Answer will be A 200( 12+3)

Answer:

25%

Step-by-step explanation:

25/100 = 25%

The percentage value of $0.25 in one dollar is 25%.

Given data:
The initial amount is represented as $0.25.

The value of one dollar is $1.

To determine what percent $.25 is of one US dollar, divide $.25 by $1 and then multiply by 100 to express it as a percentage.

($.25 / $1) * 100 = 0.25 * 100

0.25 * 100 = 25 %

So, the value is 25 %.

Hence, $.25 is 25% of one US dollar.

Answer:

  7953.873

Step-by-step explanation:

The first derivative is ...

  f'(x) = 4·3x²·e^x +4x³·e^x = e^x(4x³ +12x²)

Then the second derivative is ...

  f''(x) = (12x² +24x)e^x +(4x³ +12x²)e^x

  f''(x) = e^x(4x³ +24x² +24x)

So, f''(3) = (e^3)(4·27 +24·9 +24·3) = 396e^3 = 7953.87262158

Answer:

a) 0.5488 = 54.88% probability that the family did not make a trip to an amusement park last year.

b) 0.3293 = 32.93% probability that the family took exactly one trip to an amusement park last year.

c) 0.1219 = 12.19% probability that the family took two or more trips to amusement parks last year.

d) 0.8913 = 89.13% probability that the family took three or fewer trips to amusement parks over a three-year period.

e) 0.1912 = 19.12% probability that the family took exactly four trips to amusement parks during a six-year period.

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:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

Poisson distributed, with a mean of 0.6 trips per year

This means that [tex]\mu = 0.6n[/tex], in which n is the number of years.

a.The family did not make a trip to an amusement park last year.

This is P(X = 0) when n = 1, so [tex]\mu = 0.6[/tex].

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-0.6}*(0.6)^{0}}{(0)!} = 0.5488[/tex]

0.5488 = 54.88% probability that the family did not make a trip to an amusement park last year.

b.The family took exactly one trip to an amusement park last year.

This is P(X = 1) when n = 1, so [tex]\mu = 0.6[/tex].

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 1) = \frac{e^{-0.6}*(0.6)^{1}}{(1)!} = 0.3293[/tex]

0.3293 = 32.93% probability that the family took exactly one trip to an amusement park last year.

c.The family took two or more trips to amusement parks last year.

Either the family took less than two trips, or it took two or more trips. So

[tex]P(X < 2) + P(X \geq 2) = 1[/tex]

We want

[tex]P(X \geq 2) = 1 - P(X < 2)[/tex]

In which

[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.5488 + 0.3293 = 0.8781[/tex]

[tex]P(X \geq 2) = 1 - P(X < 2) = 1 - 0.8781 = 0.1219[/tex]

0.1219 = 12.19% probability that the family took two or more trips to amusement parks last year.

d.The family took three or fewer trips to amusement parks over a three-year period.

Three years, so [tex]\mu = 0.6(3) = 1.8[/tex].

This is

[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-1.8}*(1.8)^{0}}{(0)!} = 0.1653[/tex]

[tex]P(X = 1) = \frac{e^{-1.8}*(1.8)^{1}}{(1)!} = 0.2975[/tex]

[tex]P(X = 2) = \frac{e^{-1.8}*(1.8)^{2}}{(2)!} = 0.2678[/tex]

[tex]P(X = 3) = \frac{e^{-1.8}*(1.8)^{3}}{(3)!} = 0.1607[/tex]

[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.1653 + 0.2975 + 0.2678 + 0.1607 = 0.8913[/tex]

0.8913 = 89.13% probability that the family took three or fewer trips to amusement parks over a three-year period.

e.The family took exactly four trips to amusement parks during a six-year period.

Six years, so [tex]\mu = 0.6(6) = 3.6[/tex].

This is P(X = 4). So

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 4) = \frac{e^{-3.6}*(3.6)^{4}}{(4)!} = 0.1912[/tex]

0.1912 = 19.12% probability that the family took exactly four trips to amusement parks during a six-year period.

Probabilities are used to determine the chances of events.

The given parameters are:

[tex]p = 0.6[/tex]

The distribution is given as a Poisson distribution.

So, we have:

[tex]P(x) = \frac{e^{-\mu} \times \mu^x}{x!}[/tex]

Where:

[tex]\mu = np[/tex]

Last year means that:

[tex]n = 1[/tex] --- the number of years.

No trip, means that:

[tex]x = 0[/tex]

So, we have:

[tex]\mu = np[/tex]

[tex]\mu = 1 \times 0.6[/tex]

[tex]\mu = 0.6[/tex]

The probability becomes

[tex]P(x) = \frac{e^{-\mu} \times \mu^x}{x!}[/tex]

[tex]P(0) = \frac{e^{-0.6} \times 0.6^0}{0!}[/tex]

[tex]P(0) = \frac{0.5488 \times 1}{1}[/tex]

[tex]P(0) = 0.5488[/tex]

Hence, the probability that the family did not make a trip to an amusement park last year is 0.5488

This means that:

x = 1.

So, we have:

[tex]P(x) = \frac{e^{-\mu} \times \mu^x}{x!}[/tex]

[tex]P(1) = \frac{e^{-0.6} \times 0.6^1}{1!}[/tex]

[tex]P(1) = \frac{0.5488 \times 0.6}{1}[/tex]

[tex]P(1) = 0.3293[/tex]

Hence, the probability that the family took exactly one trip to an amusement park last year is 0.3293

This means that:

x = 2,3...

So, we make use of the following complement rule:

[tex]P(x\ge 2) = 1 - P(x < 2)[/tex]

This gives

[tex]P(x\ge 2) = 1 - P(0) - P(1)[/tex]

So, we have:

[tex]P(x\ge 2) = 1 - 0.5488 - 0.3293[/tex]

[tex]P(x\ge 2) = 0.1219[/tex]

Hence, the probability that the family took two or more trips to an amusement park last year is 0.1219

For a three-year period, we have:

[tex]n = 3[/tex]

So, the mean of the distribution is:

[tex]\mu = np[/tex]

[tex]\mu = 3 \times 0.6[/tex]

[tex]\mu = 1.8[/tex]

The probability is then represented as:

[tex]P(x \le 3) = P(0) + P(1) + P(2) + P(3)[/tex]

Calculate P(0) to P(3) using:

[tex]P(x) = \frac{e^{-\mu} \times \mu^x}{x!}[/tex]

So, we have:

[tex]P(0) = \frac{e^{-1.8} \times 1.8^0}{0!}[/tex]

[tex]P(0) = \frac{0.1653 \times 1}{1}[/tex]

[tex]P(0) = 0.1653[/tex]

[tex]P(1) = \frac{e^{-1.8} \times 1.8^1}{1!}[/tex]

[tex]P(1) = \frac{0.1653 \times 1.8}{1}[/tex]

[tex]P(1) = 0.2975[/tex]

[tex]P(2) = \frac{e^{-1.8} \times 1.8^2}{2!}[/tex]

[tex]P(2) = \frac{0.1653 \times 3.24}{2}[/tex]

[tex]P(2) = 0.2678[/tex]

[tex]P(3) = \frac{e^{-1.8} \times 1.8^3}{3!}[/tex]

[tex]P(3) = \frac{0.1653 \times 5.832}{6}[/tex]

[tex]P(3) = 0.1607[/tex]

So, we have:

[tex]P(x \le 3) = P(0) + P(1) + P(2) + P(3)[/tex]

[tex]P(x \le 3) = 0.1653 + 0.2975 + 0.2678 + 0.1607[/tex]

[tex]P(x \le 3) = 0.8913[/tex]

Hence, the probability that the family took three or fewer trips to amusement parks over a three-year period is 0.8913

A six-year period means that:

[tex]n = 6[/tex]

So, the mean of the distribution is:

[tex]\mu = np[/tex]

[tex]\mu = 6 \times 0.6[/tex]

[tex]\mu = 3.6[/tex]

The probability is then calculated as:

[tex]P(x) = \frac{e^{-\mu} \times \mu^x}{x!}[/tex]

So, we have:

[tex]P(4) = \frac{e^{-3.6} \times 3.6^4}{4!}[/tex]

[tex]P(4) = \frac{0.0273 \times 167.9616}{24}[/tex]

[tex]P(4) = 0.1911[/tex]

Hence, the probability that the family took exactly four trips to amusement parks over a six-year period is 0.1911

Step-by-step explanation:

you should get the x by its self by moving the 1.20 over to the other side then divide by the 4.75 this would get x by its self leaving you to answer and get an answer of 10

Chase rode the taxi for 10 miles.

Let the number of miles in the taxi ride be represented by x.

Pick up fee = $1.20

Amount per mile = $4.75 per mile.

Therefore, the number of miles in the taxi ride will be:

1.20 + (4.75 × x) = 48.70

1.20 + 4.75x = 48.70

Collect like terms

4.75x = 48.70 - 1.20

4.75x = 47.50

Divide both side by 4.75

4.75x/4.75 = 47.50/4.75.

x = 10

Therefore, the number of miles is 10 miles
