Answer:
D. 27
Step-by-step explanation:
If you plug in the variable and solve it is equal on both sides. EX.
1. 27/3 -3 = 27/9 +3
2. 9-3 = 3+3
3. 6 = 6
Answer:
<u><em>The answer will vary depending on what table you were given.</em></u>
<u><em></em></u>
Step-by-step explanation:
I'm pretty sure you were given a table along with this question. I do not have this table, so I'm going to create my own. Before I do, I'll explain the function if that's what you're wondering.
Function: y = -3x
This function means you multiply -3 by x to get y.
An example of this is x = 6. To find y, we multiply -3 by 6; y = -18 in this example.
Now, I'll make a small chart with x going from 0 to 5.
| X | Y |
| 0 | 0 |
| 1 | -3 |
| 2 | -6 |
| 3 | -9 |
| 4 | 12 |
| 5 | -15 |

Answer:
1509
Step-by-step explanation:
We know that, formula for number of samples is,

When nothing is given, we take
and we know that
.
SE = 0.03 (the true proportion should remain withing 3%)
Putting the values we get,


Therefore, the sample required to estimate the true proportion to within 3 percentage points is 1509.
The number of chicken wings that Mohal can buy is 12.
<h3>How to calculate the cost?</h3>
It should be noted that Mohal bought 20 chicken wings for $50.00. The cost of each wing will be:
= Total amount / Number of chicken wings
= $50 / 20
= $2.50
When he spent $30.00, the number of wings will be:
= Amount / Cost per wing
= $30 / $2.50
= 12
There will be 12 chicken wings. This illustrates the proportion.

So...
= (5x-12) - (3x+18)
= 5x - 12 - 3x - 18
= 2x - 30
I believe that's the answer
