A prop for the theater club’s play is constructed as a cone topped with a half-sphere. What is the volume of the prop? Round you

marta [7]

Volume of cone formula: V = PI x r^2 x h/3

Volume of sphere formula: 4/3 x PI x r^3

Cone: 3.14 x 9^2 x 9/3 = 763.02 cubic inches

1/2 sphere: 1/2 x 4/3 x 3.14 x 9^3 = 1526.04 cubic inches.

Total volume : 1526.04 + 763.02 = 2289.1 cubic inches

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:

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

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

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

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

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

Use the distributive property and then combine like terms to simplify this expression: 9x + 5(x + 4)

Ilia_Sergeevich [38]

Answer:

14x+20

Step-by-step explanation:

9x + 5(x + 4)

Apply the Distributive Property:

$9x+5(x+4)=9x+5x+20$

$9x+5x+20$

Combine Like Terms:

The like terms are 9x and 5x.

$9+5=14$

$9x+5x+20=14x+20$

The simplified equation is: $14x+20$
