Leslie is a biologist. She is going to randomly select one animal from her lab to study. There are 555 salamanders, 333 crayfish, and 121212 minnows in her lab.
What is \text{P(salamander})P(salamander)start text, P, left parenthesis, s, a, l, a, m, a, n, d, e, r, end text, right parenthesis?
If necessary, round your answer to 222 decimal places.
Answers
Answer:
1/4
Step-by-step explanation:
Given
amount of salamanders, = 5
amount of crayfish = 3
amount of minnows = 12
Total fish = Total outcome = 5+3+12
Total outcome = 20
Since we are looking for the probability of selecting salamanders, our expected outcome will be 5.
Probability = expected outcome/total outcome
Pr( salamanders,) = 5/20
Pr( salamanders) = 1/4
Hence the probability of selecting salamanders, is 1/4
Hope this helps and best of luck!!

The owner of a sporting goods store gathered data about the numbers of men's, women's and children's bicycles sold each month. She used a
graphing tool to organize the data in different scatter plots and found these lines of best fit:
Answers
Answer:
The answer A
Step-by-step explanation:
The average correlation is close to The relationship between the number of men's, x and the number of women's, y bikes sold hence, it is a line of best fit so, option A is correct.
What is a line of fit?A straight line that minimizes the gap between it and some data is called a line of best fit. In a scatter plot containing various data points, a relationship is expressed using the line of best fit.
Given:
The owner of a sporting goods store gathered data about the numbers of men's, women's, and children's bicycles sold each month,
The relationship between the number of men's, x and the number of women's, y bikes sold is molded by the equation, y = 0.95x + 0.83, and the correlation coefficient is 0.791,
The relationship between the number of men's, x, and the number of children, y bikes sold is molded by the equation, y = 0.87x + 0.98, and the correlation coefficient is 0.564,
The relationship between the number of children x and the number of women's bikes sold is molded by the equation, y = 0.73x + 0.91, and the correlation coefficient is 0.945,
As you can see that the average of the correlation coefficient is,
Average = 0.791 + 0.564 + 0.945 / 3
Average = 2.3 / 3
Average = 0.77
Thus, the correlation 0.791 is the line of best fit.

Explanation: The dimensions of Ellie's boxes in meters are: 0.45m by 0.40m by 0.35 ( to convert from centimeters to meters we just divide by 100, because 1m =100cm). therefore the volume of each box is 0.063 m3
Now the dimensions of the empty van are 3.6m by 1.6m by 2.1 m, therefore its volume is: 12.096 m3
So the amount of boxes that Ellie can put in the van is equal to the volume of the van divided by the volume of each box: 192 boxes
So 192 boxes can be put into the van.
Now Ellie can put 3 boxes in the van in 1 minute, therefore the amount of time it will take her to put 192 boxes into the van will be: 64 minutes
So it takes Ellie 64 minutes to put as many boxes into the van as she can.
