When calculating startup costs, it's essential to consider both the market and the product you want to produce. In our infographic analysis, the startup cost of a lemonade stand in today's world would range from under $10 to almost $400 for a pre-fab stand ordered from the Internet and a fancy Breville juice extractor.

Each of the 12 cards shown has a number and a color or pattern. Each card is equally likely to be drawn. Find each probability.

Sever21 [200]

Answer:

A) P(stars) = 1/3

B) P(odd)= 4/7

C)P(solid grays or stars or striped)= 1

D)P(1,4 or 7)= 3/7

E)P(not striped)= 2/3

Step-by-step explanation:

Given:

sample set contains 1-7 solid gray, 1-7 stars and 1-7 striped cards

Let solid gray be x

stars be y

striped be z

then sample set be

1x,2x,3x,4x,5x,6x,7x,

1y,2y,3y,4y,5y,6y,7y,

1z,2z,3z,4z,5z,6z,7z

total number of cards in sample set =21

Now

a)Finding probability of stars

Number of star cards in above sample set = 7

P(stars)= 7/21

P(y)=1/3

b)Finding probability of odd

Number of odd cards in above sample set = 12

P(odd)= 12/21

=4/7

c)Finding probability of solid grays or stars or striped

P(solid grays or stars or striped) = P(x or y or z)

=P(x U y U z)

As the events are mutually exclusive

P(x U y U z)= P(x)+P(y)+P(z)

now P(x)= 1/3

P(y)=1/3

P(z)=1/3

P(x U y U z) = 1/3 + 1/3 + 1/3

= 3/3

d)Finding probability of 1,4 or 7

Number of 1,4 or 7 cards in above sample set = 9

P(1,4 or 7) = P(1 U 4 U 7)

As the events are mutually exclusive

P(1,4 or 7) = P(1) + P(4) + P(7)

P(1)= 3/21

=1/7

P(4)= 3/21

=1/7

P(7)= 3/21

=1/7

P(1,4 or 7)= 1/7 + 1/7 + 1/7

=3/7

e)Finding probability of not striped

Number of not striped cards in above sample set = 14

P(not striped)= 14/21

= 2/3 !

The radius of a circle is 4 inches. What is the circle's circumference?

mojhsa [17]

Answer:

8π inches or approximately 25.12 inches

Step-by-step explanation:

What's the circumference of a circle?

❖ The circumference of a circle is the distance around a circle.

How do we find the circumference of a circle?

❖ The formula to find the circumference of a circle is 2πr, where r =

radius. We can solve in terms of pi, or approximate pi to 3.14

Solving

$\pi * 4*2$
$\pi *8$
8π inches

or

$3.14*4*2$
$3.14*8$
25.12 inches
