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:

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

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

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

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

$Correlation \ coefficient \ (r) \simeq 0.95$

Kimmy bought a 5kg mg can of peanuts for $4.50 what is the unit price

Lina20 [59]

We know that the cost of 5 kg of peanuts is $4.50, then the unit price per kilogram is $4.50/5 kg = 0.90 $/kg And the unit price per gram is: $0.90 / kg * 1 kg/1000 = 0.0009 $/g or 0.09 cents/gram
