Step-by-step explanation:
Total perimeter of garden = 2(8.5+6.33) = 29.66 Sq. ft.
No. of panels required = (29.66)/(2/3) = 45 panels approximately
Step-by-step explanation:
the area of a triangle is
baseline × height / 2
in our case
baseline × 5 / 2 = 20 in²
baseline × 5 = 40
baseline = 8 in
Answer and explanation:
Null hypothesis: p is not 54%
Alternative hypothesis : p is equal 54%
First find standard deviation
Standard deviation is:
σ = √[ P ( 1 - P ) / n ] = √[ 0.54×0.46/220 ] =0.033
The z score is calculated p-P/σ = (0.54-0.50)/0.033 = 1.2121
Therefore we can conclude that proportions are not same and fail to reject the null hypothesis
