<span>The
question here is why using either compatible numbers or rounding as a method
for estimation would be the same?
Well, we use rounding as a method of estimation to get a solution in a certain
equation faster yet the same.
For example, in the given equation we have 32 x 695
=> Instead of 32, we can use 30
=> instead of 695, we can use 700
=> 30 x 700
=> the answer is 21 000
Now, let’s multiply the exact number
=> 32 * 695
=> 22 240
Not, really exact yet close.
That’s how estimation works.

Answer:
55
Step-by-step explanation:
m angle A and m angle C are equal sine two of those sides are equal. You would do 3x + 40 = x +50
You subtract x, leaving it to be 2x + 40 = 50
Subtract the 40, leaving it be 2x = 10
Divide both sides by 2, which leaves x = 5
and then you would do 3(5) + 40, which is 55
Answer:
The range of the random variable is {0, 1, 2}.
Step-by-step explanation:
The bag contains red and blue marbles.
The experiments consists of two draws, with reposition.
The random variable assigns the number of blue marbles to each outcome.
If we have only two draws, we can only get 0, 1 or 2 blue marbles.
The range of the random variable is {0, 1, 2}.
