Experiments on learning in animals sometimes measure how long it takes mice to find their way through a maze. The mean time is 1

8 seconds for one particular maze. A researcher thinks that a loud noise will cause the mice to complete the maze faster. She measures how long each of 10 mice takes with a noise as stimulus. The appropriate hypotheses for the significance test are (a) $$H_0: \mu = 18; H_a: \mu \neq 18.$$ (b) $$H_0: \mu = 18; H_a: \mu > 18.$$ (c) $$H_0: \mu < 18; H_a: \mu = 18.$$ (d) $$H_0: \mu = 18; H_a: \mu < 18.$$ (e) $$H_0: \overline{x} = 18; H_a: \overline{x} < 18.$$

1. Simplifying Equation Below<br> please help!!
vichka [17]

Answer: 0

Step-by-step explanation:

In this equation 0/y would equal 0, no matter what y is. 0/y means that there's 0 items out of y items (ex: substitute y with 2, it would be 0/2). Beginning with 1*0 (one times zero) the answer there would be 0. Since we already know that 0/y equals 0, the rest of the equation would be 0 - 0 which would equal to 0. Hope this explanation helps :)

Logariths, please help​
Valentin [98]

Answer:

<em>{ - 2 , 8 } </em>

Step-by-step explanation:

log_{4} ( x² - 6x ) = 2

4² = ( x² - 6x )

x² - 6x - 16 = 0

- 6 = - 8 + 2

- 16 = - 8 * 2

( x - 8 )( x + 2 ) = 0 ⇒ x_{1} = - 2 , x_{2} = 8

<em>{ - 2 , 8 }</em>
