Answer:

m = -3

b = 4

Equation: y = -3x + 4

Step-by-step explanation:

The equation for a straight line is y = mx + b.

The line crosses the y-axis at (0,4). So, b (the y-intercept) will be 4.

Now, to find m (the slope). The next point on the line is (1,1). To get there, you go down 3 units (-3) and to the right 1 unit.

Slope is known as rise (change in x-axis) over run (change in y-axis). So, -3 ÷ 1 = -3. m will be -3.

For the equation of the line, just plug the numbers into the equation for a straight line.

y = mx + b

y = -3x + 4

Hope that helps.

Answer: $P\left ( A\right )=0.45$

$P\left ( B\right )=0.32$

Step-by-step explanation:

Given

$P\left ( A\cup B\right )=0.626$

$P\left ( A\cap B\right )=0.144$

and we know

$P\left ( A\cup B\right )=P\left ( A\right )+P\left ( B\right )-P\left ( A\cap B\right )$

$0.626=P\left ( A\right )+P\left ( B\right )-0.144$

$0.77=P\left ( A\right )+P\left ( B\right )$ -------1

as it is given

A and B are independent therefore

$P\left ( A\cap B\right )=P\left ( A\right )\cdot P\left ( B\right )$

$0.144=P\left ( A\right )\cdot P\left ( B\right )$

Substitute value of $P\left ( B\right )$ in 1

$0.77=P\left ( A\right )+\frac{0.144}{P\left ( A\right )}$

on solving $P\left ( A\right )=0.45$

$P\left ( B\right )=0.32$

Andrea has just created a scale drawing of her bedroom room which is 18 feet long by 12 feet wide. The scale drawing shows the l

dalvyx [7]

The width of scale drawing is 4 inches

Step-by-step explanation:

The length of room =L1= 18 ft

The width of room =W1= 12 ft

The scale drawing length=L2 = 6 inches

The scale drawing width W2= x

According to rule of three

$\frac{L1}{L2} = \frac{W1}{W2}$

putting values in equation we get

$\frac{18}{6} = \frac{12}{x}$

$3=\frac{12}{x}$

Re-arranging the equation we get

$x=\frac{12}{3} \\x= 4$

So the width of scale drawing is 4 inches
