Step-by-step explanation:

I have no answer to choose...

$\dfrac{12}{27}=\dfrac{12:3}{27:3}=\dfrac{4}{9}\\\\\dfrac{12}{27}=\dfrac{12\cdot2}{27\cdot2}=\dfrac{24}{54}\\\\\dfrac{12}{27}=\dfrac{4}{9}=\dfrac{4\cdot2}{9\cdot2}=\dfrac{8}{18}\\\vdots$

You can multiply (divide) the numerator and the denominator by the same number different from 0 then the value of the fraction will not change

(you will get a fraction equal to given)

in Marlas school 6/15 of the students do not ride the bus to school. of these students 5/9 walk to school. what fraction of the

Debora [2.8K]

Answer:

The fraction of the students that walk in in Marla's school is equal to $\frac{2}{9}$

Step-by-step explanation:

Let

x------> the total students in Marla's school

we know that

The number of students that not ride the bus is equal to

$\frac{6}{15}x\ students$

The number of students that walk to the school is equal to

$\frac{6}{15}x*\frac{5}{9}=\frac{2}{9}x\ students$

therefore

The fraction of the students that walk in in Marla's school is equal to $\frac{2}{9}$

I can't figure this one out....Find ALL polar coordinates of point P = (6, 31°). The explanations I've found thus far don't seem

arsen [322]

Check the picture below.

so, as I see it, we can simply move from the point P, 360° counter-clockwise, the green one, and we'll be landing on a positive angle on the 1st Quadrant, the angle of 360° + 30° = 390°.

we can also move 360° clockwise, the red one, from P, so we'll be landing at -360° + 30 = -330°, also on the 1st Quadrant, but a negative counterpart.

now, if we move by jumps of 360° on either direction, we'll be landing coterminal with P all the time, so if we use simply multiply 360° by "n", some integer, then that angle added or subtracted from 30°, will be coterminal with P.

( 6 , 30°±360n°) where n ∈ ℤ.

Use the data tab of the graphing tool to display the data from Luther’s table in a scatter plot, with x representing the number

gogolik [260]

The equation of the line of best fit is y = -4.75X + 88.6 and the absolute value of the correlation coefficient is 0.906

<h3>The equation of the line of best fit</h3>

The data values of the question are as follows:

(1, 88), (2, 75), (3, 71), (4, 69), (5,66), (6, 68), (7, 50)

To determine the equation of the line of best fit, we make use of a graphing calculator.

From the graphing calculator, we have the following summary:

Sum of X = 28
Sum of Y = 487
Mean X = 4
Mean Y = 69.5714
Sum of squares (SSX) = 28
Sum of products (SP) = -133
The value of R is: -0.906.

The line of best fit equation is

y = bx + a

Where

b = SP/SSX = -133/28 = -4.75

a = MY - bMX = 69.57 - (-4.75*4) = 88.57143

So, we have:

y = -4.75X + 88.57143

Approximate

y = -4.75X + 88.6

Hence, the equation of the line of best fit is y = -4.75X + 88.6

<h3>The absolute value of the correlation coefficient</h3>

In (a), we have:

The value of R is: -0.906.

This represents the correlation coefficient.

The absolute value is

|R| = 0.906.

Hence, the absolute value of the correlation coefficient is 0.906
