Answer:
x= 0, and x=4
Step-by-step explanation:
x² -x = 3x, we can subtract 3x from both sides
x² -x -3x = 0, combine like terms
x² -4x = 0 , factor x
x *( x-4) = 0, if the product of 2 numbers equals 0 at least one is 0
x=0 and
x-4 = 0, add 4 to both sides
x= 4
Answer:

Answer:
397,561 copies have been sold to date
Step-by-step explanation:
If 32,600 copies represent 8.2% of the whole
Let's assume the whole is Y
Therefore 8.2% of Y = 32,600 copies
Let's make Y the subject of formula by dividing both sides of the equation by 8.2%
(8.2% x Y) divided by 8.2% = 32,600 divided by 8.2%
Y = 32,600 / 8.2% = 397,561
Answer:
3.2768 feet
Step-by-step explanation:
The situation can be model by h(x)=8*(4/5)^(n-1). For the 5th jump, n=5. The height will be 8*(4/5)^4=3.2768
Answer:
Step-by-step explanation:
Let x be the random variable that represents the data speed.
Given, Confidence interval for population mean : (13.046, 22.15)
Let be the sample mean.
We need to write the confidence interval in "less than" format.
less than sign → <
Confidence interval in "less than" format will be:
