E. none of the above because there the opposite because one is division and the other is multiplication hope it helps
If Jimmy wants to keep track of his checkbook balance he should pay attention to three things:
First, when Jimmy make deposits, he should add the amount of the deposits from the amount he has in the bank.
Second, when Jimmy write checks, he should <span>deduct the amount of the checks from the amount he has in the bank.
And third, he should also deduct any bank charges </span>from the amount he has in the bank.
From the question we know that Jimmy <span>made deposits of $20, $80, and $165, so he should add those amounts to the money he has in the bank:
</span>


We also know that he <span>wrote checks for $216.58, so he should subtract the amount from the balance:
</span>


<span>Last but not least, the bank charged Jimmy $3.50, so we should subtract that amount from the balance too:
</span>


<span>
Notice that you can also add/subtract all the deposits, checks, and bank charges all at once:
</span>


<span>
Either way we can conclude that</span><span> his ending balance for the month was
$502.48; therefore,
d is the correct answer.</span>
Answer:
Let's solve for x.
2x+3y=6
Step 1: Add -3y to both sides.
2x+3y+−3y=6+−3y
2x=−3y+6
Step 2: Divide both sides by 2.
2x

=
−3y+6

1) In this study, the control group is the first group of 310 subjects that were instructed to take only 600 mg daily of vitamin C. (Option C; that is, group 1).
2) The study is not Blind (Option C).
In an experimental setup to test a theory, A control group is the set of experimental participants that the theory to be tested isn't applied upon.
In the case of testing a new treatment, the control group is the group that the new treatment isn't administered.
For this question, the experiment was set up to test the effectiveness of a combination of vitamin A and vitamin E in treating flu cases rather than using vitamin C alone. Group A is the only group that only the old treatment alone is applied to; group 1 participants received no dosage of the new combination of treatments to be tested involving vitamins A and E, unlike the two other groups.
It is obvious now why the experimental participants of group 1 are the control group.
2) A blind experiment/study is one in which the participants don't know which group they belong to, whether they are in the control group or the other experimental group. Like in this case, if this was a blind study, the participants wouldn't know which group they belonged to or which treatment is administered to them.
A double-blind experiment/study is one in which both the conductors of the experiment and the participants in the experiment wouldn't know which group any participant is in. The conductors wouldn't know which participants were in the control or treatment group and the participants too wouldn't have an idea whether they are in the control or treatment group.
