Harry made $10,000 that the end of the year.
Answer:
no solutions
Step-by-step explanation:
10x+2y=42
5x+y=20
Multiply the second equation by -2 to use elimination
-2(5x+y)=20*-2
-10x -2y = -40
Add this to the first equation
10x+2y=42
-10x -2y = -40
--------------------------
0 = 2
This is never true. This means there are no solutions
Answer:
The IQR is a better measure of spread for dance competitions than for badminton games.
Step-by-step explanation:
I understand from "Dance Competition box plot has interquartile ranges approximately between 60 and 130" that quartile 1 is at 60 and quartile 3 is at 130, then, the interquartile range (IQR) is 130 - 60 = 70.
Similarly, from Badminton box plot, quartile 1 is at 90 and quartile 3 is at 150, then, the interquartile range is 150 - 90 = 60.
IQR is a measure of statistical dispersion, that is, as IQR increase, spread increase.
Answer:
Step-by-step explanation:
By applying Pythagoras theorem in the triangle given in the picture,
(Hypotenuse)² = (leg 1)² + (leg 2)²
PO² = (15)² + 8²
PO² = 225 + 64
PO = √289
PO = 17
By applying sine rule in the given triangle,
sin(x°) = 
=
cos(y°) = 
Relation between the ratio of sin(x) and cos(x) will be,
= 
=
