Answer:
- sin(x) = ±(√2)/2
- r.a. = 45°
- x = 45° +k·360°
- x = 135° +k·360°
- x = 225° +k·360°
- x = 315° +k·360°
- x ∈ {135°, 225°, 315°, 405°}
Step-by-step explanation:
Start by solving for sin(x).
4sin(x)² = 2
sin(x)² = 1/2 . . . . divide by 4
sin(x) = ±√(1/2) = ±(√2)/2
Use your knowledge of the sine function to recognize that the reference angle is 45°, and that the angles x will be ...
x = ±45° or 180°±45° with multiples of 360° added
The solutions in the desired range are ...
x ∈ {135°, 225°, 315°, 405°}
I am pretty sure that the right answer on the question represented above is the second option from the scale B. The box plot will be skewed because there are no exceptionally high or low prices. And that's why :
at first you need to arrange the prizes in order <span> 25 , 25 , 25 , 26 , 26 , 27 , 27 , 27 , 28 , 28 , 29
</span>Then find median <span>Q2 = 27
</span>Then you need to get <span>Q1 and Q3, which coincideas with 25, 28
</span>now you have boundaries 25 and 29 and I think its clear now
The formula for the volume, V of a cone is V = (1/3)*π*(radius)^2 * height.
So, as you see you have two variables, radius and height, which means that there are different combinations of radius and height that lead to the same volume.
That implies that your questions is missing some information.
I searched for it and found that the question has a list of answer choices. This is the list:
a) radius 6 inches, height 3 inches
b) diameter 6 inches, height 3 inches
c) diameter 4 inches, height 6 inches
d) diameter 6 inches, height 6 inches
Now you can probe those options to see which leads to an approximate volume of 28 cubic inches.
a) radius 6 in, height 3 in
=> V = (1/3)*3.14*(6in)^2 * 3in = 113.04 in^3 => not possible
b) diameter 6 in, height 3 incdiameter 6 in => radius 3 in=> V = (1/3)*3.14*(3in)^2 * 3in = 28.26 in^3 => this is the answerThe other options lead to values far from 28 in^3.Answer: diameter 6 inches, height 3 inches.
