A car rental costs $32 as a base fee, plus $28 per day. Use the explicit rule f (n )= 28n + 32

alexdok [17]

Answer:

The charges paid for the first four days are:

$144.

Step-by-step explanation:

To obtain the charges paid for the first 4 days, you must use the given explicit rule given:

f (n) = 28n + 32

Where:

n = Number of days the person rents the car.

As we need to obtain the charges to 4 days, we replace this value in the explicit rule:

f (n) = 28n + 32
f (4) = 28(4) + 32
f (4) = 112 + 32
f (4) = 144

With these calculations, you can identify the charges paid for the first 4 days are $144, where $112 is the money by each day of the four days and $32 is the base fee.

A local animal rescue organization receives an average of 0.55 rescue calls per hour. Use the Poisson distribution to find the p

andreyandreev [35.5K]

Answer:

B) 0.894

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 interval.

A local animal rescue organization receives an average of 0.55 rescue calls per hour.

This means that $\mu = 0.55$

Probability that during a randomly selected hour, the organization will receive fewer than two calls.

$P(X < 2) = P(X = 0) + P(X = 1)$

In which

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

$P(X = 0) = \frac{e^{-0.55}*(0.55)^{0}}{(0)!} = 0.577$

$P(X = 1) = \frac{e^{-0.55}*(0.55)^{1}}{(1)!} = 0.317$

$P(X < 2) = P(X = 0) + P(X = 1) = 0.577 + 0.317 = 0.894$

Help please explain

MatroZZZ [7]

Given:

$\sin^{-1}\left(\dfrac{5}{8}\right)=A$

To find:

The correct equivalent equation.

Solution:

We have,

$\sin^{-1}\left(\dfrac{5}{8}\right)=A$

Taking sin on both sides, we get

$\sin \sin^{-1}\left(\dfrac{5}{8}\right)=\sin A$

$\dfrac{5}{8}=\sin A$ $[\because \sin (\sin^{-1}\theta )=\theta]$

Interchanging the sides, we get

$\sin A=\dfrac{5}{8}$

Therefore, the correct option is 4.

How do I do number 4

nikitadnepr [17]

Answer:

its 6.40

Step-by-step explanation:

you have to use the distance formula which is

$d=\sqrt(x2-x1)^{2} + (y2-y1)^2$

so points C is (-5,-1) and D is (0,3)

then you substitute the x

0--5=5^2

then

3--1+4^2=16

25+16=41

then square rout that and it equals 6.40
