Euler's formula is given by:
C + V = A + 2
Where,
C: number of faces
V: number of vertices
A: number of edges.
Clearing A we have:
A = C + V-2
Substituting values:
A = 21 + 14-2
A = 33
Answer:
the missing number is:
C.33
1. $.0999 = $.1
2. $2.0192 = $2.02
3. $21.5953 = $21.60
4. $35.6667 = $35.67
5. $1.3999 = $1.40
6. $25.3333 = $25.33
Answer:
f(7) = 16
Step-by-step explanation:
substitute x = 7 into f(x) , that is
f(7) = 3(7) - 5 = 21 - 5 = 16
Answer:
Option D, i.e., -0.7.
Step-by-step explanation:
Correlation describes the relation between two variables. It is defined by r and the value of correlation lies in the interval [-1,1].
If r=1, it represents strong positive correlation between two variables.
If r=0, it represents no correlation between two variables.
If r=-1, it represents strong negative correlation between two variables.
It is given that the value of a car decreases with age. The value of one variable decreases if the value of another variable increases. It means, the given problem has negative correlation.
If the data points lie about a straight negative line then coefficient is -1.
Since, the data set is not given, so the it represents moderate negative correlation, i.e, r=-0.7.
Therefore, the correct option is D.
Answer: 5
----------------------------------------------------------
On the curve, the highest point has a y coordinate of y = 6
The lowest point on the curve has a y coordinate of y = -4
Subtracting the y values gets us: 6 - (-4) = 6 + 4 = 10
Cut that result in half: 10/2 = 5
The amplitude is 5. This is the vertical distance from the midline (y = 1) to either the highest point or the lowest point.
