Answer:

B: The mean will increase

Step-by-step explanation: The outlier is 46, which is way below all the other numbers, which is the definition of an outlier. If we remove a really low number from the set, then the mean(average) will increase.

Write this equation in standard form<br> y + 4 = 2/3 (x+7)
Karo-lina-s [1.5K]

Answer:

y=\frac{2}{3}x+\frac{2}{3}

Step-by-step explanation:

The standard equation of a straight line is of the form:

y=mx+c

We have to convert the given equation into above form.

Simplifying the given equation:

y=\frac{2}{3}x+\frac{14}{3}-4

         =\frac{2}{3}x+\frac{(14-12)}{3}

        =\frac{2}{3}x+\frac{2}{3}.- This is in standard form

where m=c=\frac{2}{3}

<h3>How to complete two column proof?</h3>

We are given that;

∠T ≅ ∠V and ST || UV

From images seen online, the first missing proof is Alternate Interior angles because they are formed when a transversal intersects two coplanar lines.

The second missing proof is Transitive property because angles are congruent to the same angle.

The last missing proof is  Converse alternate interior angles theorem

because two lines are intersected by a transversal forming congruent alternate interior angles, then the lines are parallel.

A lighthouse is located on an island 200 feet from the shore of the mainland as
Deffense [45]

Answer: Approximately d = 208.72

============================================================

Work Shown:

Make sure your calculator is in radian mode

A quick way to check is to compute cos(pi) and you should get -1

cos(angle) = adjacent/hypotenuse

cos(x) = 200/d

cos(0.29) = 200/d

d*cos(0.29) = 200

d = 200/cos(0.29)

d = 208.715135166392 which is approximate

d = 208.72

I rounded to two decimal places since x is rounded in that manner as well. Round however else you need if your teacher instructs.
