Answer:

A. Probability of Russell = 12/37 or 32.4% (Rounding to the next tenth)

B. Probability of Peter = 5/74 or 6.8% (Rounding to the next tenth)

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Guard Forward Center Totals

Over 6 feet 25 30 30 85

Under 6 feet 130 120 35 285

Totals 155 150 65 370

2. Russell is 5'9". What is the probability he is a forward?

Probability = Number of forwards under 6 feet/Total number of players

Probability = 120/370

Probability = 12/37 or 32.4% (Rounding to the next tenth)

3. Peter is 6'2". What is the probability he is a guard?

Probability = Number of guards over 6 feet/Total number of players

Probability = 25/370

Probability = 5/74 or 6.8% (Rounding to the next tenth)

Answer:

$P(X$ $0.9619$

Step-by-step explanation:

From the given information;

the probability of getting returned p = 0.1

If eight rings are sold today, what is the probability that fewer than three will be returned;

According to binomial distribution

Binomial distribution is the probability of success or failure of an outcome of an experiment under observation which is usually repeated several trials. Binomial experiments are random experiment with fixed number of repeated experiment. If we cannot predict before head, the outcome of an experiment , the experiment is called a random experiment.

So , using binomial distribution to determine the probability that fewer than three will be returned;

i.e

$P(X$ $\sum_{x=0}^{2}\binom{8}{x}(0.1)^{x}(1-0.1)^{8-x}$

$P(X$ $0.9619$

Why might the triangulation method not always produce an exact point (other than any measurement errors)

Rufina [12.5K]

Answer:

The triangulation method might not always produce an exact point (other than any measurement errors) because:

The method uses different data sources, researchers, and theories or perspectives.

Step-by-step explanation:

Research Triangulation uses multiple methods, data sources, different investigators, and varied theories for the purpose of developing a more comprehensive understanding of the underlying situations. Triangulation validates the qualitative research by obtaining information from different sources, investigators, viewpoints, or methods.

JulijaS [17]

Answer:

The turtle population's rate of growth will be 32 turtles per year after 2 years and 248 per year after 6 years.

Ten years after the conservation measures are implemented the population will be 3260 turtles.

Step-by-step explanation:

To find the rate of growth of the turtle population at any time t you need to find $N'(t)$

$\frac{d}{dt}N(t)=\frac{d}{dt}(2t^3+3t^2-4t+1000)\\\\\mathrm{Apply\:the\:Sum/Difference\:Rule}:\quad \left(f\pm g\right)'=f\:'\pm g'\\\\\frac{d}{dt}(2t^3)+\frac{d}{dt}(3t^2)-\frac{d}{dt}(4t)+\frac{d}{dt}(1000)\\\\\mathrm{Apply\:the\:Power\:Rule}:\quad \frac{d}{dx}\left(x^a\right)=a\cdot x^{a-1}\\\\N'(t)=6t^2+6t-4$
