\frac{3}{4n}-18^{(4n}=\frac{1}{4n}-4^{(4n}\\\\ 3-72n=1-16n\\\\ -72n+16n=1-3\\\\ -56n=-2 \\\\ \boxed{n=\frac{-2}{-56}=\frac{1}{28}}

1) Multiply both sides by 4: 3n - 72 = n - 16
2) Subtract n from both sides: 2n - 72 = -16
3) Add 72 to both sides:  2n = 56
n = 28.

Twenty-five bakery customers were surveyed to determine if they like cake or pie. The results are shown in the Venn diagram. Cir
nikitadnepr [17]

Answer:

Probability = 2/7

Step-by-step explanation:

AS the Venn diagram is not given in the question, the question is incomplete. I've attached the Venn diagram of this question below for a better understanding of the question and its solution.

In the Venn diagram we can see that

Costumers who like Cake = 10

Costumers who like Pie = 8

Costumers who like both = 4

So it means that

Total costumers who like Cake = 10 + 4 = 14

Total costumers who like Pie = 8 + 4 = 12

We have to find probabilty that a costumer who likes cakes also likes pie

So

Total costumers who like cake = 14

Costumers out of 14 who also like pie = 4

Probability = (No. of costumers who also like pie) / (Total costumers who like cake)

Probability = 4/14 = 2/7

Finding angle measures using triangles
S_A_V [24]
Because HI and JK are parallel, that makes their angles congruent. So angle K equals angle I
So the interior angles of a triangle add up to 180°
So, Angle I + angle H + angle x =180°
60°+56°+x°=180°
116°+x°=180°
X=180-116
X=64°
