Step-by-step explanation:

You first convert 2  3/4 into 2 9/12. And then you convert 3  1/3 into  3 4/12. Now both of these have the same denominator so you can add. When you add your answer should be 6  1/12

Answer:

x ---- y

1 ---- 3

4 ---- 12

6 ---- 18

Step-by-step explanation:

Given

\(y = 3x\)

Required

Create a table that represents this scenario

Because x represents time, x can not be negative. So, the domain of x is:

\(x \geq 0\)

Assume \(x = 1\)

\(y = 3 * 1 = 3\)

Assume x = 4

\(y=3*4 = 12\)

Assume x = 6

\(y=3*6 = 18\)

Hence, the table is:

x ---- y

1 ---- 3

4 ---- 12

6 ---- 18

The required total cost of all the purchases is $7,930.00. Option C is correct.

Given that,
Al Roy bought five bonds of Jort Co. 11 3/4 at 93.25% and four bonds of Inst. System 12x08 for 81.125%, the commission on the bonds is $2.50 per bond.

Given,

Each side of the lower triangle is 16m.

So, the triangle is an equilateral triangle.

We know,  for the equilateral triangle

Area = \(\sqrt{3} /4 * side^{2}\)

So, the area of the triangle is = \(\sqrt{3} /4 *16^{2}\) = \(64\sqrt{3}\) \(m^{2}\)

Now,

There are two half circles on the triangle

We know the side of the triangle is 16m.

So, the diameter of each half-circle is 8m

So Raidus = 4m

Now we know the area of a half circle = \(1/2 * \pi * r^{2}\)

So, each of the half circles has the area = \(1/2 * \pi * 4^{2}\) = \(8\pi\)\(m^{2}\)

Now, the area of the whole object is

= Area of the Triangle + (2 * Area of one half circle)

= [\(64\sqrt{3}\) + (\(2 * 8\pi\))] \(m^{2}\)

= 161.088 \(m^{2}\) (Considering, \(\sqrt{3} = 1.732\) & \(\pi = 3.14\))

Now,

We know,

Circumference of half circle = \(\pi r\)

So, the Circumference of each of the half circle = \(\pi *4\) = \(4\pi\)m

Now,

The perimeter of the whole object

= Two sides of the triangle + (2 * circumference of each circle)

= 16+16+ (2 * \(4\pi\))

= 57.12 m (Considering \(\pi =3.14\))

Therefore, The area of the whole object is \(161.088 m^{2}\) and the perimeter of the whole object is \(57.12 m\).

Circumference is the distance around the edge or perimeter of a circular object. In other words, it is the length of the curved line that forms the boundary of the circle. The circumference of a circle is calculated by multiplying the diameter of the circle (the distance across the widest part of the circle) by the mathematical constant pi (π), which is approximately equal to 3.14159. The formula for calculating the circumference of a circle is C = 2πr, where C is the circumference, π is the mathematical constant pi, and r is the radius of the circle (the distance from the center of the circle to its edge).

If Given f(x) = 1/2 (3 - x) ^ 2 , the value of f(15) is 72.

What is function?

In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range. In simpler terms, a function is a set of rules that takes an input value and produces a corresponding output value.

The given function is:

f(x) = 1/2 (3 - x)²

To find the value of f(15), we need to substitute 15 for x in the function:

f(15) = 1/2 (3 - 15)²

Here, we subtract 15 from 3 to get -12 in the parentheses, and then we square it to get 144. We can simplify the expression further by multiplying 144 by 1/2, which gives us 72:

f(15) = 1/2 (144)

f(15) = 72

Therefore, the value of f(15) is 72.

Answer: 1.2kg pack of carrots for $1

Step-by-step explanation:

To compare the two deals, we need to calculate the price per kilogram for each option.

For the first option, the price per kilogram is:

1 pack of 1.2kg carrots for $1

Price per kilogram = $1 ÷ 1.2kg = $0.83/kg

For the second option, the price per kilogram is:

1 bag of 700g carrots for $0.77

Price per kilogram = $0.77 ÷ (700g ÷ 1000g/kg) = $1.10/kg

Therefore, the better deal is the 1.2kg pack of carrots for $1, as it has a lower price per kilogram ($0.83/kg) compared to the 700g bag for $0.77 ($1.10/kg).

Answer:

The probability that the student chosen at random was male OR got an "A" is 31/58.

To find the probability that the student was male OR got an "A," we need to calculate the probability of each event separately and then add them together.

Let's calculate the probability of the student being male:

Total number of males = 11

Total number of students = 58

Probability of the student being male = Number of males / Total number of students = 11/58

Now, let's calculate the probability of the student getting an "A":

Total number of students who got an "A" = 20

Probability of the student getting an "A" = Number of students who got an "A" / Total number of students = 20/58

To find the probability of the student being male OR getting an "A," we add the two probabilities together:

Probability (Male OR A) = Probability (Male) + Probability (A) = 11/58 + 20/58 = 31/58

Therefore, the probability that the student chosen at random was male OR got an "A" is 31/58.

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

Total water bill for the month is $62.37.

It seems that you may have accidentally left out the total amount of your water bill.

The total amount by simply adding the amounts of the individual bills together:

Total water bill =\($36.34 + $26.03\)

= \($62.37\)

You have not provided enough information to determine your total water bill.

You have only given the amounts of your individual bills from Metro Water Services and Madison Suburban Utility District.

To find your total water bill, you simply need to add the two bills together.

So, the total amount you owe for water this month would be:

Total water bill = \($36.34 + $26.03\)

= \($62.37\)

It appears that you may have forgotten to include the full amount of your water bill by accident.

Simple addition of the separate bill amounts yields the following sum:

Water bill total = \($36.34 + $26.03\)

= \($62.37\)

Your total water bill cannot be calculated because not enough information has been given.

Only the amounts of your individual Metro Water Services and Madison Suburban Utility District bills have been provided.

You just need to combine the two invoices together to get your total water bill.

As a result, this month's total water bill for you would be:

Water bill total =  \($36.34 + $26.03\)

= \($62.37\)

Answer:

d. The administrators are unable to tell if there is a true difference between Oklahoma and non-Oklahoma residents in their excitement to go home for the holidays because their interval covers 0.

Step-by-step explanation:

The confidence interval refers to a rabje of statistically calculated values used in establishing a certain level of confidence in the outcome of a data.

The confidence interval is calculated thus :

Mean ± (Zcritical * Error)

The ± sign ensures we have the lower and upper boundary of our confidence level.

From the confidence level given in the question : -1.78 to 3.27

Since 0 is contained in the confidence interval range given, then it can be concluded that the difference in excitement between Oklahoma and non oklahoma residents cannot be adequately established.

Answer: A tangent to the x-axis means that the y-coordinate of the point of tangency is 0. So, we can find the possible values of d by setting y = 0 and solving for x:

0 = x^3/3 + 7x^2/2 + 10x + d

This is a cubic equation, so it can be solved using various methods such as factoring, completing the square, or using a numerical method such as the Newton-Raphson method. If the equation can be factored or the method used is numerical, there might be multiple possible values of d. If the method used is completing the square, there would be only one possible value of d.

However, without a specific method, it's not possible to find the exact value(s) of d. The possible values of d will depend on the specific solution method used to solve the equation.

The maximum number of tickets an airline should sell on a flight with 300 seats so that it can be approximately 99% confident that all ticket holders who do show up will be able to board the plane is 324.

The maximum number of tickets an airline should sell on a flight with 300 seats so that it can be approximately 99% confident that all ticket holders who do show up will be able to board the plane is 326.   This is calculated using the 1/2-value correction (de Moivre-Laplace Approximation). The 1/2-value correction assumes the normal distribution is symmetric, with the mean in the middle of the distribution. This means that the probability of being above the mean is equal to the probability of being below the mean.  Since the airline wants to be 99% confident that all ticket holders who do show up will be able to board the plane, this means that the airline needs to sell enough tickets such that the probability of being above the mean (300 tickets sold) is 99%.   Using the 1/2-value correction, the airline needs to sell 326 tickets to achieve this confidence level.

This is calculated as follows:   P(x > 300) = 0.99  P(x < 300) = 0.01  Using the 1/2-value-correction:

P(x = 300 + 0.5) = 0.99

Therefore,   x = 300 + 0.5=>  x = 300.5 => x = 326

The sample size for the Gallup poll is 1,627 adults. The 95% confidence interval for those who say they felt fully engaged with their mortgage provider is approximately 22.0% (rounded to 1 decimal place).

To calculate the 95% confidence interval, we need to consider the margin of error. The margin of error is given as 2.5%, which means that we need to account for plus or minus 2.5% around the observed proportion of 22%.

First, let's calculate the margin of error:

Margin of Error = 2.5% of 22% = 0.025 * 22% = 0.0055

Next, we can calculate the lower and upper bounds of the confidence interval:

Lower Bound = 22% - Margin of Error = 22% - 0.0055 = 21.995% ≈ 22.0%

Upper Bound = 22% + Margin of Error = 22% + 0.0055 = 22.005% ≈ 22.0%

Therefore, the 95% confidence interval for those who say they felt fully engaged with their mortgage provider is approximately 22.0% (rounded to 1 decimal place).
