37 students get at most 67 scores.
The numbers 60-67 represent the lower quartile (lowest 25%). 25% of 60 is 15 not 30. Therefore it is incorrect.
Answer:
-13
Step-by-step explanation:
3x^3 - 2y^-6x^2y^2+xy
x=2/3 and y=1/2
Solve :
3x^3 - 2y^-6x^2y^2+xy
Put value of x and y in this equation
= 3(2/3)^3 - 2(1/2)^-6(2/3)^2(1/2)^2+(2/3)(1/2)
= -13
Step-by-step explanation:
A = 2 x 3^4 x 5
B = 2^3 x 3^2 x 5^2
b) Write down the highest common factor (HCF) of A and B.
Answer:
In 5 complete rotations it will go 7.85 m.
Step-by-step explanation:
Diameter = O.5 m
Clare: 5/(2 x 3.14) = 0.795 m
Andre: 5/(4 x 3.14) = 0.397
C = 3.14 x 0.5 = 1.57 x 5 =7.85m
Answer:
The matrix is:
(2............6)
(6...........-5)
Step-by-step explanation:
The coefficient of the squared terms (2 and -5) are written in the diagonal, and the coefficient of x₁x₂ (12) is split equally in each column.
The matrix is:
(2............6)
(6...........-5)
