Answer:
5/36 or approximately 13.88...%
Step-by-step explanation:
First, we need to know the probability of rolling a 2 or 3. Because there are 6 sides, the probability is 2/6
Next, we have to find the probability of rolling an even number. With the numbers:
1, 2, 3, 4, 5, 6
1, 3, 5 are odd 2, 4, 6 are even
so, the probability of rolling an even number is 3/6
Finally, multiply the probabilities:
3/6*2/6=5/36
Answer:
5/36 or about 13.88%
F(x) = 3x^32 + 8x^2 -22x +43
The ends of all the polynomials with even degree behave like quadratic functions.
Given the the coefficient of x^32 is positive, the function opens upwards. Then the two ends go up.

4x^2-8x-12 =
(x -3) * (x +1)
4x^2-24x+32

(x -3) * (x +1) * <span>(x -4) * (x -2) = 0
x = 3
x = -1
x = 4
x = 2
All four roots are real numbers and so the graph crosses the x-axis four times. The graph of the equation would resemble a "W".

Valid because 3 x 3 is 9 :))
Answer:
£9.6
Step-by-step explanation:
x = the original price of a CD
£x = 100% of the original price
The price of a CD was decreased by 20% to £7.68.
This means:
£7.68 = 100% - 20%
£7.68 = 80% of the original price
From this, we will find 1% of the original price.
£7.68 ÷ 80 = 1%
£0.096 = 1%
Since the original price ( x ) = 100% of the original price, we will find 100% of the original price.
£0.096 × 100 = 100%
£9.6 = 100%
Therefore, the original price of a CD = £9.6
