Answer: 0.6812
Step-by-step explanation:
Let p be the population proportion of trees are infested by a bark beetle.
As per given: p= 12%= 0.12
Sample size : n= 1000
Number of trees affected in sample = 1000
Sample proportion of trees are infested by a bark beetle. = 
Now, the z-test statistic : 
So, 
Hence, the value of the z-test statistic = 0.6812 .

Answer:
x = 3
Step-by-step explanation:
to be a parallelogram opposite sides have to be equal
so we have
now solve for x
Answer:
<YXZ and <TUS
Step-by-step explanation:
Alternate exterior angles are angles that are found on opposite sides of a transversal and are found just outside each parallel line that the transversal crosses.
Looking at the diagram given and considering the options available, the angles that are alternate exterior angles are:
<YXZ and <TUS
Answer:
Only applicable if the triangle is right (a 90° angle measurement in one corner).
Using Pythagorean’s theorem, that can be answered.
(4.0)^2 + (1.7)^2 = 18.89
(7.7)^2 = 59.29
The legs A and B do NOT equal a hypotenuse of C, so the answer is NO.
