The distance of the flag pole from point Y is 0.8 km and it is placed at an bearing of N40°E
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Sine rule shows the relationship between the sides and angles of a triangle.
The triangle formed has angles A = 10°, B = 50°, C = 120°, c = 4 km, a = distance from point y.
Hence:
a / sinA = c / sinC
a / sin(10) = 4 / sin(120)
a = 0.8 km
The distance of the flag pole from point Y is 0.8 km and it is placed at an bearing of N40°E

It is systematic because they are going every tenth person, in a random manner.
Answer:
sinx = √2/3
Step-by-step explanation:
cos2x = 1-2sin²x
5/9 = 1-2sin²x
2sin²x =1-5/9
2sin²x = 4/9
sin²x = (4/9)/2
sin²x = (4/9)*(1/2)
sin²x = 2/9
sinx = √2/3
Answer:
These outcomes are disjoint.
Step-by-step explanation:
(a) Are the outcomes none, small, and big disjoint
If they are disjoint, the sum of the total number of each has to be equals to the number of emails.
We have:
3921 emails.
549 with no numbers.
2827 with only one or more small numbers
545 had at least one big number.
549 + 2827 + 545 = 3921
Since the sum is equals to the number of emails, these outcomes are disjoint.
The answer would be (The two ranges are close together, so there are probably no outliers in this set. )
