What is 2 3/2 equal to?

Mathematics
1 answer:
kati45 [8]1 year ago
6 0

Answer:

  (a)  √8

Step-by-step explanation:

You want to know the radical equivalent to 2^(3/2).

<h3>Indices</h3>

The relationship of indices to radicals is ...

  \large{\sqrt[n]{a^m}}={a^{\frac{m}{n}}

<h3>Application</h3>

The given expression can be rewritten as ...

  2^{\frac{3}{2}}=\sqrt[2]{2^3}=\boxed{\sqrt[2]{8}}

__

<em>Additional comment</em>

When the index of the radical is 2, it is usually left off. The radical can be simplified by removing the perfect square factor.

  \sqrt[2]{8}=\sqrt{8}=2\sqrt{2}

Last question, if its wrong expect a pc flying through your window
slavikrds [6]

Answer:

D. 73°

Step-by-step explanation:

The inside angles of a triangle always equal 180° so if we know that a right angle is already 90° we only need one more angle to know all of them:

1. 90° + 17° + ?° = 180

2. 90° + 17° = 107°

3. 180° - 107° = 73°

4. 90° + 17° + 73° = 180

The answer is B for increase of one year the events increase by 0.5

You can do this by using the eqn

y=0.5x-1.3
y=0.5(15)-1.3
y = 7.5-1.3
y = 6.2

y=0.5(16)-1.3
y=8-1.3
y=6.7

6.7-6.2 = 0.5

The following data represent the pulse rates? (beats per? minute) of nine students enrolled in a statistics course. Treat the ni
charle [14.2K]

Answer:

(a)77.4bpm

(b)Mean of Sample 1 = 70.3 beats per minute.  

Mean pulse of sample 2 = 70 beats per minute.

(c)

  • The mean pulse rate of sample 1 underestimates the population mean.
  • The mean pulse rate of sample 2 underestimates the population mean.

Step-by-step explanation:

(a)Population mean pulse.

The pulse of the nine students which represent the population are:

  • Perpectual Bempah      64
  • Megan Brooks               77
  • Jeff Honeycutt               89
  • Clarice Jefferson           69
  • Crystal Kurtenbach       89
  • Janette Lantka              65
  • Kevin McCarthy             88
  • Tammy Ohm                  69
  • Kathy Wojdya                 87

\text{Population Mean} =\dfrac{64+77+89+69+89+65+88+69+87}{9} \\=\dfrac{697}{9} \\\\=77.44

The population mean pulse is approximately 77.4 beats per minute.

(b)Sample 1: {Janette,Clarice,Megan}

  • Janette: 65bpm
  • Clarice: 69bpm
  • Megan: 77bpm

Mean of Sample 1

\text{Sample 1 Mean} =\dfrac{65+69+77}{3} \\=\dfrac{211}{3} \\\\=70.3

Sample 2: {Janette,Clarice,Megan}

  • Perpetual: 64bpm
  • Clarice: 69bpm
  • Megan: 77bpm

Mean of Sample 2

\text{Sample 2 Mean} =\dfrac{64+69+77}{3} \\=\dfrac{210}{3} \\\\=70

The mean pulse of sample 1 is approximately 70.3 beats per minute.  

The mean pulse of sample 2 is approximately 70 beats per minute.

(c)

  • The mean pulse rate of sample 1 underestimates the population mean.
  • The mean pulse rate of sample 2 underestimates the population mean.
