Answer:
And based on this the best answer would be:
a. mean = 4; standard deviation = 2.68
Step-by-step explanation:
For this case we have the following data given:
1,5,8,5,1
We can find the sample mean with the following formula:
And replacing we got:
And for the deviation (assuming that the correct approximation is the deviation for a population) we can calculate the deviation with the following formula:
And replacing we got:
And based on this the best answer would be:
a. mean = 4; standard deviation = 2.68
Find the area and perimeter of the following triangle with the given vertices:
(1, 2), (8, 2) and (3, 6)

Ok so 65 percent of 10,000 is 6500. This means that she has to get the other 3500 herself. Since she has a year to save divide 3500 by 12 for each month of the year which is equal to $291.67. Then simply round up to get your answer which is A. $292.
Hope this helped and good luck
J is your andswer. Area is side x side so multiply
Complete question is;
Leslie is a biologist. She is going to randomly select one animal from her lab to study. There are 5 salamanders, 3 crayfish, and 12 minnows in her lab. What is P(salamanders).
Answer:
P(salamanders) = 0.25
Step-by-step explanation:
We are given;
number of salamanders = 5
number of crayfish = 3
number of minnows = 12
total number of animals; n = 5 + 3 + 12 = 20 animals
Now, we want to find out the probability that the animal Leslie randomly selected is a Salamander.
Thus,
P(salamander) = number of salamanders/total number of animals
P(salamander) = 5/20
P(salamander) = ¼ = 0.25
