A gondola (cable car) at a ski area holds 50 people. Its maximum safe load is 10000 pounds. A population of skiers has a distrib

fenix001 [56]

Answer: 0.03855

Step-by-step explanation:

Given :A population of skiers has a distribution of weights with mean 190 pounds and standard deviation 40 pounds.

Its maximum safe load is 10000 pounds.

Let X denotes the weight of 50 people.

As per given ,

Population mean weight of 50 people = $\mu=50\times190=9500\text{ pounds}$

Standard deviation of 50 people $=\sigma=40\sqrt{50}=40(7.07106781187)=282.84$

Then , the probability its maximum safe load will be exceeded =

$P(X>10000)=P(\dfrac{X-\mu}{\sigma}>\dfrac{10000-9500}{282.84})\\\\=P(z>1.7671-8)\\\\=1-P(z\leq1.7678)\ \ \ \ [\because\ P(Z>z)=P(Z\leq z)]\\\\=1-0.96145\ \ \ [\text{ By p-value of table}]\\\\=0.03855$

Thus , the probability its maximum safe load will be exceeded = 0.03855

G(x) = 6 - 2x<br> Find g(-4).

sergeinik [125]

Answer:

$\huge \boxed{g( - 4) = 14}$

Step-by-step explanation:

$g(x) = 6 - 2x$

To find g(-4) , substitute the value of x that's - 4 into g(x). That is for every x in g(x) , replace it with - 4

We have

$g( - 4) = 6 - 2( - 4) \\ = 6 + 8 \\ = 14 \: \: \: \: \:$

We have the final answer as

Hope this helps you
