Perimeter = 2(x-4) + 2(x+6)
= 2x-8+2x+12
= 4x+4

area= (x-4)(x+6)
= x²+2x-24

irina [24]

Answer: Our required probability is 0.99338.

Step-by-step explanation:

Since we have given that

n = 100

p = 0.200

So, $np=100\times 0.2=20>5$

So, we can apply normal approximation.

Mean = 20

Standard deviation = $\sqrt{npq}=\sqrt{100\times 0.2\times 0.8}=\sqrt{16}=4=\sigma$

Since $z=\dfrac{\bar{X}-\mu}{\sigma}$

So, Probability that fewer than 30 but a packet after testing a free sample is given by

$P(X$

Hence, our required probability is 0.99338.
