You burn 265 calories running and then 7 calories per minute swimming.

Your friend burns 273 calories running and then 11 calories per minute swimming.

Let us assume that both of you swim for x minutes.

Calories burnt by you = 265+7x

Calories burnt by your friend = 273+11x

Difference between both = 273+11x-(265+7x)

= 273+11x-265-7x

= 8+4x

Use a Venn diagram to answer.<br> If n(A) = 8, n(B) = 9 and n(An B) = 6, what is n(AUB)?

marin [14]

Answer:

$n(A \cup B) = 6$

Step-by-step explanation:

In Venn sets, we have that:

$n(A \cup B) = n(A) + n(B) - n(A \cap B)$

In which n is the number of elements that each set contains.

In this question:

$n(A) = 8, n(B) = 9, n(A \cap B) = 6$

$n(A \cup B) = n(A) + n(B) - n(A \cap B) = 8 + 9 - 6 = 17 - 6 = 11$

$n(A \cup B) = 6$
