This would be 16
I hope this helped!!!
Answer:
μ−2σ = 1,089.26
μ+2σ = 1,097.62
Step-by-step explanation:
The standard deviation of a sample of size 'n' and proportion 'p' is:
If n=1139 and p =0.96, the standard deviation is:
The minimum and maximum usual values are:
Answer:
<h2><u><em>w = -4</em></u></h2>
Explanation:
5w + 4 = -16
- <u>Subtract 4 From Both Sides</u>
5w + 4 - 4 = -16 - 4
5w = -20
- <u>Divide Both Sides By 5</u>
5w / 5 = -20 / 5
<h2><em><u>w = -4</u></em></h2>
The formula you need to know is that the side opposite of the 30° angle is always half the hypotheneus. For example in question 2 X should be 6 since 3 is opposite side of the angle 30°. In a 45 45 90 triangle, it is important to know that the straight sides are always the same length (since they are the same angle). For example in question 9, v is also 9√2.
When you have two sides, you can figure out the third side with a² + b² = c² since they are all right triangles. Good luck
