Answer: A negative linear association
Step-by-step explanation:
From the given table in the picture , it can be seen that as the time is increasing the amount of water in tank decreases, it indicates that there is a negative association between the two variables.
Also, the rate of change in amount of water is constant as 0.5 gallon per hour.
It implies there is a linear association.
Now, the scatter plot for this data represents there is a negative linear association between the number of hours and the amount of water in the tank, in gallons.
What are the missing numbers?
Answer:
A) 15 and 16
Step-by-step explanation:
The square root of 250 is 15.8, so it falls between:
15 and 16
The solution is, The length of the altitude of the equilateral triangle is 9.
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
here, we have,
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
here, we have,
The given triangle is an equilateral triangle.
Here, a is a median which bisects the base. It also serves as an altitude, as it is an equilateral triangle.
As the triangle can be divided into two right angle triangle,
Using Sine.
Sine = Opposite / Hypotenuse
sin 60° = a / (6√3)
But sin60° = √3/2
so, we get,
√3/2 = a/(6√3)
Cross multiply
2*a = 6√3 * √3
2a = 6 * √(3*3)
2a = 6*3
a = 6*3/2
a = 3*3
= 9
Hence, Option E. The solution is, The length of the altitude of the equilateral triangle is 9.
