FOr the first one you can do:

y= -x +4

y= -x+2

y = -x

y= -x-2

y = x-4

Answer:

g ≤ 48

Step-by-step explanation:

Let g = # of guest

12.50(g) ≤ 600

$\frac{12.50g}{12.50} \leq \frac{600}{12.50}$

g ≤ 48

Pedro Pascal wants to have $15,000 in an account after five years. He found a bank that will offer him a 7.5% interest rate, com

Juli2301 [7.4K]

Answer-

He needs to put $10345 in the account today, in order to get 15000 in five years.

Solution-

We know that,

$A=P(1+\frac{r}{n})^{nt}$

Where,

A = future value of the investment with interest = 15000

P = principal investment amount

r = annual interest rate (decimal) = 7.5% = 0.075

n = number of times that interest is compounded per year = 4

t = the number of years the money is invested = 5

Putting the values,

$15000=P(1+\frac{0.075}{4})^{4 \times 5}$

$\Rightarrow P=\frac{15000}{(1+0.01875)^{20}} =\frac{15000}{1.01875^{20}} =\frac{15000}{1.45} =10344.8 \approx 10345$

The caller times at a customer service center has an exponential distribution with an average of 22 seconds. Find the probabilit

jenyasd209 [6]

Answer:

The probability that a randomly selected call time will be less than 30 seconds is 0.7443.

Step-by-step explanation:

We are given that the caller times at a customer service center has an exponential distribution with an average of 22 seconds.

Let X = caller times at a customer service center

The probability distribution (pdf) of the exponential distribution is given by;

$f(x) = \lambda e^{-\lambda x} ; x > 0$

Here, $\lambda$ = exponential parameter

Now, the mean of the exponential distribution is given by;

Mean = $\frac{1}{\lambda}$

So, $22=\frac{1}{\lambda}$ ⇒ $\lambda=\frac{1}{22}$

SO, X ~ Exp( $\lambda=\frac{1}{22}$ )

To find the given probability we will use cumulative distribution function (cdf) of the exponential distribution, i.e;

$P(X\leq x) = 1 - e^{-\lambda x}$ ; x > 0

Now, the probability that a randomly selected call time will be less than 30 seconds is given by = P(X < 30 seconds)

P(X < 30) = $1 - e^{-\frac{1}{22} \times 30}$

= 1 - 0.2557

= 0.7443
