The empirical rule states that approximately 68/95/99.7% of a normal distribution lies within 1/2/3 standard deviations. So the answer is 68%.
Answer:
d=60°
Step-by-step explanation:
Both angles are equal to each other because they are vertical angles and are therefore congruent.
Answer: B
Step-by-step explanation: you multiply 25 x 13 + 150
5 to the power of 4 is equal to 5 x 5 x 5 x 5, which equals 625.
5 to the power of 6 is equal to 5 x 5 x 5 x 5 x 5 x 5, which equals 15625
So the value of 5 to the power of 4 over (divide) 5 to the power of 6 is the same as 625 divided by 15625, which equals 0.04.
A shorter way is you can do this is to cancel like terms:
<span> <u> 5 x 5 x 5 x 5 </u></span><u> </u>
5 x 5 x 5 x 5 x 5 x 5
You can cancel 4 fives on the top with 4 of the 5's on the bottom and you are left with
<u> 1 </u>
5 x 5
or 1/25 which is also equal to 0.04.
Hope this helps.
Have a blessed day!

Answer:
Step-by-step explanation:
Because x^5 has 5 members. When you group them into 2 members each, there is one x left over. This is most easily seen if you try it with numbers.
The clearest way is to pick something that is not a perfect square to start with.
6 * 6 * 6 * 6 * 6
6^2 is a perfect square. It is grouped into 2 groups. Each one is a 6
So 6^2 = 36. 36 is a perfect square.
You should note that 6 ^3 is not a perfect square. One of the 6s is unmatched and you get a fraction when you square root 6^3.
6 * 6 * 6 = 216. The square root of 216 is 14.697... which goes on forever.
6^4 is a perfect square.
6^4 = 1296 The square root of 1296 is 36.
