$110.01

2. Simplifying

Step-by-step explanation:

1. Liam's Problem

First Step: 35.67 x 3 = 107.01

Second Step: 107.01 + 3 = 110.0#

2. Simplifying

First Step: 5 + 2(3 x 4) - 7

Second Step: 5 + 2(12) - 7

Third Step: 5 + 24 - 7

Fourth Step: 29-7=22

(Sorry I put in the numbers in wrong so I edited it to fix it.)

Let f(x) = 2x2 + x − 3 and g(x) = x + 2.<br><br> Find (f • g)(x)

katen-ka-za [31]

Answer:

$(f\cdot g)(x) = 2x^3 + 5x^2-x-6$

Step-by-step explanation:

We are given the two functions:

$f(x)=2x^2+x-3\text{ and } g(x)=x+2$

And we want to find:

$(f \cdot g)(x)$

Recall that this is equivalent to:

$=f(x)\cdot g(x)$

Substitute. Hence:

$(f\cdot g)(x)= (2x^2+x-3)(x+2)$

Expand if desired:

$\displaystyle = x(2x^2+x-3)+2(2x^2+x-3) \\ \\ = (2x^3+x^2-3x)+(4x^2+2x-6) \\ \\\ = 2x^3 + 5x^2-x-6$

Cars arrive at the Wendy's drive-through at a rate of 1 car every 5 minutes between the hours of 11:00 PM and 1:00 AM. on Saturd

mestny [16]

Answer:

1) $P(X = 8) = 0.1033$

$P(X = 9) = 0.0688$

2) Expected number of 200 restaurants in which exactly 8 customers use the drive-through: 20.66

Expected number of 200 restaurants in which exactly 9 customers use the drive-through: 13.76

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

$e = 2.71828$ is the Euler number

$\mu$ is the mean in the given time interval.

Question 1. Use the Poisson distribution to calculate the probability that exactly 8 cars will use the drive-through between 12:00 midnight and 12:30 AM on a Saturday night at Wendy's. Do the same for exactly 9 cars.

Cars arrive at the Wendy's drive-through at a rate of 1 car every 5 minutes between the hours of 11:00 PM and 1:00 AM. on Saturday nights. This means that during 30 minutes, 6 cars expected to arrive. So $\mu = 6$ .
