Answer: The answer is (B). K'(-6,-4) and L(-3,-3).


Step-by-step explanation:  In the figure, the parallelogram JKLM is drawn on a co-ordinate plane. Here, the co-ordinates of points K and L are (-4,6) and (-3,3) respectively.

Now, when we rotate the parallelogram about the origin through 270° , then we have to make a jump of three consecutive quadrants,.ie., presently we are in the fourth quadrant, so we will the resulting co-ordinates in  the third quadrant and so both x and y co-ordinates of the new points will be negative. Also, the x-co-ordinate and y-co-ordinates of both the points K and L will get reversed. Please see the attached figure.

Thus, the new co-ordinates of K and L are K'(-6,-4) and L(-3,-3).

The answer is B (-6,-4)(-3,-3) You're moving it 3 quadrants. When you turn it the K flips to the bottom left of L

A small manufacturing firm has 250 employees. Fifty have been employed for less than 5 years and 125 have been with the company
sukhopar [10]

Answer:

Step-by-step explanation:

Given that a small manufacturing firm has 250 employees. Fifty have been employed for less than 5 years and 125 have been with the company for over 10 years. So remaining 75 are between 5 and 10 years.

Suppose that one employee is selected at random from a list of the employees

A) Probability that the selected employee has been with the firm less than 5 years = \frac{50}{250 } \\= 0.20

B) Probability that the selected employee has been with the firm between 5 and 10 years

= \frac{75}{250 } \\= 0.30

C) Probability that the selected employee has been with the firm more than 10 years

= \frac{125}{250} =0.50

a) P(A) = 0.2

P(C) = 0.5

P(A or B) = 0.2+0.3 = 0.5

P(A and C) = 0 (since A and C are disjoint)

Find the area and the circumference of a circle with radius 6 m.
Ratling [72]

Answer:

(a) 113.04m²

(b) 37.68m

Step-by-step explanation:

(a)

Area = πr²

=π(6)²

=36π

=113.04m²

(b)

Circumference = 2πr

2π(6) = 12π

=37.68m
