Answer: The third option is correct
Step-by-step explanation: With increased trials, experimental probability will grow closer to theoretical probability. Blue pens make up 1/2 of the probability pool.
Answer:
I believe it is x+3..
Step-by-step explanation:
We will define the following variables to solve the problem:
x = amount of round trips from 10 tons truck
y = amount of round trips from 12 tons truck
We write the system of equations:
x + y = 20
10x + 12y = 226
The solution to the system of equations is:
x = 7
y = 13
Answer:
10 tons truck makes 7 round trips
12 tons truck makes 13 round trips
Answer:
a/(√b)(√2c)
Step-by-step explanation:
√(2a/3b) X √(6a/4c) = √(2a*6a)/√(3b*4c)
a/2√12/(√3b*2c) = 2a/2(√1/√b*2c
a/(√b)(√2c)
Plug in the points and see if they satisfy the equation.
y = 2x - 3
(1, -1)
-1 = 2(1) - 3
-1 = 2 - 3
-1 = -1
So (1, -1) satisfies the equation.
(-3, 0)
0 = 2(-3) - 3
0 = -6 - 3
0 = -9
So (-3, 0) does not satisfy the equation.
(5, 4)
4 = 2(5) - 3
4 = 10 - 3
4 = 7
So (5, 4) does not satisfy the equation.
Therefore your answer is the first one, (1, -1).
