Step-by-step explanation:
Answer : 12.9 units
explanation :
Sides: a = 7.616 b = 7.211 c = 13.038
Area: T = 23
Perimeter: p = 27.865
Semiperimeter: s = 13.933
Angle ∠ A = α = 29.291° = 29°17'29″ = 0.511 rad
Angle ∠ B = β = 27.597° = 27°35'50″ = 0.482 rad
Angle ∠ C = γ = 123.111° = 123°6'41″ = 2.149 rad
Height: ha = 6.04
Height: hb = 6.379
Height: hc = 3.528
Median: ma = 9.823
Median: mb = 10.05
Median: mc = 3.536
Inradius: r = 1.651
Circumradius: R = 7.783
Vertex coordinates: A[3; -1] B[16; -2] C[9; -5]
Centroid: CG[9.333; -2.667]
Coordinates of the circumscribed circle: U[0; 0]
Coordinates of the inscribed circle: I[3.158; 1.651]
Exterior (or external, outer) angles of the triangle:
∠ A' = α' = 150.709° = 150°42'31″ = 0.511 rad
∠ B' = β' = 152.403° = 152°24'10″ = 0.482 rad
∠ C' = γ' = 56.889° = 56°53'19″ = 2.149 rad
Answer is
= 1.24*5+1.1*2.20+4.5*0.68
= <u>11.68</u>
Answer:
It's more likely that all of the residents surveyed will have adequate earthquake supplies since it has a probability of 98.02% which is very close to 100%.
Step-by-step explanation:
-This is a binomial probability problem with the function:
-Given p=0.3, n=11, the is calculated as:
Hence, the probability that at least 8 have adequate supplies 0.0043
#The probability that non has adequate supplies is calculated as;
#The probability that all have adequate supplies is calculated as:
Hence, it's more likely that all of the residents surveyed will have adequate earthquake supplies since 
and that this probability is 0.9802 or 98.02% a figure close to 1
