On Friday, 27 soccer fans are going to a soccer game. A ticket to the game costs $18 per person. Lunch for all 27 fans costs $17

kirza4 [7]

Answer: $x=18(27)+172$

Step-by-step explanation:

You have the following information given in the problem:

- The number of soccer fans that are going to a soccer game is 27.

- A ticket to the game costs $18 per person.

- The cost of the lunch for all 27 fans is $172.

- $x$ represents the total cost of attending the game for all 27 fans.

Therefore, keeping the above on mind you can write the following expression that closely estimates the total cost of attending the game for all 27 fans:

$x=18(27)+172$

The Venn diagram shows the results of two events resulting from rolling a number cube.

gulaghasi [49]

Answer: $P(A\cap B)=\frac{1}{3}$

$P(A)=\frac{1}{3}$

$P(B)=1$

$P(A|B)=\frac{1}{3}$

Step-by-step explanation:

From the given figure it can be seen that

Total number on cube= n(S)=6

Intersection of A and B = n(A ∩ B)= 2

Therefore,

$P(A\cap B)=\frac{n(A\cap B)}{n(s)}=\frac{2}{6}=\frac{1}{3}$

Also, The number of elements in A = 2

Therefore,

$P(A)=\frac{n(A)}{n(s)}=\frac{2}{6}=\frac{1}{3}$

Similarly, The number of elements in B= 6

Therefore,

$P(B)=\frac{n(B)}{n(s)}=\frac{6}{6}=1$

The formula to find the conditional probability is given by :-

$P(A|B)=\frac{P(A\cap B)}{P(B)}\\\\\Rightarrow P(A|B)=\frac{\frac{1}{3}}{1}=\frac{1}{3}$

Amar wants to make lemonade for a birthday party. He wants to mix 12 tablespoons of sugar in water. He only has a teaspoon which

o-na [289]

Answer:48

Step-by-step explanation:

Given

Amar wants 12 tablespoons of sugar in water.

Amar has teaspoon whose four times is equivalent to 1 tablespoon

i.e. $4\ \text{teaspoon}\equiv 1\ \text{tablespoon}$

therefore

$12 tablespoon is 4\times 12$

$\Rightarrow 4\times 12$

$\Rightarrow 48\ \text{teaspoons}$

So, amar need to add $48\ \text{teaspoons}$ for lemonade

If h (x) = {(-2,3), (0,4), (1,6), (2, 9)}<br><br> then what set of values represent h-1 (x) ?

vfiekz [6]

Answer:

$h^{-1}(x)=\{(3,-2),(4,0),(6,1),(9,2)\}$

Step-by-step explanation:

Given: $h(x)=\{(-2,3),(0,4),(1,6),(2,9)\}$

To find: $h^{-1}(x)$

Solution:

A relation is said to be a function if each and every element of the domain has a unique image in the co-domain.

Inverse of a function exist if it is both one to one and onto.

$h(x)=\{(-2,3),(0,4),(1,6),(2,9)\}$

$h^{-1}(x)=\{(3,-2),(4,0),(6,1),(9,2)\}$
