Answer:
13
Step-by-step explanation:
it's a 5,12,13 triangle
and we can find the sides by Pythagorean theorem:
a^2 + b^2 = root of c
25 + 144 = 169
root of 169 = 13
Answer: 17
Step-by-step explanation:
3(5)+2
15+2
F(5)=17
mean = sum/n
mean = (5 + 7 + 7 + 9 + 12 + 16 + 21)/7
mean = 77/7
mean = 11
Using the Emperical rule:
68% lie with one one standard deviation:
16 + 1.7 , 16-1.7 = 17.7, 14.3
14.3 is part of the 68%.
The remaining 32% of the distribution is outside the range, with half being less than and half being greater than.
32/2 = 16
The probability of living loner than 14.3 Would be 16%
The square root of 3.24 is 1.8
