can someone help with this question. it would be greatly appreciated.

Final answer:

To estimate the sum of 3389 and 2712, round each number to the nearest thousand (3389 to 3000 and 2712 to 3000) and then add them to get an estimated sum of 6000.

Explanation:

To make an estimate for the sum of 3389 and 2712, you can round each number to the nearest hundred or thousand then add the rounded numbers. In this case, let's round to the nearest thousand for a simpler estimate:

Now add the rounded numbers:

3000 + 3000 = 6000

The number model for this estimate strategy is:

\( 3000 + 3000 = 6000 \)

This model shows the process of rounding each term to the nearest thousand and then adding them together to get an estimated sum.

There is no number between 17 and 22 that has prime factors of 2 and 5 because the products of these numbers or their powers don't fall within the range of 17 and 22.

The question is asking for a number that is between 17 and 22 and has prime factors of 2 and 5. Since 2 and 5 are prime numbers, their products could be solutions. However, the least product of 2 and 5 is 10 which is not between 17 and 22. If we consider the product of the power of these numbers such as 2² = 4 and 5² = 25, still we don't have a number that falls within the 17 and 22 range. Therefore, there is no number that is between 17 and 22 that has prime factors of 2 and 5.

Answer: There are 768 hours in 72 days.

Step-by-step explanation:

Given: The number of hours in 25 days = [tex]266\frac{2}{3}=\frac{800}{3}[/tex] hours

Let x be the number of hours in 72 days.

Since the relation between number of hours and days is directly proportional, thus

[tex]\frac{x}{72}=\frac{\frac{800}{3}}{25}\\\Rightarrow\ x=\frac{800\times72}{3\times25}\\\Rightarrow\ x=768\text{ hours}[/tex]

Hence, there are 768 hours in 72 days.

To find the value of x when q(x) = -4, we set up the equation and solve for x.

To find the value of x for which the function q(x) is equal to -4, we can set up the equation q(x) = -4 and solve for x.

Given q(x) = 1/2x - 3, we can substitute -4 for q(x) and solve:

-4 = 1/2x - 3

Adding 3 to both sides, we get:

-1 = 1/2x

Multiplying both sides by 2 to isolate x, we have:

-2 = x

Therefore, the value of x that makes the function q(x) equal to -4 is x = -2.

Multivariate statistical techniques are a key tool used by scientists to find patterns in large data sets, allowing them to make predictions and understand relationships between variables.

One example of a tool that scientists use to find patterns in their data is multivariate statistical techniques. These techniques, often referred to as pattern analyses, are excellent at discovering and summarizing consistent patterns in large data sets. By applying these methods, scientists can identify cause and effect relationships, use graphs and charts to represent data visually, and make predictions based on the identified patterns.

Whether in biology, physics, or any other scientific field, finding patterns is essential for understanding relationships between variables, explaining general phenomena, and making meaningful predictions.

The question involves the division of decimal numbers by whole numbers. The results are 2.06, 21.3, 5.41, and approximately 2.96, respectively. For calculations, the decimal point in the quotient is aligned with the decimal point in the dividend.

Division of Decimal Numbers

The given question involves the division of decimal numbers by whole numbers. These operations can be easily performed using long division or a calculator:

To perform these divisions, place a decimal point in the quotient (the result) directly above the decimal point in the dividend (the number being divided). Then, proceed with the division as you would with whole numbers, bringing down the digits past the decimal point as necessary.

No, Clara is not correct.

Here,

Clara says that if you square the number 4 and then divide the result 2, you end up with 4.

We have to find that Clara is correct or not.

What is expressions ?

Expression in math is a phrase that can contain numbers ( 1, 2, 3 etc.), variables ( x, y, z etc.) and operators

Now,

Clara says that if you square the number 4 and then divide the result 2, you end up with 4.

If we square the number 4 we get,

[tex]4^{2} = 16[/tex]

And, then divide by 2,

[tex]\frac{16}{2} = 8[/tex]

Which is not equal to 4.

Hence, Clara is not correct.

To find how many ways you can buy 60 cookies using single cookies or packages of 10 or 30, you solve for non-negative integer solutions to the equation x + 10y + 30z = 60 and count the combinations.

The question concerns the number of ways to purchase a specific quantity of an item when given different packaging options. Here, we want to find out how many ways you can buy 60 cookies when they are sold singly or in packages of 10 or 30.

To solve this, we can set up a mathematical equation where x, y, and z represent the number of single cookies, 10-cookie packages, and 30-cookie packages, respectively. The equation would be:

x + 10y + 30z = 60

We are looking for all non-negative integer solutions to this equation. By examining the possible combinations, we can systematically list out the ways to achieve the total of 60 cookies using these packaging options.

By counting all the combinations, we can determine how many different ways there are to purchase exactly 60 cookies.

The true statement is b. Yes, the figure can be rotated 90°

Does the figure have rotational symmetry

From the question, we have the following parameters that can be used in our computation:

The figure (a square)

Rotational symmetry means that an object looks the same after a certain amount of rotation around a central point.

In the case of a square, it has rotational symmetry of 90 degrees. This means that if you rotate a square by 90 degrees (a quarter turn), it will look exactly the same as it did before the rotation.

Hence, the true statement is b. Yes, the figure can be rotated 90°
