27.5
22= K(8)
Divide 8 on both sides to get your K value
2.75 = K
Plug your K value into the other equation
Y= 2.75(10)
Solve to get Y
Y= 27.5
When the problem asks "vary directly", it is saying that you are multiplying your K value with your X value(K*X). If the problem is asks "vary indirectly", it is saying that you are dividing your K value by your X value (K/X)
Answer:
look below ⏬
Step-by-step explanation:
you can see there is a pattern
0.40
0.70
1.00
so you keep adding three (30)
1.30
1.60
1.90
And for 0
0.10
All in oder now
0- 0.10
10- 0.70
20- 1.00
30- 1.30
40- 1.60
50- 1.90
60- 2.20
D ( AC ) = 6 ( because A and C have the same y-coordinate )
d ( AB ) = √[(x2 - x1)² + (y2 - y1)²],
where A ( x1, y1 ) = ( -3, 1 ) and B ( x2, y2 ) = ( -1, 3 )
d ( AB ) = √[(-1 -(-3))² + (3 - 1 )²] = √[(-2)² + 2²] = √8 = 2√2
d ( BC ) = √[(3-(-1))² + (1-3)² =√[4² + (-2)²]= √20 = 2√5
The perimeter of ΔABC:
6 + 2√2 + 2√5 = 6 + 2 · 1.41 + 2 · 2.24 =
= 6 + 2.82 + 4.48 = 13.30
Answer:
Step-by-step explanation:
It's too bad about this problem. It's a fair game if you get paid the same amount that you have to pay if you lose.
You win 2 ways
- H - H
- T - T
- Probability 1/2
You lose 2 ways.
- H - T
- T - H
- Probability 1/2
Expectation
E = 1/2 * 3 - 1/2 * 4
E = 1.5 - 2
E = -0.5
Which means that you should expect to lose 0.5 dollars every time you play this dreadful game.
