Answer: a

Step-by-step explanation:

$\left(\frac{f}{g} \right)(x)=\frac{f(x)}{g(x)}=\frac{\sqrt{x^{2}-1}}{\sqrt{x-1}}}=\sqrt{\frac{x^{2}-1}{x-1}}=\sqrt{\frac{(x-1)(x+1)}{x-1}}=\boxed{\sqrt{x+1}}$

Indicate whether the following analysis involves a statistical test. If it does involve a statistical test, state the population

eimsori [14]

Answer:

Yes, The analysis involves a statistical test.

The hypothesis are $H_0: \mu_R = \mu_L,\ and\ H_A: \mu_R < u_L$

Step-by-step explanation:

Consider the provided information.

Testing 500 right-handed participants on the reaction time of their left and right hands to determine if there is evidence for the claim that the right hand reacts faster than the left.

Yes, The above analysis involves a statistical test.

Where claim is right hand reacts faster than the left hand.

If right hand reacts faster that means the reaction time of right hand should be smaller than the reaction time of left hand.

Let $\mu_R$ to be the average reaction time of their right hands for the right-handed participants and $\mu_L$ to be the average reaction time of their left hands.

Therefore, the hypothesis are $H_0: \mu_R = \mu_L,\ and\ H_A: \mu_R < u_L$

If Earth was 10 times farther away from the Sun than it is now, which planet would it be closest to? Compare Earth's new distanc

Phoenix [80]

You need the radius of all the orbits
earth radius is 150 million km
1. 150 million x 10 = 1500 million
From the website below Saturn would be the closest at 1,429 million km
1,500,000,000 - 1,429,000,000 = 71,000,000 km = 7.1 * 10^7 km
I hope this helps :D
