Answer: 22 units

Explanation:

Given

lead time = 7

mean = 15

 Standard Deviation = 5

service level = 95%

Using the formulae

Safety stock = safety factor ( z value)   x standard deviation  x \sqrt{lead time}

 But

Z value for 95% service level = 1.645 = safety factor

= 1.645 x 5 x \sqrt{7}

=21.76  which estimates to 22units

kkurt [141]

Answer:

P(p>0.38) = P(z>-2.79)

And using the complement rule we got:

P(p>0.38) = P(z>-2.79)=1-P(Z

Explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

Solution to the problem

For this case wwe know that p = 0.52 and n = 99 and we can check if we can use the normal approximation for the proportion distribution.

np= 99*0.52= 51.48>10

n(1-p) =99*(1-0.52) = 47.52>10

So then we can use the normal approximation.

The population proportion have the following distribution

p \sim N(p,\sqrt{\frac{p(1-p)}{n}})

The mean is given by:

\mu_{p} = 0.52

And the standard error is given by:

\sigma_{p} = \sqrt{\frac{0.52*(1-0.52)}{99}}= 0.0502

We want to calculate this probability:

P(p >0.38)

And for this case we can calculate the z score given by:

z = \frac{p \mu_p}{\sigma_p}

And replacing we got:

z=\frac{0.38-0.52}{0.0502} = -2.79

And using this formula:

P(p>0.38) = P(z>-2.79)

And using the complement rule we got:

P(p>0.38) = P(z>-2.79)=1-P(Z

Hi I need 3 sentences abo8ut why you should buy the tesla stock
zhannawk [14.2K]

Answer:

1. The world is shifting to electric vehicles

2. The business is over the profitability hump

3. Optionality could lead to massive new sources of revenue

Explanation

THE EXPLANATION FOR NUMBER 1: In the first half of 2021, global electric vehicle (EV) sales were 2.6 million units. It doesn't sound like a lot. But unit growth was up 160% over the same period last year. That's more than six times faster than the overall auto market.

THE EXPLANATION FOR NUMBER  2:In 2017, famed investor Jim Chanos said about Tesla: "We think the equity is worthless." As silly as the projection looks in hindsight, Tesla CEO Elon Musk has since admitted that the company was about a month away from bankruptcy at the time. Those days are long gone. The company is now solidly profitable with industry-leading gross margins.

EXPLANATION FOR NUMBER 3:

While the company should be praised for the turnaround, many shareholders have their eyes fixed on new markets the company could disrupt. Led by sanguine analysis from Cathie Wood's ARK Invest, and the stock's inclusion in several of ARK's high-profile exchange-traded funds, Tesla now sports a market capitalization of $777 billion.

hope this helps sorry this is alot
