Answer:
Neal's decision is to <u>fail to reject </u> the <u>null hypothesis</u> (p 0.066). There is <u>no sufficient </u> evidence to <u>prove</u> the claim that the average electricity consumption of <u>all Ledee household </u>is <u>greater than</u> , <u>854.28 kWh</u>
Step-by-step explanation:
From the question we are told that
The population mean is
The sample size is
The sample mean is
The standard deviation is
The level of significance is
The null hypothesis is
The alternative hypothesis is
The t-statistics is
The p-value is
Now from the given data we can see that
Generally when this is the case , we fail to reject the null hypothesis
So
Neal's decision is to <u>fail to reject </u> the <u>null hypothesis</u> (p 0.066). There is <u>no sufficient </u> evidence to <u>prove</u> the claim that the average electricity consumption of <u>all Ledee household </u>is <u>greater than</u> , <u>854.28 kWh</u>
The area of the hexagon and pentagon area 779.4cm^2 and 84.303cm^2 respectively.
Data;
- apothem = 15
The area of a hexagon with apothem 15 can be calculated by first finding the length of the side of the hexagon.
Length of hexagon can be found using trigonometric ratio;
Making x the subject of formula
And then the length of the side is 2x
The perimeter of the hexagon is;
And the area is given as
The area of the hexagon is 779.4 squared unit.
<h3>Area of the pentagon</h3>The area of the pentagon can be found using several methods, but we can simply find the angle between the sides if we divide the pentagon into 10 pieces and then substitute the formula.
Total area of a pentagon is 360 degree.
The area of a pentagon is given as
The area of the pentagon is 84.303cm^2
From the calculations above, the area of the hexagon and pentagon area 779.4cm^2 and 84.303cm^2 respectively
