In the diagram, line a is the perpendicular bisector of km. what is the length of km?
sleet_krkn [62]

Answer:

80

Step-by-step explanation:

From the given diagram;

KN = NM

9x - 5 = 7x + 7

9x - 7x = 7 + 5

2x = 12

x = 12/2

x = 6

Since KM= 2KL

KM = 2(6x+4)

KM = 12x + 8

KM = 12(6)+8

KM = 72+8

KM = 80

Hence the length of KM is 80

in general the value of a car decreases with age what would ne the correlation between the age and values of all cars -1, 0.7, 1
ASHA 777 [7]

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.
