Answer:

The simplified equation is \pm\frac{\sqrt{b^2-4ac}}{2a}

Step-by-step explanation:

Step 1:Applying Quotient Rule

\sqrt[n]{\frac{a}{b}}=\frac{\sqrt[n]{a}}{\sqrt[n]{b}},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0

\pm \sqrt{\frac{b^2-4ac}{4a^2}} = \pm \frac{\sqrt{b^2-4ac}}{\sqrt{4a^2}}----------------------------(1)

Step 2:  Applying radical Rule

\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0

\sqrt{4a^2}=\sqrt{4}\sqrt{a^2}

So equation(1) can be written as

\pm \sqrt{\frac{b^2-4ac}{4a^2}} = \pm \frac{\sqrt{b^2-4ac}}{\sqrt{4}\sqrt{a^2}}-----------------------------(2)

Now

\sqrt{4} = 2

\sqrt{a^2} = a

Now equation(2) becomes

\pm \sqrt{\frac{b^2-4ac}{4a^2}} =  \pm \frac{\sqrt{b^2-4ac}}{2a}

The described situation requires inference about a mean or means. Identify the response variable and whether the setting involve
Liono4ka [1.6K]

Answer:

Step-by-step explanation:

Hello!

The experiment was designed to proof if the physiological blind spot can be reduced with eye training.

One sample of n people was taken and the physiological blind spot was measured. After that, the people selected underwent 3 weeks of eye training and their physiological blind spot was measured again. At the end of the experiment you have two sets of data for the sample, let's call X₁: physiological blind spot of one person before taking eye training", the measurements were taken before the training will correspond to this variable, and X₂: physiological blind spot of one person after three weeks of eye training" the second measurements correspond to this variable.

In this type of situation, where only one sample is taken and both variables are measured to the same observational unit (there is a pair of observations for each person), the observations are dependant and the corresponding test is the paired samples t-test.

To analyze the information you need to create a new variable, usually symbolized as Xd, that will be the difference between X₁ and X₂.

So your response variable would be

Xd: "Difference between a physiological blind spot of one person before taking eye training and physiological blind spot of after three weeks of eye training"

Xd= X₁ - X₂

The study parameter will be the mean of the variable "difference" μd.

I hope it helps!

10. 14. A new DVD player has a purchase price of $430. With the extended warranty, the total cost is
sergejj [24]
Subtract 430 and 512 and turn into a percent
82%
Than 430+512is942
Divide by 82%is11.487804
Skip a few times until u reach 11.48
Add 4+8 and then dvd:1 dvd to buy
So 4+8is12 plus 11 is 23 and one dvd it’s 24
So the answe is 24%

51^7 -51^6 by 25<br> __*25
BartSMP [9]

Answer:

Step-by-step:

51⁷-51⁶ = 51⁶(51-1) = 51⁶(50)

50 is divisible by 25, so 51⁷-51⁶ is divisible by 25.
