Answer:
8
Step-by-step explanation:
12x+24+8x-4=180degree
=20x+20=180
=20x=180-20
=20x=160
=x =8
Step-by-step explanation:
f(1)=(3×1)+1=4
so f(g(1)=4
Answer:
The probability is 0.0069
Step-by-step explanation:
First thing to do here is to calculate the z-score
Mathematically;
z-score = (x-mean)/SD/√(n)
where x = 9.1 , mean = 8.4 , SD = 1.8 and n = 40
Plugging these values into the z-score equation, we have;
z-score = (9.1-8.4)/1.8/√(40) = 0.7/1.8/6.325 = 0.0615
Now, we check the standard normal table for P(z > 2.46) = 0.0069
2 is a factor of 4x + 2y
2( 2x + y)
