the correlation coefficient for Alfonso survey is 0.36.

The correlation coefficient is a quantitative method of calculating correlation. It is a statistical concept, which helps in establishing a relation between predicted and actual values obtained in a statistical experiment.

For the given situation,

The table below shows the values of the data x, y and the correlation calculations.

The formula of correlation coefficient is

[tex]r=\frac{n(\Σ xy)-(\Σ x)(\Σ y)}{\sqrt{[n\Σ x^{2} -(\Σ x)^{2} }] [n\Σ y^{2}-(\Σ y)^{2} ]}[/tex]

From the table substitute all the values.

⇒ [tex]r=\frac{(11)(98-(37)(26))}{\sqrt{[11(153)-37^{2} ][(11)(92)-26^{2} ] }}[/tex]

⇒ [tex]r=\frac{1078-962}{\sqrt{(1683-1369)(1012-676)} }[/tex]

⇒ [tex]r=\frac{116}{\sqrt{(314)(336)} }[/tex]

⇒ [tex]r=\frac{116}{324.81}[/tex]

⇒ [tex]r=0.357[/tex] ≈ [tex]0.36[/tex]

Hence we can conclude that the correlation coefficient for Alfonso survey is 0.36.

Answer:

1, Because the half-life is 6 hours, the initial amount is halved every 6 hours. Due to the total of 18 hours, the starting amount will be divided by 2 (halved) three times. You will then have one-sixth of the original amount, which is 384 grams divided by six equals 48 grams.

N = 39

Step-by-step explanation:

N + 13 = 52

-13. -13

N = 39

Answer:

n = 39

Step-by-step explanation:

To find what n equals, I want to get it alone on one side of the equation.

To do this, I move 13 to the right side of the equation by subtracting 13 from both sides.

13-13=0 so n is the only value on the left side

52-13=39.

You are now left with n = 39

To check that this is right, add 13 to 39. It equals 52, so you know the answer you found is correct.

Answer:

T = 0.29p

Step-by-step explanation:

From the table Given :

We can obtain the uint cost per pound of wood :

Cost of 12 pounds of wood = $3.48

Cost per pound = Cost / weight

Cost per pound = $3.48 / 12 = $0.29

Hence, the proportional relationship cost, T in dollars and p pounds of wood is ;

Cost = unit cost per pound * number of pounds

T = 0.29 * p

T = 0.29p

Answer:

70

Step-by-step explanation:

The equation are x = y + 50  and 5x + 2y = 950

Firstly, let x represent the number of adult tickets sold and let y represent the number of student tickets sold.

Since there was 50 more adult tickets sold compared to student tickets, hence this statement can be represented by the equation:

x = y + 50 (1)

Also, they collected a total of $950. Each adult ticket was $5 while female ticket was $2, hence:

5x + 2y = 950     (2)

5(y + 50) + 2y = 950

y = 100

x = 100 + 50

x = 150

Solving equations 1 and 2 simultaneously gives y = 100 and x = 150

Therefore they was 150 adult tickets and 100 student tickets

Answer:

Percent increase is 21%

Step-by-step explanation:

Initial cost of shoes = $72

New price of shoes = $87

Increase in price of shoes = New price of shoes - Initial cost of shoes

= [tex]87-72[/tex]

= $15

Percentage increase in price of shoes = ( Increase in price of shoes ÷ Initial cost of shoes) × 100

= [tex]\frac{15}{72}(100)=20.8\%[/tex]

≈ 21%

So, percent increase is 21%

hope this helps

Step-by-step explanation:

The statement is false because the area could be changed if the dimensions are changed.

Supposing that there is no direct formula available for deriving the area,

we can derive the area of that region by dividing it into smaller pieces, whose area can be known directly.

Then summing all those pieces' area gives us the area of the main big region.

The statement is given that 'Changes in the dimensions of the shape do not affect the area of the shape'.

The statement is false because the area could be changed if the dimensions are changed.
