Answer:

a set of four data pairs with a correlation coefficient r = –0.8

Explanation:

The correlation coefficient, or r value, tells us how well the regression model fits the data.  The r values range from -1 to 1, with -1 being a perfect fit of a negative trend and 1 being a perfect fit of a positive trend.  The closer the r value is to -1 or 1, the better the line fits; the closer the r value is to 0, the worse the fit.

Since the r value is -0.8, which is very close to 1 (think 80%), this means this would be a good candidate for linear regression.

List 2 integers that are congruent to 4 modulo 14.
vivado [14]

Answer:

32, 46

Step-by-step explanation:

Remember, a is congruent to b modulo d if d divides a-b.

Now, the problem says that b=4 and d=14.

Let a=32. Observe that a-b=28 and \frac{28}{14}=2, then 32 is congruent to 4 modulo 14.

Let a=46. Observe that a-b=46-4=42 and \frac{42}{14}=3, then 46 is congruent to 4 modulo 14.

dot is taller than dab but shorter than dee, and dave is taller than don prove: E is the last letter of the name of the tallest
LUCKY_DIMON [66]

Step-by-step explanation:

It starts off by saying Dot is taller than Dab.

Then it says he is shorter the dee.

Then it states that another name dave is taller then don.

We dont necessarily know if dee or dave is the tallest but both of there last names end with E so it proves the question at hand.

Please help ASAP! Will give brainiest! And please answer! What is the area of the triangle in the coordinate plane?
Vinvika [58]
First we need to find the base and height of the triangle. We can see that the base goes from 3 to 11 on the coordinate plane. If we take 11 - 3, we get 8.
8 is our base. We can also see that the height goes from 3 to 12. 12 - 3 is 9, so our height is 9.
The formula for a triangle is (1/2)bh so 8 x 9 is 72, and 72 times 1/2 is 36.
The area of the triangle on the coordinate plane is 36 units

‌

So , the HCF of 4 and 9 is 1
