Answer:
219.50
Step-by-step explanation
9.75% can be converted into 0.0975 so multiply 0.0975 by 200 you get 19.5. add 19.5 to 200 and you get 219.50
Answer:

And for this case the margin of error would be:

If the level of confidence increase we can conclude that the value of
would increase and the the confidence interval would be wider, since the margin of error increase.
c. Increase; wider
Step-by-step explanation:
Previous concepts
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Solution to the problem
Let's assume that we have a parameter of interest
and we want to estimate the value of p with
and in general the confidence interval if the distribution of p is normal is given by:

And for this case the margin of error would be:

If the level of confidence increase we can conclude that the value of
would increase and the the confidence interval would be wider, since the margin of error increase.
c. Increase; wider
The correct answer would be "C".
The sides and angles are congruent, because:
The sides are proportionate.
7*7=49
11*7= 77
The angles are proportionate because they are touching each other.
The Side- Angle- Side Postulate would be correct when the triangle is equal to TRU.
I hope this helped!
Brainliest answer is always appreciated!
You should move the variable to the same side!
best by addition/substraction:
for example:
2x+5=3x
I will "move" the 3x:
2x+5-3x=0
now you can add up the variables: -x+5=0 (x=5)
essentially you can move it to the other side, changing the sign: + to -, - to +
