Answer: 5.1961
Step-by-step explanation: I believe you would use the Pythagorean’s theorem, since it’s a problem about a ramp, always draw pictures for word problems. So you would plug your numbers in the formula and solve. 3 squared plus B squared (that’s what we are trying to find so its a variable) equals 6 squared. Then you square and it becomes 9 + b2= 36, subtract 9 on both sides, b2=27, then square root on both sides to get 5.1961. Hopefully that’s right. :)
You'd find the vertical asymptotes by seeing where the denominator equals zero; you can do so by factoring the denominator.
In this case, you can factor the denominator into (x+3)(x+2), so if you set each of those equal to zero you can find the equations of the vertical asymptotes (x=-3 and x=-2).
Answer:
C
Step-by-step explanation:
Ax+by= C
Ax -Ax +By = C -Ax
By = C-Ax
By/B = C-Ax/B
y= C-Ax/B
Answer:
99.8 %
Step-by-step explanation:
μ = 75 and σ = 5
The information about 68-95-99.7 rule is:
μ ± 0,5σ 68.3 % of all values will be in the interval
[ μ - 0,5σ ; μ + 0,5σ ] [ 72.5 : 77,5 ]
μ ± 1σ 95 % of all values will be in the interval
[ μ - 1σ ; μ + 1σ ] [ 70 : 80 ]
And:
μ ± 1,5σ 99.7 % of all values will be in the interval
[ μ - 1.5σ ; μ + 1.5σ ] [ 67,5 : 82,5 ]
And still 85 is bigger than 82,5 we can conclude that approximately 99.8 % will be smaller than 85 and then "the relative frecuency of rates less than 85 is very high 99.8 %
