Answer:
x=-2.25
Step-by-step explanation:
Answer:
35 meters
Step-by-step explanation:
Since 1cm=10meters, we can do 3.5cm=how many meters?
To get from 1 to 10 we multiply by 10.
So we can do 3.5x10 to get 35 meters.
Hope this helps!

"<span>What is the general process for solving an equation with one variable?"...
Typically when solving an equation with one variable, your objective is to
isolate the variable on one side of the equation. This can be done adding/subtracting number to cancel them out on one side. You can also multiply/divide coefficients in order to isolate a variable.
Example:</span>
![2x+4=64](https://tex.z-dn.net/?f=2x%2B4%3D64)
<span>Add
-4 to both sides to isolate the variable.
</span>
![(2x+4)+(-4)=(64)+(-4)](https://tex.z-dn.net/?f=%282x%2B4%29%2B%28-4%29%3D%2864%29%2B%28-4%29)
<span>
Simplify.
</span>
![2x=60](https://tex.z-dn.net/?f=2x%3D60)
Divide both sides by
2 to isolate the variable on one side.
![(2x)/2=(60)/2](https://tex.z-dn.net/?f=%282x%29%2F2%3D%2860%29%2F2)
![x=30](https://tex.z-dn.net/?f=x%3D30)
Hope this helps.

Critical value z_{0.05}=-1.645
Decision Rule, Reject H if z< -1.645
We do not reject the null hypothesis.
<h3>What is the
Decision?</h3>
Generally, the equation for the hypothesis is mathematically given as
H P=0.3
H2:P<0.13
Therefore
![z=\frac{p'-p}{\sqrt{\frac{p(1-p)}{n}}}\\\\\\z=\frac{0.11-0.13 }{\sqrt{\frac{0.13(1-0.13)}{76}}}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bp%27-p%7D%7B%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%7D%7D%5C%5C%5C%5C%5C%5Cz%3D%5Cfrac%7B0.11-0.13%20%7D%7B%5Csqrt%7B%5Cfrac%7B0.13%281-0.13%29%7D%7B76%7D%7D%7D)
z=-0.52
In conclusion, from the table
Critical value z_{0.05}=-1.645
Decision Rule, Reject H if z< -1.645
In conclusion, we do not reject the null hypothesis.

Answer: FIRST OPTION.
Step-by-step explanation:
Regular polygons are those polygons whose sides are equal in length and whose angles are all equal.
By definition each interior angle of a Regular polygon,is:
(In degrees)
Where "n" is the number of sides of the polygon.
Observe the Regular polygon given in the exercise.
Since it has 6 sides, you can conclude that it is an Hexagon. Then:
![n=6](https://tex.z-dn.net/?f=n%3D6)
Substituting into
and evaluating, you get:
![\frac{180 ( 6 -2 )}{6}=120\°](https://tex.z-dn.net/?f=%5Cfrac%7B180%20%28%206%20-2%20%29%7D%7B6%7D%3D120%5C%C2%B0)
Knowing this, you can write the following equation:
![3x=120](https://tex.z-dn.net/?f=3x%3D120)
Finally, you must solve for "x" in order to find its value. This is:
![x=\frac{120}{3}\\\\x=40](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B120%7D%7B3%7D%5C%5C%5C%5Cx%3D40)
