The measure of the convex arc is given by the following relationship:
 WZ + 41 = ZWX
 From here, we must clear We must replace the value of WZ.
 The value of WZ is given by
 WZ=180
 We have then:
 ZWX = 180 + 41
 ZWX = 221 degrees
 Answer:
 
the measure of convex arc upper ZWX is:
 ZWX
 = 221 degrees

Answer:

Yes. There is sufficient eveidence to support  the claim that Wilmington resident's earn more than the national average

Step-by-step explanation:

Given the following;

\alpha=Significance \ Level=0.05\\n=10\\\bar X=60000\\\ s=sample\  \sigma=10000

#We set our hypothesis as:

H_o:\mu\leq 50000\\H_a:\mu>50000

The rejection region of either hypothesis:

P(t>t_o)=0.05, we determine the critical values for this probability in the T distribution table;

t=1.833

=>We reject for all values greater than 1.833, t>1.833.

#We now determine the value of the test statistic as:

t=\frac{\bar X-\mu_o}{s/\sqrt{n}}\\\\=\frac{60000-50000}{10000/\sqrt{10}}\\\\=3.1623

We find that:

t=3.1623>1.833,\ \ \ Reject \ H_o

Hence, there is sufficient eveidence to support  the claim that Wilmington resident's earn more than the national average.

Why is the information in the diagram enough to determine that △LMN ~ △PON using a rotation about point N and a dilation? becaus
natita [175]

Answer:

The correct option is;

Because ∠MNL and ∠ONP are congruent angles

Step-by-step explanation:

From the diagram shown in the question, ∠MNL and ∠ONP are vertically opposite angles as they are formed by crossing of the lines LP and MO making them congruent, that is ∠MNL ≅ ∠ONP

Given that two angle of triangle LMN are congruent to two angles of triangle PON , then by the Angle Angle (AA) rule of similarity, triangle LMN and PON are similar.
