Answer:
83
Step-by-step explanation:
82+87+83+77+70+80+88= 567
Then you divide that answer by the number of numbers you added by which is 7.
567/7= 81 so 83 was the missing number

Answer:
A) The brand of cars driven by Harvard instructors
C) The types of plants growing in yellowstone
Step-by-step explanation:
Categorical and numerical variables:
- Numerical data can be expressed with the help of numerical.
- Categorical data cannot be expressed by numerical.
- They do no have any particular value.
- They are the non-parametric data.
- Categorical data are also known as qualitative data.
A) The brand of cars driven by Harvard instructors
Since the brands cannot be expressed in numerical, it is a categorical variable.
B) The age of randomly selected biology students.
The age of student are expressed in whole numbers or decimals. Thus, it is a numerical data.
C) The types of plants growing in yellowstone
Again, the type of plants cannot be expressed with the help of numerical. Thus, it is a categorical variable.
Answer:
A. 7π/6.
Step-by-step explanation:
I think you mean a sine of -1/2 and cosine of -√3/2 ( the values in the question are not possible)
Angle π/6 has a sine of 1/2 and a cosine of √3/2 ( from the 30-60-90 triangle).
This angle must be in the third quadrant because the sin and cos are negative.
So the answer is π +π/6 = 7π/6.
