Answer:
A. No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means.
Step-by-step explanation:
No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means. The central limit theorem says that if we take a large sample (i.e., a sample of size n > 30) of any distribution with finite mean 
and standard deviation 
, then, the sample average is approximately normally distributed with mean and variance 
.
Answer: B is the answer
Step-by-step explanation:
Answer:
8m ×3.5m
Step-by-step explanation:
Area of rectangle= length ×width
Let the length and width of the rectangle be L and W meters respectively.
Area of rectangle= LW
LW= 28 -----(1)
L= 2W +1 -----(2)
Subst. (2) into (1):
(2W +1)(W)= 28
<em>Expand:</em>
2W² +W= 28
<em>-28 on both sides:</em>
2W² +W -28= 0
<em>Factorise</em><em>:</em>
(W +4)(2W -7)= 0
W +4=0 or 2W -7=0
W= -4 (reject) or W= 3.5
Substitute W= 3.5 into (2):
L= 2(3.5) +1
L= 7 +1
L= 8
∴ The dimensions of the rectangle is 8m ×3.5m.
Answer:
1/8
Step-by-step explanation:
assuming that the rest of what brad walked was sunny
7/8 - 6/8(3/4) = 1/8
Answer:
605/12 ft by 121/12 ft
Step-by-step explanation:
So, the dimensions of the dog run would be 5x as the length and x as the width.
The perimeter of this dog run would therefore be :
5x + 5x + x + x = 12x
From here, we know that 12x = 121 ft, so x = 121/12 ft
so the final dimensions of the dog run would be 605/12 ft by 121/12 ft
