Answer:
Step-by-step explanation:
To add efficiently, you would need to have a common denominator. in this case the least common denominator (LCD) would be 35. 1/7 = 5/35 and 2/5 = 14/35
add the numerators together to get your answer:
19/35
Answer:
a=24
Step-by-step explanation:
= -4
-a= -4*6
-a= -24
a= 24
Answer:
P(2)=0.256
Step-by-step explanation:
We know that Nancy has noticed that 20 trucks pass by her apartment daily (24 hours). We conclude that for 1 hours, pass 20/24=5/6 trucks.
We calculate how many trucks pass for 3 hours:
3 · 5/6= 15/6=2.5=λ
We use a Poisson distribution:
P(k)=\frac{λ^k · e^{-λ}}{k!}
For 2 trucks we have that is k=2. We know that is λ=2.5
We caclulate the probability
P(2)=\frac{2.5² · e^{-2.5}}{2!}
P(2)=0.256
Answer:
The answer 28.27 *2 = 56.54
Step-by-step explanation:
A= πr^2
To determine x intercept get y=0 then substitute in equations: y=6x-11
0=6x-11 then x= 11/6
To determine y intercept get x=0 then substitute in equations: y=6x-11
y=6(0)-11 then y=-11
