.In the given venn - diagram , A and B are the
sets of students who like apple and banana
respectively. if n(U)=48 and n(AUB)=36, find:​

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

the answer is a.

step-by-step explanation:

in three games of golf, alex shot two under par four times.

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
