Answer: B) 12.5

Step-by-step explanation:

Start by isolating x by subtracting 2.5 from both sides

x+2.5 < 20\\x+2.5-2.5 < 20-2.5\\x < 17.5

This reads as "x is less than 17.5"

D can be eliminated because it is greater than 17.5

C can be eliminated because 17.5 can't be less than itself

So the answer must be B since it is less than 17.5 and greater than A

Answer: x<17.5

Step-by-step explanation:

Subtract  from both sides: x+2.5-2.5<20-2.5

Simplify the arithmetic: x<20-2.5

Simplify the arithmetic: x<17.5

Hope it helps!

. In the Journal of Transportation Engineering (June 2005), the number of non-home-based trips per day taken by drivers in Korea
Temka [501]

Answer:

So, the probability  that a randomly selected Korean driver will take two or more non-home-based trips per day is P=0.32.

Step-by-step explanation:

We know that the number of non-home-based trips per day taken by drivers in Korea was modeled using the Poisson distribution with λ = 1.15.

We have the Poisson formula:

P(X=k)=\frac{\lambda^k\cdot e^{-\lambda}}{k!}

We calculate:

P(X\geq 2)=1-P(X=0)-P(X=1)\\\\P(X\geq 2)=1-\frac{1.15^0\cdot e^{-1.15}}{0!}-\frac{1.15^1\cdot e^{-1.15}}{1!}\\\\P(X\geq 2)=1-0.32-0.36\\\\P(X\geq 2)=0.32

So, the probability  that a randomly selected Korean driver will take two or more non-home-based trips per day is P=0.32.

Got a question on my math quiz asking the questions below. The question marked me as wrong, but didn’t tell me what I got wrong/
Vikki [24]

Answer:

1.33333... is a rational number because you know that the repeating part will all be 3 because it follows a pattern.

This is different from the first number because that repeating number does not have any identifiable pattern.
