Answer:

Step-by-step explanation:

Example:

Consider A vertex. A is connected with two other vertices C and B.

Thus 3 line segments are formed. At A, two pair of intersecting lines are formed, AC & AE ; AE and AB

Each vertex form two pair of intersecting line segments. Totally , there are 8 verteces. So, 8*2 = 16 pair of intersecting lines

Samantha wants to use her savings of 1150 to buy shirts and watches for her family. The total price of the shirt she bought was

ioda

Answer-

The maximum number of watches that Samantha come by with her savings is 10.

Solution-

The amount of money Samantha has in her savings account = $1150

She wants to buy shirts and watches.

Cost of one shirt = $84

Cost of each watch = $99

Let she can buy maximum of x watches, so the net price of the watches is $99x.

Then,

$\Rightarrow 99x+84=1150\\\\\Rightarrow 99x=1150-84\\\\\Rightarrow 99x=1066\\\\\Rightarrow x=\dfrac{1066}{99}\\\\\Rightarrow x=10.77$

As the number of watches can not be in fraction, so at most she can buy 10 watches.

There are 30 blue balls, 40 red balls, and 30 white balls in a bag of balls. What is the conditional probability of choosing a b

natulia [17]

Answer: So, the probability will be

$P( \text{getting a blue ball })=\frac{30}{70}=\frac{3}{7}$

Step-by-step explanation:

Since we have given that

Number of blue balls =30

Number of red balls = 40

Number of white balls = 30

Since there are 100 balls in total ,

As we have given that there is no white ball chosen.

So, only 70 balls are left with us , from which we choose a blue ball

So, the probability will be

$P( \text{getting a blue ball })=\frac{30}{70}=\frac{3}{7}$
