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
Answer:
l = √10 ft
Step-by-step explanation:
Using Pythagorean Theorem, a² + b² = c², where,
a = ½(2) = 1 ft
b = 3 ft
c = l
Plug in the values
1² + 3² = l²
1 + 9 = l²
10 = l²
√10 = l
l = √10 ft
