I have $1000 invested in a coin worth $43000. If the coin reaches $100000 how much will I have invested?
Pavel [41]

Answer:

$2326

Step-by-step explanation:

I have $1000 invested in a coin worth $43000. If the coin reaches $100000 how much will I have invested?

To solve the above question, we have:

$43,000 = $1000

$100,000 = x

Cross Multiply

43000 × x = 100,000 × 1000

x = 100000 × 1000/43000

x = $2325.5813953

Approximately = $2326

Therefore, If the coin reaches $100000 you would have invested $2326

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
