Answer:

a. Chi-square test of independence

Step-by-step explanation:

The chi square statistics is also used to test the hypothesis about the independence of two variables each of which is classified into a number of categories or attributes.

In the given problem the Equal , more or less are the attributes.

The goodness of fit test is applicable when the cell probabilities depend upon the unknown parameters provided that the unknown parameters are replaced with their estimates and provided that one degree of freedom is deducted for each parameter estimated.

You have a home with a market value of $144,700, which has an assessment value of 72% of that amount. your city has a property t

CaHeK987 [17]

Your taxes went to funding schools will be $2641.The tax is divided into different parts based on the percentage.

A government-mandated contribution to state revenue is placed on employees' wages and corporate earnings or added to the cost of certain products, services, and transactions.

The given data in the problem is;

The market value of the home = is $144,700

They assessed a value of 72% of that amount.

The city has a property tax rate of 0.039.

The assessment value is found as;

$\$ \ 144,700 \times 0.72 = \$ \ 104,184$

The tax on the property will be;

$\$ \ 104,184 \times 0.039 = \$ \ 4,063.176$

The amount which goes to funding schools is;

$\$ \ 4,063.176 \times 0.65= \$ \ 2641.0644$

Hence your taxes went to funding schools will be $2641.

A circle's radius that has an initial radius of 0 cm is increasing at a constant rate of 7 cm per second. Write a formula to exp

Alex Ar [27]

Answer:

r = 7t

or not mathematically,

r(t) = 7t

r(t) means, r, which is a function of t.

Step-by-step explanation:

Initial size of the radius = 0 cm, at t = 0 s

Rate of increase of the radius of the circle = 7 cm/s

dr/dt = 7

dr = 7 dt

∫ dr = 7 ∫ dt

r = 7t + C (C is the constant of integration)

At t = 0, r = 0,

0 = 0 + C

C = 0

r = 7t.

r(t) = 7t

Factor and solve the problems in the photo ……….. pleaseeeee help i haven’t done algebra in 2 years

vladimir1956 [14]

Answer:

30. 2x²-x-1=0

or, 2x²-2x+x-1=0

or, 2x(x-1)+1(x-1)=0

or, (x-1)(2x+1)=0

so, x-1 = 0 or, x = 1

and 2x+1 = 0 or, 2x = -1 or, x = -1/2

so, x = 1 and 1/2

31. 3x²-14x=5

or, 3x²-14x-5=0

or, 3x²-15x+x-5=0

or, 3x(x-5)+1(x-5)=0

or, (x-5)(3x+1)=0

so, x-5=0 or, x=5

and 3x+1=0 or, 3x=-1 or, x=-1/3

so, x = 5 and -1/3

Use the given qualitative data to construct the relative frequency distribution.

ikadub [295]

Answer:

Category Relative Frequency

male survivors 17.3%

males who died 63.7 %

Female survivors 15.1 %

Females who died 3.8%

Step-by-step explanation:

The relative frequency is the proportion of the number of times the event occurs to the total number of trials.

Given : Total people on ship = 2274

Number of male survivors = 394

⇒ Relative Frequency of male survivors = $\dfrac{394}{2274}$

In percent , $\dfrac{394}{2274}\times100\approx17.3\%$

Number of males who died =1449

⇒ Relative Frequency of male who died = $\dfrac{1449}{2274}$

In percent , $\dfrac{1449}{2274}\times100\approx63.7\%$

Number of female survivors =344

⇒ Relative Frequency of female survivors = $\dfrac{344}{2274}$

In percent , $\dfrac{344}{2274}\times100\approx15.1\%$

Number of females who died = 87

⇒ Relative Frequency of females who died = $\dfrac{87}{2274}$

In percent , $\dfrac{87}{2274}\times100\approx3.8\%$

Hence, the complete table would be :

Category Relative Frequency

male survivors 17.3%

males who died 63.7 %

Female survivors 15.1 %

Females who died 3.8%
