A continuous data set is where you can plot every point (even very, very small decimal numbers) because the unit can be measured in parts of the whole.
A discrete data set is where you can only plot the units in whole values. For example, if you were plotting the number of people, you can't have a part of a person.
Weight is measured in lbs which can be measured in parts of the lb (such as 100.005 lbs) so it is continuous.
Answer: Continuous data set
The ratio of two sides of one right triangle is the same of the corresponding sides of any its similar triangles.
Call a, b, c the sides of a right triangle and A, B, C the sides of any of its similar triangles.
Then a/b = A/B, which means that this ratio is a constant.
The same for a/c = A/C, and b/c = B/C.
Even, the same is true for the inverses: b/a = B/A; c/b = C/B, and d/a = C/A.
Then, you can define a function for every one of these ratios. Those functions are the trigonometric functions.
Answer:
69 years
Step-by-step explanation:
Given that:
Let year of birth = x
This year = 2020
Year of 25th birthday = x + 25
Year of 55th birthday = x + 55
Present age = 2020 - x
Hence,
x + 2020 - (x + 25 + x + 55) + (2020 - x) = 58
x + 2020 - (2x + 80) + (2020 - x) = 58
x + 2020 - 2x - 80 + 2020 - x = 58
-2x + 4040 - 80 = 58
-2x + 3960 = 58
-2x = 58 - 3960
-2x = - 3902
x = 1951
Birth year = 1951
,
Hence, age =
2020 - 1951 = 69 years
Question should be sin 20 cos 10 + cos 20 sin 10
remember sin (a+b) = sin a cos b + cos a sin b ?
sin 20 cos 10 + cos 20 sin 10
= sin (20+10)
= sin 30
= 1/2
Answer: y is the dependent variable
Step-by-step explanation:
In mathematics, a function is a rule for taking an input and providing an output.
A symbol that stands for an arbitrary input is called an independent variable.
A symbol that stands for an output that depends on the value of a independent variable is called a dependent variable.
y = 12x } Function
x is the independent variable = arbitrary number of hours worked.
y is the dependent variable because depends on the value of x.
