Answer:
Step-by-step explanation:
it 4
Yes because it's a random sample and it doesn't target any specific group
Answer:
5.2 feet.
Step-by-step explanation:
The useful equation to use for this problem is sine. Given the angle of measure 64 degrees, we have O (opposite) and H (hypotenuse).
From SOH CAH TOA, we see that we have O and H, so thus we should use sine.
Sine of any angle= opposite/hypotenuse.
Sine of 64= x/5.8
Sine of 64 (times 5.8)=x
x= 5.2 feet.
Additionally, you could use a right triangle calculator to solve for side x.
Answer:
1. In mathematics and statistics, the arithmetic mean, or simply the mean or the average, is the sum of a collection of numbers divided by the count of numbers in the collection. The collection is often a set of results of an experiment or an observational study, or frequently a set of results from a survey.
2. In statistics and probability theory, a median is a value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.
3. The mode is the value that appears most often in a set of data values. If X is a discrete random variable, the model is the value x at which the probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled.
4. the set of values that a given function can take as its argument varies.
Triangle is attached below
The triangle is 12 by 10 by 8
Perimeter:
To find perimeter we add all the sides of the triangle
Perimeter P = 12 + 10 + 8 = 30 units
Semi perimeter:
Semi perimeter is half of its perimeter
We know P = 30
Semi perimeter s= 
= 
= 15 units
Area:
If we know the sides of the triangle then we use Heron's formula to find the area of the triangle
Where s= semi perimeter
a,b,c are the sides of the triangle
s= 15 units
a= 12 units
b= 10 units
c= 8 units
A= 39.7 square units
