What is the area of a regular pentagon with an apothem of 25.1 and a perimeter of 182mm

timurjin [86]

Area = # of sides * side length * apothem / 2
perimeter = 182
one side = 182/5 = 36.4
area = (5 * 36.4 * 25.1) / 2
area = 2,284.1

An advertisement for a popular weight-loss clinic suggests that participants in its new diet program lose, on average, more than

Sauron [17]

The test statistic for the hypothesis would be 1.413.

Given that the participants in its new diet program lose, on average, more than 13 pounds and the mean weight loss of these participants as 13.8 pounds with a standard deviation of 3.1 pounds.

The objective is to text the advertisement's claim that participants in new diet program lose weight, on average, more than 13 pounds.

Hypothesis:

Null hypothesis:H₀:μ=13

Alternative hypothesis:Hₐ:μ>13

Here, μ be the mean weight loss of all participants.

n=30,

Degree of freedom n-1=30-1=29

$\bar{x}$ =13.8 and s=3.1

To test the null hypothesis H₀, the value of test static would be calculated as follows:

$\begin{aligned}t&=\frac{\bar{x}-\mu}{\frac{s}{\sqrt{n}}}\\ t_{29}&=\frac{13.8- 13}{\frac{3.1}{\sqrt{30}}}\\ &=\frac{0.8}{0.566}\\ &=1.413\end$

Hence, the value of the test static for the hypothesis with the mean weight loss of these participants as 13.8 pounds with a standard deviation of 3.1 pounds is 1.413.

Ganezh [65]

Answer:

1. isosceles trapezoid- a trapezoid that has two congruent sides (other than the bases)

2. triangle- a polygon with three sides

3. line symmetry- property where a figure can be folded along a line to create two congruent mirror images

4. line of symmetry- the line which divides a figure into two congruent mirror images

5. rotational symmetry- property where a figure can be rotated less than 360° and still look the same

6. trapezoid- a quadrilateral with one pair of parallel sides
