The etimated answer would be 20. The method that I used is I rounded 3.9 to 4 and 4.6 to 5 and then I mutiplied. Hope I helped
The equation is
8x +7=125
Answer:
1. 1017.4
2. 1139.8
Step-by-step explanation:
Those the answers
The numbers are: 2n and (2n+2)
we can suggest this equation:
4(2n)=2(2n+2)-12
We compute this equation:
8n=4n+4-12
8n-4n=-8
4n=-8
n=-8/4
n=-2
we compute the numbers:
2n=2(-2)=-4
2n+2=-4+2=-2
answer: the numbers are -4 and -2.
Answer: 9 Apples
Step-by-step explanation:
Given the following :
Total number of bags = 12
Mean of the distribution(m) = 8
Number of apples (x):
6 - - - - 7 - - - - 8 - - - - 9 - - - - 10
Frequency (f) :
1 - - - - 4 - - - - 2 - - - - 3 - - - - 1
Therefore :
Let number of apples in the 12th bag = y
Frequency of 12th bag : (12 - 11) = 1
Mean of distribution(m) :
Sum of ( f * x) / sum of f
Sum of (f * x) = (6*1)+(7*4)+(8*2)+(9*3)+(10*1)+(y*1)
Sum of (f * x) = (6+28+16+27+10+y) = 87 + y
Sum of f = 12
From :
m = Sum of ( f * x) / sum of f
8 = (87 + y) / 12
87 + y = 12 * 8
87 + y = 96
y = 96 - 87
y = 9
Number of apples in 12th bag is 9 apples
