The county fair charges $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75 at

the fair. Jermaine spent his money only on ride tickets and fair admission. The price of the fair admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Write a linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission.
(b) Explain your answer to Part 1a.

A.)y=1.25x+12.5

B.)ridecost+admission=total

if x=number of tickets and y is total and cost per ride is 1.25,

1.25x+admission=y

when we solve

when x=25, y=43.75

Hope This Helps!!!

Step-by-step explanation:

The county fair charges $1.25 per ticket (which is used for rides). Jermaine bought a total of 25 tickets.

Multiply 1.25 with 25

1.25 x 25 = 31.25

Now subtract the number gotten from the total spent.

43.75 - 31.25 = 12.50

=> The admission fee is $12.50.

----------------------------------------------------------------------------------------------

(a) y = mx + b

b = admission fee = $12.50

m = Cost per ride = $1.25

y = total spent = $43.75

x = number of ride tickets

Plug in the corresponding numbers to the corresponding variable

The linear equation is (for anyone, not just Jermaine) is: y = 1.25x + 12.50

----------------------------------------------------------------------------------------------

(b)

1) As stated above, the cost for admission (which replaces the b, as it is a one-time payment) is $12.50

2) For every ride Jermaine goes on, it will cost him $1.25 (or a ticket).

3) Jeremy has a limited amount of money, or $43.75, so he cannot exceed that number. He also spends that exact amount.

----------------------------------------------------------------------------------------------

(Example: Jeremy)

y = mx + b

b = admission fee = $12.50

m = Cost per ride = $1.25

y = total spent (with $43.75 as the limit)

x = amount of rides that Jermaine can ride in.

43.75 = 1.25(x) + 12.50

Solve for x. Isolate the x. Do the opposite of PEMDAS. First, subtract 12.50 from both sides

43.75 (-12.50) = 1.25x + 12.50 (-12.50)

1.25x = 43.75 - 12.50

1.25x = 31.25

Divide 1.25 from both sides

(1.25x)/1.25 = (31.25)/1.25

x = 31.25/1.25

x = 25

Jermaine can ride in 25 rides.

An article suggests that a poisson process can be used to represent the occurrence of structural loads over time. suppose the me

kirill115 [55]

Answer:

a) $\lambda_1 = 2*2 = 4$

And let X our random variable who represent the "occurrence of structural loads over time" we know that:

$X(2) \sim Poi (4)$

And the expected value is $E(X) = \lambda =4$

So we expect 4 number of loads in the 2 year period.

b) $P(X(2) >6) = 1-P(X(2)\leq 6)= 1-[P(X(2) =0)+P(X(2) =1)+P(X(2) =2)+...+P(X(2) =6)]$

$P(X(2) >6) = 1- [e^{-4}+ \frac{e^{-4}4^1}{1!}+ \frac{e^{-4}4^2}{2!} +\frac{e^{-4}4^3}{3!} +\frac{e^{-4}4^4}{4!}+\frac{e^{-4}4^5}{5!}+\frac{e^{-4}4^6}{6!}]$

And we got: $P(X(2) >6) =1-0.889=0.111$

c) $e^{-2t} \leq 2$

We can apply natural log in both sides and we got:

$-2t \leq ln(0.2)$

If we multiply by -1 both sides of the inequality we have:

$2t \geq -ln(0.2)$

And if we divide both sides by 2 we got:

$t \geq \frac{-ln(0.2)}{2}$

$t \geq 0.8047$

And then we can conclude that the time period with any load would be 0.8047 years.

Step-by-step explanation:

Previous concepts

The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:

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

The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution"

Solution to the problem

Let X our random variable who represent the "occurrence of structural loads over time"

For this case we have the value for the mean given $\mu = 0.5$ and we can solve for the parameter $\lambda$ like this:

$\frac{1}{\lambda} = 0.5$

$\lambda =2$

So then $X(t) \sim Poi (\lambda t)$

X follows a Poisson process

Part a

For this case since we are interested in the number of loads in a 2 year period the new rate would be given by:

$\lambda_1 = 2*2 = 4$

And let X our random variable who represent the "occurrence of structural loads over time" we know that:

$X(2) \sim Poi (4)$

And the expected value is $E(X) = \lambda =4$

So we expect 4 number of loads in the 2 year period.

Part b

For this case we want the following probability:

$P(X(2) >6)$

And we can use the complement rule like this

$P(X(2) >6) = 1-P(X(2)\leq 6)= 1-[P(X(2) =0)+P(X(2) =1)+P(X(2) =2)+...+P(X(2) =6)]$

And we can solve this like this using the masss function:

$P(X(2) >6) = 1- [e^{-4}+ \frac{e^{-4}4^1}{1!}+ \frac{e^{-4}4^2}{2!} +\frac{e^{-4}4^3}{3!} +\frac{e^{-4}4^4}{4!}+\frac{e^{-4}4^5}{5!}+\frac{e^{-4}4^6}{6!}]$

And we got: $P(X(2) >6) =1-0.889=0.111$

Part c

For this case we know that the arrival time follows an exponential distribution and let T the random variable:

$T \sim Exp(\lambda=2)$

The probability of no arrival during a period of duration t is given by:

$f(T) = e^{-\lambda t}$

And we want to find a value of t who satisfy this:

$e^{-2t} \leq 2$

We can apply natural log in both sides and we got:

$-2t \leq ln(0.2)$

If we multiply by -1 both sides of the inequality we have:

$2t \geq -ln(0.2)$

And if we divide both sides by 2 we got:

$t \geq \frac{-ln(0.2)}{2}$

$t \geq 0.8047$

And then we can conclude that the time period with any load would be 0.8047 years.

Use the arc length formula and the given information to find r. Show your work for full credit. s = 8.1 ft θ = (3.14/3)rad r = ?

VladimirAG [237]

This question is simple I'm a little confused on the specifics so I will try my best to help.

s=θ(r)
arc length = angle x radius
2.46888m(or 8.1 ft) = (π/3) x r
$r = (\pi /3)/2.46888$
$r = .425m$
