Calculate the area of this triangle.

99 cm²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = 18 and h = 11, thus

A = × 18 × 11 = 9 × 11 = 99 cm²

the answer would be c:   ax + b = ax + c

step-by-step explanation:

85.560%

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
