If balls were drawn from X to the other X, that how you find yo answer
Answer:
Tallahassee's Range: 6
Key West's Range: 4
Step-by-step explanation:
To calculate range, you'd subtract the lowest value from the highest value
Tallahassee:
Highest Value: 90
Lowest Value: 84
Range: 90 - 84 = 6
Key West:
Highest Value: 87
Lowest Value: 83
Range: 87 - 83 = 4
Answer: A. (3,-2)
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable x
[2] 4x = 5y + 22
[2] x = 5y/4 + 11/2
// Plug this in for variable x in equation [1]
[1] 2•(5y/4+11/2) + 5y = -4
[1] 15y/2 = -15
[1] 15y = -30
// Solve equation [1] for the variable y
[1] 15y = - 30
[1] y = - 2
// By now we know this much :
x = 5y/4+11/2
y = -2
// Use the y value to solve for x
x = (5/4)(-2)+11/2 = 3
Solution :
{x,y} = {3,-2}
Answer:
1) If the order doesn't matter, there are 36 possible outcomes.
2) If the order does matter, there are 181,440 possible outcomes.
Step-by-step explanation:
1) In the case when the order doesn't matter , we have to calculate a combination of 7 screws in 9 holes.
We use the formula for combinations:
being r: the number of screws and n: the number of holes.
2) When the order does matter, the possible outcomes are called permutations. We have permutations of 7 screws in 9 holes.
We use the formula for permutations:
Answer:
x=4
Step-by-step explanation:
2(8 - 12x) + 8x = -25x + 52
Distribute
16 -24x +8x = -25x +52
Combine like terms
16 - 16x = -25x +52
Add 25x to each side
16 -16x+25x = -25x+52+25x
16+9x = 52
Subtract 16 from each side
16+9x-16 = 52-16
9x = 36
Divide by 9
9x/9 = 36/9
x =4
