Answer: 0.58

Step-by-step explanation:

Step 1 : Caroline buys fruit and buys cd ( buys both) = 0.12 ( 0.4 x 0.3)

Step 2 : Caroline buys fruit and not cd = 0.28 ( 0.4 x 0.7)

Step 3 : Caroline doesn't buy fruit but buys cd = 0.18 ( 0.6 x 0.3 )

STEP 4 (FINAL STEP) : Add all the probabilities ( 0.12 + 0.28 + 0.18)

Answer:

Plot the points in black and connect them.

Plot the point in blue and count up 3 and to the right 1. Plot and connect the points.

Step-by-step explanation:

Using your cursor/mouse, you will first choose the color black. Then you will plot the points given to you (2,2) and (5,8) by first finding the x-coordinate of (x,y). Start at 2 on the x-axis. Follow the grid line up two units so you will also be at the 2 on the y-axis. Plot or draw a dot/circle on this grid line. Go back to the x-axis and start again at 5 on the x-axis. Follow the grid line up eight units so you will also be at the 8 on the y-axis. Plot or draw a dot/circle on this grid line. Connect the dots for your line.

Using your cursor/mouse, you will choose the color blue. Then you will plot the point given to you (10,5) by first finding the x-coordinate of (x,y). Start at 10 on the x-axis. Follow the grid line up five units so you will also be at the 5 on the y-axis. Plot or draw a dot/circle on this grid line. Instead of plotting another point. This time you will count from the blue point up three units and over to the right one. Mark this grid line as a point. Now connect them.

What is x+8y=-15 7x+8y=-19

lisabon 2012 [21]

You would subtract the x and move it over to the other side so your equation would be
8y= -15 + x
you would then divide everything by 8 so you can have y on its own so it would be
y= -15/8 + x/8
so your final equation is
y=-15/8 +8x

for the second equation it’s the same thing, you subtract 7x
8y= -19 + 7x
divide by 8
y= -19/8 +7/8x

The area of a square is 160x^5y^2. What is the length of one side?

Aleksandr [31]

------------------------------------------------------------------
Formula of area of square
------------------------------------------------------------------
Area of square = Length x Length
Area of square = Length2

------------------------------------------------------------------
Given information
------------------------------------------------------------------
Area of square = $160x^5y^2$

------------------------------------------------------------------
Find length
------------------------------------------------------------------
$length^2 = 160x^5y^2$
$length = \sqrt{160x^5y^2}$
$length = 4y\sqrt{10x^5}$

-----------------------------------------------------------------
$\Longrightarrow \ Answer: \boxed {\boxed{ 4y\sqrt{10x^5} }}
$
