Answer:

You will save $2 if you buy from Picture Perfect Pizza instead of Pizza Outpost.

Step-by-step explanation:

First we need to find the unit rate of each pizza from each pizza place.

Picture Perfect Pizza: $3÷2 = $1.50

Pizza Outpost: $7÷4 = $1.75

Picture Perfect Pizza: $1.5 * 8 = $12

Pizza Outpost: $1.75*8 = $14

In the U.S. More male babies are born than females. In 1998 some 2,265,031 males were born and 2,287,419 females were born. Find

suter [353]

Answer: The empirical probability that the individual being born is a male = 0.498

Step-by-step explanation:

Given the following :

Number of males born =2,265,031

Number of females born = 2,287,419

Empirical probability is given as :

P( A) =( Number of possible outcomes of event A ÷ Total number of events)

Total number of events = (number of males born + number of females born)

Total number of events = (2,265,031 + 2,287,419) = 4552450

Probability(individual being born is a boy) =

(Number of males born ÷ Total number of children born)

=2265031÷(2265031+2287419) = 0.49754110424057

Therefore, the empirical probability that the individual being born is a male = 0.498

The perimeter of a swimmingpool is 78 feet. The difference between four times the length and the width is 73.5 feet. What are th

Marianna [84]

Answer:

Length is 22.5 ft

Width is 16.5 ft

Step-by-step explanation:

4L-w=73.5

4L=73.5+w

L=(73.5+w)/4

P=78

P=2L+2w

78=2[(73.5+w)/4]+2w

78=(73.5+w)/2+2w

78=(73.5+w+4w)/2

2•78=73.5+5w

156=73.5+5w

156-73.5=5w

82.5=5w

82.5/5=w

16.5=w

L=(73.5+w)/4

=(73.5+16.5)/4

=90/4

L=22.5
