a new car worth 37000 is depreciating in value by 2000 per year. how many years will the car be worth 17000

The men's world record for swimming 1500.0 m in a long course pool (as of 2007) is 14 min 34.56s. At this rate, how many seconds

Tcecarenko [31]

We must first find the rate taken to cover 1500.0 m within 14 min and 34.56 sec. We can first convert the time into seconds and hence, we have time = 14(60) + 34.56 = 874.56 seconds. Recall that rate = distance/ time. And using the given for the men's world record, we have rate = 1500.0 m / 874.56s = 1.715 m/s Now, to find the time taken to cover 0.350 miles, we can first convert the distance to meters then use the equation given below. time = distance/rate where distance is equal to 0.350(1609) = 563.15 m. Hence, we have time = 563.15 / 1.715 = 328.37 s From this, we can see that it will takes 328.37 seconds to cover 0.350 miles. <span>Answer: 328.37 seconds</span>

An elevator has a placard stating that the maximum capacity is 19201920 lblong dash—1212 passengers. So, 1212 adult male passen

ASHA 777 [7]

Answer:

This means that there is a 1-0.3594 = 0.6406 = 64.06% probability that the elevator is overloaded. This a good chance that the elevator's limit weight will be exceeded. So, this elevator does not appear to be safe.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by

$Z = \frac{X - \mu}{\sigma}$

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X. Subtracting 1 by the pvalue, we This p-value is the probability that the value of the measure is greater than X.

In this problem, we have that:

Assume that weights of males are normally distributed with a mean of 163 lb and a standard deviation of 29 lb.

This means that $\mu = 163, \sigma = 29$ .

We have a sample of 12 adults, and we want to calculate the zscore of THE SAMPLE'S AVERAGE so we need to find the standard deviation of the sample. This is

$s = \frac{\sigma}{\sqrt{12}} = 8.37$

Find the probability that it is overloaded because they have a mean weight greater than 160.

This is 1 subtracted by the pvalue of Z when $X = 160$

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{160 - 163}{8.37}$

$Z = -0.36$

$Z = -0.36$ has a pvalue of 0.3594.

This means that there is a 1-0.3594 = 0.6406 = 64.06% probability that the elevator is overloaded. This a good chance that the elevator's limit weight will be exceeded. So, this elevator does not appear to be safe.
