Answer:

29.33π cm³  or 92.10 cm³

Step-by-step explanation:

To find the volume of a cone with height 5.5 and radius 4, we will simply use the formula;

volume of a cone = \frac{1}{3} π r² h

h = 5.5  and r= 4, we will simply plug in these values into our formula

volume of a cone  =  \frac{1}{3}   ×  π   × (4)² (5.5)

                               = \frac{1}{3}  ×π × 16 × 5.5

                                =88π   /  3

                                 =29.33π

volume of cone = 29.33π

But π= 3.14

plugging in π=3.14, we have;

volume of cone = 29.33(3.14)=29.10

Answer:

For question 2 (Triangle):

The triangle hThe entire triangle area = 2 * 13.125 =

26.25

 

Triangle perimeter both legs = 16.6 + base (7) = 23.6

For question 1 (Parallelogram):

longer congruent sides = 6-0 OR 4-(-2) = 6units

area= 3×6 = 18units^2

Answer: A, B, D

A, B, and D are equations because an equation has an equal sign that connects two expressions together (i.e., equations have equal signs). In this case, only A, B, and D have equal signs.

Each of three bags A, B, C contains white balls and black balls. A has a1 white & b1 black, B has a2 white & b2 black an
Alex73 [517]

Answer:

See explanation ( Answers are too long)

Step-by-step explanation:

We will first compute a general probability for picking a white ball:

          P (W) = a_1 / (a_1 + b_1) + a_2 / (a_2 + b_2) + a_3 / (a_3 + b_3)

part a)

We are asked to find the probability of white ball given that it pulled from bag A. So if we express it in notation we are asked for P ( A / W). We will use conditional probability to answer our question:

                           P ( A / W ) = P ( W & A ) / P (W)

                           P ( W & A ) = a_1 / (a_1 + b_1)

Hence,

P ( A / W ) = [a_1 / (a_1 + b_1)] / [a_1 / (a_1 + b_1) + a_2 / (a_2 + b_2) + a_3 / (a_3 + b_3)]    

part b)

We are asked to find the probability of white ball given that it pulled from bag B. So if we express it in notation we are asked for P ( B / W). We will use conditional probability to answer our question:

                           P ( B / W ) = P ( W & B ) / P (W)

                           P ( W & B ) = a_2 / (a_2 + b_2)

Hence,

P ( A / W ) = [a_2 / (a_2 + b_2)] / [a_1 / (a_1 + b_1) + a_2 / (a_2 + b_2) + a_3 / (a_3 + b_3)]    

part c)

We are asked to find the probability of white ball given that it pulled from bag C. So if we express it in notation we are asked for P ( C / W). We will use conditional probability to answer our question:

                           P ( C / W ) = P ( W & C ) / P (W)

                           P ( W & C ) = a_3 / (a_3 + b_3)

Hence,

P ( A / W ) = [a_3 / (a_3 + b_3)] / [a_1 / (a_1 + b_1) + a_2 / (a_2 + b_2) + a_3 / (a_3 + b_3)]
