Joint Frequency because of the fact that it "joins" one number from the column(up and down) and one from the row(side-by-side), hence the two-way table.
Answer:
BC = 2
Step-by-step explanation:
We first need to use triangle BAD to find BD,
BD is the hypotenuse, so use pythagorean theorem...
(√23)² + (√13)² = (BD)²
23 + 13 = (BD)²
36 = (BD)²
6 = BD
Now BD is the hypotenuse of triangle BCD, so use pythagorean theorem agian to find BC
(4√2)² + (BC)² = 6²
32 + (BC)² = 36
(BC)² = 4
BC = 2
Answer:
12,000,000
Step-by-step explanation:
33 part a is h=30 so a=15 and I think it would be 121 cm2 for the area
33 part b is just the first base which is 12
33 part c is 176.4 is the length
Answer:
See Below.
Step-by-step explanation:
Remember that:
- If c² > a² + b², then we have an obtuse triangle.
- If c² < a² + b², then we have an acute triangle.
- And if c² = a² + b², then we have a right triangle.
Where c is the longest side, and a and b are the two remaining sides.
(16 is less than 9 + 9 or 18.)
(25 is equal to 9 + 16 = 25.)
