Indira reacts that the actual difference of 19-7.82 will be greater than the estimate of 19-8=11.Is Indira correct?Explain how Indira might have arrived at the prediction without subtracting the actual numbers.
Why the hell are you not going to just say the whole answer?
subtracting a smaller number results in a greater difference.
Indira is correct (all you really have to do is add 19 and 7.82 and it's pretty simple to do the second part! I don't want to say the full answer so you can figure it out but I'll get you on a head start!) Hope this helps
To determine if Indira's prediction is correct, let's first calculate the actual difference between 19 and 7.82.
Actual difference = 19 - 7.82
Actual difference = 11.18
Now, let's consider how Indira might have arrived at the prediction without directly subtracting the actual numbers.
One possible way is by using rounding or estimation techniques. Here's a step-by-step explanation of this process:
1. Indira rounded 19 down to the nearest whole number, which is 19.
2. Indira rounded 8 down to the nearest whole number, which is 8.
3. Indira subtracted the rounded numbers: 19 - 8 = 11.
By using this estimation method, Indira predicted that the actual difference would be 11.
To determine if Indira's prediction is correct, we can compare it with the actual difference we calculated earlier (11.18). Since 11.18 is greater than 11, we can conclude that Indira's prediction was incorrect.
In this case, using estimation techniques resulted in a less accurate prediction compared to directly subtracting the actual numbers.
