Answer:
Maximum area possible
f(max) = 3906,25 ft²
Dimensions:
a = 62,5 ft
w = 62,5 ft
Step-by-step explanation:
Perimeter of the rectangular fencing P = 250 feet
And sides of the rectangle a and w (width of rectangle)
Then
A = a*w
2a + 2w = 250 ⇒ a = (250 -2w)/ 2 ⇒ a = 125 - w
f(w) = (125 - w ) *w f(w) = 125w - w²
Taking derivatives both sides of the equation
f´(w) = 125 - 2w f´(w) = 0 125 - 2w = 0
w = 125/2
w = 62,5 ft ⇒ a = 125 - 62,5
a = 62,5 ft
f(max) = ( 62,5)²
f(max) = 3906,25 ft²
Answer:
C. (0.17, 0.39)
Step-by-step explanation:
Range of possible values that best describes an estimate for the population parameter is given by the formula;
p^ ± z(SE)
Now, we are given sample proportion is 0.28. Thus, p^ = 0.28
The range will have to be same difference to the left of 0.28 as it is to the right of 0.28.
For option A; difference between 0.14 and 0.28 which is 0.16 is not the same difference between 0.36 and 0.28 which is 0.08. Thus it's not correct.
For option B: difference between 0.16 and 0.28 which is 0.12 is not the same difference between 0.38 and 0.28 which is 0.10 Thus it's not correct.
For option C: difference between 0.17 and 0.28 which is 0.11 is the same difference between 0.39 and 0.28 which is also 0.11. Thus it's correct.
Foe option D: difference between 0.15 and 0.28 which is 0.13 is not the same difference between 0.37 and 0.28 which is 0.09 Thus it's not correct.
The probability of drawing a green marble will be found as follows:
1. First, find your total number of outcomes by adding together all of the types of marbles to find the total you might draw from the bag so that you may make this a proportion. Now, you get your type of marble you want to know the probability of, and you put the total number of green marbles over this number. The total number of possibilities is 50, and the number of green marbles is 16.
2. I'm not sure what type of answer you are looking for, but the following answers could be the following:
- 16/50
- 32%
-.32
Hope this helps.
