Answer:
14) 21.136505024965 m
15) 43.076759215619 km
Step-by-step explanation:
14)
let h be the height of the lighthouse:
tan(41.3) = 18.7/h
Then
h = 18.7÷tan(41.5)
= 21.136505024965 m
………………………………………
15)
90-71.4 =18.6
Let s be the distance that the plane flew
towards the south:
tan(90 - 71.4) = s/128
Then
tan(18.6) = s/128
Then
s = tan(18.6)×128
= 43.076759215619 km
Answer:
2e⁻² ≈ 0.271
Step-by-step explanation:
This is actually a Poisson distribution. The probability is:
P(x; μ) = e^(-μ) (μˣ) / x!
P(2; 2) = e⁻² (2²) / 2!
P(2; 2) = 2e⁻²
P(2; 2) ≈ 0.271
it would be 16 times larger
1. The number 7 is located in the hundred thousands place
2. Since the number 1 is located in the ten thousands place, it's telling 7 to stay the same
Stays the Same: 1,2,3,4
Goes Up: 5,6,7,8, etc...
712,350 ⇒ 700,000
Step-by-step explanation:
slope of the segment through (-9, -8) and (-5, 6) is (-9-(-5))/(-8-6)=-(-4)/(-14)=2/7
this means the slope of the perpendicular is -7/2.
the midpoint of the segment is (-7, -1)
so the line is y+1=(-7/2)(x+7).
