When dividing by a ratio add the ratio together
so
4+5+9=18
then
180/18=10
10*4=40
10*5=50
10*9=90
so your answer is
40:50:90

If you would like to divide 180 in the ratio of 4 : 5 : 9, you can do this using the following two steps:

First, add the numbers: 4 + 5 + 9 = 18
Second, divide and multiply: 4 / 18 * 180 = 40
                                             5 / 18 * 180 = 50
                                             9 / 18 * 180 = 90

The result you are looking for is 40 : 50 : 90.

Which scatterplot has a correlation coefficient closest to r = 1?
qwelly [4]

Answer:

The scatter diagram that contains the correlation coefficient closest to r = 1 is the first one shown in the attached images.

Step-by-step explanation:

The correlation coefficient "r" measures how much two variables x and y are related. When the variables are highly related, the value of r is closer to one and the points contained in the scatter diagrams are assimilated more and more to a line. When the value of r is positive the relation is crescent and therefore the slope of the line drawn by the points in the diagram has a positive slope


Therefore, to answer this question, one must search among the attached images for the dispersion diagram in which the points resemble a straight line with a positive slope.


The scatter diagram that meets the requirements mentioned is the first one that appears in the attached images

V^2+2=8-4v^2 solve the question algebically
iris [78.8K]

Answer:

v =  ± sqrt(6/5)

Step-by-step explanation:

v^2+2=8-4v^2

Add 4v^2 to each side

v^2+ 4v^2+2=8-4v^2+ 4v^2

5v^2 +2 = 8

Subtract 2 from each side

5v^2  +2-2 = 8-2

5 v^2 = 6

Divide each side by 5

5v^2 /5 = 6/5

v^2 = 6/5

Take the square root of each side

sqrt(v^2)  = ± sqrt(6/5)

v =  ± sqrt(6/5)

sergejj [24]

Solution :

a). The point estimate of proportion of college graduates among women who work at home,

$\hat p =\frac{166}{506}$

  = 0.3281

99.5% confidence interval

$=\left( \hat p \pm Z_{0.005/2} \sqrt{\frac{\hat p (1- \hat p)}{n}} \right)$

$=\left( 0.3281 \pm 2.81 \sqrt{\frac{0.3281 \times  (1- 0.3281)}{506}} \right)$

$=(0.3281 \pm 0.0586)$

$=(0.2695, 0.3867)$

Find the value of x in the picture please
Marianna [84]

Answer:

Option B. The value of x is 20

Step-by-step explanation:

we know that

<u>The intersecting chords theorem</u>  states that the products of the lengths of the line segments on each chord are equal.

so

In this problem

(x)(x-11)=(x-8)(x-5)\\x^{2}-11x=x^{2}-5x-8x+40\\-11x=-13x+40\\2x=40\\x=20
