Hokiris ladder has two legs that are each 8 feet long. When the ladder is opened safely and locked for use, the legs are 4 feet
guajiro [1.7K]

To solve this problem you must apply the proccedure shown below:

1- The ladder forms an isosceles triangle, because it has two equal sides.

2- Let's call the angle \alpha. To calculate it , you can divide the triangle into two equal right triangles and the angle \alpha will be divided into two equal parts too. Therefore, you can calculate the half of the angle and then multiply it by two, as following:

Sin^{-1}(\alpha 1)=opposite/hypotenuse

Sin^{-1}(\alpha1)=8/2\\  \alpha1=14.47 degrees

\alpha =2\alpha 1\\ 2=2(14.47degrees)\\ \alpha =28.95degrees

The answer is: 28.95degrees

Entertainment Software Association would like to test if the average age of "gamers" (those that routinely play video games) is
lions [1.4K]

Answer:

"30 years or less when, in reality, the average age is more than 30 years"

Step-by-step explanation:

Type I error is produced when conclusion rejects a true null hypothesis.

The null hypothesis is

"The average gamer is more than 30 years old"

(deduced from the wording, not explicitly stated).

Then if the conclusion is "the average gamer is less than or equal to 30 years old" when in reality the average age is more than 30 years, then there is a type I error, since the null hypothesis is rejected.

Answer is D:

"30 years or less when, in reality, the average age is more than 30 years"
