Answer:

170.6

Step-by-step explanation:

The tenth place is the first number to the right of the decimal place.

Since we have to round to the tenth place, we can round 170.55 by looking at hundredths place. If the 5 in the hundredths place is greater than or equal to 5 than the tenth place rounds up and if it is less than 5 than the tenth place rounds down. In this case 170.55 would round up to 170.6.

What is x? I will give brainliest if you explain your answer.

horsena [70]

Answer:

x = {0, π/2, 3π/2, 2π}

Step-by-step explanation:

cotx cos x - cot x = 0
cotx( cosx - 1) = 0

1. <u>cotx = 0</u>

x = π/2 + πn
In the interval [0, 2π] we have π/2 and 3π/2

2. <u>cosx = 1</u>

x = 0 + 2πn
In the given interval we have 0 and 2π

<u>So the solution set is:</u>

x = {0, π/2, 3π/2, 2π}

Total blood cholesterol level was measured for each of

laiz [17]

<h3>Answer: Mean = 218.9.</h3><h3>Median = 229</h3><h3>Mode = Zero mode.</h3>

Step-by-step explanation:

Given blood cholesterol level was measured for each of 8 adults (in mg/dL) are:

264, 191, 160, 148, 262, 212, 268, 246

In order to find the mean, we need to add all those 8 numbers and divide by 8.

Therefore, mean = $\frac{264+191+160+148+262+212+268+246}{8} =\frac{1751}{8} =218.9.$

<h3>Mean = 218.9.</h3>

In order to find the median, we need to arrange them in ascending order:

148, 160, 191, 212, 246, 262, 264, 268.

The middle most two values are 212 and 246.

Therefore, median = $\frac{212+246}{2} =\frac{458}{2} = 229.$

<h3>Median = 229.</h3>

$\mathrm{The\:mode\:is\:the\:term\:in\:the\:data\:set\:that\:appears\:the\:most.}$

$\mathrm{If\:there\:is\:more\:than\:one\:term\:that\:appears\:the\:most,\:then\:there\:is\:no\:mode.}$

$\mathrm{Count\:the\:number\:of\:times\:each\:element\:appears\:in\:the\:list}$

$\begin{pmatrix}148&160&191&212&246&262&264&268\\ 1&1&1&1&1&1&1&1\end{pmatrix}$

$\mathrm{The\:most\:common\:element\:is\:not\:unique,\:so\:there\:is\:no\:mode}$

<h3>Therefore, Mode = Zero mode.</h3>
