what percent of one us dollar is $.25
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 %.

Roberto rented a truck from the Super Truck Company for 9 hours. There was a rental fee of $50. Allison rented a truck from Trucking America for 4 hours. She paid a $110 rental fee. Both Roberto and Allison spent the same amount and both companies have the same hourly rental fee. Write and solve an equation to determine the hourly rental fee.
Answer:
Hence, the hourly rental fee is [tex]\$\: 12[/tex].
Step-by-step explanation:
Time for which Roberto rented the truck [tex]=9[/tex] hours.
Rental fee [tex]=\$ \:50[/tex]
Time for which Allison rented the truck [tex]=4[/tex] hours.
Rental fee [tex]=\$ \:110[/tex]
Both companies have the same hourly rental fee.
Let the hourly rental fee of both the companies be [tex]x[/tex].
Both spent the same amount.
So, according to the question,
[tex]\Rightarrow 50+9x=110+4x[/tex]
[tex]\Rightarrow 9x-4x=110-50[/tex]
[tex]\Rightarrow 5x=60[/tex]
[tex]\Rightarrow x=\frac{60}{5}[/tex]
[tex]\Rightarrow x=12[/tex]
Hence, the hourly rental fee is [tex]\$\: 12[/tex].
Chase took a taxi from his house to the airport. The taxi company charged a pick-up fee of $1.20 plus $4.75 per mile. The total fare was $48.70, not including the tip. Write and solve an equation which can be used to determine xx, the number of miles in the taxi ride. i need the equation and the answer of what is x
Answer:
(48.70-1.20)/4.75 = x x=10
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

The average number of annual trips per family to amusement parks in the UnitedStates is Poisson distributed, with a mean of 0.6 trips per year. What is the probabilityof randomly selecting an American family and finding the following?a.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.c.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.e.The family took exactly four trips to amusement parks during a six-year period.
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]
(a) The family did not make a trip to an amusement park last yearThe 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
(b) The family took exactly one trip to an amusement park last yearThis 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
(c) The family took two or more trips to amusement parks last yearThis 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
(d) The family took three or fewer trips to amusement parks over a three-year period.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
e. The family took exactly four trips to amusement parks during a six-year period.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

Which expressions are equivalent to √-27?
Answer:
the first one and that's the only one
[tex]3i\sqrt{3} \ \text{ and } \ i\sqrt{27}[/tex]
===================================================
Work Shown:
We will use the rule that sqrt(A*B) = sqrt(A)*sqrt(B) to get the following
[tex]x = \sqrt{-27}\\\\x = \sqrt{-1*27}\\\\x = \sqrt{-1}*\sqrt{27}\\\\x = i\sqrt{27} \ \text{ ... one answer; choice D}\\\\x = i\sqrt{9*3}\\\\x = i\sqrt{9}*\sqrt{3}\\\\x = i*3*\sqrt{3}\\\\x = 3i\sqrt{3} \ \text{ ... another answer; choice A}\\\\[/tex]
While choices C and D seem to look equivalent, note how the 'i' is under the square root in choice C. The 'i' term must be outside the root to be equivalent to the original expression. We denote [tex]i=\sqrt{-1}[/tex]

Factor the trinomial below.
8x2 - 12x - 8
O A. 4(2x + 1)(x - 2)
B. 4(2x + 2)(x - 1)
O C. 4(2x + 3)(x - 1)
D. 4(2x + 1)(x-8)
Answer:
A. [tex]4(2x+1)(x-2)[/tex]
Explanation:
[tex]8x^{2} -12x-8[/tex]
1. You can factor out a 4.
[tex]4(2x^{2} -3x-2)[/tex]
2. Factor [tex](2x^{2} -3x-2)[/tex].
X-Method:
1. Draw an X
2. Multiply ac (2(-2)=-4) then put it in the top part of the X
3. Then put b, -3, in the bottom part of the X
4. On the two sides of the X find out what added together equals b, -3,
and multiplied equals ac, -4.
5. -4(1)=-4 & -4+1=-3
6. If the quadratic has a coefficient then you must divide the two sides
of the X by that coefficient, 2.
7. -4/2=-2 & 1/2 can't be evenly divided into, so in this case the
coefficient remains.
8. When you write this out it will be (2x+1)(x-2)
3. Put it together to get your answer.

A
Step-by-step explanation:
chance rolls a 1-6 number cube. What is the probabilty that he will roll a prime number
Answer:
B
Step-by-step explanation:
There are six numbers altogether. 2 3 and 5 are prime. One is odd, but it is not considered prime.
So P(prime) = 3/6 = 1/2
As a percent, this is 1/2 * 100 = 50%
Which equation matches the hanger?
O X+3=6
0 3x = 6
0 6 = 3x +1
2x = 6
Answer:
B. 3x = 6
Step-by-step explanation:
The left side of a hanger is on the left side of the equation, and the right side of a hanger is on the right side of the equation.
There are 3 x's on the left side, so the left side is 3x
The right side shows 6 unit boxes, so the right side is (1 * 6), or 6.
As a result, the equation is 3x = 6, which is B.
