Quadrilaterals L M N O and Q R S T are shown. Given that LMNO ≅ QRST, complete the statements. Side LM is congruent to side . An

deff fn [24]

When you have two congruent figures, the vertices are listed in the same order. This means that

Side LM ≅ Side QR, Side MN ≅ Side RS, etc. The same applies for the angles.

Therefore, Side LM ≅ Side QR and Angle MNO ≅ Angle RST.

Answer:

s ≈ 105

Step-by-step explanation:

Given:

The data set: 700, 735, 680, 890, 755, 740, 670, 785, 805, 1050, 820, 750

To find:

The standard deviation of the data

Steps:

To find the standard deviation, first write the computational formula for the standard deviation of the sample.

${s}= \sqrt{\frac{{\sum}{x^2} - \frac{({\sum}{x})^2}{n}}{n - 1}}$

Take the square root of the answer found in step 7 above. This number is the standard deviation of the sample. It is symbolized by $s$ . Here, we round the standard deviation to the nearest whole number.

${s} = \sqrt{10987.878787879} = 104.8231$

Rounding to the nearest whole number:

s ≈ 105
