Step-by-step explanation:

$8x {}^{2} + 7x + 1 = 0 \\ d = 49 - 32 = 1 \\ x1 = \frac{ - 7 - \sqrt{17} }{16} \\ x2 = \frac{ - 7 + \sqrt{17} }{16}$

Based on the z-statistic of –2.5 for the sample data, should the null hypothesis be rejected? Yes, because the z-statistic lies

ivann1987 [24]

Answer:

No, because z-statistics lies within the critical region.

Step-by-step explanation:

The z value is calculated to determine whether the null hypothesis should be accepted or rejected. The null hypothesis is rejected when the z-value lies outside the critical region. The critical region is determined by the sample data.

a cone and a sphere have the same volume. the height of the cone is 96 units. what would be the values for the radius of the con

jolli1 [7]

The volume $V_c$ of a cone with base radius $r_c$ and height $h_c$ is

$V_c = \dfrac{1}{3}\pi r_c^2 h_c$

Similarly, the volume $V_s$ of a sphere with radius $r_s$ is

$V_s = \dfrac{4}{3}\pi r_s^3$

We know that $V_c=V_s$ and that $h_c=96$

So, we can set up the following equation:

$\dfrac{96}{3}\pi r_c^2=\dfrac{4}{3}\pi r_s^3$

We can simplify the common denominator 3, and pi appearing on both sides:

$96r_c^2=4r_s^3$

We can divide both sides by 4:

$24r_c^2=r_s^3$

Without further information, this is all we can say: the cubed radius of the sphere is the same as 24 times the squared radius of the cone.
