If you roll a dice 48 times how many times would you predict not to roll a 6?

2 answers:

4 0

Hi there!

Since there is a 1/6 chance of rolling a 6, we can just divide 48 by 6 and subtract it from 48:

48 / 6 = 8
48 - 8 = 40

So, the amount of times you would not roll a 6 is 40 times.

Hope this helps!

Answer:

1. 4 $x^{3}$ + 26x² + 4x - 48

2. 2 $x^{3}$ - 23x² + 60x - 32

3. $x^{5}$ + 7 $x^{3}$ - 4x + 2 $x^{4}$ + 14x² - 8

4. 2 $x^{7}$ + $x^{6}$ - 28 $x^{5}$ + 3x + 12

Step-by-step explanation:

To multiply polynomials, simply distribute whatever's outside the largest set of parenthesis, then combine like terms.

1) Distribute the parenthesis (x + 6):

x(4x² + 2x - 8) + 6(4x² + 2x - 8)

4 $x^{3}$ + 2x² -8x + 6(4x² + 2x -8)

4 $x^{3}$ + 2x² -8x + 24x² + 12x - 48

Combine like terms:

4 $x^{3}$ + 26x² + 4x - 48

2) Distribute the parenthesis (x - 8):

x(2x² - 7x + 4) + (-8)(2x² - 7x + 4)

2 $x^{3}$ - 7x² + 4x + (-8)(2x² - 7x + 4)

2 $x^{3}$ - 7x² + 4x + -16x² + 56x - 32

Combine like terms:

2 $x^{3}$ - 23x² + 60x - 32

3) Distribute the parenthesis (x + 2):

x( $x^{4}$ + 7x² - 4) + 2( $x^{4}$ + 7x² - 4)

$x^{5}$ + 7 $x^{3}$ - 4x + 2( $x^{4}$ + 7x² - 4)

$x^{5}$ + 7 $x^{3}$ - 4x + 2 $x^{4}$ + 14x² - 8

No like terms to combine, so:

$x^{5}$ + 7 $x^{3}$ - 4x + 2 $x^{4}$ + 14x² - 8

4) Distribute the parenthesis (x + 4):

x(2 $x^{6}$ - 7 $x^{5}$ + 3) + 4(2 $x^{6}$ - 7 $x^{5}$ + 3)

2 $x^{7}$ - 7 $x^{6}$ + 3x + 4(2 $x^{6}$ - 7 $x^{5}$ + 3)

2 $x^{7}$ - 7 $x^{6}$ + 3x + 8 $x^{6}$ - 28 $x^{5}$ + 12

Combine like terms:

2 $x^{7}$ + $x^{6}$ - 28 $x^{5}$ + 3x + 12

hope this helps!

On saturday, you golf at a Man Vista golfing where renting clubs cost $3 and each game golfed is $7.50. On Sunday, you golf at p

solmaris [256]

Answer:

3 games

Step-by-step explanation:

Here, the same amount of money was spent at different golf clubs. The amount spent at Man vista golfing is (3 + 7.5g). The amount spent at Pinz golfing is (12 + 4.5g)

We equate both to yield the following:

(3+7.5g) = (12+4.5g)

7.5g - 4.5g = 12 -3

3g = 9

g = 9/3

g = 3

Find the circumference of the circle.

SashulF [63]

Answer:

The circumference of the circle in term of pi = 10π inches

The circumference of the circle us 3.14 as pi = 31.4 inches

Step-by-step explanation:

Given

The radius of the circle = r = 5 in

We know that diameter is twice the radius.

so d = 2r = 2(5) = 10 in

<u>Finding the circumference of the circle in terms of pi</u>

Using the formula to find the circumference of the circle

C = dπ

C = 10×π

C = 10π inches

Thus, the circumference of the circle in term of pi = 10π inches

<u>Finding the circumference of the circle using π = 3.14</u>

We know that the formula to find the circumference of the circle

C = dπ

Given

π = 3.14

substituting π = 3.14 to find the circumference of the circle

C = 10×3.14

C = 31.4 inches

Thus, the circumference of the circle = 31.4 inches
