Fran would like to estimate the mean amount of time it takes people in her town to travel to work. the town's population is 150,

000 and about 90,000 of those are working adults. which statements are true?
a larger sample of working adults will provide a better estimate of the true mean than a smaller sample

the population of working adults is too large for using a sample to estimate the mean of the entire group

if she takes a random sample of the population of working adults in her town, the mean for that group is likely close to the mean for the entire group

there is no way to infer the value of the mean. she must collect data for all 90,000 working adults and calculate the mean​

Because it is like having a unit of measurement that is set

V=(7π4^2)/3

V=112π/3 ft^3

V≈117.29 ft^3  (to nearest hundredth of a cubic foot)

A realtor is decorating some homes for sale, putting a certain number of decorative pillows on each twin bed and a certain numbe
VikaD [51]

The number of decorative pillows did the realtor arrange on each twin bed and queen bed is 6 and 9 respectively.

<h3>Simultaneous equation</h3>

let

  • Number of decorative pillows for twin bed = x
  • Number of decorative pillows for queen bed = y

x + y = 15

2x + y = 21

From equation (1)

x = 15 - y

  • Substitute x = 15 - y into (2)

2x + y = 21

2(15 - y) + y = 21

30 - 2y + y = 21

- 2y + y = 21 - 30

-y = -9

y = 9

Substitute y = 9 into

x + y = 15

x + 9 = 15

x = 15 - 9

x = 6
