Step-by-step explanation:
1. The sample of this study is 250 households in a cedar bluff. Population sample means the total number of units or participants are participating in a study to determine the result.
2. The population of interest refers to the objects and measurement through which a population sample can be measured to make a bold decision. Here, 4 pounds of garbage per day is a measurement to make a valuable decision to validate the study.
1/2 I think. Even though you already got heads 10 times you still have a 1/2 chance to get it again.
As we know, two weeks is 14 days. If they caught 42 mahi mahi fish in 14 days, then they cought approximately 42 / 14 = 3 mahi mahi fish a day.
Hopefully it'll help you :)
Answer:
It returns the angle whose cosine is a given number.
Step-by-step explanation:
For every trigonometry function, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arccos button may be labeled arccos, or sometimes cos-1.) So the inverse of cos is arccos etc. When we see "arccos x", we understand it as "the angle whose cosine is x"
cos30 = 0.866 Means: The cosine of 30 degrees is 0.866
arccos 0.866 = 30 Means: The angle whose cosine is 0.866 is 30 degrees.
Use arccos when you know the cosine of an angle and want to know the actual angle.
Answer:
Step-by-step explanation:
An isosceles triangle has two equal sides and the two opposite angles to the sides to be equal.
Given that; RP = RS, RQ and PS are common,
RP = SQ (opposite sides of parallelogram RPQS)
PQ = RS (opposite sides of parallelogram RPQS)
ΔRPS = ΔQPS (congruence property)
Thus comparing triangles PQR and SQR,
= 
(similarity property)
<PRS = <PRQ + <SRQ (bisection of included <PRS)
<PQS = <PQR + <SQR (similatity property to <PRS)
= 
(congruence property)
But, SRQ = PQR
So that;
Therefore by Side-Angle-Side (SAS), the required additional fact is:
