Answer:

23. \frac{4\sqrt{3} }{3}

24. \frac{7\sqrt{3}}{3}

25. 6\sqrt{3}

26. \frac{10\sqrt{3} }{3}

27.  14

28. 4\sqrt{3}

Step-by-step explanation:

To solve these i used SOHCAHTOA

sin=\frac{opposite}{adjacent}\\ cos=\frac{adjacent}{hypotenuse} \\tan=\frac{opposite}{adjacent}

23.

Find the missing side using Tangent

tan(30)=\frac{x}{4}

4*tan(30)=x

\frac{4\sqrt{3} }{3}

24.

Find the missing side using Tangent

tan(30)=\frac{x}{7}

7*tan(30)=x

\frac{7\sqrt{3}}{3}

25.

Find the missing side using Tangent

tan(30)=\frac{x}{18}

18*tan(30)=x

6\sqrt{3}

26.

Find the missing side using Tangent

tan(30)=\frac{x}{10}

10*tan(30)=x

\frac{10\sqrt{3} }{3}

27.

Find the missing side using Tangent

tan(30)=\frac{x}{14\sqrt{3} }

(14\sqrt{3}) *tan(30)=x

14

28.

Find the missing side using Tangent

tan(30)=\frac{x}{12}

12*tan(30)=x

4\sqrt{3}

If we collect a large sample of blood platelet counts and if our sample includes a single​ outlier, how will that outlier appear
Mademuasel [1]
That outlier will appear as a single blip of data, but it will be far away from the central part of the histogram. It will not be that visible if there is a lot of data, since 1 outlying data point will just show a very low height compared to the central data near the mean/median/mode, where there will be higher frequencies and higher bars of data.

If these are the choices:
<span>A.The outlier will appear as a tall bar near one side of the distribution.
B.The outlier will appear as a bar far from all of the other bars with a height that corresponds to a frequency of 1.
C.Since a histogram shows​ frequencies, not individual data​ values, the outlier will not appear.​ Instead, the outlier increases the frequency for its class by 1.
D.The outlier will appear as the tallest bar near the center of the distribution.
</span>
Then the most accurate answer will be B, since it's just a single value with a bar corresponding to a frequency of 1.

Find the new concentration of a solution if 25. 0 mL of water is added to 125. 0 mL of 0. 150 M NaCl solution. What is the final
Lyrx [107]

Part A: The final volume of the new solution is 150 mL.

Part B: The concentration of the new solution is 0.125 M.

<h3>What is the volume?</h3>

The volume of liquid is defined as the amount of liquid in a three-dimensional container. Volume is the quantity of three-dimensional space occupied by a liquid.

Given that the molarity of NaCl solution is 0.150 M, the volume of NaCl solution is 125 mL, the volume of water added is 25 mL.

Part A:

The final volume of the new concentrated solution is calculated as given below.

V = 125  + 25

V = 150 \;\rm mL

The final volume of the new solution is 150 mL.

Part B:

The mole of the NaCl solution is calculated using the molarity formula.

Molarity of NaCl solution = 0.150 M

Volume of NaCl solution = 125mL or 0.125 L

Molarity = Mole of NaCl solution / Volume of the NaCl solution

0.150 = \dfrac {Moles}{Volume}

0,150 = \dfrac {Moles}{0.125}

Moles \;= 0.01875

The moles of NaCl solution is 0.01875 mole which remains same when water is added. Thus, the molarity of the new concentration can be calculated as given below.

Molarity = Moles of NaCl / Volume of new solution

Molarity = \dfrac {0.01875}{0.150}

Molarity = 0.125 M

Hence we can conclude that the concentration of the new solution is 0.125 M.

To know more about the volume, follow the link given below.
