Researchers in plant growth are investigating the proportions of seedlings that sprout under two environmental settings in a lab experiment. Let pˆC represent the sample proportion of seedlings that sprout in garden C, and let pˆH represent the sample proportion of seedlings that sprout in garden H. For random samples of 100 garden C seedlings and 100 garden H seedlings, the sampling distribution of the difference between sample proportions pˆC−pˆH has σpˆC−pˆH≈0.051. Which of the following is the best interpretation of σPˆC−PˆH≈0.051 ?
Answer:
E
Step-by-step explanation:
For all random samples of 100 garden C seedlings and 100 garden H seedlings, the average distance of all possible differences between sample proportions pˆC−pˆH from the mean of the sampling distribution is approximately 0.051.

Find the total surface area
Answer:
47
Step-by-step explanation:
9+9+9+9+7+7
forgive me if i am wrong
Answer:
147 cm^2
Step-by-step explanation:
To find the surface area, you would have to add up the area of all shapes:
Area of triangle: 1/2 base*height
Area of square: length*width
----------
square = l*w = 7*7 = 49 cm^2
----------
So since there are 4 triangles, you would have to multiply the result by 4.
triangle = 1/2 7*9 = 49/2 = 24.5
4 triangles = area of 1 triangle * 4 = 4(24.5) = 98 cm^2
----------
add them up, and you get 49 + 98 = 147 cm^2

Justin is evaluating the expression 12.5 + 3.8 x, when x is 7.9. 12.5 + 3.8 (7.9). 16.3 (7.9). 128.77. What was Justin's error? Justin should have multiplied 12.5 and 7.9 first. Justin should have added 12.5 and 7.9 first. Justin should have multiplied 3.8 and 7.9 first. Justin should have added 3.8 and 7.9 first.
Answer: Justin should have multiplied 3.8 and 7.9 first.
Step-by-step explanation:
Given the equation
12.5 + 3.8x
where, x = 7.9, the first thing that Justin's should have done was to multiply 3.8 and 7.9 first. This will be:
= 12.5 + 3.8x.
= 12.5 + 3.8(7.9)
= 12.5 + 30.02
= 42.52
Answer: (C) Answer: Justin should have multiplied 3.8 and 7.9 first.
