Answer:

The probability of getting a 3 on each die is  \frac{1}{3}

Step-by-step explanation:

Step one

The sample space for tossing two dice is 12

i.e the first die={1,2,3,4,5,6}= 6

and the second die = {1,2,3,4,5,6}= 6

making a total of 12 sample spaces.

Step two

Hence the probability of getting a 3 on each side is

pr(3 on each side) = \frac{1}{6} +\frac{1}{6}

pr(3 on each side) = \frac{1+1}{6} = \frac{2}{6}  = \frac{1}{3}

pr(3 on each side) = \frac{1}{3}

Answer: 9420meters³

Step-by-step explanation:

The formula to calculate the volume of the cylindrical tank will be:

= πr²h.

where,

π = 3.14

r = radius = diameter/2 = 20/2 = 10

h = height = 30

Volume = πr²h

= 3.14 × 10² × 30

= 3.14 × 100 × 30

= 9420meters³

Can anyone please help me with this thank you
san4es73 [151]

Answer:

x= 0, and x=4

Step-by-step explanation:

x² -x  = 3x, we can subtract 3x from both sides

x² -x -3x = 0, combine like terms

x² -4x = 0 , factor x

x *( x-4) = 0, if the product of 2 numbers equals 0 at least one is 0

x=0 and

x-4 = 0, add 4 to both sides

x= 4

What’s the least common denominator for 1/6 and 7/8?
Alexandra [31]

Answer:

24

Step-by-step explanation:

Here's how we construct the LCD:

Factor the denominators 6 and 8:  6 = 2*3 and 8 = 2*2*2

The LCD involves 2*2*2 as well as 3:

LCD:  2*2*2*3 = 24.  Note that 24 is divisible by both 6 and 8.  There is no smaller LCD that is divisible by 6 and 8 both.

Graph the function f(x) = − x4 + 7x3 − 9x2 − 3x + 10 using graphing technology and identify for which values of x the graph is d
jolli1 [7]

In the attached diagram you can see the graph of the function f(x) = -x^4 + 7x^3 - 9x^2 - 3x + 10.

As you can see graph is:

1. increasing from x = −2 to x = −1

2. decreasing from x = 0 to x = 1

3. decreasing and then increasing from x=1 to x=2

4. increasing from x=2 to x=4.

Answer: correct choice is B.
