The temperature cooled by 4° on the first day of the year together on the 1st 2 days of the year the temperature heated up 7°. What is the Temperature on tue second day?

Answer: 40 years old.

Step-by-step explanation:

Let man's age = a

Let son's age = b

Since a man is 4 times as old as his son, therefore

a= 4b

In 5 years, he will only be 3 times as old as his son, therefore

a+5=3(b+5)

Apply substitution method :

4b+5=3b+15

b=10

a=40

The mean absolute deviation is 0.75

To calculate the mean absolute deviation (M.A.D.), you need to find the average of the absolute differences between each data point and the mean of the data set

From the information given, we have that the data set is;

8 9 9 7 8 6 9 8

Let's calculate the mean, we get;

Mean = (8 + 9 + 9 + 7 + 8 + 6 + 9 + 8) / 8

Mean = 64 / 8

Divide the values

Mean = 8

Let's determine the absolute difference, we get;

Absolute differences=

|8 - 8| = 0

|9 - 8| = 1

|9 - 8| = 1

|7 - 8| = 1

|8 - 8| = 0

|6 - 8| = 2

|9 - 8| = 1

|8 - 8| = 0

Find the mean of the absolute differences:

Average of absolute differences = (0 + 1 + 1 + 1 + 0 + 2 + 1 + 0) / 8

Absolute difference = 6 / 8 = 0.75

The dimensions of the garden that create the maximum area are 5 meters by 15 meters, and the maximum possible area is 75 square meters

What is measurement?

Measurement is the process of assigning numerical values to physical quantities, such as length, mass, time, temperature, and volume, in order to describe and quantify the properties of objects and phenomena.

Let's assume that the rock wall is the width of the garden and the wire fencing is used for the length and the other two sides. Let's denote the length of the garden as L and the width as W.

Since we have 30 meters of fencing available, the total length of wire fencing used is:

L + 2W = 30 - W

Simplifying this equation, we get:

L = 30 - 3W

The area of the garden is:

A = LW

Substituting the expression for L from the previous equation, we get:

A = W(30 - 3W)

Expanding the expression, we get:

A = 30W - 3W²

To find the maximum area, we need to take the derivative of A with respect to W and set it equal to zero:

dA/dW = 30 - 6W = 0

Solving for W, we get:

W = 5

Substituting this value back into the expression for L, we get:

L = 15

Therefore, the dimensions of the garden that create the maximum area are 5 meters by 15 meters, and the maximum possible area is:

A = 5(15) = 75 square meters

Rick would need to have at least 100 cars on hand to immediately be able to deliver any car (model, option package, color).

To immediately deliver any car, Rick Rich's dealership must have all possible combinations of Mercedes models, option packages, and colors in stock.

With five models, four option packages, and five colors, there are 5 x 4 x 5 = 100 possible combinations.

Therefore, Rick would need to have at least 100 cars on hand, each representing a unique combination of model, option package, and color. It's worth noting that having exactly 100 cars on hand would only allow Rick to deliver one of each possible combination, so it may be prudent to have additional inventory on hand to meet demand for more popular combinations.

Aisha has 15 points

Let's use the given information to set up an equation to represent the relationship between the points each friend has.

Let x be the number of points Aisha has.

Then, according to the problem statement, we know that:

Carter has 7 1/2 more points than Aisha, so he has

x + 7 1/2 points.

Jamila has 4 - 1/2 more points than Carter, so she has

x + 7 1/2 + 4 - 1/2 points,

which simplifies to x + 11 points.

Jamila has 26 points, so we can set x + 11 equal to 26 and solve for x:

x + 11 = 26

x = 26 - 11

x = 15

The formula for calculating the mean of a probability distribution is mean = (x * P(x)), where x denotes a potential result and P(x) denotes its probability.

Distribution of Probabilities F(x) = P (X x) is a formula that describes it. Additionally, if the interval (a, b) is semi-closed, the probability distribution function is provided by the equation P(a X b) = F(b) - F (a). The range of a random variable's probability distribution function is always from 0 to 1.

Therefore, the mean for this distribution is: (0 * 0.04) + (1 * 0.24) + (4 * 0.35) + (5 * 0.16) + (7 * 0.21). mean = 0 + 0.24 + 1.4 + 0.8 + 1.47 mean = 4.81

Standard deviation = ((x - mean)2 * P(x)), where x is a conceivable outcome and P(x) is the probability of that outcome, gives the standard deviation of a probability distribution.

This gives us the following standard deviation for this distribution: standard deviation = ((((0 - 4.81)2 * 0.04) + ((1 - 4.81)2 * 0.24) + ((4 - 4.81)2 * 0.35) + ((5 - 4.81)2 * 0.16) + ((7 - 4.81)2 * 0.21)) (23.0461) 4.8114 is the standard deviation.

To two decimal places, round:

mean = 4.81 4.81 is the standard deviation.

The limit is equal to\(\(\frac{7^a \ln(7)}{3^a \ln(3)}\)\) using L'Hôpital's Rule.

To evaluate the limit using L'Hôpital's Rule, we can take the derivative of the numerator and denominator with respect to x and then evaluate the limit again. Let's proceed with the calculation:

We have the limit:

\(\[ \lim_{x \to a} \frac{7^x - 1}{3^x - 1} \]\)

Taking the derivative of the numerator and denominator, we get:

\(\[ \lim_{x \to a} \frac{ \frac{d}{dx}(7^x - 1) }{ \frac{d}{dx}(3^x - 1) } \]\)

Differentiating, we have:

\(\[ \lim_{x \to a} \frac{7^x \ln(7) - 0}{3^x \ln(3) - 0} \]\)

Simplifying, we get:

\(\[ \lim_{x \to a} \frac{7^x \ln(7)}{3^x \ln(3)} \]\)

Now we can evaluate the limit by plugging in the value of x approaching a:

\(\[ \lim_{x \to a} \frac{7^a \ln(7)}{3^a \ln(3)} = \frac{7^a \ln(7)}{3^a \ln(3)} \]\)

Therefore, the limit is equal to\(\(\frac{7^a \ln(7)}{3^a \ln(3)}\)\) using L'Hôpital's Rule.

Thanh's cost per month (four weeks) will be $300.00.The given fixed rate for Thanh is $49.00 per week. Thanh also pays $14.00 per week for the optional insurance and $12.00 weekly on gas.

To find Thanh's cost per month (four weeks), we need to multiply his weekly cost by 4.We can use the formula below to calculate Thanh's monthly cost.

Total weekly cost = Fixed rate + Insurance cost + Gas cost

Total weekly cost = $49.00 + $14.00 + $12.00

Total weekly cost = $75.00

The cost for Thanh per month (four weeks) = Total weekly cost × 4

Cost for Thanh per month (four weeks) = $75.00 × 4

Cost for Thanh per month (four weeks) = $300.00

Based on the calculations using unit pricing, Toilet paper B has a lower unit price and is the better deal between the two. Customers will save more money if they purchase toilet paper B rather than toilet paper A because the price per mega roll is lower. (option b)

Saving money while shopping is one of the best ways to reduce your expenses and have more disposable income for other things. Unit pricing is a pricing system that displays prices in standard units, allowing customers to compare prices across different brands and package sizes and save money. To determine which toilet paper deal is better, we can use the unit price method, which divides the price by the number of units in the package. The toilet paper with the lower unit price is the better deal.
The formula for unit pricing is as follows:
Unit price = total price ÷ number of units
Using the above formula, we can calculate the unit price of toilet paper A and toilet paper B as follows:
For Toilet paper A:
Unit price = $4.59 ÷ 6 mega rolls
Unit price = $0.765 per mega roll
For Toilet paper B:
Unit price = $9.02 ÷ 12 mega rolls
Unit price = $0.751 per mega roll
Therefore, based on the calculations, Toilet paper B has a lower unit price and is the better deal between the two. Customers will save more money if they purchase toilet paper B rather than toilet paper A because the price per mega roll is lower. (option b)
Unit pricing is a great way to compare prices, and consumers should always use it to determine the better deal between two products, as this will help them save money and stick to their budget.
