set of data shown?

Which Is Most Likely The Correlation Coefficient For Theset Of Data Shown?

Answers

Answer 1

Answer:

0.872

Step-by-step explanation:

The regression fits the data well leavubgbiut just one of the points, this shows there is a strong relationship between the plotted variables. Also, we have to look at the direction of the regression line which will give us an idea of the slope, hence the type of correlation between the two variables (either positive or negative relationship). In this case the slope is positive and hence the correlation Coefficient will be positive as well. Hence we can say there is a strong positive relationship between the variable. The only option which depicts this association is 0.872

How much would you need to deposit into an account that pays 6.5% interest compounded semiannually to have $10,000 after 7 years?

Answers

Answer:

6390.56

Step-by-step explanation:

[tex]AV=PV(1+\frac{i}{n})^{nt}\\10000=x(1+\frac{.065}{2})^{7*2}\\10000=1.564807232*x\\6390.53=x[/tex]

9514 1404 393

Answer:

  $6490.57

Step-by-step explanation:

The future value is given by the compound interest formula ...

  A = P(1 +r/n)^(nt)

Principal P earns annual rate r compounded n times per year for t years.

Filling in the given values, we have ...

  10000 = P(1 +0.065/2)^(2·7) = P(1.0325^14)

  P = 10000/1.0325^14 ≈ 6390.5635

You would need to deposit $6390.57 into the account to have $10,000 in 7 years.

_____

Additional comment

Using the rounded-down result of the computation will result in a value after 7 years of $9,999.99, not quite $10,000. Rounding the computed value up to $6390.57 ensures the account balance will actually be $10,000.00 after 7 years.

If the balance is rounded to the nearest penny each time interest is added, then the balance after 7 years will be exactly $10,000.00. If there is no intermediate rounding, the resulting balance will be $10,000.01.

Most of the time, the answer key doesn't pay attention to details like this. Your expected answer may be $6390.56, or $6391 if rounded to dollars.

Find the area of the circle use 3.14 for pie d=6ft

Answers

Answer:

28.26 ft.²

Step-by-step explanation:

Mathematics: Explain/formula.

To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.

[tex]\pi r^2(3.14*radius*radius)[/tex]

[tex]\pi =pi[/tex]

Mathematics: Solve.

Here, the diameter is 6 ft.

To find the radius, divide the diameter by 2.

[tex]6/2=3[/tex]

[tex]radius=3[/tex]

Now, we can plug the numbers into the formula.

[tex]\pi 3^2(3.14*3*3)=28.26[/tex]

Mathematics: Conclude.

Therefore, the area of this circle is 28.26 ft.²

the area of the given circle will be 28.27 ft².

What is Area?

The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

Given, a circle that has a diameter of 6 ft,

Since, Radius = diameter/2

Thus,

Radius = 6/ 2

Radius = 3ft

From the formula of the area of the circle:

Area = pi* radius *radius

In our case,

Area = pi * 3 * 3

Area = 28.274

Therefore, the area of the given circle will be 28.27 ft².

Write 11 k-6 (2k+5)in expanded form and find the sum

Answers

Answer:

Option B

Step-by-step explanation:

Expression representing the series is,

[tex]\sum_{k=6}^{11}(2k+5)[/tex]

Here, k = Number of terms

By placing k = 6, 7, 8, 9, 10, 11 in the expression we can get the terms of the series.

For k = 6,

(2k + 5) = 2(6) + 5

            = 17

For k = 7,

(2k + 5) = 2(7) + 5

             = 19

For k = 8,

(2k + 5) = 2(8) + 5

            = 21

For k = 9,

(2k + 5) = 2(9) + 5

            = 23

For k = 10,

0(2k + 5) = 2(10) + 5

            = 25

For k = 11,

(2k + 5) = 2(11) + 5

            = 27

Therefore, expanded form will be,

17, 19, 21, 23, 25, 27

There, is a common difference in each successive to previous term,

d = 19 - 17

d = 2

Number of terms 'n' = 6

First term = 17

Sum of an arithmetic sequence is given by,

[tex]S=\frac{n}{2}[2a+(n-1)d][/tex]

Therefore, sum of the given sequence will be,

   = 3(34 + 10)

S = 132

A population of emperor penguins has a mean weight of 77 pounds with a standard deviation of 16 pounds. What would be the standard deviation of sample means taken from this population with a sample size of 50?

Answers

Answer:

2.263

Step-by-step explanation:

standard deviation of sample means = s/\sqrt{n}

Given

Standard deviation s = 16pounds

Sample size n = 50

Substituting

standard deviation of sample means = 16/\sqrt{50}

standard deviation of sample means = 16/7.071

standard deviation of sample means = 2.263

Hence the standard deviation of sample means taken from this population with a sample size of 50 is 2.263

Step-by-step explanation:

__________

Answer:

x = 130°

y = 50°

z = 130°

Step-by-step explanation:

From the diagram, you can see that the angle given, 50° is a vertical angle to y. This means they are equal, so y = 50°.

Next, angle x, and the given 50° angle are supplementary since they form a straight line. Because of this, you get that:

50° + x = 180°

- and -

x = 130°

You can see that angle z is a vertical angle to angle x, so they are equal, which gives you z = x = 130°. --> z = 130°
