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

-9x^2 + 12x + 5
Step-by-step explanation:
I'm assuming you meant (3x – 2)^2. The " ^ " indicates exponentiation and is required. We then have:
9 - (3x – 2)^2, which, when expanded, is
9 - (9x^2 -12x + 4), or:

Answer:
3.27
Step-by-step explanation:
Let us assume that the values are the side of a right triangle where;
Hypotenuse = 6 (longest)
Angle of elevation = 33 degrees
Required
x = opposite side
Using the trig identity
Sin theta = opp/hyp
Sin 33 = x/6
x = 6sin33
x = 6(0.5446)
x = 3.27
Hence the value of x is 3.27
Note that the values of the sides are assumed.

Answer:
(13/2)^27
Step-by-step explanation:
First note that ( )^0 = 1, so we need not bother with the last term.
Next, note that
(2/13)^(-6) divided by (2/13)^3 is (2/13)^(-9).
Finally, we must cube this last result. We get: (2/13)^(-9*3) = (2/13^(-27)
or
(13/2)^27

Multiply the values on the outside of the parenthesis by what is on the inside.
5x + 15 = -2x + 12
Combine like terms by bringing them over to the other side using the necessary operation (addition or subtraction).
Bring -2x over to the left side by adding it to 5x.
5x + 2x = 7x
Bring 15 over to the right side by subtracting it from 12.
12 - 15 = -3
Now we have:
7x = -3
We need to get the x all by itself, so we divide both sides by 7.
7x/7 = x
-3/7 cannot be simplified further, so it is left as -3/7.

How can you write 200.000 using a whole number and a power
Answers
Answer:
2 x 10^5
200,000 / 10 = 20,000
20,000 / 10 = 2,000
2,000 / 10 = 200
200 / 10 = 20
20 / 10 = 2
I divided 200,000 by 10 five times to get a number less than 10.
So, 5 is going to be the exponent.
Question Explanation:
In other words you can write 200,00 using a whole number and a power 10 using scientific notation!
In scientific notation you want a number less than 10 multiplied by 10 to the power of a number.
Solution:
200,000 / 10 = 20,000
20,000 / 10 = 2,000
2,000 / 10 = 200
200 / 10 = 20
20 / 10 = 2
I divided 200,000 by 10 five times to get a number less than 10.
So, 5 is going to be the exponent.

Which of the following is a factor of
X^2
- 2x + 15
Select one
X-5
X+3
None of the above
X-3
Answers
Answer:
both (x - 5) and (x - 3) are factors of x^2 - 2x + 15
Step-by-step explanation:
Please write this all on one line: x^2 - 2x + 15.
Recognize that 3*5 = 15. Possible factors of x^2 - 2x + 15 are thus (x - 5) and (x + 3). Multiplying these together results in x^2 - 2x + 15, so we have verified that both (x - 5) and (x - 3) are factors of x^2 - 2x + 15.
f(x) = x² - 2x + 15
Solution:This function f(x) will have the negative "discriminant" in root ; thus forming complex roots
So this function has no rational roots
