Answer:
The standard error increases and the width of the interval increases
Step-by-step explanation:
The variance is equal to the square of the standard deviation. An increase in variance will increase the standard deviation.
The width of the confidence interval can be defined as:

The width is proportional to the standard deviation, so when the variance increases, the standard deviation and also the width of the interval increases.
X+6=2x
As, sides of the rhombus are equal
Therefore,
2x-x= 6
x=6 unit
The amount of money Camden would have in his account after 12 years is equal to $2,374.3.
<h3>How to calculate compound interest.</h3>
To calculate how much money Camden would have in his account after 12 years, we would use the formula for compound interest.
Mathematically, compound interest is given by this formula:

<u>Where:</u>
- P is the principal or starting amount.
- T is the time measured in years.
<u>Given the following data:</u>
Principal = $1400.
Interest rate = 4.5% = 0.045.
Time = 12 year.
Substituting the given parameters into the formula, we have;

A = $2,374.3.

Answer:
≈107
Step-by-step explanation:
58.311 will round <em>down </em>since 0.311 is less than half or 0.5. It will become 58. 49.35 will also round <em>down </em>since 0.35 is less than 0.5. This will be 49. 58+49=107. Since 107 is not the exact answer, you will use the approximately sign, or ≈.
