Answer: $x_1=2\\\\x_2=-\frac{1}{2}$

Step-by-step explanation:

To find the zeros of the quadratic equation given in the exercise, you need to apply the proccedure shown below:

- You must rewrite it as following:

$6x^2-9x-6=0$

-You can apply the Quadratic formula, which is shown below:

$x=\frac{-b\±\sqrt{b^2-4c}}{2a}$

In this case:

$a=6\\b=-9\\c=-6$

- Therefore, when you substitute values, you obtain:

$x=\frac{-(-9)\±\sqrt{(-9)^2-4(6)(-6)}}{2(6)}$

$x_1=2\\\\x_2=-\frac{1}{2}$

a random sample of size 200 is drawn from a large population. The population standard deviation is 1.2. The sample mean is 15.8.

Marrrta [24]

Step-by-step Answer:

N=sample size = 200

sigma = population standard deviation = 1.2

s=Sample mean = 15.8

Best estimate of population mean = 15.8

standard error = sigma / sqrt(N)

= 1.2/sqrt(200)

= 0.08485

Therefore

estimate of population mean = 15.8 +/- 0.0848
