Answer:

1/24 ≈ 4.2%

Step-by-step explanation:

P(head) = 1/2

P(4) = 1/6

P(2 heads and 4) = (1/2)² (1/6) = 1/24 ≈ 4.2%.

Find two numbers whose difference is 176 and whose product is a minimum.

Zanzabum

Let the two required numbers be x and y, then x - y = 176, thus y = x - 176.

Let the product of the two numbers be represented by

$P = xy x(x - 176) = x^2 - 176x$

For the product to be minimum, $\frac{dP}{dx} =0$

$\frac{dP}{dx} =2x - 176=0 \\ \\ \Rightarrow2x=176 \\ \\ \Rightarrow x=88$

Thus, y = 88 - 176 = -88

Therefore, the two numbers are 88 and -88.

Answer:

(x - 1) x (5x + 4)

Step-by-step explanation:

5 x 2 – 4 = 6

5 x 4 – 4 = 16

6 x 2 – 11x – 4 = 56

5 x 2 – x – 4 = (x - 1) x (5x + 4)
