In a wildlife preserve, a random sample of the population of 150 raccoons was caught and weighed. The results, given in pounds, were 16, 18, 18, 24, 25, 27, 28, 31, 31, and 32. Jean made the qualitative statement, "The average weight of the raccoon population is 26 pounds." Is her statement reasonable? Complete the explanation.
Jean's statement (select) reasonable because the median value of the data is pounds.
Answers
Answer:
The average is 24 so her answer is reasonable cause it is not too far off.
Step-by-step explanation:
Average = sum/count
(16 + 18 + 18 + 24 + 25 + 27 + 28 + 31 + 31 + 32)/10
240/10
24
24 is close to 26

What is the surface area of the triangular prism below?
Answers
Answer:
Let me figure it out rq hold on
how to find the surface area:
The surface area of the triangular prism is the sum total of the areas of its bases and its lateral faces,
We have 2 triangles to add and 3 rectangles.
Area of a rectangle is length x width.
Area of a triangle is 1/2 x base x height.
The top 2 rectangular sides are 20 x 10 = 200 each = 400 total.
The bottom rectangle is 20 x 12 = 240
The triangles are each 1/2 x 12 x 8 = 48, and there are 2 triangles, = 96
Add them all up: 400 + 240 + 96 = 736 square feet

Step-by-step explanation/ Answers
because you have 5% possibilities and a total of 100%. You divide
100 by 5 and then you get 20 so that is for question 5
for question 6 it would be 80 because 100 - 20 is 80
for question 7 it will be 40 because 20 + 20 is 40

4m^2 - 14m - 14m + 49
4m^2 - 28m + 49
Answer: 4m²-28m+49
Step-by-step explanation:
(2m-7)² can be written as (2m-7)(2m-7).
You would have to multiply it out like this:
2m times 2m=4m² (2x2=4 and mxm=m²)
2m times -7=-14m (2x-7=-14 then put a m on it)
-7 times 2m=-14m
-7 times -7=49
The equation would then look like this:
4m²-14m-14m+49
Then you would have to collect like terms. Like terms are terms with the same variables and powers. It will then look like this:
4m²-28m+49

Two lines, A and B, are represented by equations given below: Line A: y = x − 4 Line B: y = 3x + 4 Which of the following shows the solution to the system of equations and explains why? (1 point) a (−3, −5), because the point satisfies one of the equations b (−3, −5), because the point lies between the two axes c (−4, −8), because the point satisfies both equations d (−4, −8), because the point does not lie on any axis
Answers
Answer:
The answer is "C"
Step-by-step explanation:
Answer:
Answer C. This point lies between the two axes and its coordinates satisfy both equations
Step-by-step explanation:
Line A: y = x − 4
Line B: y = 3x + 4
Let's actually solve this system, using substitution: Equate
Line A: y = x − 4 to Line B: y = 3x + 4, obtaining:
x − 4 = 3x + 4
Subtract (x - 4) from both sides. Doing so yields
0 = 2x + 8, and so x = -4.
From Line A let's find y: Letting x = -4, we get: y = -4 - 4 = -8
and so the solution is (-4, -8). This matches Answer C. This point lies between the two axes and its coordinates satisfy both equations.
