Answer:

D. Polar.

Step-by-step explanation:

We are asked to choose the two most commonly used systems of coordinates.

We know that most commonly used systems of coordinates are the rectangular coordinate system and the polar coordinate system.

The rectangular coordinate system is also known as Cartesian coordinate system.

Therefore, option D is the correct choice.

Answer:

I'll setup the problem and leave the computation to you

Step-by-step explanation:

The equation to calculate fixed payments

$P = \frac{r(PV)}{1- {(1 + r)}^{ - n} }$

P= payments

r = interest rate for the period (which is a quarter )

PV = present value (or the amount borrowed)

n = number of periods

r = .25/4 (4 months = quarter of a year)

n = 4*10

PV = R450550.00

Suppose you want to estimate the proportion of cars that are sport utility vehicles (SUVs) being driven in Kansas City, Missouri

ahrayia [7]

Answer:

The sample size 'n' = 721

Number of cars 'n' = 721

Step-by-step explanation:

Explanation:-

Given Population proportion 'p' = 0.40

Given Margin of error = 0.03

90% of level of significance

$Z_{\frac{\alpha }{2} } = 1.645$

The Margin of error is determined by

$M.E = \frac{Z_{\frac{\alpha }{2} S.D} }{\sqrt{n} }$

$0.03 = \frac{1.645 X \sqrt{0.40(1-0.40) } }{\sqrt{n} }$

on calculation , we get

0.03√n = 0.8058

$\sqrt{n} = \frac{0.8058}{0.03} = 26.86$

squaring on both sides , we get

n = 721.45≅721

conclusion:-

The sample size 'n' = 721

Number of cars 'n' = 721

Linear equation of plant height is h = (1/2)w + 3

Given:

Height of experimental plant = 3cm

Average growth = 0.5 cm per week

Find:

Linear equation of plant height

Computation:

Given;

h = Plant height

w = number of weeks

So,

Plant height = Height of experimental plant + (Average growth)(number of weeks)

h = 3 + (0.5)(w)

h = (1/2)w + 3

Option "J" is the correct answer to the following question.
