You want to draft a four player tennis team. There are eight players to choose from. How many different teams can you form?

Butoxors [25]

We want to make a 4 players team, and there are total 8 players. As we know the order of selection does not matter in a team of players, only the combination of players matters.

So we would use concept of Combinations and It will be choose 4 out of 8 players.

The formula for Combination is given as follows :-

$nCr = \frac{n!}{r!*(n-r)!} \\\\
Choose \;4 \;out \;of \;8 \;players \\\\
8C4 = \frac{8!}{4!*(8-4)!} = \frac{8!}{4!*4!} \\\\
8C4 = \frac{8*7*6*5*4*3*2*1}{(4*3*2*1)*(4*3*2*1)} = \frac{8*7*6*5}{4*3*2*1} =\frac{1,680}{24} = 70 \;combinations$

Hence, Total number of different teams = 70 combinations.

Find the center and radius of the following circle. Then graph the circle.(×+4)2+y2=7

ArbitrLikvidat [17]

Given:

Equation of a circle

$(x+4)^2+y^2=7$

Required:

Find the center and radius of the circle. Then graph of circle.

Explanation:

We have a standard equation of circle

$(x-h)^2+(y-k)^2=r^2$

Whose radius is (h, k) and radius r.

We have equation of a circle

$(x+4)^2+y^2=7$

Now, we will compare with standard equation of a circle

$We\text{ will get center\lparen-4, 0\rparen and radius }\sqrt{7}.$

Graph of circle is

Answer:

Hence, this is the answer.

Chris Shopper received a $1,000 discount loan to purchase a washer and dryer. The loan was offered at 12% for 120 days. What are

Anni [7]

The loan proceeds will be given as follows:
A=P(1+r/100)^n
Plugging the values we obtain
n=4 months=
A=1000(1+12/3*100)^1
A=$1040
hence the proceeds will be:
1040-1000=$40

According to Reuters, a survey undertaken by the National Center for Health Statistics revealed that about 25% of U.S. household

ddd [48]

Answer:

a) P=0.8

b) P=0.67

c) P=0.05

d) P=0.33

e) P=0.45

Step-by-step explanation:

a. What is the probability that the household has only a cell phone and has high-speed Internet?

This probability is stated in the question: "Suppose of U.S. households having only a cell phone, 80% have high-speed Internet", so the probability is P=0.8.

$P(C\&I)=0.8$

b. What is the probability that the household has only a cell phone or has high-speed Internet?

This probability is equal to the sum of the probability of having only a cell phone and the probability of having high-speed internet, less the probability of having both (to avoid counting this household twice).

$P(C\,orI\,)=P(C)+P(I)-P(C)*P(I|C)=0.25+0.65-(0.25*0.8)=0.25+0.62-0.20=0.67$

c. What is the probability that the household has only a cell phone and does not have high-speed Internet?

This is equal to the probability of not having high-speed internet given that it has a cell phone (complementaty of the proability of Point (a)) multiplied by the probability of having a cell phone.

$P(C\&\bar I)=P(\bar I|C)*P(C)=(1-P(\I|C))*P(C)=(1-0.8)*0.25 = 0.2*0.25 = 0.05$
