Oliga [24]

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)

A rectangle has a height of 4 and a width of x2 + 3x + 2.
otez555 [7]
<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,

= 4 \times( {x}^{2}  +3x + 2 ) \\   = 4({x}^{2}  + 3x + 2) \\  =   \green{ \boxed{4 {x}^{2}  + 12x + 8}}

Therefore, the answer is 4x² + 12x + 8.
