The expected number of attempts at taking out gloves individually from the drawer till you find both sides (left hand and right hand) of gloves is n.

To find the expected number of attempts at taking out gloves individually from the drawer till you find both sides (left hand and right hand) of gloves we can use the principle of geometric distribution. The geometric distribution is a probability distribution that represents the number of trials required to obtain the first success in repeated Bernoulli trials where each trial has a constant probability of success.To find the expected number of attempts at taking out gloves individually from the drawer till you find both sides (left hand and right hand) of gloves we have to first determine the probability of finding the first glove. Since the drawer has an infinite number of gloves, the probability of finding a left glove or a right glove is 1/2. Thus, the probability of finding the first glove is 1. Now, we have to find the probability of finding the matching glove of the first glove. The probability of this is 1/n, where n is the total number of gloves in the drawer. Thus, the probability of finding both the left glove and the right glove is given by the product of the probability of finding the first glove and the probability of finding the matching glove. This is given by 1 x 1/n or 1/n. Therefore, the expected number of attempts at taking out gloves individually from the drawer till you find both sides (left hand and right hand) of gloves is given by the formula E(X) = 1/p, where p is the probability of finding both the left glove and the right glove. Thus, E(X) = 1/(1/n) = n.

We are told that  Jeanette uses 18 square inches of paper for each card, for us to get the number of square inches she will need to make 150 cards, we will use the equality operation;

18 in² = 1 card

x in² = 150 cards

cross multiply

x * 1 = 18*150

x = 2700 in²

Convert 2700 in² to feet²

Since 1in² = 0.00694444ft²

2700in² = x

cross multiply

x = 2700 * 0.00694444

x = 18.749988ft²

Hence she will] need 18.749988ft²  to make 150 cards

The rate at which the distance between the man and the plane is increasing when the plane passes over the radio tower is approximately 519.92 ft/sec.

Let's denote the distance between the man and the plane as x and the time elapsed since the plane passes over the radio tower as t. We are given that the plane is flying horizontally away from the man, so the height of the plane remains constant at 5000 ft.

We can set up a proportion based on the similar triangles formed by the man, the plane, and the tower:

x / 12000 = 5000 / t

Cross-multiplying, we have:

xt = 12000 * 5000

xt = 60,000,000

Now, we can differentiate both sides of the equation with respect to time t:

d(xt)/dt = d(60,000,000)/dt

dx/dt * t + x * dt/dt = 0

dx/dt * t + x * 1 = 0

dx/dt = -x/t

We are given that the plane is flying at a rate of 520 ft/sec, so dx/dt = 520 ft/sec.

At the moment the plane passes over the radio tower, the distance x is 12000 ft. We can substitute these values into the equation to find the rate at which the distance between the man and the plane is increasing:

520 = -12000 / t

Solving for t:

t = -12000 / 520 = -23.08 sec (approximately)

Since time cannot be negative, we discard the negative value and take the positive value of t.

Now, we can substitute the value of t into the equation to find dx/dt:

dx/dt = -x / t = -12000 / (-23.08) = 519.92 ft/sec (approximately)

Therefore, the rate at which the distance between the man and the plane is increasing when the plane passes over the radio tower is approximately 519.92 ft/sec.

The rate of change of temperature at the origin in the direction of the unit vector u = (3,-5) can be determined by T = r² + s².

A. To calculate the size of the tower bounded by the plane z = 0 and the paraboloid z = 1 - x² - y², we can use a double integral in polar coordinates. By expressing the paraboloid equation in polar coordinates, we can set up the integral and evaluate it to find the size of the tower.

B. Differential equation models are mathematical representations used to describe various real-life phenomena. For the given examples:

The free-falling stone can be modeled using Newton's second law and the concept of acceleration due to gravity.

The vertical displacement of a spring can be described using Hooke's law and the properties of springs.

Kirchhoff's Second Law, also known as the voltage law, can be used to model the behavior of electrical circuits.

Newton's Law of Cooling is a differential equation that describes the rate of change of temperature of an object as it loses heat to its surroundings.

Growth and decay phenomena, such as population growth or radioactive decay, can be modeled using exponential or logarithmic functions.

C. To calculate the rate of change of temperature at the origin in the direction of the unit vector u = (3,-5), we need to find the gradient of the temperature function T = r² + s². The gradient represents the direction of the steepest increase in a function. By computing the gradient at the origin and taking the dot product with the unit vector u, we can determine the rate of change of temperature in the desired direction.

The mean of T is -10 and the standard deviation of T is √425 when X1 and X2 are independent.

To find the mean of T, we can use the properties of expected values. Since T = 11X1 - 2X2, the mean of T can be calculated as follows: E(T) = E(11X1) - E(2X2) = 11E(X1) - 2E(X2) = 11(10) - 2(20) = -10. To find the standard deviation of T, we need to consider the variances and covariance of X1 and X2. Since X1 and X2 are independent, the covariance between them is zero. Therefore, Var(T) = Var(11X1) + Var(-2X2) = 11^2Var(X1) + (-2)^2Var(X2) = 121(2^2) + 4(3^2) = 484 + 36 = 520. Thus, the standard deviation of T is √520, which simplifies to approximately √425. When X1 and X2 have a correlation of -0.76, the mean and standard deviation of T remain the same as in the case of independent variables. To calculate the probability P(T > 30) when X1 and X2 are independent, normally distributed variables, we need to convert T into a standard normal distribution. We can do this by subtracting the mean of T from 30 and dividing by the standard deviation of T. This gives us (30 - (-10))/√425, which simplifies to approximately 6.16.  We can then look up the corresponding probability from the standard normal distribution table or use statistical software to find P(T > 30). The probability will be the area under the standard normal curve to the right of 6.16.

Answer:

i dont understand what you're trying to say but 16 * 25 = 400

1. The monthly payment of the 5-year loan is approximately $2,225.77.

2. The equivalent uniform annual cost for the tractor is approximately $5,572.50.

1. To calculate the monthly payment of a loan, we can use the formula for an amortizing loan. The formula is:

PMT = P * (r * (1 + r)^n) / ((1 + r)^n - 1)

Where:

PMT = Monthly payment

P = Principal amount (loan amount)

r = Monthly interest rate (annual interest rate divided by 12)

n = Total number of payments (number of years multiplied by 12)

In this case, the principal amount (P) is $100,000, the annual interest rate is 12%, and the loan duration is 5 years.

r = 12% / 12 = 1% per month

n = 5 years * 12 months/year = 60 months

PMT = 100,000 * (0.01 * (1 + 0.01)^60) / ((1 + 0.01)^60 - 1)

PMT ≈ $2,225.77

Therefore, the monthly payment of the 5-year loan is approximately $2,225.77.

2. To calculate the equivalent uniform annual cost, we need to consider the initial cost of the tractor, salvage value, maintenance costs, and the interest rate.

The equivalent uniform annual cost (EUAC) can be calculated using the formula:

EUAC = (Initial cost - Salvage value) + (Annual maintenance cost * Present worth factor)

The present worth factor can be calculated using the formula:

Present worth factor = (1 - (1 + r)^-n) / r

Where:

r = Interest rate (10%)

n = Number of years (10 years)

EUAC = ($7,500 - $5,000) + ($500 * ((1 - (1 + 0.10)^-10) / 0.10))

EUAC = $2,500 + ($500 * ((1 - 0.3855) / 0.10))

EUAC ≈ $2,500 + ($500 * 6.145)

EUAC ≈ $2,500 + $3,072.50

EUAC ≈ $5,572.50

Therefore, the equivalent uniform annual cost for the tractor is approximately $5,572.50.

Step-by-step explanation:

The numbers differing by 42 whose product is as small as possible are (- 21 + √(441 + p)) and (- 21 - √(441 + p)).

Let us suppose the numbers to be x and y.

As per the given information, we can write;

xy = p ---- (1)

We have to find two numbers differing by 42 whose product is as small as possible.

If two numbers are differing by 42; then we can say

x - y = 42 ---- (2)

From equation (2), we can say

x = y + 42

Now, substitute the value of x in equation (1), we get;

xy = p(y + 42)y² + 42y - p

= 0

Solving this quadratic equation, we will get;

∆ = 1764 + 4p

∴ y = (- 42 ± √(1764 + 4p)) / 2

Now, to find the minimum value of xy, we need to find the value of y that makes xy minimum.

Therefore, the two numbers that make xy as small as possible are;

y = (- 42 + √(1764 + 4p)) / 2

and

x = y + 42

So, the two numbers are;

y = (- 42 + √(1764 + 4p)) / 2

and

x = y + 42

The correct option is c.) swimsuit sales throughout the year; sunscreen sales throughout the year.

Correlation coefficient is a measure of the strength and direction of a relationship between two variables. The correlation coefficient varies from -1 to +1. A correlation of -1 means that a negative association between two variables is perfect, while a correlation of +1 means that there is a positive association between two variables that is perfect. The closer the correlation coefficient is to 0, the weaker the association between two variables is. A correlation coefficient of 0 means that there is no relationship between two variables.From the given options, the data set that is most likely to have a negative association and a correlation coefficient between 0 and -1 is (c) swimsuit sales throughout the year and sunscreen sales throughout the year.The reason behind this is that when it's summer or a hot season, people tend to buy more swimsuits than sunscreen. And when it's winter or a cold season, people tend to buy more sunscreen than swimsuits. Hence, the correlation coefficient between swimsuit sales throughout the year and sunscreen sales throughout the year is most likely to be between 0 and -1 because there is an inverse relationship between these two variables.
