An exterior angle of a triangle is equal to the sum of the opposite interior
angles
4x - 20 = 2x - 4 + 52
4x - 2x = 20 - 4 + 52
2x = 68
x = 68/2
x = 34
Answer: D. 0.1217
Step-by-step explanation:
Given : The probability that a car will have a flat tire while driving through a certain tunnel :p=0.00005.
n= 14000
Then, the mean number of cars will have a flat tire while driving through a certain tunnel = np
Poisson Distribution Formula : 
For x= 2
Hence, the required probability = 0.1217
Linear, when you plot the numbers it will be in a line. Remember “(line)ar”
Answer:
The numbers are 50 & -72.
Step-by-step explanation:
Let the first number is x and the second number is y.
According to the question:-
x + y = -22 ........(1)
x - y = 122 ........(2)
By adding equation 1 & 2-
2 x = 100
x = 50
Put X =50 in equation (1)-
y = -22 -50
y = -72
Hence the numbers are (50, -72).
Answer:
Correct option is A
Step-by-step explanation:
Given some statements we have to choose the correct statement.
A. Square BCDF is a rectangle.
As we know, all the properties of rectangle satisfied by square. Therefore, we say that all squares are rectangles. hence, Square BCDF is a rectangle is true statement.
B. Rectangle GJKM is a square.
As explained in above, all the properties of rectangle satisfied by square but its converse is not true i.e all rectangles are not square. Hence, Rectangle GJKM is a square is not always true.
C. Quadrilateral STPR is a trapezoid.
All the properties of trapezoid are not satisfied by all quadrilateral hence, not always true.
D. Parallelogram ABCD is a rhombus
All the properties of rhombus are not satisfied by parallelogram like all sides of rhombus are congruent but parallelogram has only opposite sides congruent. hence, not always true.
Correct option is A.
