The equation to find a z score is (x- mean)/(standard deviation)
So, in this case the equation would be
(76-70)/(2.1)
For,
X=76
Mean=70
Standard Deviation= 2.1
After solving we find that the z score equals 2.85714
or
2.8571
I think its 2 bc two ppl sit behind each persin from the first and second row.
No. 49 is not a multiple of 14. The only number that can do the job is 3.5 .
Answer:
Option 4 (equilateral)
Step-by-step explanation:
This triangle is an equilateral triangle since all of its sides are equal i.e. 9 cm.
cause sin (×) = 27/32
so to make x alone take the inverse of sin
hence
sin^-1(27/32)=x
i think you can find the sin^-1 on the calculator
