Answer:
D
Step-by-step explanation:
The unmarked angle of the triangle is also 40o. The triangle is marked with two equal sides (isosceles).
<2 + 40 + 40 = 180 Combine the left
<2 + 80 = 180 Subtract 80 from both sides
<2 = 180 - 80
<2 = 100 degrees.
That's not the answer. We have to solve for x
<2 = x + 106
100 = x + 106 Subtract 106 from both sides
100 - 106 = x
x = - 6
Answer:
![G = R(3 + q^2)](https://tex.z-dn.net/?f=%20G%20%3D%20R%283%20%2B%20q%5E2%29%20)
Step-by-step explanation:
Given the equation,
.
We are to solve for G. In order words, make G the subject of the formula.
Thus:
![3 + q^2 = \frac{G}{R}](https://tex.z-dn.net/?f=%203%20%2B%20q%5E2%20%3D%20%5Cfrac%7BG%7D%7BR%7D%20)
Multiply both sides by R
![(3 + q^2) \times R = \frac{G}{R} \tomes R](https://tex.z-dn.net/?f=%20%283%20%2B%20q%5E2%29%20%5Ctimes%20R%20%3D%20%5Cfrac%7BG%7D%7BR%7D%20%5Ctomes%20R%20)
![R(3 + q^2) = G](https://tex.z-dn.net/?f=%20R%283%20%2B%20q%5E2%29%20%3D%20G%20)
Rewrite
![G = R(3 + q^2)](https://tex.z-dn.net/?f=%20G%20%3D%20R%283%20%2B%20q%5E2%29%20)
You can decide to leave your answer like this or open the parentheses.
7 +9.84 + 13.9 = 30.74 gallons of gas in a week
To solve that question we can think by the following way:
- The first letter can be any of the letters (A, C, T or G). Therefore there are 4 possibilites.
- To choose the second letter of the sequence, any letter also can be chose. So, one more time, there are 4 possibilites.
Using the fundamental principle of counting, we will find out that can be formed
differents sequences (for example, AA, AG, TT, TG, CT...).
Know we know that, we can generalize. If I have
elements and I must choose one of them
times to do a sequence, the total number of sequence that I can form will be
.
In our question, we want to know how many DNA sequence are exactly 29 letters long. As indicated above, the answer for that is
(29 times)
.
Therefore, there are
DNA sequences with exactly 29 letters long.
I hope I've helped you. =D

So 119 out of 250 people had a pool in their backyard...119/250 = 47.6%
so out of 10,000 people, expected value of ones with a pool is :
47.6% of 10,000 ...
0.476 * 10,000 = 4760 people <===
