hello your question has some missing information attached below is the missing information

answer : mean ratio of estimate = 117.62

              standard error ( SE ) = 3.9765

Step-by-step explanation:

Given data : n = 20,  μx = 10.3  , N = 1132

∑ age ( yi) = ( 125 + 119 + --------- + 99 ) =  2148

∑ ( Y - rX)^2 = 6116.728

mean of age ( y ) = ∑ y / 20 =  2148 / 20 = 107.4

mean of diameter ( x ) = ∑x /20 = 188.1 / 20 = 9.405

∴ ratio estimate  = y /x = 107.4 / 9.41 = 11.4195

i) The mean of ratio estimate

= 11.4195 * μx  = 11.4195 * 10.3 = 117.6204

ii) determine the standard error ( SE )

calculate ; [tex]s^{2} _{r}[/tex] = 1 / ( n-1 ) *  ∑ (Y - rX)^2  = 1/19 ( 6116.728 ) = 321.933

Var (  μr ) = [ ( N - n ) / N*n ]*[tex]s^{2} _{r}[/tex]  =  [ ( 1132 - 20 ) / (1132*20) ] * 321.933

               = 15.81226

therefore the SE = √15.81226 ≈ 3.9765

The equation of the line shown in the graph in point-slope form passing through the points (4, 1) and (0, 2) is,

⇒ [tex]y - 1 = \frac{-1}{4} (x - 4)[/tex]

Given that,

Graph of the equation of the line shown in the image.

Use the formula,

The equation of a line in point-slope form passing through the points

[tex](x_1 , y_1)[/tex] and [tex](x_2 , y_2)[/tex] with slope m is defined as;

⇒ [tex]y - y_1 = m (x - x_1)[/tex]

Where, [tex]m = \frac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]

Let us take two points on the graph, which are (4, 1) and (0, 2).

Here, [tex](x_1 , y_1) = (4, 1)[/tex]

And,  [tex](x_2 , y_2)= (0, 2)[/tex]

So, the slope of the line is,

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

[tex]m = \frac{(2 - 1)}{(0-4)}[/tex]

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

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

Therefore, the equation of the line with slope [tex]m = \frac{-1}{4}[/tex] is,

⇒ [tex]y - y_1 = m (x - x_1)[/tex]

⇒ [tex]y - 1 = \frac{-1}{4} (x - 4)[/tex]

Answer:

9 weeks at least to have at least 50 dollars.

Step-by-step explanation:

Well 6 dollars each week and to get AT LEAST 50 dollars you need to save for 9 weeks.

Well 9*6=54

If you do it for 8 you’d only get 48 which is not at least 50 but 54 is.

So 9 weeks is the final answer.

50≤54

50 isn’t less then 48

Answer:

D, (1,2)

Step-by-step explanation:

It all comes down to substitution. In this case the coefficient of x is 3 and the coefficient of y is 4. The format of these coordinates being (x,y).

1. Plug in your x value (1 in this circumstance) and solve:

3(1) + 4y < 12

3 + 4y < 12

2. Plug in your y value (2 in this circumstance) and solve:

3 + 4(2) < 12

3 + 8 < 12

3. Solve

3 + 8 = 11

11 < 12

The first one is less

Answer:

5

Step-by-step explanation:

The given two triangles are similar , therefore ,

⇒ 5x /20 = 45/36

⇒ x/4 = 5/4

⇒ x = 5/4 × 4

⇒ x = 5

Hence the value of x is 5.

Answer:

[tex]y=x+3[/tex]

Step-by-step explanation:

What we need to know

1) Rewrite the equation x - y = 5 into slope-intercept form and identify the slope

[tex]x - y = 5[/tex]

Subtract both sides by x

[tex]x - y -x= -x+5\\-y= -x+5[/tex]

Divide both sides by -1

[tex]y= x-5[/tex]

Now, we can tell clearly that the slope (m) of this line is 1. Therefore, a line parallel to this would also have a slope of 1.

Plugging 1 as m into [tex]y=mx+b[/tex], we get:

[tex]y=x+b[/tex]

2) Find the y-intercept (b) of the line parallel to [tex]y= x-5[/tex] and find the final equation

[tex]y=x+b[/tex]

Plug in the given point (-5,-2)

[tex]-2=-5+b[/tex]

Add 5 to both sides

[tex]-2+5=-5+b+5\\3=b[/tex]

Therefore, the y-intercept of this line is 3. Now, plugging this back into our original equation, we get:

[tex]y=x+b\\y=x+3[/tex]
