Answer:
bag 3
Step-by-step explanation:
Let's call the labels "green", "red", and "mix".
Pick mix for two reasons :
- First, it's not mixed so whatever color you pick is the color of the pair.
- Also, if you pick from either of the other two, you can't know if it's a mixed bag or not.
So, let's pretend you pick a red out. Move the label red to the bag. This must be true - cannot be a mix.
Now, you have the mix label <u>in your hand</u>, <u>one bag with a label</u> (green), and <u>one bag without a label</u> (previously red).
Since all bags mislabeled to begin, move the green label to the <u>blank bag</u> - since this label must be wrong.
Put the mix label on the <u>remaining bag</u>.
Answer:
D) x=
Step-by-step explanation:
The quadratic formula is :
A in terms of this question=9
B in terms of the question is 12
C in terms of the question is -24.
This question is an example of a quadratic equation. To work this out you may first need a calculator. The first step is to substitute the values of a,b and c into the formula. So once substituted the formula of becomes . Although when written in a calculator there will not be a plus and minus button and so you would have to do this separately.
However when substituting the values it would be best practice to put them in brackets.
1) Substitute the values into the equation for +.
2) Substitute the values into the equation for -.
It means the figure is 1/4 the size of the original figure
Answer
Explanation
We've been told to pick the function that best models the data in the table.
Given that x = time (hours)
y = Cost (dollars)
The best approach is to examine each of the options to pick which one matches the data in the table
Option A
y = 65.75x + 50
when x = 1
y = 65.75 (1) + 50
= 65.75 + 50
= 115.75
when x = 4
y = 65.75 (4) + 50
= 263 + 50
= 313
when x = 8
y = 65.75 (8) + 50
= 526 + 50
= 576
when x = 12
y = 65.75 (12) + 50
= 789 + 50
= 839
Option A matches the data perfectly.
Option B
y = 50x + 115.75
when x = 1
y = 50 (1) + 115.75
y = 50 + 115.75
y = 165.75
Since this first attempt for the second function doesn't match the data in the table, we can easily write this option off as a wrong answer.
Option C
y = 65.75x + 1
when x = 1
y = 65.75 (1) + 1
= 65.75 + 1
= 66.75
Since this first attempt for the third function doesn't match the data in the table, we can easily write this option too off as a wrong answer.
