Find the coefficient of correlation between and X and Y if covariance between X and Y is 15 and the variance of X and Y are resp
IRINA_888 [86]

Answer:

0.95

Step-by-step explanation:

Correlation \ coefficient \   (r) = \dfrac{covaraince \  between \ X \ and \ Y }{SD_X \times SD_Y }

Correlation \ coefficient \   (r) = \dfrac{15 }{10^{1/2} \times 25^{1/2} }

Correlation \ coefficient \   (r) = \dfrac{15 }{3.162 \times 5 }

Correlation \ coefficient \   (r) = \dfrac{15 }{15.81 }

Correlation \ coefficient \   (r) \simeq 0.95

Can someone please help me
svp [43]

Answer:

m < 2 = 137°

m < 4 = 137°

Step-by-step explanation:

Given that m < 7 = 43°, we can say that it has the same measure as < 3 because they are corresponding angles. Thus, we can establish that m < 3 = 43°.

We can use m < 3 = 43° to find m < 4, as they are supplementary angles that have a sum of 180°.

Therefore:

m < 3 + m < 4 = 180°

Rearrange the formula to isolate m < 4:

m < 4 = 180° - m < 3

Substitute the value of m < 3 into the rearranged formula:

m < 4 = 180° - m < 3

m < 4 = 180° - 43°

m < 4 = 137°

Therefore, m < 4 = 137°.

< 2 and < 4 also have the same measure because they are vertical angles.  Two angles are vertical angles if they are opposite angles formed by the intersection of two lines.  

Hence, m < 2 = 137°

Given: x - 5 &gt; -10. Choose the solution set. {x | x R, x &gt; -5} {x | x R, x &gt; 15} {x | x R, x &lt; 5} {x | x R, x &lt; -
kvv77 [185]

Answer:

{x | x R, x > -5}

Step-by-step explanation:

Given:

x-5>-10

Add 5 both sides, we get

x-5+5>-10+5\\x>-5

Therefore, the solution is x>-5 where, x is a real number.

So, {x | x R, x > -5} is the correct answer.
