which shows the correct substitution of the values a, b, and c from the equation 0 = 4x2 2x – 1 into the quadratic formula below

irinina [24]

$0 = 4x^2+2x- 1$

Quadratic formula is

$x = \frac{-b+-\sqrt{b^2-4ac}}{2a}$

'a' is the coefficient of x^2 = 4

'b' is the coefficient of x = 2

'c' is the constant = -1

Now we plug in all the values in quadratic formula

$x = \frac{-b+-\sqrt{b^2-4ac}}{2a}$

$x = \frac{-2+-\sqrt{2^2-4(4)(-1)}}{2(4)}$

$x = \frac{-2+-\sqrt{18}}{8}$

The above one is the substitution of values of a,b,c in quadratic formula.

45.50 + 11.375 = 56.875

and that rounds to 56.88

for option 2 I recommend a calculater

The results for all 10 grocery surveys were actually generated using a mathematical simulation, found on the Simulation tab of t

Debora [2.8K]

The standard error of the mean is given by:

$\frac{\sigma}{\sqrt[]{n}}$

where sigma is the standard deviation and n is the sample size. In this case the sample size is 10 and the standard deviation is 0.657, then the standard error is:

$\frac{0.657}{\sqrt[]{10}}=0.208$

Therefore the standard error is $0.208.
