Answer:

<h3>Option c) H_a:\mu is correct</h3><h3>The alternate hypothesis for the significance test is H_a:\mu</h3>

Step-by-step explanation:

The alternate hypothesis use the sumbol for the population value

Let p be the proportion , Mean be \mu and stadard deviation be \sigma

The null hypothesis states that population value is equal to the value mentioned in the given claim.

H_0:\mu=18 (by given).

The alternate hypothesis for the significance test states that the opposite of the null hypothesis(based on the claim )

∴ H_a:\mu

The symbol "<" because we want to test if the maze is completed faster and thus if the time has decreased.

<h3>∴ option c) H_a:\mu is correct.</h3>

Answer:

20.4 ft

Step-by-step explanation:

Since they're similar triangles (same shape, but not necessarily the same size), then you can set them up as fractions to find the missing measure.

6/9.7 = ?/33

A quick way to do use this setup is to multiply 33 by 6, then divide by 9.7.

This gives you 20.4 ft

zavuch27 [327]
Automatically your going to spend $43.00 just on tickets with the $3.00 service fee. So 6x5=30. The 6 equals 6 bags of popcorn and 5 equals the cost of the bags of popcorn. if you add 30 and $43.00 you get $73.00 With 2 dollars left to spends. So the max number of bags of popcorn he can buy is 6 bags!
