Answer: Option 'e' is correct.
Step-by-step explanation:
Since we know that
Discrete data are those data which is countable and it is expressed in exact numerical form.
Continuous data are those data which is lie within the interval and it varies so it does not expressed in exact numerical form.
Here, the number of iphones sold today at an Apple store is countable and it can be expressed in exact numbers.
So, it is considered as discrete.
Hence, Option 'e' is correct.
The angle between their paths to the nearest degree is 68⁰.
<h3>
Displacement of each boats after 45 minutes</h3>
first displacement, a = 15 km/h x (45/60)
first displacement, a = 11.25 km
second displacement, b = 18 km/h x (45/60)
b = 13.5 km
<h3> Angle between their paths to the nearest degree</h3>
c² = a² + b² - 2ab(cosθ)
2ab(cosθ) = a² + b² - c²
cosθ = (a² + b² - c²)/(2ab)
cosθ = (11.25² + 13.5² - 14²) / (2 x 11.25 x 13.5)
cosθ = 0.371
θ = arc cos(0.371)
θ = 68.22 ⁰
Thus, the angle between their paths to the nearest degree is 68⁰.

Answer:
9
Step-by-step explanation:
The sum of ten and four gives you 14, so if the other line has the same angle, 5 and 9 give you 14
Answer:
length = x+6
width = x-6
Step-by-step explanation:
The area of rectangle is:
where A is area, l is length and w is width.
We know the area of this rectangle or table since we are given A = x^2-36.
First, substitute A = x^2-36 in.
Then we factor x^2-36, use the difference of two squares:
Compare the terms.
First, we have to understand that length is always longer or greater or have more values than width.
Hence length cannot be x-6 and width cannot be x+6 either.
Thus:
Draw a perpendicular at x=2
Now reflect each coordinates across there
(2,2)
- Will remain same as x=2 is on Q1 positive side
(8,4)
- x coordinate=2-8=-6
- y coordinate=4(same)
New coordinate (-6,4)
(6,8)
- x coordinate=2-6=-4
- y coordinate is same
New coordinate
