Step-by-step explanation:

We will have a Deficit balance of $30 at the end of the month.

"Unilateral transfer" is the term used to describe the balance of payments deficit's most obvious cause. For instance, Americans who contribute money to another country in the form of foreign aid do not receive anything in return (economically speaking). Few economists would argue that foreign aid-related balance of payment deficits are a "bad thing."

Weekly net income = $380

Monthly net income = $380 * 4 weeks = $1520.

Monthly expenses = $1550

Balance = Monthly income - monthly expenses = $-30.

The negative sign shows a deficit of $30 monthly

Therefore, We will have a Deficit balance of $30 at the end of the month.

Answer:

8

Step-by-step explanation:

In order to answer this question we need to find the greatest common divisor of the two quantities which will give us the maximum number by which both can be divided.

The greatest common divisor of a group of integers is the largest common divisor that divides each of the integers. The first step to find it is write down the integers as a product of primes, so we have:

\(56=(28)(2)=(14)(2)(2)=(7)(2)(2)(2)= 2^3\)·\(7\)

\(72=(24)(3)=8(3)(3)=2^3\)·\(3^2\)

Now, in order to find the gcd we are going to take the factors that they have in common. In this case they both share the \(2^3\).

Thus, \(2^3=8\) is the greatest common divisor and therefore the maximum value of weight which can measure the weight of the rice exact number of times.

Answer:

the inverse of the function f^-1(x)=(x-3)/(4+5x)

Step-by-step explanation:

( 3+4x)/(1-5x)

y=4x+3/1-5x swap the variables

x=4y+3/1-5y solve for y

y=x-3/4+5x

The inverse of a function is :y=x-3/4+5x

What is inverse of a function?

The inverse function returns the original value for which a function gave the output.

If you consider functions, f and g are inverse, f(g(x)) = g(f(x)) = x. A function that consists of its inverse fetches the original value.

Steps are:

for example:

Suppose, f(x) = 2x + 3 is a function.

Let f(x) = 2x+3 = y

y = 2x+3

x = (y-3)/2 = f-1(y)

This is the inverse of f(x).

Given function:

f(x)= ( 3+4x)/(1-5x)

now, swap the variables x and y.

y=4x+3/1-5x

Now solving for y

x=4y+3/1-5y

y=x-3/4+5x

Hence, the inverse of the function f^-1(x)=(x-3)/(4+5x).

The depth of the water in the cone-shaped tank is increasing at a rate of approximately 1.385 meters per second.

To determine the rate at which the depth of the water is changing, we can use related rates. Let's denote the depth of the water as h(t), where t represents time. We are given that dh/dt (the rate of change of h with respect to time) is 12 m/sec, and we want to find dh/dt when h = 18 meters.

To solve this problem, we can use the volume formula for a cone, which is V = (1/3)πr^2h, where r is the base radius and h is the depth of the water. We can differentiate this equation with respect to time t, keeping in mind that r is a constant (since the base radius does not change).

By differentiating the volume formula with respect to t, we get dV/dt = (1/3)πr^2(dh/dt). Now we can substitute the given values: dV/dt = 12 m/sec, r = 26 meters, and h = 18 meters.

Solving for dh/dt, we have (1/3)π(26^2) (dh/dt) = 12 m/sec. Rearranging this equation and solving for dh/dt, we find that dh/dt is approximately 1.385 meters per second. Therefore, the depth of the water in the tank is increasing at a rate of about 1.385 meters per second.

To derive the least-squares fit for the model y = a1x + a2x^2 with a zero intercept, we need to minimize the sum of squared residuals. Let's denote the observed data points as (xi, yi) for i = 1 to n.

The objective is to find the values of a1 and a2 that minimize the following sum of squared residuals:

SSR = ∑(yi - (a1xi + a2xi^2))^2

To find the minimum, we differentiate SSR with respect to a1 and a2 separately and set the derivatives equal to zero.

Partial derivative with respect to a1:

∂SSR/∂a1 = -2∑(yi - (a1xi + a2xi^2))*xi = 0

Partial derivative with respect to a2:

∂SSR/∂a2 = -2∑(yi - (a1xi + a2xi^2))*xi^2 = 0

Expanding the above equations:

∑(yixi) - a1∑(xi^2) - a2∑(xi^3) = 0 ------ (1)

∑(yixi^2) - a1∑(xi^3) - a2∑(xi^4) = 0 ------ (2)

Now, let's solve these equations to find the values of a1 and a2.

From equation (1):

a1∑(xi^2) + a2∑(xi^3) = ∑(yi*xi) ------ (3)

From equation (2):

a1∑(xi^3) + a2∑(xi^4) = ∑(yi*xi^2) ------ (4)

We can express equations (3) and (4) in matrix form as:

| ∑(xi^2) ∑(xi^3) | | a1 | = | ∑(yixi) |

| ∑(xi^3) ∑(xi^4) | | a2 | = | ∑(yixi^2) |

Solving this system of linear equations will give us the values of a1 and a2.

Once a1 and a2 are determined, we have the least-squares fit of the model y = a1x + a2x^2 with a zero intercept.

A polynomial regression model is a good choice for this data, as it can fit the trend of increasing population growth over time.

A function is a mathematical concept that assigns a unique output value for each input value.

In mathematical notation, a function is usually expressed as "f(x)" where "x" is the input and "f(x)" is the corresponding output. For example, a function could be defined as f(x) = x^2, which means that for any value of x, the function will calculate and return the square of that value.

To model the world population data, we can use a mathematical function to fit the data points. A polynomial regression model is a good choice for this data, as it can fit the trend of increasing population growth over time.

Answer:

6. (a) No Mr Lee did not order the correct amount of milk.

(b)Mr Lee should have ordered for 48 pints of milk.

7. 156 pints sized jars

8. Eilleen's gallon can hold more cups that James's 3 quart water bottle.It can hold 4 more cups

Step-by-step explanation:

6. There are 96 fourth graders and each is supposed to get 1 cup of milk.

Hence, the number of cups of milk for all the fourth graders at the party is

96 × 1 cup of milk = 96 cups of milk.

Mr. Lee ordered 45 pints of milk for the fourth - grade party.

We have the conversion rate:

1 cup = 0.5 pints

Hence

1 cup = 0.5 pints

96 cups of milk = x

Cross Multiply

1 cup × x = 96 cups of milk × 0.5 pints

x = 96 cups of milk × 0.5 pints/1 cup

x = 48 cups of milk

a. Did Mr. Lee order the correct amount of milk?

No Mr Lee did not order the correct amount of milk.

b. if so, explain why you think he is correct. if not, how many pints of milk should he have ordered?

Mr Lee should have ordered for 48 pints of milk.

7. Daphne and Jordan made jam to sell at the market. Their jam is sold in pint - size jars.

They made 137 quarts but only sold 59 quarts.

The amount of quarts left is calculated as: 137 quarts - 59 quarts

= 78 quarts

We have conversion rate of

1 quart = 2 pints

The number of pint - size jars that are left is calculated as:

1 quart = 2 pints

78 quarts = x

Cross Multiply

1 quart × x = 78 quarts × 2 pints

x = 78 quarts × 2 pints/1 quart

x = 156 pints

The number of pint - size jars that are left 156 pints

8.

For James

James had a 3-quart water bottle.

1 quart = 4 cups

3 quarts = x

Cross Multiply

1 quart × x = 3 quarts × 4 cups

x = 3 quarts × 4 cups/1 quart

x = 12 cups

Hence, James 3 quart water bottle can hold 12 cups

For Eileen

Eileen bought 1-gallon jug.

1 gallon = 16 cups

Hence, Eileen's gallon can hold 16 cups

The difference between both containers is:

16 cups - 12 cups = 4 cups

Therefore, Eileen's gallon can hold more cups that James's 3 quart water bottle

It can hold 4 more cups

Answer: 80°; the supplementary angle to the 30° angle and ∠1 is a corresponding angle to the 70° angle this means that the supplementary angle to the 30° angle and ∠1 is a 70° angle therefore 30°+m ∠1+ 70° equals 180°. So, m ∠1= 180°.

Step-by-step explanation:

The measure of angle 1 should be 80 degrees.

Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two two angles are two pairs of supplementary angles.

Then its meaning; supplementary angles are aligned adjacent to each other, and their exterior sides will make a straight line.

The supplementary angle to the 30° angle and ∠1 is a corresponding angle to the 70° angle which means that the supplementary angle to the 30° angle and ∠1 is a 70° angle.

Therefore 30° + m ∠1 +  70° = 180°.

100 + m ∠1= 180°.

So, m ∠1= 80°.

The situations that can be modeled by uniform distribution include;

Option 2) is: When each discrete value is

equally likely to occur.

Option 3) is:  When each value of a continuous random variable is equally likely to occur.

Since each value has an equal chance of occurrence, thus this situation can be  modelled by Uniform distribution.

Since each value of a continuous random variable is equally likely to occur, that it follows a continuous uniform distribution.

A uniform distribution is a type of probability distribution in statistics in which all outcomes are equally likely. A deck of cards has uniform distributions because the chances of drawing a heart, a club, a diamond, or a spade are all equal. When you sample a random element, you do so according to some distribution.

The term "uniformly" refers to sampling from a uniform distribution, i.e., from a set in which drawing each element is equally likely. In statistics, it is a type of probability distribution in which every possible outcome has an equal chance of occurring. Because each variable has an equal chance of being the outcome, the probability is constant.

The range is the most convenient measure of dispersion because it is simple to calculate and understand. The range is the most imprecise measure of variability because can be greatly affected by outliers or extreme values and may not accurately reflect the true variability of the data.

The range is used to evaluate a small data set such as the grades of a small group of students.

The range is the difference of the maximum and minimum values of a data set. The range is calculated by subtracting the smallest value from the largest value in a data set.

For example, if the smallest value in a data set is 2 and the largest value is 10, the range would be 8 (10-2=8).

However, the range is also the most imprecise measure of variability because it only takes into account the two extreme values in the data set and does not consider the values in between.

The range is most useful when you want to quickly assess the dispersion of a data set or when the data set is small and does not have any outliers. It is also useful when you want to compare the dispersion of two or more data sets. However, if the data set is large or has outliers, it is better to use other measures of dispersion and variability, such as the standard deviation or interquartile range.
