if 1 can has 3 tennis balls, then

n cans will have 3n (n*3) tennis balls.

thus, 3n= 27 (equation)

n=27/3

n=9

2) let the initial temp. be y

y - 5° F = 37 ° F

3) average speed= total distance/ total time

Solve the following quadratic by<br> completing the square.<br> y = x2 - 6x + 7
kobusy [5.1K]

Answer:

x = 5  or   x = 1

Step-by-step explanation:

 x² - 6x + 7 = 0

x² - 6x = -7

x² - 6x + 9 = -7 + 9      1/2 of the x term than square it and add it the both sides.

(x - 3)(x - 3) = 2

( x -3)² = 2

\sqrt{(x - 3)^2 = \sqrt{2}

(x -  3) = ± 2

x - 3 = 2  or  x - 3 = -2

x = 5     or  x = 1

How do I construct a sample data set for which n=7, x=9(x bar), and s=0?
JulijaS [17]
When the standard deviation = 0, there is no deviation at all. So the numbers are all the same. And there are seven of them. And the average is nine. 
So the sample data set would just be seven 9s.
