Answer:

0

Step-by-step explanation:

Let X  to be a random variable that looks a binomial distribution which denoted the number of employees out of the 281 who earn the prevailing minimum wage or less

The sample size n = 281

The population parameter p = 5% = 0.05

Using normal approximation for the mean.

\mu = np

\mu = 281\times 0.05

\mu = 14.05

The standard deviation is:

\sigma = \sqrt{np(1-p)}

\sigma = \sqrt{281 \times 0.05(1-0.05)}

\sigma = \sqrt{281 \times 0.05(0.95)}

\sigma = \sqrt{13.3475}

\sigma =3.6534

By using continuity correction; the sample mean x is:

x = 30 - 0.5

x = 29.5

The z statistic test can now be as follows:

Z = \dfrac{x-\mu}{\sigma}

Z = \dfrac{29.5-14.05}{3.6534}

Z = \dfrac{15.45}{3.6534}

Z = 4.23

Thus, the probability that company A will get a discount is

P(X ≥ 30) = P(Z >4.23)

= 1 - P(Z < 4.23)

By using the Excel function for the z score 4.23 i.e. "=1 - NORMSDIST(4.23)" we get;

= 0.0000

Leokris [45]

Answer:

see explanation

Step-by-step explanation:

(1)

the sine of an angle = \frac{opposite}{hypotenuse}

(a)

here the opposite is 12 and the hypotenuse is 13

12 is the side opposite ∠DEF ← required angle

(b)

the tangent of an angle = \frac{opposite}{adjacent}

here the opposite is 5 and the adjacent is 12

∠DFE ← required angle

(2)

to calculate AB use Pythagoras' identity in the right triangle

AB² = 2² + 3² = 4 + 9 = 13, hence

AB = \sqrt{13} ≈ 3.6 ( to nearest tenth )

tanB = \frac{2}{3} ⇒ B = 33.7°

tanA = \frac{3}{2} ⇒ A = 56.3°
