A correlation coefficient between average temperature and coat sales is most likely to be __________.

Lostsunrise [7]

A correlation coefficient between average temperature and coat sales exists most likely to be between 0 and -1.

<h3>What is the correlation coefficient?</h3>

The correlation coefficient exists as the exact measure that quantifies the power of the linear relationship between two variables in a correlation analysis. A correlation coefficient between average temperature and coat sales exists most likely to be between 0 and -1.

A negative correlation suggests two variables that tend to move in opposite directions. A correlation coefficient of -0.8 or lower displays a strong negative relationship, while a coefficient of -0.3 or lower signifies a very weak one.

The sum of the reciprocals of two consecutive even integers is 3/4 Find the two integers.

Vedmedyk [2.9K]

$\Large{ \underline{ \underline{ \bf{ \orange{Solution:}}}}}$

Let one of those even numbers be x, Then other even number would be x + 2.

According to question,

⇛ Their reciprocal add upto 3/4

So, we can write it as,

⇛ 1/x + 1/x + 2 = 3/4

⇛ x + 2 + x / x(x + 2) = 3/4

⇛ 2x + 2 / x² + 2x = 3/4

Cross multiplying,

⇛ 3(x² + 2x) = 4(2x + 2)

⇛ 3x² + 6x = 8x + 8

⇛ 3x² - 2x - 8 = 0

⇛ 3x² - 6x + 4x - 8 = 0

⇛ 3x(x - 2) + 4(x - 2) = 0

⇛ (3x + 4)(x - 2) = 0

Then, x = -4/3 or 2

☃️ It can't be -4/3 because it is fraction and negative number. So, x = 2

Then, x + 2 = 4

✤ So, The even numbers are 2 and 4.

PLEASE DON'T GUESS!! x-2/x^2+3x-10

Juliette [100K]

Hey kirinaallison, thanks for submitting your question to Brainly!

The answer is $\frac{1}{x+5}$

$x^{2}$ +5x - 2x - 10
x(x+5) - 2 (x+5) - 2(x+5)
(x + 5) (x-2)

Hope my answer was well explained if you have any more questions reply to my answer. :)
