P(at least two have same birthday) =
1 - (1/2)^(n).

Since no specific number of students is given, we only get an expression.

yan [13]

Answer:

0.16

Step-by-step explanation:

Length = 5 units
Number of broken sticks= 3
Equal lengths = 5 units/3

See the picture attached for reference.

As you see the best points are the green areas which covers 2 out of 5 zones.

Since it is same for both broken points, the probability of this is:

2/5*2/5 = 4/ 25 = 0.16

Answer is 0.16

the equation y=15x can be used to determine the amount of money y pauli's pizzeria makes by selling x pizzas . the graph shows t

abruzzese [7]

Answer:

Pauli's pizzeria make more money per pizza

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find out the slope of the graph of Leo's pizzeria

looking at the graph take the point (2,24)

The graph show a proportional relationship (the line passes through the origin)

The slope is m=y/x

we have

For x=2, y=24

substitute

m=24/2=$12 per pizza sold

The linear equation is

y=12x

step 2

Compare the slopes

Pauli's pizzeria

we have

y=15x -----> slope m=$15 per pizza sold

Leo's pizzeria

we have

y=12x -----> slope m=$12 per pizza sold

$15 per pizza sold > $12 per pizza sold

therefore

Pauli's pizzeria make more money per pizza

What percent of 25 is 7? And What number is 21% of 300?

Hunter-Best [27]

This is for the first one 85.714286%

This is for the second one

olution for 21 is what percent of 300

100%/x%=300/21

(100/x)*x=(300/21)*x - we multiply both sides of the equation by x

100=14.2857142857*x - we divide both sides of the equation by (14.2857142857) to get x

100/14.2857142857=x

7=x

x=7

now we have:

21 is 7% of 300
