Norman spends $100. He spends $35 on a video game. What percentage of his original $100 does Norman have left after buying the game?
Answers
To find the percentage of Norman's original $100 that he has left after buying the game, subtract the cost of the game from $100 and then calculate the percentage. Norman has 65% of his original $100 left after buying the game.
Explanation:To find the percentage of Norman's original $100 that he has left after buying the game, we need to subtract the cost of the game from $100 and then calculate the percentage.
Subtract $35 from $100: $100 - $35 = $65.Calculate the percentage of $65 out of the original $100: $65 / $100 × 100 = 65%.Therefore, Norman has 65% of his original $100 left after buying the game.

The fuel efficiency in miles per gallon of all bmw 320i's is (approximately) normally distributed with a mean of 25 and a standard deviation of 2. a dealer receives a shipment of a random sample of 320i's (random with respect to m.p.g., that is) from the factory. find the probability that average fuel efficiency for this shipment is less than 24 miles per gallon if the dealer receives (i) one car, (ii) four cars and (iii) sixteen cars. explain briefly why these three answers differ.
Answers
μ = 25 mpg, the population mean
σ = 2 mpg, the population standard deviation
If we select n samples for evaluation, we should calculate z-scores that are based on the standard error of the mean.
That is,
[tex]z= \frac{x-\mu}{\sigma / \sqrt{n} } [/tex]
The random variable is x = 24 mpg.
Part (i): n = 1
σ/√n = 2
z = (24 -25)/2 = -0.5
From standard tables,
P(x < 24) = 0.3085
Part (ii): n = 4
σ/√n = 1
z = (24 -25)/1 = -1
P(x < 24) = 0.1587
Part (iii): n=16
σ/√n = 0.5
z = (24 - 25)/0.5 = -2
P(x < 24) = 0.0228
Explanation:
The larger the sample size, the smaller the standard deviation.
Therefore when n increases, we are getting a result which is closer to that of the true mean.

Suppose the number 1155 is written as the product of three positive integers. What is the smallest possible value of the sum of those three integers?
Answers
1155 equals 11 times 105. Next, determine factors of 105. I see that 5 is a divisor of both 10 and 5, so that 105 equals 5 times 21.
Adding together these three integers: 11+5+21 = 37
But wait! 21 can be factored (e. g., into 7 times 3).
You'll need to identify all of the several sets of 3 positive integers each and find the sum of each set. Only after you've done this can you choose the set whose sum of the three integers is the smallest. Please show your work, so that others can give you feedback on it.
Find the probability that a randomly selected student is male, given that the student is a nursing major. the probability is . 027.027. (round to three decimal places as needed.) (b) find the probability that a randomly selected student is a nursing major, given that the student is male. the probability is nothing. (round to three decimal places as needed.)
Answers
Final answer:
The probability that a randomly selected student is male, given that the student is a nursing major, is 0.027. The probability that a randomly selected student is a nursing major, given that the student is male, is undefined.
Explanation:
To find the probability that a randomly selected student is male, given that the student is a nursing major, we can use conditional probability. Let's assume that P(M) represents the probability of selecting a male student, and P(N) represents the probability of selecting a nursing major. The given information states that P(M|N) = 0.027, which means the probability of selecting a male student, given that the student is a nursing major, is 0.027.
To find the probability that a randomly selected student is a nursing major, given that the student is male, we can use conditional probability once again. The given information states that P(N|M) = nothing. This implies that there is no information given about the probability of selecting a nursing major, given that the student is male. Therefore, the probability is undefined and we cannot determine an answer.

Alicia draws a diagram to represent two forces, F1 and F2, acting on a body. The angle between the directions of the forces is 50° as shown in the diagram. Alicia notices that she can use the Law of Cosines to find the magnitude of the resultant force R in the diagram. What is the value of R?
Answers
When the two forces F₁ and F₂ are added vectorially, the resultant force is R.
The angle x = 180° - 50° = 130°.
From the Law of Cosines, obtain
R² = F₁² + F₂² - 2F₁F₂ cos(130°)
Note that 2 cos(130°) = -1.2856.
Answer:
R = √(F₁²+ F₂² + 1.2856 F₁F₂ )

Write the equation for a parabola with a focus at (0,-5)(0,−5)left parenthesis, 0, comma, minus, 5, right parenthesis and a directrix at y=-3
Answers
The equation of a parabola with a focus at (0,-5) and a directrix at y=-3 is derived by equating the distances of any point (x, y) in the parabola from the focus and the directrix respectively. Simplifying these expressions leads to the equation y = (1/8)x² - 1.
Explanation:The equation for a parabola can be derived from its definition. A parabola is defined as the set of all points (x, y) in a plane which are equidistant from a fixed point, the focus (given here as (0,-5)) and a fixed line, the directrix (given as y=-3).
Let's calculate the distance between the focus (0, -5) and any point in the parabola (x, y). We get the equation:
√[(x-0)² + (y-(-5))²].
And the distance between the point (x, y) and the directrix (y=-3) is |y - (-3)| = y + 3.
Since we know that the two distances are equal, we can equate the two expressions:
√[(x-0)² + (y-(-5))²] = y + 3.
Solving it further, squaring both sides, and simplifying, we get:
y = (1/8)x² - 1.

A random triangle is formed in some way, such that all pairs of angles have the same joint distribution. what is the correlation between two of the angles (assuming that the variance of the angles is nonzero)?
Answers
The correlation between two angles in a random triangle is negative. This means that as one angle increases, the other angle decreases, and vice versa.
How to find what is the correlation between two of the anglesIn a random triangle, the angles are not independent of each other; they are constrained by the fact that the sum of the angles in any triangle must be 180 degrees (or π radians). Let's consider two of the angles, say A and B, in the triangle.
Since the sum of all three angles is a constant (180 degrees or π radians), if one of the angles (let's say A) increases, it implies that the other angle (B) must decrease in order to maintain the sum as a constant. Conversely, if A decreases, B must increase. This negative relationship between the two angles implies that they are negatively correlated.
Therefore, the correlation between two angles in a random triangle is negative. This means that as one angle increases, the other angle decreases, and vice versa.

The probability that pete will catch fish when he goes fishing is .8. pete is going to fish 3 days next week. define the random variable x to be the number of days pete catches fish. the probability that pete will catch fish on exactly one day is
Answers
Final answer:
The random variable X is defined as the number of days Pete catches fish. The probability that Pete will catch fish on exactly one day is 0.096.
Explanation:
The random variable X is defined as the number of days Pete catches fish when he goes fishing.
To find the probability that Pete will catch fish on exactly one day, we can use the binomial probability formula. The formula is:
P(x) = (n C x) * p^x * (1-p)^(n-x)
where n is the number of trials (in this case, 3 days), x is the number of successes (in this case, 1 day), and p is the probability of success (in this case, 0.8).
Plugging in the values, we get:
P(x = 1) = (3 C 1) * 0.8^1 * (1-0.8)^(3-1) = 3 * 0.8 * 0.2^2 = 0.096
If we put five math, six biology, eight history, and three literature books on a bookshelf at random, what is the probability that all the math books are together?
Answers
The probability that all the math books are together can be calculated by considering the number of ways the math books can be arranged together and dividing it by the total number of ways all the books can be arranged.
Explanation:The probability that all the math books are together can be calculated by considering the number of ways the math books can be arranged together and dividing it by the total number of ways all the books can be arranged.
First, calculate the total number of ways the books can be arranged on the bookshelf. Since there are 22 books in total, the number of arrangements is 22!.
Next, calculate the number of ways the math books can be arranged together. Since there are 5 math books, the number of arrangements is 5!.
Finally, divide the number of arrangements of the math books by the total number of arrangements to find the probability. So the probability is 5! / 22!.
