TiliK225 [7]

We can calculate for the slope of the line using the formula:

m = (y2 – y1) / (x2 – x1)

From the given values:

m = (4,000 – 10,000) ft / (15 – 0) min

m = -400 ft/min

This means that the altitude is decreasing by 400 ft per minute.

> The slope is –400 . This means that the helicopter descends 400 ft each minute.

<h3>How to calculate a test statistic?</h3>

In Mathematics, the test statistics of a given sample is calculated by using this formula:

$Z=\frac{x\;-\;u}{\frac{\sigma}{\sqrt{n} } }$

<u>Where:</u>

x is the sample mean.

u is the mean.

is the standard deviation.

n is the sample size.

In conclusion, a possible test statistic which can be used to estimate this parameter is the proportion of all students who have "strict" parents or guardians, based on the collected sample.

Merle has an offer from a credit card issuer for a 0% APR for the first 60 days and a 23.19% APR afterwards, compounded daily. W

Andreyy89

To find the rate add 1 to the annual rate divided by 365 days raised to the number of days left in the year minus 1.

r= (1 + 0.2319/365)^305 - 1

r = 0.2138

Now multiply by 100 for the percent:

0.2138 x 100 = 21.38%
