Given that a sample of 32 cowboys gave the following years of longevity:
58 52 68 86 72 66 97 89 84 91 91
92 66 68 87 86 73 61 70 75 72 73
85 84 90 57 77 76 84 93 58 47
The stem and leaf display for the data is given as follows:
4 | 7
5 | 2, 7, 8, 8
6 | 1, 6, 6, 8, 8
7 | 0, 2, 2, 3, 3, 5, 6, 7
8 | 4, 4, 4, 5, 6, 6, 7, 9
9 | 0, 1, 1, 2, 3, 7
Density of water = 1000 kg/m^3
1 m^3 = 1000 litres
Therefore,
1000 kg/1000 l => 1 kg/l => 1000 g/l
Then, 300 g of water = 300/1000 l = 0.3 l
The concentration of the syrup = mass/amount of water = 60 g/0.3 l = 200 g/l
Answer is C.) triangle 1 and triangle 3
triangle 1 and triangle 3 are congruent by SAS
1) x=
square root ({15}^{2} - {9}^{2} )
all the others are the same method, just remember
the horizontal line^2 + the vertical line ^2 is equals to the line opposite the right angle^2
