two times, you get your original number. The cube root is the number when you multiply it by its self three times, you get your original number. For example, the square root of 25 is , because 5*5=25. The cube root of 64 is 4 because 4*4*4=64. Hope this helps!

A square root is the number multiplied by itself twice. 4x4=16
A cube root is the number multiplied by itself 3 times. 4x4x4=16x4= 64

Answer:

Step-by-step explanation:

From the given information:

the mean $(\mu) = 115 \times 20$

= 2300

Standard deviation = $20 \times \sqrt{115}$

Standard deviation (SD) = 214.4761

TO find:

a) $P(x > 3500)= P(Z > \dfrac{3500-\mu}{214.4761})$

$P(x > 3500)= P(Z > \dfrac{3500-2300}{214.4761})$

$P(x > 3500)= P(Z > \dfrac{1200}{214.4761})$

$P(x > 3500)= P(Z >5.595)$

From the Z-table, since 5.595 is > 3.999

$P(x > 3500)=1-0.9999$

P(x > 3500) = 0.0001

Here, the replacement time for the mean $(\mu) = \dfrac{0+0.5}{2}$

= 0.25

Replacement time for the Standard deviation $\sigma = \dfrac{0.5-0}{\sqrt{12}}$

$\sigma = 0.1443$

For 115 component, the mean time = (115 × 20)+(114×0.25)

= 2300 + 28.5

= 2328.5

Standard deviation = $\sqrt{(115\times 20^2) +(114\times (0.1443)^2)}$

= $\sqrt{(115\times 400) +(114\times 0.02082249}$

= $\sqrt{(46000) +2.37376386}$

= $\sqrt{(46000) +(2.37376386)}$

= $\sqrt{46002.374}$

= 214.482

Now; the required probability:

$P(x > 4125) = P(Z > \dfrac{4125- 2328.5}{214.482})$

$P(x > 4125) = P(Z > \dfrac{1796.5}{214.482})$

$P(x > 4125) = P(Z >8.376)$

$P(x > 4125) =1- P(Z$

From the Z-table, since 8.376 is > 3.999

P(x > 4125) = 1 - 0.9999

P(x > 4125) = 0.0001

Which shows the numbers in order from least to greatest?

gavmur [86]

So just convert to a common form
I will convert to decimal since 2 of them are already decimals

to conver 1 and 3/7 to decimal, just divide 3 by 7 using a calculator
1 3/7=1.43...

so 1.38, 1.43, 1.40
the greates is .43 then .40 then .38 so the order is
least to greatest
1.38, 1.4, 1 3/7 or D
