Well, as far as I can tell, the mean (average) is the best representation of the data because there is no outlier (a number a lot higher or lower than the rest of the numbers that throws the data off).

√(25 - 10 √(3) + 3)<br> (not as a decimal)
nikitadnepr [17]

Answer:

\huge\boxed{\sqrt{25-10\sqrt3+3}=5-\sqrt3}

Step-by-step explanation:

\sqrt{25-10\sqrt3+3}=(*)\\\\25=5^2\\3=(\sqrt3)^2\\10\sqrt3=(2)(5)(\sqrt3)\\\\(*)=\sqrt{5^2-(2)(5)(\sqrt3)+(\sqrt3)^2}\\\\\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\=\sqrt{(5-\sqrt3)^2}\\\\\text{use}\ \sqrt{a^2}=|a|\\\\=|5-\sqrt3|=5-\sqrt3\\\\^{\text{because}\ 5>\sqrt3\to5-\sqrt3>0}

Mark studied a group of 30 whales. If each will wait approximately 3.8×10 to the fifth power, pounds find the total weight of al
natta225 [31]

Answer:

11.4 x 10 ^ 6

Step-by-step explanation:

  1. First, you have to convert 3.8 x 10^5 out of scientific notation. To do that, multiply 3.8 * 10^5, you'll get 380,000. This is the weight of each whale.
  2. Now multiply the weight of each whale times 30. 380,000 * 30 = 11,400,000
  3. Convert back to scientific notation. 11.4 x 10^6

A similarity transformation maps `Delta`ABC to `Delta`JKL. The measure of `/_A` of preimage `Delta`ABC is 105°. The scale factor
RoseWind [281]

Please note that dilation does not affect angles. Thus, if an image is dilated the angle remains the same and does not change.

Therefore, even if \Delta ABC is dilated to \Delta JKL by a factor of 1.5 (or by any factor for that matter), the linear dimensions of the original triangle \Delta ABC will either get stretched or get shrunk by a factor of 1.5 but the angles of the original triangle will not be affected in any case.

Please note that this is true for all two dimensional geometric shapes.
