Answer:
x = 10
Step-by-step explanation:
Since the line segment bisects ∠A the following ratios are equal
= , that is
= ( cross- multiply )
8(2x + 1) = 12(x + 4) ← distribute both sides
16x + 8 = 12x + 48 ( subtract 12x from both sides )
4x + 8 = 48 ( subtract 8 from both sides )
4x = 40 ( divide both sides by 4 )
x = 10
For this case we must simplify the following expression:
We rewrite the expression as:
We multiply the numerator and denominator by:
We use the rule of power in the denominator:
Move the exponent within the radical:
Answer:
<h2> S.O.L.V.E</h2>
- Study the problem
- Organize your facts
- Line up the problem
- Validate
- Explain

<h2>
<em>step</em><em> </em><em>1</em><em> </em><em>:</em><em>study</em><em> </em><em>the</em><em> </em><em>problem</em><em> </em></h2>
<em>write</em><em> </em><em>down</em><em> </em><em>your</em><em> </em><em>fact</em><em> </em><em>or</em><em> </em><em>what</em><em> </em><em>you</em><em> </em><em>know</em><em> </em><em>about</em><em> </em><em>the</em><em> </em><em>problem</em><em>. </em><em>also</em><em> </em><em>crossout</em><em> </em><em>unnecessary</em><em> </em><em>parts</em><em> </em><em>of</em><em> </em><em>the problem</em><em> </em><em>and</em><em> </em><em>highlight</em><em> </em><em>important</em><em> </em><em>information</em><em>.</em>
example: X = hours
<h2> </h2><h2>Step 2: organize your facts</h2>
organize your facts means put in order ,write what it means etc.
example: the problem say rebbeca has 3 3 times as much candy than Sara. what does the problem mean ?
<h2>Step 3 : line up your strategy. </h2><h3> what are your plans for solving this problem ? what operation will u do ? how much step is in this problem ? does this make sense ? in line up your strategy u have to think about why I'm doing this? how I will do this etc.</h3>
<h2>Step 4 : validate </h2>

The standard deviation of a binomial variable is
sqrt(n*P*(1-P))
where n is the sample size and P is the probability of one of the outcomes.
The sample size is 55 and we'll assume that both male and female are equally likely outcomes.
standard deviation = sqrt(55*.5*.5) = 3.7081%
44% is 1.6181 standard deviations away from the mean of 50%.
Looking this up on a standard deviation chart gives .0526 probability which we'll round to 0.053</span>
Answer:
A linear function is one that is changing at a constant rate as well as it changes. As for a exponential function is one that changes at a rate that's always proportional to the value of the function.
