Answer:
(121.576 ; 273.424)
Step-by-step explanation:
Given the data:
175, 125, 180, 220, 240, 245
We can calculate the mean and standard deviation
Mean = Σx/ n = 1185 / 6 = 197.5
Standard deviation = 46.125 (calculator)
The confidence interval :
Mean ± margin of error
Margin of Error = Tcritical * s/sqrt(n)
Tcritical at 99%, df = n - 1 ; 6 - 1 = 5
Tcritical = 4.032
Margin of Error = 4.032 * 46.125/√6
Margin of error = 75.924
Confidence interval :
197.5 ± 75.924
Lower boundary = 197.5 - 75.924 = 121.576
Upper boundary = 197.5 + 75.924 = 273.424
(121.576 ; 273.424)
<h3><u>Given</u>:</h3>
- A rectangle has a height of 4 and a width of x² + 3x + 2.
<h3><u>To find</u>:</h3>
- The area of the entire rectangle.
<h3><u>Solution</u>:</h3>
Hence, we know that area of rectangle is equals to the product of length and breadth.
Therefore, the area of rectangle is,
Therefore, the answer is 4x² + 12x + 8.
