Hello there!

To solve 5a + 19 < -27,
you would have to subtract 19 on both sides to isolate 5a.

5a + 19 < -27
      - 19    -19
-------------------
         5a < -46

We need a, not 5a. So divide both sides by 5.

        5a < -46
         a < -46/5
-46/5 can be simplified as -9.2

So your answer is a < -9.2

A woman saw oranges and mangos ad the market. She bought some oranges at 35 cents each and some mangoes at $1.00. if she bought
marysya [2.9K]

Answer: 20 oranges and 5 mangoes

Step-by-step explanation:

Define the following:

x = number of oranges

y = number of mangoes

Make the following system of equations:

x + y = 25

0.35x + 1.00y = 12.00

Solve for x:

y = 25 - x

⇒ 0.35x + 1.00(25 - x) = 12.00

⇒ 0.35x + 25 - x = 12.00

⇒ -0.65x = -13.00

⇒ x = 20

Solve for y:

20 + y = 25

y = 5

∴ 20 oranges and 5 mangoes were purchased.

During off hours, cars arrive at a tollbooth on the East-West toll road at an average rate of 0.5 cars per minute. The arrivals
Norma-Jean [14]

Answer:

P(X=3) = 2.5^3 \frac{e^{-2.5}}{3!}=0.214

Step-by-step explanation:

Definitions and concepts

The Poisson process is useful when we want to analyze the probability of ocurrence of an event in a time specified. The probability distribution for a random variable X following the Poisson distribution is given by:

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

And the parameter \lambda represent the average ocurrence rate per unit of time

For this case we know that \lambda =0.5 cars/min

And we want the probability that during the next five minutes, three cars will arrive, so then our rate becomes:

\lambda = 0.5 \frac{cars}{min}* 5 min = 2.5 cars

And we want this probability:

P(X=3)

And if we use the pmf we got:

P(X=3) = 2.5^3 \frac{e^{-2.5}}{3!}=0.214
