Answer:
z = 32/3
Step-by-step explanation:
Presuming all the horizontal lines are parallel, the ratios of lengths will be identical.
3/8 = 4/z
3z = 8(4)
z = 32/3
Answer: C
Step-by-step explanation:
I’m pretty sure it’s c because x isn’t less than -2. It goes forever in the directions of positive and negative infinity
Move the 14 over and get
5x = 2
divide by 5
x = 2/5
Answer: Population
In statistics, a population is the entire group of people you want to determine some fact about (eg: average height). A sample is a subset of the population that should ideally represent the population.
Answer: DC=30.5
Step-by-step explanation:
Use trigonometry to solve this question
----------------------------------------------------------
First Step: find BD
- AB relative to 54° is [hypotenues]
- BD relative to 54° is [opposite]
- Therefore, we need to use O/H, which is Sin
- sin(54°)=O/20=20·sin(54°)=16.2
Second Step: Find DC
- DC relative to 28° is [adjacent]
- BD relative to 28° is [opposite]
- Therefore, we need to use O/A, which is tan
- tan(28°)=16.2/A=16.2/tan(28°)=30.5
Hope this helps!! :)
