Where is the blue dot on the number line? -1.15 - 1.1 - 1.05

Answer:

X = 25

Step-by-step explanation:

As, 2x + 60° + 4x = 180° (bc they r supplementry)

So, 6x + 30° = 180°

6x = 180° - 30°

6x = 150°

x = 150/6

x = 25

Therefore, answer = 25

Answer:

y = - 2 + [tex]\frac{1}{3}[/tex] x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (6, 0) ← 2 points on the line

m = [tex]\frac{0+2}{6-0}[/tex] = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]

The line crosses the y- axis at (0, - 2 ) ⇒ c = - 2

y = [tex]\frac{1}{3}[/tex] x - 2 , or

y = - 2 + [tex]\frac{1}{3}[/tex] x

Answer:

Proof

Step-by-step explanation:

"The y-intercept is - 2" and now I think the best way to prove the gradient is to prove it mathematically taking coordinates of the line and using:

[tex]m = \frac{y - y}{x - x} [/tex]

So I'll take the coordinates (6,0) and (0,-2) and substitute them in the formula for the gradient.

[tex]m = \frac{ - 2 - 0}{0 - 6} = \frac{ - 2}{ - 6} = \frac{1}{3} [/tex]

I hope this helps.

Step-by-step explanation:

Answer:

The test statistic is Z = 1.157

Step-by-step explanation:

Given that:

The sample size n = 1200

The sample proportion of those that will vote for the Republican candidate is represented by [tex]\hat p = \dfrac{x}{n}[/tex]

[tex]\hat p = \dfrac{620}{1200}[/tex]

[tex]\hat p =0.5167[/tex]

The null and the alternative hypothesis can be computed as:

[tex]H_o: P=0.50 \\ \\ H_a :P>0.50[/tex]

The formula for the one-sample Z-test for the population proportion can be expressed as:

[tex]Z = \dfrac{\hat p - P_o}{\sqrt{\dfrac{P_o(1-P_o)}{n}}}[/tex]

[tex]Z = \dfrac{0.5167 - 0.5}{\sqrt{\dfrac{0.5(1-0.5)}{1200}}}[/tex]

[tex]Z = \dfrac{0.0167}{\sqrt{\dfrac{0.5(0.5)}{1200}}}[/tex]

[tex]Z = \dfrac{0.0167}{\sqrt{\dfrac{0.25}{1200}}}[/tex]

[tex]Z = \dfrac{0.0167}{\sqrt{2.08333333\times10^{-4}}}[/tex]

Z = 1.157

Testing the hypothesis, from the information given, it is found that the test statistic is z = 1.157.

The null hypothesis is:

[tex]H_0: p = 0.5[/tex]

The alternative hypothesis is:

[tex]H_1: p > 0.5[/tex]

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

For this problem, the parameters are: [tex]p = 0.5, n = 1200, \overline{p} = \frac{620}{1200} = 0.5167[/tex]

Hence, the value of the test statistic is:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.5167 - 0.5}{\sqrt{\frac{0.5(0.5)}{1200}}}[/tex]

[tex]z = 1.157[/tex]

The test statistic is z = 1.157.

Answer:

The answer is 60.

Step-by-step explanation:

16(2)0 + 5(2)2•(3)1

(16)(2)(0)+(5)(2)(2)(3)(1)

16×2=32×0=0 + 5×2=10×2=20×3=60×1=60

0+60=60

Answer:

First, find the slope:

The slope is 1/2.

Now we have this much of the equation:

y = 1/2x + b

Plug in the point (0,3) to find the value of b

3 = (1/2)(0) + b

b = 3

Your final equation is y = 1/2x + 3.

Step-by-step explanation:

The equation of the line is y = x/2 + 3 which is passing through the points (-4, 1) and (0, 3) option (B) is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The straight line is shown in the coordinate plane.

The equation of the line passing through the points:

(-4, 1) and (0, 3)

From the two-point we can find the equation of the line:

y - 3 = (3-1)/(0+4)[x]

y = 2/4[x] + 3

y = x/2 + 3

Thus, the equation of the line is y = x/2 + 3 which is passing through the points (-4, 1) and (0, 3) option (B) is correct.

Step-by-step explanation:

The given line in the graph is represented by the equation g(x) = 6 - (3). The correct option is D.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

In the given graph the straight line is represented by the function g(x) = 6 - ( 3 ). The graph of the line is matched with the answer below.
