The population of a city, P, in millions, is a function of t, the number of years since 2010, so P=f(t). What does the statement

Crazy boy [7]

Answer:

$f(5) = 10$

The population of city is 10 millions in year 2015 that is 5 years after 2010.

Step-by-step explanation:

We are given the following information in the question:

The population of a city, P, in millions, is a function of t.

$P= f(t)$

where P is the population of city in millions and t is the number of years after 2010.

We have to interpret the meaning o the statement f(5) = 10.

$f(5) = 10$

Interpretation:

Comparing the relation we get,

It means that the population of city is 10 millions in year 2015 that is 5 years after 2010.

4. The following intervals were plausible population proportions for a given sample. Find the margin of error in each case.

Vedmedyk [2.9K]

Answer: a. 0.15 b. 0.03 c. 0.055 d. 0.05

Step-by-step explanation:

For plausible intervals of population proportions , the margin of error is basically half of the difference between upper limit and lower limit.

a. Interval = From 0.35 to 0.65

Upper limit = 0.65

Lower limit = 0.35

Difference = Upper limit- Lower limit

= 0.65-0.35=0.30

Margin of error = (Difference)÷2 =(0.30)÷2=0.15

b. Interval = From 0.72 to 0.78

Upper limit = 0.78

Lower limit = 0.72

Difference = 0.78-0.72 = 0.06

Margin of error =(0.06)÷2=0.03

c. Interval = From 0.84 to 0.95

Upper limit = 0.95

Lower limit = 0.84

Difference =0.95-0.84= 0.11

Margin of error = (0.11)÷2 = 0.055

d.Interval = From 0.47 to 0.57

Upper limit = 0.57

Lower limit = 0.47

Difference = 0.57-0.47=0.10

Margin of error = (0.10)÷2=0.05

The points A, B and C have position vectors OA = 6,2, OB = 3,4 and OC = 12, -2 respectively.

kari74 [83]

Answer:(a) BA = (-3,2) (b) BC = (-9,6)

Step-by-step explanation: (a) Vector BA = position vector of B - position vector of A = vector OB - vector OA = (3-6) i + (4-2) j = -3i+2j [i, j are unit vectors along x and y-axis respectively]. Also vector BA=(-3,2). (b) Vector BC = position vector of B - position vector of C = vector OB - vector OC = (3-12) i + (4-(-2)) j = -9i+6j [i, j are unit vectors along x and y-axis respectively]. Also vector BA=(-9,6).
