2.  213.5

3.  46

4.  225

5.  530

The correlation coefficient measures the relationship between the two variables

The correlation coefficient is 0.234

The formula of correlation coefficient is:

[tex]r = \frac{1}{n - 1} * \sum{(\frac{x - \bar x}{\sigma_x})*(\frac{y - \bar y}{\sigma_y})[/tex]

Using the dataset from the complete question, we have:

[tex]r = \frac{1}{5 - 1} * 0.9375[/tex]

Evaluate the difference

[tex]r = \frac{1}{4} * 0.9375[/tex]

Evaluate the quotient

[tex]r = 0.234375[/tex]

Approximate

[tex]r = 0.234[/tex]

Hence, the correlation coefficient is 0.234

Answer:

There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance.

Step-by-step explanation:

When our p-value exceeds level of significance then we fail to reject our null hypothesis. In this scenario we are investigating if there exists significant difference in the birth weights of a mother's first child and second child and our null hypothesis is there exists no significant difference in the birth weights of a mother's first child and second child i.e.μd=0.

As we are given that p-value is greater than 10% level of significant so, we cannot reject our null hypothesis. Thus, the conclusion statement can be written as "There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance."

PLEASE RATE!!

Hello.

Please remember that equivalent means equal.

So we need to find 4 fractions that are equal to

[tex]\displaystyle\frac{4}{7}[/tex]

There are infinitely many fractions equal to the given fraction; we need just 4 of them.

First, let's multiply the numerator (4) and the denominator (7) times 2:

[tex]\displaystyle\frac{8}{14}[/tex]

Now, let's multiply the numerator and denominator of this fraction by 2:

[tex]\displaystyle\frac{16}{28}[/tex]

Multiply by 2 once more:

[tex]\displaystyle\frac{32}{56}[/tex]

I hope it helps.

Have an outstanding day. :)

Answer:

D.) QS ≅ NR

Step-by-step explanation:

Congruency between QS and NR can be assumed because the angles they make at points T and U are both right angles and the 6.7 seems to be indicating the same length of the lines (?)

Nonetheless, they look to be about equal in size and angle, so D.) QS ≅ NR is your best answer.

Answer:

  (-√(6-√26) < x < √(6-√26)) ∪ (x < -√(6 +√26)) ∪ (√(6 +√26) < x)

Step-by-step explanation:

Using x^2 = z, the equation can be rewritten as ...

  z^2 -12z +10 > 0

  (z -6)^2 -26 > 0

  |z -6| > √26

This resolves to two equations.

This one ...

  x^2 -6 < -√26 . . . . substitute x^2 for z

  |x| < √(6-√26) . . . . add 6, take the square root; use √a^2 = |a|

  -√(6-√26) < x < √(6-√26)

__

and this one ...

  x^2 -6 > √26

  |x| > √(6 +√26)

  x < -√(6 +√26) ∪ √(6 +√26) < x

Answer:

x = -15

Step-by-step explanation:

5 (x - 7) = 7x - 5

Remove the parentheses

5x - 35 = 7x - 5

Move the terms

5x - 7x = -5 + 35

Collect like terms Calculate

-2x = 30

Divide both sides

x = -15

Answer:

mTW = 230

Step-by-step explanation:

Remark

You have to assume that O is the center of the circle. Two sectors are marked as equal, so equate them to find x

Equation and Solution

5x + 5 = 4x - 20               Subtract 5 from both sides

5x + 5 - 5 = 4x+ 20 - 5    Combine

5x = 4x + 15                     Subtract 4x from both sides.

5x-4x = 4x-4x + 15

x = 15

TOU = 5*15 + 5 = 80

VOW = 80                         TOU and VOW  are marked as equal

UOV = 6x -20 =  70

Total of all three = 80 + 80 + 70 = 230

Answer:

Step-by-step explanation:

In each case, put the function argument where the variable is and do the arithmetic (or algebra).

a) f(-9) = 3(-9)^2 -2(-9) = 3·81 +18 = 261

__

b) g(-3) = -8(-3)-(-3) = 24 +3 = 27

__

c) f(p+4) = 3(p+4)^2 -2(p+4)

  = 3(p^2 +8p +16) -2p -8

  = 3p^2 +22p +40

_____

Additional comment

The form of g(x) is unusual, leading us to suspect it might be ...

   g(x) = -8x^2 -x

In that case,

  g(-3) = -8(-3)^2 -(-3) = -8·9 +3 = -69

Answer:

25 tickets more

Step-by-step explanation:

I got x+y is (less than or equal to) 55 for the first inequality and 60x+40y>600 for the second one!

Step-by-step explanation:

Since Blaine can sell a maximum of 55 tickets, the first inequalitly is x+y is less than OR EQUAL TO 55. Since the tickets in the back section cost $40 each, 40y represents the money made from those tickets. Blaine needs to make 600 in sale so the inequality is 60x+40y>600.

The number of days Christen's book is overdue could be 22 according to options given.

The graph which represents the relationship between the number of days a book is overdue and the library fine charged is attached below :

According to the graph, a constant relationship exists between the number of days a book is overdue and the library fine charged when the Number of days book is  overdue is about 19 days and above such that the library fine charged stays the same at $10.

Since we are told that Christen's fine for returning the book is the same as the fine she would have paid if book was returned yesterday, then, the number of days Christen's book is overdue could be 20 days and above.

The only value above 20 from the options given is 22.

Hence, 22 is the valid answer.

If we look at the both the triangles then the

From above, we can conclude that :-

Both the triangles are similar by AA Similarity

Hence, Option A is correct.

[tex]\bold{\huge{\underline{ Solution \:2}}}[/tex]

Let consider the given triangle be ABC and the line that divides the triangle consider it as DE

So,

We have to find the value of x

In ΔABC, By using BPT theorem

That is,

[tex]\sf{\dfrac{ AD }{ AB }}{\sf{ = }}{\sf{\dfrac{DE}{BC}}}[/tex]

Subsitute the required values,

[tex]\sf{\dfrac{ 6 }{ 6 + 4 }}{\sf{ = }}{\sf{\dfrac{8}{x}}}[/tex]

[tex]\sf{\dfrac{ 6 }{ 10 }}{\sf{ = }}{\sf{\dfrac{8}{x}}}[/tex]

[tex]\sf{\dfrac{ 3 }{ 5 }}{\sf{ = }}{\sf{\dfrac{8}{x}}}[/tex]

[tex]{\sf{ x = 8{\times} }}{\sf{\dfrac{5}{3}}}[/tex]

[tex]{\sf{ x = }}{\sf{\dfrac{40}{3}}}[/tex]

[tex]{\sf{ x = 13}}{\sf{\dfrac{1}{3}}}[/tex]

Hence, Option C is correct

[tex]\bold{\huge{\underline{ Solution \:3}}}[/tex]

Here,

For x,

By using BPT theorem,

[tex]\sf{\dfrac{ AB }{ RS }}{\sf{ = }}{\sf{\dfrac{BC}{ST}}}[/tex]

Subsitute the required values,

[tex]\sf{\dfrac{ 2 }{ 4 }}{\sf{ = }}{\sf{\dfrac{x}{6}}}[/tex]

[tex]\sf{\dfrac{ 1 }{ 2 }}{\sf{ = }}{\sf{\dfrac{x}{6}}}[/tex]

[tex]\sf{ x = }{\sf{\dfrac{6}{2}}}[/tex]

[tex]\sf{ x = 3 }[/tex]

Thus, The value of x is 3

For y

Again by using BPT theorem,

[tex]\sf{\dfrac{ AB }{ RS }}{\sf{ = }}{\sf{\dfrac{AC}{RT}}}[/tex]

Subsitute the required values,

[tex]\sf{\dfrac{ 2 }{ 4 }}{\sf{ = }}{\sf{\dfrac{5}{y}}}[/tex]

[tex]\sf{\dfrac{ 1 }{ 2 }}{\sf{ = }}{\sf{\dfrac{5}{y}}}[/tex]

[tex]\sf{ y = 5{\times}2 }[/tex]

[tex]\sf{ y = 10 }[/tex]

Thus, The value of y is 10

Hence, Option A is correct.

Answer:

6:30 P.M.

Step-by-step explanation:

Since Kachina must do all these things before 7:30 P.M., we must find the sum of the times of the things she must do before the concert and subtract it from 7:30

The sum of the minutes is 60, which is 1 hour.  Thus, Kachina should leave 1 hour before 7:30 which is 6:30 P.M.
