I need the tsa of a triangular prism

The answer is 840ft2

Step-by-step explanation:

for the two rectangles, use the formula: length x width

15 x 13 = 195

Since you have two rectangles on each sides, multiply by 2

45 x 2 = 390ft2

for the triangle, use the formula: base x height

                                                                    2

18 x 12

    2

=  108

since you have 2 triangles (one at the front, one at the back), multiply by 2

108 x  = 216ft2

For the rectangle on the bottom

18 x 13 = 234ft2

Add for the TSA

234 + 390 + 216 = 840ft2

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
