2,640/k=11 what is the value of k

Answer:

Step-by-step explanation:

The null hypothesis

[tex]H_o:p=0.64[/tex]

The alternative hypothesis

[tex]H_1:p \neq 0.64[/tex]

At 0.02 level of significance,

the testing firm rejects the null hypothesis.

This implies that the rejection of the null hypothesis shows that there is sufficient evidence to reject a newsletter publisher who believes that 64% of their readers own a Rolls Royce.

Answer:

[tex]y=-x+7[/tex]

Step-by-step explanation:

Equation of straight line is given as

[tex]y-y_1=m(x-x_1)[/tex]

where slope m is calculated as

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here

[tex](x_1, y_1)=(1, 6) \ \ and \ \ (x_21, y_2) = (5, 2)[/tex]

[tex]m = \frac{2 - 6}{5 - 1}\\m=\frac{- 4}{4} \\m=-1[/tex]

Equation of line that passes through the points (1,6) and (5,2)

[tex]y-6=-1(x-1)\\y=-x+7[/tex]

Answer:

[tex]D = \frac{25\sqrt{13}}{13}[/tex]

Step-by-step explanation:

Given

[tex]y = 4 - \frac{2}{3}x[/tex]

[tex](x_1,y_1) = (-2,-3)[/tex]

Required

Determine the distance

[tex]y = 4 - \frac{2}{3}x[/tex]

Write the above equation in standard form:

[tex]Ax + By + C = 0[/tex]

So, we have:

[tex]\frac{2}{3}x+y - 4 = 0[/tex]

By comparison:

[tex]A = \frac{2}{3}[/tex]  [tex]B = 1[/tex] and [tex]C = -4[/tex]

The distance is calculated using:

[tex]D = \frac{|Ax_1 + By_1 + C|}{\sqrt{A^2 + B^2}}[/tex]

Where:

[tex](x_1,y_1) = (-2,-3)[/tex]

[tex]A = \frac{2}{3}[/tex]  [tex]B = 1[/tex] and [tex]C = -4[/tex]

This gives:

[tex]D = \frac{|\frac{2}{3} * (-2) + 1 * (-3) - 4|}{\sqrt{(\frac{2}{3})^2 + 1^2}}[/tex]

[tex]D = \frac{|-\frac{4}{3} -3 - 4|}{\sqrt{\frac{4}{9} + 1}}[/tex]

Take LCM

[tex]D = \frac{|\frac{-4-9-12}{3}|}{\sqrt{\frac{4+9}{9}}}[/tex]

[tex]D = \frac{|\frac{-25}{3}|}{\sqrt{\frac{13}{9}}}[/tex]

[tex]D = |\frac{-25}{3}|/\sqrt{\frac{13}{9}}[/tex]

[tex]D = \frac{25}{3}/\sqrt{\frac{13}{9}}[/tex]

Split the square root

[tex]D = \frac{25}{3}/\frac{\sqrt{13}}{\sqrt{9}}[/tex]

Change / to *

[tex]D = \frac{25}{3}*\frac{\sqrt{9}}{\sqrt{13}}[/tex]

[tex]D = \frac{25}{3}*\frac{3}{\sqrt{13}}[/tex]

[tex]D = \frac{25}{\sqrt{13}}[/tex]

Rationalize

[tex]D = \frac{25}{\sqrt{13}} * \frac{\sqrt{13}}{\sqrt{13}}[/tex]

[tex]D = \frac{25\sqrt{13}}{13}[/tex]

Hence, the distance is:

[tex]D = \frac{25\sqrt{13}}{13}[/tex]

Answer:

4/18

Step-by-step explanation:

It would be a 4/18 chance she would get another blue marble, because first you add all of the marbles together which is 5+6= 11 + 7 = 18, so there are 5 blue marbles, and we have a chance of pulling another blue one 5/18 but since we already took one out, there are only 4 blue marbles left, so it's a 4/18.

Answer:

x = 10 yd

Explanation:

These triangles are based on proportions. 12 yd is proportional to 18 yd, and x yd to 15 yd. We want to find x. We'll use the rule of three to calculate the unknown number.

12/18 = x/15

x = (12 · 15)/18

x = 10 yd (10 yards from the hut to the gold coins)

Mark is 18 years old.

Answer: 15

Step-by-step explanation:

Answer:

A → C = 150h + 250 ( where C is charge )

B → C = 175h + 150

for 26 hours

A → C = (150 × 26 ) + 250 = 3900 + 250 = $4150

B → C = (175 × 26 ) + 150 = 4550 + 150 = $4700

Attorney A is cheaper for 26 hours, thus better deal

Equate the 2 equations to find hours they charge the same

175h + 150 = 150h + 250 ( subtract 150h from both sides )

25h + 150 = 250 ( subtract 150 from both sides )

25h = 100 ( divide both sides by 25 )

h = 4 ← number of hours when charges for both are equal

Attorney A becomes a better deal at 5 hours

Answer: Option A x>38

Step-by-step explanation:

I took the test and got 100% on it.

The solution is : x = 77 and x > 38.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

we know that,

Sum of all angles in a triangle is 180.

The angle PNO will hence be:

180 - 38 - 39 = 103 degrees.

The angle PNO + angle x = 180 degrees (straight line)

So 103 + x = 180,

therefore x = 180 - 103 = 77.

Which is also greater than 38,

so x > 38 is also correct.
