The picture in the attached figure
we know that
area of the <span>the shaded region=area of rectangle -area of a kite
area of rectangle=(3x+x)*(x+x)----> 4x*2x---> 8x</span>²
area of a kite=(1/2)*[d1*d2]
where d1 and d2 are the diagonals
d1=4x
d2=2x
so
area of a kite=(1/2)*[4x*2x]----> 4x²
area of the the shaded region=8x²-4x²-----> 4x²
the answer is 4x²
Answer:
7.4 feets
Step-by-step explanation:
Distance from bottom of ladder to side of the house = d
θ = 62 ; height, h = 14
Using trigonometry :
Tan θ = opposite / Adjacent
Opposite = height ; adjacent = d
Tan 62° = 14 / d
1.8807264 * h = 14
d = 14 / 1.8807264
d = 7.44
area of the ceiling = 55 x 55 = 3025 square feet
3025/275 = 11 cans
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The sample mean is 
The sample size is n = 25
The standard deviation is 
Given that the sample size is not large enough i.e n< 30 we will make use of the student t distribution table
From the question we are told the confidence level is 99.7% , hence the level of significance is
=> 
Generally the degree of freedom is 
=> 
=> 
Generally from the student t distribution table the critical value of 
at a degree of freedom of is
Generally the margin of error is mathematically represented as
=> 
=> 
Gnerally the upper control chart limit for 99.7% confidence is mathematically represented as
=> 
=>
Answer:
The answer is 24.4
Step-by-step explanation:
If you add 15.45, 5.00 and 3.95 you get 24.4
