Answer:

m∠2 = 16° or 25°

Step-by-step explanation:

The sum of angles 1 and 2 is congruent to angle CED.

20° +(x^2)° = (9x)°

x^2 -9x +20 = 0 . . . . . divide by °, put in standard form

(x -5)(x -4) = 0 . . . . . . . factor

x = 5 or 4

m∠2 = (x^2)° = (5^2)° or (4^2)°

m∠2 = 16° or 25°

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.
