The distance of the moon from the earth is 3,84,014 km. Insert commas suitably and write the distance according to Indian and International Systems of Numeration.

Answers

Answer:

Indian system of numeration:

With the Indian system, when writing a million, a comma comes after the first three digits and then after 2 digits from thenceforth.

For instance, a million would be:

= 10,00,000

Distance to moon in Indian numeration = 3,84,014 km

International System of Numeration:

Here a comma separates a maximum of 3 digits. A million here would be:

= 1,000,000

Distance to moon is therefore:

= 384,014 km

Which is greater

4. Maria also wants to study the relationship between the way of puppies at birth and their adult weight at 2 years old she collected data from five randomly so like a small breeds dogs and display the data on the table.

Part C:perform a linear regression and interpret the results

A. Use a calculator to perform a linear regression. Round The valleys your calculator gives you for A and b to the nearest hundredth.

B. What is the slope of the regression equation? What does this mean in terms of the birth weight and adult weight?

C. What is the value of the correlation coefficient?

Answers

Answer:

Hello! The answers will be in explanation :D

Step-by-step explanation:

a) You can use a linear regression calculator online to get the equation. You would get the equation: y = 4.87x + 2.28

b) The slope would be 4.87, m is the slope in the slope-intercept equation. The slope represents that for each puppy that is at birth, their adult weight adds 4.87 pounds each time.

c) The value of the correlation coefficient is 0.989. Again, you could always search up a correlation coefficient calculator online and get the same solution I have.

Hope this helps! ^^

Answer:

Part C. Perform a linear regression and interpret the results.

a. Use a calculator to perform a linear regression. Round the values your calculator gives you for a and b to the nearest hundredth. (2 points)

y = ___4.87____x + ____2.28___

b. What is the slope of the regression equation? What does this mean in terms of birth weight and adult weight? (2 points)

The slope of the regression equation is 4.87. This means that as the puppies get older they will get heavier at a rate of 7.87

c. What is the value of the correlation coefficient? (1 point)

The Correlation coefficient has a value of 0.989

A trapezoid with base measures of 23 km and 29 km has an area of 390
km2 find the height of the trapezoid.

Answers

I think it’s 15km dodos

Answer:

height (h) = 15

Step-by-step explanation:

To figure this out, we use the formula 2 · [tex]\frac{A}{a + b}[/tex], where "A" is the area, "a" is one base measure, and "b" is the other base measure.

After plugging in the numbers into the formula, we get 2 · [tex]\frac{390}{23 + 29}[/tex], which equals 15.

How do you find the perimeter on s polygon?PLS HELP ME on this question

Answers

You have to find the perimeter on s polygon then you got your answer

Answer:

To find the perimeter of a polygon, you just have to add the values of each side.

For example, if a rectangle has a length of 10 inches and a width of 5 inches, you would add, 10 + 10 + 5 + 5, which is equal to 30. This is found because the length of one side is 10, the other is also 10, and the width is 5, and the other is also 5.

The launch used for captain lighners scenic tours hold 170 litres of fuel. The boat uses 34L each hour. i need an equation for this please help

Answers

Answer:

The information we have is:

The boat can hold 170 L of fuel

The boat uses 34L each hour.

With this information, we can find the total amount of time that the boat can be used.

If the boat is used x hours, then it needs:

x*34L of fuel.

And the maximum amount of fuel that the boat can use uis170 L

Then we can solve:

x*34L = 170L

Now we can divide both sides by 34L to isolate x.

x = 170L/34L = 5

This means that the boat can be used for 5 hours.

Isaac’s dad built a shelf for his video games that is 42 inches wide.Each video game is 6/8 inches wide.How many video games can Isaac fit on the shelf ?

Answers

Answer: 56

Step-by-step explanation:

Since we are informed that Isaac’s dad built a shelf for his video games that is 42 inches wide and that each video game is 6/8 inches wide.

The number of video games that Isaac can fit on the shelf will be gotten by dividing the length of the shelf by the width of each video game. This will be:

= 42 ÷ 6/8

= 42 × 8/6

= 56

Therefore, Isaac can fit 56 video games on the shelf.
