You problem is you don't have any problem. You have a bunch of formulas for the perimeter and area of some shapes.
As for using the formulas, usually you're given all but one of the variables and you can solve for the remaining one.
Notice how the triangle result doesn't have area as a function of a, b and c. That's called Heron's formula and is usually not taught to secondary school students. I don't like to teach it either because Archimedes' Theorem is so much better:
The sides a,b,c and area S of a triangle satisfy
There are 150+ seeds in a watermelon and I don’t know the second question
In the study of probability, you find the chances of an event to happen likely out of the total number of possibilities. Thus, probabilities are always presented as part of a whole: in terms of fractions or percentages.
In this problem, the denominator for the probability would be the total number of possibilities. In combination probability, we use the equation: n!/r!(n-r)!, where 'r' is the number of like things out of 'n' objects. So, the denominator would be 5 drawn chips out of a total of 14 chips. So,
denominator = 14!/5!(14-5)! = 2,002 ways
For the numerator, we multiply the combination for 3 out of 10 chips and 2 out of 4 chips.
Numerator = 10!/3!(10-3)! × 4!/2!(4-2)!
Numerator = 720 ways
Thus, the probability is
Probability = 720/2002 = 360/1001 or 35.96%
Sum of interior angles = 180(n - 2)
in this case n = 5 so 180(5-2) = 180(3) = 540
120 + 120 + x + x + x = 540
3x + 240 = 540
3x = 300
x = 100
answer
B) 100
Answer:
True, It is a example of inferential statistics.
Step-by-step explanation:
There are two types of statistics which are:
- Inferential Statistics
- Descriptive Statistics
In Inferential Statistics we describe the valuable characteristic of the population using a sample of data.
Here, Since the professor is estimating the average score of 1,500 students using an average score of 20 students. So it is Inferential Statistics.
