Answer:
The least possible number of people in the family is 8.
Step-by-step explanation:
To determine the minimum number of people that make up the family, knowing that 0.83 of the children are boys, the following logical reasoning must be carried out:
Given that 0.83 is the result of 5/6, it can be said that 5 of the 6 children of the couple are boys. These 6 children must be added to the 2 fathers of the family, with which the total number of family members is 8.
Example: In a survey of women in a certain country (ages 20-29) the mean height 63.7 inches with a standard deviations 2.65 inches. What is the height that represent 85 perentile ? what is the height represent First quartile
answer: in a survey of women in a certain country (ages 20-29) the mean height 63.7 inches with a standard deviations 2.65 inches.
What is the height that represent 85 percentile ?
Find the z-value of the 85th percentile::
invNorm(0.85) = 1.0364
Find the corresponding height value::
h = z*s + u
h = 1.0364*2.65 + 63.7
h = 66.47"
We need to compute for the length of each trophy given that one trophy is 5 inches wider than the other.
Let x be the length of the first trophy.
Let x+5 be the length of the second trophy
The solution is shown below:
x + (x + 5) = 17
x + x + 5 =17
2x =17 -5
2x = 12
x = 12/2
x=6 (for the first trophy)
x + 5 = 6+5 = 11 (for the second trophy)
The first trophy is 6 inches wide while the second trophy is 11 inches wide.
