Answer:
Step-by-step explanation:
what do you think it is?
A(1) = 2
a(2) = 4
You can see that the terms are increasing by +2.
so
a(1) = 2
a(2) = 4
a(3) = 6
a(4) = 8
a(5) = 10
a(6) = 12
a(7) = 14
a(8) = 16
a(9) = 18
a(10) = 20
your answer is a(10) = 20.
Based on the random sample of beach lengths taken, the probability of a randomly selected beach having a length of 12 miles is C. 0.
<h3>What is the probability that a beach is 12 miles in length?</h3>
Beach length is considered a continuous variable which takes a numerically positive form because it can have any one of infinite possible values.
As a result, there is no possibility that a beach chosen at random will have a given length of 12 miles which means that the probability is 0.
In conclusion, the probability that a selected beach has a length of 12 miles is 0.

Answer: The blue whale's weight is 150 times heavier than the narwhal's weight.
Step-by-step explanation:
Given: Weight of Blue whale = 
Weight of Narwhal = 
Number of times blue whale's weight is heavier than the narwhal's weight = 
![=\dfrac{3\times10^5}{2\times10^3}\\\\=1.5\times10^{5-3}\ \ \ [\dfrac{a^m}{a^n}=a^{m-n}]\\\\=1.5\times10^2\\\\=1.5\times100=150](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B3%5Ctimes10%5E5%7D%7B2%5Ctimes10%5E3%7D%5C%5C%5C%5C%3D1.5%5Ctimes10%5E%7B5-3%7D%5C%20%5C%20%5C%20%5B%5Cdfrac%7Ba%5Em%7D%7Ba%5En%7D%3Da%5E%7Bm-n%7D%5D%5C%5C%5C%5C%3D1.5%5Ctimes10%5E2%5C%5C%5C%5C%3D1.5%5Ctimes100%3D150)
Hence, the blue whale's weight is 150 times heavier than the narwhal's weight.

Answer:
adjacent angles are 50° and 130°
Step-by-step explanation:
The sum of all 4 angles in a parallelogram is 360°, so the fourth angle must be ...
360° -310° = 50°
Adjacent angles are supplementary, so the other two angles must be ...
180° -50° = 130°
The angles in the parallelogram are either 50° or 130°. Adjacent angles are different.
