The correlation coefficient for the data in the table was found to be 0.93.

The correct option is A.

<h3>What is the correlation coefficient?</h3>

The correlation coefficient focuses on the linear relationship between two variables.

Given

The first column is labeled time spent at the dentist (in hours) with entries 1.4, 2.7, 0.75, 1.6.

The second column is labeled bill amount (in dollars) with entries 235, 867, 156, 215.

The numbers between -1 and 1 should be one of the values related to the bill.

Taking the independent variable or input variable as, the time a patient spends at the dentist and the dependent variable or output variable as the amount of the bill.

Hence, The correlation coefficient for the data in the table was found to be 0.93.

Segment AB is on the line y − 4 = −5(x − 1), and segment CD is on the line y − 4 = one fifth(x − 5). Which statement proves the
Genrish500 [490]

Answer:

Segments AB and CD are perpendicular to each other.

Step-by-step explanation:

If you were to convert line segments AB and CD into slope-intercept form(y=mx+b), you would get y=-5x+1 for AB and y=1/5x-5.

Any line with a slope that is flipped-oppisite (-5/1 to -1/5 to1/5)

of another line must be perpendicular to each other. It doesn't have to have the same y-intercept, it just makes the intersecting point different.

Write the standard form of the equation of the circle with the given characteristics. Center: (3, 5); Solution point: (−2, 17)
Angelina_Jolie [31]

\text{we know that the general equation of the circle is }\\&#10;\\&#10;(x-h)^2+(y-k)^2=r^2\\&#10;\\&#10;\text{where, (h,k) is the center of the circle and r is the radius.}\\&#10;\\&#10;\text{Given that the centered of the circle is at  }(h,k)=(3,5)\\&#10;\text{and a solution point on circle is (-2,17).}\\&#10;\\&#10;\text{so the radius of the circle will be the distance between center and the }

\text{solution point. so using the distance formula, we have}\\&#10;\\&#10;\text{Radius, }r=\sqrt{(-2-3)^2+(17-5)^2}\\&#10;\\&#10;\Rightarrow r=\sqrt{25+144}\\&#10;\\&#10;\Rightarrow r=\sqrt{169}\\&#10;\\&#10;\Rightarrow r=13\\&#10;\\&#10;\text{Hence using the standard for of circle, equation of circle with center}\\&#10;(h,k)=(3,5) \text{ and radius r=13 is}\\&#10;\\&#10;(x-3)^2+(y-5)^2=(13)^2\\&#10;\\&#10;\Rightarrow (x-3)^2+(y-5)^2=169

the ratio of horses to chickens on a farm is 9:4. If there are a total of 169 animals, how many chickens are on the farm?
Evgesh-ka [11]

Answer:

<h2> 52 chickens</h2>

Step-by-step explanation:

Step one:'

given

we are told that the total number of animals is 169

the ratio of horses to chickens= 9:4

total ratio= 13

Required:

number of chickens

Applying part to all principle, let the number of chickens be x

4/13=x/169

cross multiply

4*169=13*x

divide both sides by 13

x=4*169/13

x=676/13

x=52

There are 52 chickens
