What is the figure formed?What is the area of the figure?

\large \green{ \underline{ \blue{ \boxed{\bf{ \red{Solution-}}}}}}

The given points lie on graph as per the order given in the attachment.

Which shape?

As the points lie 2 units apart from their adjacent sides. It can be a square or rhombus.

The opposite pairs of sides are also parallel to each other. The adjacent sides of the figure formed are also perpendicular to each other.

<u>Hence! the figure formed is a square.</u>

What is the area?

\large{\sf{ \longmapsto Area_{(square)} = s \times s}}

\large{\sf{ \longmapsto Area_{(square)} = {s}^{2} }}

\large{\sf{ \longmapsto Area_{(square)} = {(2)}^{2} }}

\large{\sf{ \longmapsto Area_{(square)} = 4 \: sq. \: units}}

The manager of a grocery store reports that there is a 12 percent chance that a customer buys apples during a shopping trip, a 5
Ivanshal [37]

Answer:

The probability of a customer buying carrots is 0.10.

Step-by-step explanation:

Here, given:

P (Customer buying apples) = 12%  

⇒   P(A) = 12 \100 = 0.12

P(Customer Buying apples AND Carrots) = 5%  

   ⇒   P(A ∩ C ) = 5 /100 = 0.05

P(Customer buying apples OR carrots ) = 17%    

⇒   P(A∪ C) = 17/100 =   0.17

Now, we know that:

<h3> P(X ∪ Y) = P(X) + P(Y) -  P(X ∩ Y ) </h3><h3></h3>

Now, here substituting the values, we get:

P(A∪ C)  = P(A) + P(C) - P(A ∩ C )

⇒  0. 17  =  0.12 + P(C) -  0.05

or, 0.17 - 0.07 = P(C)

or, P(C) = 0.10

or, P(Customer Buying Carrots) = 0.10

Hence, the probability of a customer buying carrots is 0.10.

A student cost for last semester at her community college was $3000. She spent $540 of that on books. What percent of last semes
eduard
Hi there!
We can set up a ratio to model the problem...
540/3000 = x/100
Now, just cross multiply and solve for x.
54000 = 3000x
x = 18
Therefore, 18 percent of last semester's college costs was spent on books. Hope this helped and have a great day!
