You need to convert the cartesian coordinates to polar: This means we need to go from (x, y) --> (r, angle)

We can covert, using the following formulas:

Find r:

(x, y) --> (2, 2\sqrt{3})

r^2 = \sqrt{x^2 + y^2}

r^2 = \sqrt{2^2 + (2\sqrt{3})^2}

r = 4

Now, find our angle:

Use the inverse of tan

\tan^{-1} \frac{2}{2\sqrt{3}} = 30\deg

Turn 30 degrees to radian

\frac{\pi}{180} * 30 = \frac{1}{6}\pi

Answer = (4, \frac{1}{6}\pi) = C

Scientists collect data on the blood cholesterol levels (milligrams per deciliter of blood) of a random sample of 24 laboratory
Ludmilka [50]

Answer: (a) There is a clear outlier in the data.

Step-by-step explanation:

The statement relates that sample= 24

Confidence interval= 80.2 to 89.8.

Now the data does not mention anywhere the standard deviation which is an important parameter in using the t-procedure rather we assume that standard deviation is not known. So, the most worrying part is the skewness and the presence of strong outliers in the t-procedure.

So, the option a) is correct meaning a clear outlier in the data.

A snail climbs to the top of a coconut tree 18 meters high. In an hour it will climb 2 meters. But if it go 2 meters, it will sl
kumpel [21]

Answer:

The snail will reach the top of the coconut in 18 hours.

Step-by-step explanation:

If the snail will climb 2 meters in 1 hour but it will slip down one meter for every 2 meters climbed, then the distance traveled will be:

d = 2 m - 1 m = 1 m                                        

Since in 1 hour, it climbs 2 meters minus 1 meter, the time in which the snail will reach the top is:

t = \frac{1 h}{1 m}*18 m = 18 h      

Therefore, the snail will reach the top of the coconut in 18 hours.

I hope it helps you!
