The answer is W.E.B. Du Bois
The easiest way to do this is calculate the probability that all drives crash, and subtract that from one. The first one is .06 squared subtracted from 1, so it’s .9964 or 99.64%. The second one is .06 cubed subtracted from 1, so it’s .9998, or 99.98 %
The frame rate of a virtual reality (VR) headset indicates: the number of images displayed per second.
<h3>What is Virtual Reality (VR) headset?</h3>
A virtual reality (VR) headset refers to a head-mounted device which consist of two LCD displays (one per eye) that provides the wearer with a view of virtual physical environments (realities) and human-machine interactions through the use of various computer technologies.
<h3>What is frame rate?</h3>
Frame rate can be defined as a a measurement of the speed at which successive images are displayed per unit of time (second).
In this context, the frame rate of a virtual reality (VR) headset indicates the number of images that are displayed per second such as <u>24 fps</u>.

The given statement "dual innervation is the term used to describe an organ that receives both sympathetic and parasympathetic motor impulses" is TRUE.
<h3>
What is dual innervation?</h3>
Dual innervation refers to an organ's ability to receive both sympathetic and parasympathetic motor impulses. Sympathetic responses are extensive throughout the body, which is partially explained by the fact that a single sympathetic preganglionic fiber may synapse with 20 or more postganglionic fibers.
Examples of organs with dual innervation include the heart and the eye.
The parasympathetic system slows heart rate whereas the sympathetic system speeds it up.
While the parasympathetic system causes the pupil of the eye to constrict, the sympathetic system causes the pupil to enlarge.
The heart and lungs have separate innervations.
The vagus nerve's impact on the pacemaker cells of the heart has a tiny probability of affecting the rate and force of heart muscle contraction.
Therefore, the given statement "dual innervation is the term used to describe an organ that receives both sympathetic and parasympathetic motor impulses" is TRUE.

The value of kb of cyclohexane in the given question is; kb = 2.82 °C/m
<h3>Understanding Molality of a Solution</h3>
Molality of solution = (Number of moles of C₆H₄Cl₂)/(Mass of Cyclohexane)
Now;
Number of moles of C₆H₄Cl₂ = Mass/molar mass = 2g/147 g/mol
Number of moles of C₆H₄Cl₂ = 0.0136 mol
Molality of solution = 0.0136/(22.5 * 10⁻³ kg)
Molality of solution = 0.6 m
Now, to find kb for cyclohexane, we will use the formula;
T_b(solution) - T_b(solvent) = kb × molality of solution
Thus;
82.39 - 70 = kb * 0.6
kb = (82.39 - 70)/0.6
kb = 2.82 °C/m
