Answer:
work is shown and pictured
Step-by-step explanation:
(10x^2 - 8x - 1) + (4x^2 - 8x - 5) = 10x^2 - 8x - 1 + 4x^2 - 8x - 5 = 14x^2 - 16x - 6
Answer:
40k^2(3k - 2) + 48(3k - 2)
(40k^2 + 48)(3k - 2)
8(5k^2 + 6)(3k -2)
Step-by-step explanation:
Answer:
x + y = 4.5
Step-by-step explanation:
x + y = 1.5 + 3 = 4.5
The z-score will be given by:
z=(x-μ)/σ
given that:
x=94
μ=mean=84.5
σ=standard deviation=4.4
thus
z=(94-84.5)/4.4
z=2.1591
