θ = 60°
To find:
sin 60°
Solution:
The reference image is attached below.
The given triangle is a right triangle.
θ = 60°
Using basic trigonometric ratio formula:
The value of sin 60° = .
In the given figure, the values of adjacent side, opposite side and hypotenuse are not given.
Answer:

General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x² + 4x
f(-7) is x = -7
<u>Step 2: Solve</u>
- Substitute: f(-7) = (-7)² + 4(-7)
- Evaluate: f(-7) = 49 + 4(-7)
- Multiply: f(-7) = 49 - 28
- Subtract: f(-7) = 21
Answer:
$3190.00
Step-by-step explanation:
Answer with Step-by-step explanation:
Since we have given that
Mean price of an existing single family home = $243761
So, the hypothesis:
Type I error is a error in which null hypothesis is correct and actual but it gets rejected.
It means mean price is exactly $243761, but it is proved that mean price would be higher than $246761.
Type II error is a error in which null hypothesis is not correct but inspite of that it gets accepted.
So, here, mean price is higher than $243761 but it is proved by calculation that mean price is equal to $243761.
