length is nine inches less than twice width. L = 2W - 9
perimeter is 84 inches 2L +2W = 84
Substitute the expression for L (2W-9) for L in the second equation resulting in the follwing
2(2W-9) + 2W = 84
4W - 18 + 2W = 84
(4W+2W) = 84+18
6W = 102
W = 102/6 = 51/3
L = 2(51/3) - 9
= L= 17-9
L=6
Answer:
Choice C
Step-by-step explanation:
A and B represent symmetric distributions, that is most data values lie in the middle and the both tails are equally longer.
C represents a positively skewed distribution, most of the data values lie to the left with a few points skewing the shape of the distribution to the right.
Answer:
29
Step-by-step explanation:
Let Jiri's age be 'x'. Pamela's age is 3x since Pamela's age is three times Jiri's age.
The sum of their ages is 116:
x + 3x = 116
4x = 116
x = 116 ÷ 4 = 29
x = 29
Jiri's age is 29
Answer:
The number of Girls players in the Team of 18 players is 6 .
Step-by-step explanation:
Given as :
The total number of player including boys and girls = 18
And 
times girls player + 
times boys player = 7
Let The number of boys player = B
The number of girls player = G
So, According to question
G + B = 18 ...1
× G + × B= 7
or, 
+ 
= 7 ...2
or, Put the value of B from eq 1
or, + 
= 7
Or, - 
+ 6 = 7
or, 
= 7 - 6
Or, 
= 1
∴ G = 1 × 6 = 6
Hence The number of Girls players in the Team of 18 players is 6 . Answer
