Angle M equals 45°
Angle N equals 15°
It's 100
Because You multiply the sample proportion to 2000
Let the number of songs owned by Lou be = x.
Kelly has 4 times as many songs as Lou = 4x
Tiffany has 6 times as many songs as Lou = 6x
They all have total of 682 songs
= x + 4x + 6x = 682
11x = 682
x = 682 / 11 . Use your calculator.
x =62.
How many songs Kelly has = 4x = 4*62 = 248 songs.
Kelly = 248 songs.
Answer:
Option D, x = 1
Step-by-step explanation:
In order for that equation to equal to zero, you need the numerator (the top) to equal zero and the denominator (the bottom) to equal literally anything BUT ZERO.
To satisfy the first part we set the top binomial equal to zero.
x - 1 = 0
x = 0 + 1
x = 1
Plug in x = 1 to the bottom to see if it satisfies to second part; we're looking for everything but zero.
(x - 3)(x + 1)
(1 - 3)(1 + 1)
(- 2)(2) = - 4
Your answer is x = 1, option D.
