Answer:  The correct option is

(C) b = 5.

Step-by-step explanation:  We are given to find the value of variable b in the following equation :

8-2b=-2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To find the value of b, we must solve the given equation.

From equation (i), we get

8-2b=-2\\\\\Rightarrow 2b=8+2\\\\\Rightarrow 2b=10\\\\\Rightarrow b=\dfrac{10}{2}\\\\\Rightarrow b=5.

Thus, the required value of b is 5.

Option (C) is CORRECT.

What is an equation of the line that passes through the points (0, 3) and (5, -3)?
shepuryov [24]

Answer <u>(assuming it can be in slope-intercept form)</u>:

y = -\frac{6}{5} x+3  

Step-by-step explanation:

1) First, use the slope formula m =\frac{y_2-y_1}{x_2-x_1} to find the slope of the line. Substitute the x and y values of the given points into the formula and solve:

m =\frac{(-3)-(3)}{(5)-(0)} \\m = \frac{-3-3}{5-0}\\m = \frac{-6}{5}

So, the slope is -\frac{6}{5}.  

2) Now, use the slope-intercept formula y = mx + b to write the equation of the line in slope-intercept form. All you need to do is substitute real values for the m and b in the formula.

Since m represents the slope, substitute -\frac{6}{5} for it. Since b represents the y-intercept, substitute 3 for it. (Remember, the y-intercept is the point at which the line hits the y-axis. All points on the y-axis have an x-value of 0. Notice how the given point (0,3) has an x-value, too, so it must be the line's y-intercept.) This gives the following equation and answer:

y = -\frac{6}{5} x+3

Is the amount of rain in city upper b during april a discrete random​ variable, a continuous random​ variable, or not a random​
larisa [96]
Answer: It is a continuous random variable.

The amount of rain is a continuous random variable because it can take on all of the numbers on a number line.

For example, the actual amount of rain in April could be 1 inch. Or 1.4 inches. Or 1.45 inches. Or 1.452020980234 inches. There are an infinite possibilities for the amount of rainfall.
