The angle relationship that best describes angles BAC and DAC is adjacent angles
<h3>What are adjacent angles?</h3>
Adjacent angles are two angles that have a common side and a common vertex but do not overlap in any way.
The common vertex of the angle BAE and FAC is A.
The angles share the same vertex and the same side.
Therefore, the angle relationship that best describes angles BAC and DAC is adjacent angles

200 x 0.99. Or you can do 200/100 which is 2. then multiply that by 99 which gets you 99 which is 198.
Answer: a. 170 b. 752
Step-by-step explanation:
The formula to find the sample size is given by :-
, where p is the prior estimate of population proportion.
= Two-tailed z-value for (significance level).
E= Margin of error .
Given : Margin of error = 0.03
Confidence level = 90%=0.90
By z-value table :
a) The president's political advisors estimated the proportion supporting the current policy to be : p= 0.06.
Required sample size :
∴ Required sample size = 170
b) If no prior estimate of population proportion is given , then we assume
p= 0.5
Required sample size :
∴ Required sample size = 752
Y=-4
compared to focus
(3,-7)
vertex is in middle
so
-4 and -7, the average is -5.5
so vertex is (3,-5.5)
and distance from vertex to focus is from -5.5 to -7 or 1.5
focus is below vertex is p is negative
(x-3)^2=4(-1.5)(x+5.5)
(x-3)^2=-6(x+5.5)
D is answer
Hey there!
Exponents are basically multiplying the same number by itself. So, for example (2)(2)(2) is the same as 2³.
Just remember that 2³ is not the same as 2x3. 2³ means 2x2x2.
