Just multiply:
5 cm*(4 cm)*(1.5 cm) = 30 cm^3
The formula of the volume is area of the base by the height.
Multiply 5.8 by 100 to convert to percent:
<span>5.8 × 100 = </span>580 %
X takes values: { 3, 4, 5 }
where: P ( X = 3 ) + P ( X = 4 ) + P ( X = 5 ) = 1
For X = 3 we have : BBB or GGG.
P ( X = 3 ) = ( 1/2 * 1/2 * 1/2 ) * 2 = 1/8 * 2 = 2 / 8 = 1/4
P ( X = 4 ) = ( 1/2 * 1/2 * 1/2 * 1/2 ) * 6 = 6 /16 = 3/8
P ( X = 5 ) = ( 1/2 * 1/2 * 1/2 * 1/2 * 1/2 ) * 12 = 12 / 32 = 3/8
1 / 4 + 3 / 8 + 3 / 8 = 8 / 8 = 1
Answer: A
Explanation:
(Y-Y1)=m(X-X1) is the base formula for point slope. The points to plug in (X1, Y1) are in this case (2,1). Plugging in those points gives you the equation of Y+1=m(X-2). Then it asks for the slope. In this equation, m = the slope. So plug in (-5) for the slope and you get Y+1=-5(X-2).
Hope this helps!
