For this, you have to understand the ratios of a 30,60,90 triangle. The ratio(in order) is x, x(sqrt 3), 2x (following the 30,60,90 pattern y'know). Well, we know the length of the hypotenuse, 4.2, so let's use ratios to figure the other sides out. The ratio of AC is x and the ratio of AB is 2x, so 2x/2=x=2.1. One side down. BC has a ratio of x(sqrt 3). We already know x so we can substitute it in. We get 2.1(sqrt 3). To calculate the area, use the formula 1/2(bh). Inputting the values in, we get 1/2(2.1*(2.1(sqrt 3)). This can be calculated to around 3.82. To calculate the perimeter, take the sum of the sides. By adding the sides together, we get about 9.98. Hope you can now understand how to do these kinds of questions.
Answer:
16-58
Step-by-step explanation:
This is the range of the data set because it's going from 16-58.
Answer:
2 2/3
Step-by-step explanation:
You can set up the equation 
= 2 to solve for this.
You can first multiply both sides by 4 to get 3x = 8
You can then divide both sides by 3 to get x = 
Answer:
The complement of an event A is the collection of all outcomes in the sample space that are not in A.
Step-by-step explanation:
We have to fill the sentence in the given question:
Complement of an event:
- Let A be an event, then complement of an event is defined as the the event with outcome not in A.
- It is represented as A'
- We can write
Thus, we can fill the bank as
The complement of an event A is the collection of all outcomes in the sample space that are not in A.
