Answer:

C) Impossible

Step-by-step explanation:

Since there are no blue cards, the probability that you'd draw one is 0/12, which means that there is no chance you'll draw one.

Find the requested information based on the given facts. Base: $54,300: Total Sales: $950,000; Commission: 2.75% Determine the t

Dafna11 [192]

Answer:

$871068.25

Step-by-step explanation:

Given the base of starting the business is $54300 and the total sale after the business is $950000.

Therefore, the profit of the business is $(950000-54300) = $895700.

Now, the commission has to be deducted from the profit at the rate of 2.75% of the profit.

Hence, total profit of the business is given by

895700 [1 - $\frac{2.75}{100}$ ] = $871068.25 (Answer)

3. Suppose you are testing H0 : µ = 20 vs H1 : µ > 20. The sample is large (n = 71) and the variance, σ 2 , is known. (a) Fin

LUCKY_DIMON [66]

Answer:

We reject the null hypothesis.

Step-by-step explanation:

We are given the following information in the question:

Sample size, n = 71

Population variance is known.

Level of significance, α = 0.08

$z_{\text{stat}} = 1.56$

The null and alternate hypothesis are:

$H_{0}: \mu = 20\\H_A: \mu > 20$

We use one-tailed z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} } = 1.56$

Now, $z_{critical} \text{ at 0.08 level of significance } = 1.41$

Since,

$z_{stat} > z_{critical}$

We fail to accept the null hypothesis and reject it and accept the alternate hypothesis.

Solve for x round to the newest 10th i’d necessary

docker41 [41]

Answer:

x = 43.7°

Step-by-step explanation:

Reference angle (θ) = x°

Opposite side length = 43

Adjacent side length = 45

Apply the trigonometric function, TOA, which is:

Tan θ = Opp/Adj

Substitute

$Tan(x) = \frac{43}{45}$

$x = Tan^{-1}(\frac{43}{45})$

x = 43.7° (nearesth tenth)
