A line that includes the points ( 0, z ) and ( 1, 7 ) has a slope of 9. What is the value of z ? z =

I am Lyosha [343]

Slope = change in y / change in x
9 = (7-z) / (1-0)
9/1 = (7-z) / 1
9 = 7 - z
-7. -7
2 = -z so -2 = z

If the sum of squares for a sample containing 51 items equals 200, what is the standard deviation?

Mashcka [7]

The standard deviation is 1.98. Option A is correct.

The standard deviation formula is given as

$\sigma = \sqrt{\frac{SS}{n} }$

where:

SS is the sum of squares = 200
n is the sample size = 51

Substitute the given parameters into the formula to have:

$\sigma = \sqrt{\frac{200}{51} }\\\sigma = \sqrt{3.922}\\\sigma = 1.980$

Hence the standard deviation is 1.98

6a² + 7ax - 3x²
6a² + 9ax - 2ax - 3x²
3a(2a) + 3a(3x) - x(2a) - x(3x)
3a(2a + 3x) - x(2a + 3x)
(3a - x)(2a + 3x)
