Descriptive statistics uses data to provide descriptions of populations. Often this data is represented in the form of tables, charts, graphs, or even just numbers. Here, we organize (visual representation) and analyze data to describe a population.
Inferential statistics utilizes data in such a way that allows us to make predictions, generalizations, and inferences about a population from samples taken. Here, we can compare, predict, and test data in order learn about a population.
Hope this helps.
Answer:
y = 57 - 3x
Step-by-step explanation:
Alice collected 57 skipping stones. And she skipped 3 stones a minute on her pond.
So. if y represents the number of stones left to her and x represents the number of minutes, then by the condition given we can write
y = 57 - 3x ..... (1)
So, this is equation of a straight line in the slope-intercept form. (Answer)
Answer:
Question 1: 0.38, 3/8, 25%
Question 2: 72oz.
Question 3: 165
Step-by-step explanation:
First Question: We can make all the numbers to decimals. 25%= 0.25, 3/8= 0.375, and 0.38 is given. Then we can clearly see that 0.38, 3/8, 25% is the order.
Second Question: There are 16oz. in a pound, so we have to multiply 4.5 and 16. 4.5*16 = 72. There are 72 oz. in 4.5lbs.
Third Question: We just have to plug 5 in, so 7(5)^2 - 10 is our equation. Following the order of equations, we have the exponent first. 5^2 is 25. We end up with 7(25) - 10. Then we have to multiply, so 7*25 = 175. Finally we have 175 - 10 which is 165.

<u>Trigonometric angles :</u>
The trigonometric angles are defined as the angles that are obtained by the ratios of trigonometric functions. It shows the relationship between the sides of the triangle and the angles between them. These values of the trigonometric angles ranges from 0 to 36 degrees.
Below attached shown are the angles on a unit circle which shows the angles for each value of sin, cos and tan, and also the radian measure for each of the angles.
