Answer:

c. h+j+k over 3

Step-by-step explanation:

It is known that

\text{Average}=\frac{\text{Sum of observations}}{\text{Total number of observation}}

In this context, h, j, and k denote the melting points of helium, hydrogen, and neon respectively,

The total of the melting points can thus be expressed as h + j + k,

Given that there are 3 gases total,

So,

\text{Average melting points}=\frac{h+j+k}{3}

It follows that (h+j+k) over 3

⇒ Option c is therefore correct.

The average is also known as the mean, calculated as the sum of values divided by the total number of data points.

Values are h, j, and k

The total data count is 3

The sum of the values is represented as h + j + k

Thus, the mean is [h + j + k] / 3

=> Answer: option c. [h+j+k] over 3

A CD has a 5% chance of being a smash hit and profiting $5.2 million, a 50% chance of being a modest success and profiting $0.9
Zina [12379]

P(S) = Probability of Smash = 0.05 (5%)
P(M) = Probability of Modest = 0.5 (50%)
P(F) = Probability of Flop = 0.45 (45%)
Based on this, we utilize the model for discrete random variables, leading to:
E(X) = (0.05 * 5.2) + (0.5 * 0.9) + (0.45 * 0)
= 0.26 + 0.45 + 0
= 0.71 Mill'

Jackson is conducting an experiment for his Physics class. He attaches a weight to the bottom of a metal spring. He then pulls t
zzz [12365]
The behavior of the spring can be described using either a sine or cosine function. The spring's maximum displacement is 6 inches, occurring at t=0, which we will define as the positive peak. Therefore, we can express the function as:
6sin(at+B). The spring's period is 4 minutes, which means the time factor in the equation must complete a cycle (2π) in 4 minutes. This gives us the equation 4min*a=2π, leading to a=π/2. Generally, a=2π/T where a is the coefficient and T is the period. For B, since sin(π/2)=1, we determine B=π/2 because at t=0, the equation becomes 6sin(B)=6. Therefore, we substitute to form f(t)=6sin(πt/2+π/2)=6cos(πt/2)
due to trigonometric relations.
