The Pretty Pizza Company wants to open a new pizza place either on the north side of town or the south side of town. They want t

o open the pizza place where the ratio of pizza places per person is currently less than 0.01. The population of 15 blocks of the north side of town is 221 people per block, but there are already 32 pizza places in the area. The population of 22 blocks of the south area is 150 people per block, and there are 28 pizza places in the area. Where, if anywhere, should the Pretty Pizza Company open a new pizza place?

Target: ratio of pizza places / person < 0.01

<span>The population of 15 blocks of the north side of town is 221 people per block, but there are already 32 pizza places in the area.

population = 15*221 =  3,315

ratio: 32 pizza places / 3315 people = 0.0097 pizza places per person

Which indeed is less than 0.01 => this area is good for their purpose.

The population of 22 blocks of the south area is 150 people per block, and there are 28 pizza places in the area.</span>

population: 22*150 = 3300

ratio: 28 pizza places / 3300 people = 0.00085 which is also less than 0.01

Both places meet the target of less than 0.01 places per person, but the south area seems better than north area.

The numbers of regular season wins for 10 football teams in a given season are given below. Determine the range, mean, variance,
galina1969 [7]

Answer:

Range = 13

Mean = 8.3

Variance = 17.61

Step-by-step explanation:

Given the population dataset :

2, 9, 15, 4, 12, 9, 13, 6, 3, 10

1.) Range : (maximum - minimum)

Maximum = 15 ; minimum = 2

Range = (15 - 2) = 13

2.) population mean (μ) :

μ = ΣX / n

n = sample size

μ = (2 + 9 + 15 + 4 + 12 + 9 + 13 + 6 + 3 + 10) / 10

μ = 83 / 10

μ = 8.3

3.) Population variance (s²)

Σ(x - μ)² / n

=[(2 - 8.3)^2 + (9 - 8.3)^2 + (15 - 8.3)^2 + (4 - 8.3)^2 + (12 - 8.3)^2 + (9 - 8.3)^2 + (13 - 8.3)^2 + (6 - 8.3)^2 + (3 - 8.3)^2 + (10 - 8.3)^2] / 10

s² = 176.1 / 10

s² = 17.61

Find two postive numbers such that the ratio of the two numbers is 5 to 3 and the product of the two numbers is 540.
svet-max [94.6K]

Answer:

337.5 and also 202.5

Step-by-step explanation:

do 8x = 540 since 5 and 3 are in a ratio... so you get 5x plus 3x. Then you solve for x and get 67.5..67.5 times 3 is 202.5 and 67.5 times 5 is 337.5.

For question 22, divide each number by 1.41 to see which one produces a quotient larger than 0.9. d is the answer.
For #23, multiple 0.155 million by 86%, the result is 133,300
again, d is the correct answer.
