12 inches, 180/30 is 6 and 2x6 is 12
Answer:
23
Step-by-step explanation:
3x = 69°
This is because they are vertically opposite angles.
You would have to divide 69 by 3.
69 ÷ 3 = 23
23 · 3 = 69
Given:
To find:
The set of points that includes all of the solutions for the given equation.
Solution:
From the given equation, it is clear that y-values depend on the x-values.
If x is a real number, then y-values are real numbers such that .
So, the set of points that includes all of the solutions for the given equation is defined as for all real numbers.
Therefore, the correct option is B.
Answer:
Correct option: e) a two-way table.
Step-by-step explanation:
In this case the store wants to see whether there is a relationship between the satisfaction level of the customer and their gender.
In statistics when there is a need to analyze or derive a relation between two categorical variables one should use a two-way table.
Categorical variables are qualitative variables that take on specific values that are usually labels. For example, grades obtained in an exam, gender, etc.
In this case the two categorical variables are: Gender and Satisfaction level.
To study the relation between the gender of a customer and their satisfaction level use a two-way table.
Answer:
y+2 = (-1/2)(x-3)
Step-by-step explanation:
Note that as we move from (-17,8) to (3,-2), x increases by 20 and y decreases by 10. Thus, the slope of this line is m = -10/20, or m = -1/2.
The standard equation in point-slope form is y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line. Then, taking data from the point (3, -2), we have
y+2 = (-1/2)(x-3).
Check: Does the point (-17,8) satisfy this equation? Is 8+2 = (-1/2)(-17-3) true?
Is 10 = 10 true? Yes.
