Answer:
The sample observations are not a randomsample, so a test about a population proportion using the normal approximating method cannot be used.
Step-by-step explanation:
The necessary conditions are
The sample must be random and independently selected from the normally distributed population.
n*p and n*q both must be greater than 5
There must be two outcomes "success" and "failure"
The number of trials must be fixed.
From the given information 2), 3)and 4) conditions are satisfied, but not 1) because we are not given that people are selected randomly.
Answer: The sample observations are not a randomsample, so a test about a population proportion using the normal approximating method cannot be used.
Answer:
5
Step-by-step explanation:
4(x+3) is 4x+12
2x+22=4x+12
-2x from both sides
get 22=2x+12
-12 from both sides
get 10=2x
divide by 2 to both sides
get 5
Answer:
C
Step-by-step explanation:
An angle of the measure 
should have the same measure as an angle measured 
because this is periodic. We can then keep subtracting 
from until we get down to the smallest possible positive radian value: 
.
Thus, the answer is C.
The triangles given below in the diagram are similar by; D: The SSS Similarity theorem.
<h3>How to interpret similar triangles?</h3>
From triangle similarity theorems, we know that;
If a segment is parallel to one side of a triangle and intersects the other two sides, then the triangle formed is similar to the original and the segment that divides the two sides it intersects is proportional.
Now, from the given diagram, we see the ratio of corresponding sides are congruent as;
45/30 = 54/36 = 36/24 = 1.5
Thus, the triangles are similar by SSS similarity theorem

Answer:
C) 3
Step-by-step explanation:
2x-y=3
-4x+2y=-6
4x+3y=11
-4x+2y=-6
4x+3y=11
5y=5
<u>y=1</u>
2x-y=3
2x-1=3
2x=4
<u>x=2</u>
2+1=<em><u>3</u></em>
