Answer and Step-by-step explanation:

First step we can do is find the slope of the line.

To find the slope, use the following equation:

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

(2, 0) will be the ([tex]x_{2}, y_{2}[/tex]) set, and (0, 4) will be the ([tex]x_2, x_1[/tex]) set.

[tex]\frac{0 - 4}{2 - 0} = \frac{-4}{2} = -2[/tex]

The slope of the line is -2.

Don't worry about the inequality part yet, make it look like an equation because you'll be more familiar with it.

y = -2x + b (b is the y-intercept)

The y-intercept is the point where the lines intersects with the y-axis. this y-value is 4.

y = -2x + 4 -- That is the equation of the line.

We see that all values make the inequality true is on the left side of this line. This means that the sign to replace the = sign with is >=, in which the values of y are less than what is plugged in and evaluated for x.

y <= -2x + 4

That is the inequality equation.

Answer:

(8,90°)

Step-by-step explanation:

To get this answer, you multiply the r values together to get 2*4 = 8. At the same time, you add the theta angles to get 45° + 45° = 90°

The general rule is that if A = (r,theta) and B = (s,phi) then

A*B = (r*s,theta+phi)

where the point (s,phi) is a polar form point.

Answer: 96yd²

Step-by-step explanation:

Multiply:

Larger Rectangle: 16 * 8 = 128ft²

Smaller Rectangle: 8 * 4 = 32ft²

Subtract both your solutions:

128 - 32 = 96ft²

Final Answer:

96ft²

Hope this helped! :)

Answer:

B = 185

Step-by-step explanation:

You must divide 3,708 by 20.

3,708 divided by 20 = 185.4 = 185.

Answer:

B

Step-by-step explanation:

3,708/20=185.4

You obviously can't cut of the fries and wings- so u can't keep the .4 so the answer is 185

Answer:

if d=dogs and c=cats then c+20=d

Step-by-step explanation:

Answer:

20 + 7 = 27 dogs

Step-by-step explanation:

If there are 20 more dogs than there are cats, you add the number of cats with how many more dogs. 20 + 7 = 27 dogs.

Answer:

The magnitude of the number is of 26.

Step-by-step explanation:

Magnitude of a complex number:

A complex number has the following format: a + bi

In which a is the real coefficient and b is the imaginary coefficient.

The magnitude of the number is:

[tex]\sqrt{a^2+b^2}[/tex]

What is the magnitude of -10 + 24i?

For this number, a = -10, b = 24. So

[tex]\sqrt{a^2+b^2} = \sqrt{(-10)^2+24^2} = \sqrt{676} = 26[/tex]

The magnitude of the number is of 26.

The linear inequality that represents the graph is: [tex]y \le \frac 23x + \frac 15[/tex]

The line of the inequality passes through the points:

(0,0.2) and (3,2.2)

So, the slope of the line is:

[tex]m = \frac{2.2 - 0.2}{3 - 0}[/tex]

[tex]m = \frac{2}{3 }[/tex]

The equation is then calculated as:

[tex]y =mx + c[/tex]

Where c represents the value of y, when x = 0.

So, we have:

[tex]y =\frac 23x + 0.2[/tex]

Rewrite as:

[tex]y =\frac 23x + \frac 15[/tex]

The down region is shaded, and the line is a closed line.

So, the inequality is:

[tex]y \le \frac 23x + \frac 15[/tex]

Answer:

d.1.96(0.0632)

Step-by-step explanation:

The margin of error for a 95% confidence interval for the population proportion calculated as below:

Given that x = 8

n = Size of the sample = 40 (Large sample)

Sample population: P=x/n = 8/40 = 0.2; q = 1-p = 0.8

Standard error = [tex]\sqrt{pq/n}[/tex] = [tex]\sqrt{0.2(0.8)}/40[/tex] = 0.0682

95% of confidence Z∝ = 1.96

Margin of Error = Z∝ .[tex]\sqrt{pq/n}[/tex]

Margin of Error = 1.96(0.0682)

So, therefore, option d is correct.
