Answer:

3/7 chance of picking a red marble.

Step-by-step explanation:

You know that there are 4 non-red marbles and 3 red marbles. You know this because of the statement "he odds against picking a red marble from a bag are 4:3.".

Now you must both amounts of marbles to find the total.

3+4=7

now,

we know that we are looking for the odds of picking a red marble.

So, 3 red marbles in a bad of 7 marbles.

Our odds are 3/7!

The surface area of a cube is 1,350 m2. Find the volume of the cube.​
lilavasa [31]

Answer:

3375

Step-by-step explanation:

The surface area formula for a cube is:

A = 6 a^2

We know what the area is so plug it into the equation:

1350 = 6 a^2

225 = a^2

a = 15

Now plug a = 15 into the equation for volume of a cube:

V = a^3

V = 15^3

V = 3375

Explain why f(x)=1/(x-3)^3 is not continuous at x=3
Bingel [31]
F(x)=1/(x-3)^3

The denominator can't be equal to zero (we can't divide by zero), then:
(x-3)^3 different 0
cubic root both sides:
cubic root [ (x-3)^3 ] different cubic root (0)
x-3 different 0
Adding 3 both sides:
x-3+3 different 0+3
x different 3

Then the function f is not defined at x=3

Answer: Option <span>b) f is not defined at x= 3</span>

PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE HELP ME!!!!!!!! THATS ALL. I WILL GIVE POINTS, FAN, MEDAL. PLEASE, I AM SO BAD AT MATH
dezoksy [38]
Please try leaving out the "I'm so bad at math" part.  It doesn't help.

The given inequality is   <span>4x + y > −6.  Because of the > symbol, we must use a dashed line, not a solid one.  Let's solve this for y:    y > -4x - 6.

This (dashed) line has a slope of -4 and a y-intercept of (0,-6).

Plot (0,-6).  Then, with your pencil pt. on that, move 1 unit to the right and then 4 units down.  Plot a new point there, at (1, -10).  Draw your dashed line thru those 2 pts.  Then, because we have y > -4x - 6, shade the area ABOVE this line.  Done.</span>
