Answer:
1/8
Step-by-step explanation:
An exponent signifies repeated multiplication, so you have ...
![\dfrac{8^3}{8^4}=\dfrac{8\cdot 8\cdot 8}{8\cdot 8\cdot 8\cdot 8}=\dfrac{8\cdot 8\cdot 8}{8\cdot 8\cdot 8}\cdot\dfrac{1}{8}\\\\=\boxed{\dfrac{1}{8}}](https://tex.z-dn.net/?f=%5Cdfrac%7B8%5E3%7D%7B8%5E4%7D%3D%5Cdfrac%7B8%5Ccdot%208%5Ccdot%208%7D%7B8%5Ccdot%208%5Ccdot%208%5Ccdot%208%7D%3D%5Cdfrac%7B8%5Ccdot%208%5Ccdot%208%7D%7B8%5Ccdot%208%5Ccdot%208%7D%5Ccdot%5Cdfrac%7B1%7D%7B8%7D%5C%5C%5C%5C%3D%5Cboxed%7B%5Cdfrac%7B1%7D%7B8%7D%7D)
Answer: 41 degrees
Step-by-step explanation:
measure of angles in a triangle is 180 degrees
So
87 + 52 + ? = 180
139 + ? = 180
? = 41
Whatever the mean pregnancy length is, the standard deviation is 16. So it is WITHIN 32 days meaning that it could be one standard deviation of 16 back from the mean or one above the mean. And according to the empirical rule or something called like that, the percentage of one standard deviations form the mean is 68% theoretically. So 68% is your answer.
Answer:
Step-by-step explanation:
That exterior angle of 111 is equal to the sum of the triangle's remote interior angles. We add the 37 + 35 to get a total angle measure of 72. That means that the base angle on the right is 111 - 72 = 39. That 39 degree angle is vertical to x; that means that x = 39 as well.
