The proportion of students that got the recommended amount of sleep is 0.179.

<h3>What is a proportion?</h3>

A proportion can be defined as an expression which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.

<h3>How to calculate proportion of students that got the recommended amount of sleep?</h3>

Since the total number of students in this class is 28, we would develop an expression to relate the number of students that sleep at least for 5 hours per night:

Proportion = 5/28

Proportion = 0.179.

Particle x moves along the positive x-axis so that its position at time t ~ 0 is given by x(t) = 5t 3 - 9t 2 + 7. at what time t

Arada [10]

Answer: 1.2 seconds

Explanation:

$At the farthest point the velocity of particle will be zero. \ Differentiating the given equation of position and equating it with zero:$$\begin{aligned}x(t) &=5 t^{3}-9 t^{2}+7 \\x^{\prime}(t) &=15 t^{2}-18 t \\0 &=15 t^{2}-18 t \\t(15 t-18) &=0 \\t &=0 \\t &=\frac{18}{15}=1.2 \mathrm{~s}\end{aligned}$

$$$Thus, at $t=1.2 \mathrm{~s}$ particle will be at the farthest point. \\\\\underline{Justification:}\\The particle moves towards the left from $t \in[0,1.2)$. After that particle keeps moving in the positive x-direction.$

Nana76 [90]

Answer:

Drive reduction theory is the idea that a phycological need creates an aroused state that drives the organism to reduce the need by doing the desired act. homeostasis is the physiological aim of drive reduction, homeostasis is the maintenance of a steady internal state. Incentives are positive or negative stimuli that lure or repel us from reducing drives. Optimal arousal theory says that some motivational behaviors actually increase arousal. last of all, Maslow's hierarchy of needs, a pyramid diagram showing our needs on each level, going from physiological to self transcendence.

Nina [5.8K]

Group of answer choices.

A. Ahmed, who studied mathematics and economics.

B. Michelle, who studied psychology and physiology.

C. Marisol, who studied communications and business.

D. Jackson, who studied liberal arts and foreign languages.

Answer:

C. Marisol, who studied communications and business

Explanation:

Human resources (HR) can be defined as an art of managing, controlling and improving the number of people (employees or workers), functions, activities which are being used effectively and efficiently by an organization. Thus, human resources managers are saddled with the responsibility of managing and improving the welfare and working conditions of the employees working in an organization.

In this scenario, Marta is interviewing candidates for a position in the Human Resources department at her company. She is deciding who to interview by going through resumés and looking at the subject areas in which each candidate studied.

Hence, the candidate that would be the best choice for Marta to interview is Marisol, who studied communications and business because with her course of study, she should have the requisite knowledge and skill set to work effectively and efficiently in the Human Resources department.
