Answer:
0.98 also 98%
Step-by-step explanation:
In this question we have the Lower limit to be 0.16
We have the Upper limit to be 0.24
Such that (0.16+0.24)/2 = 0.40/2 = 0.20
Standard deviation= √(0.2x0.8/545) this gives 0.017134
Next we get margin of error
Margin of error = 0.24-0.20 = 0.04
Z multiplied by sd =0.04
Such that
Z = 0.04/0.017134 =2.33
On this z score, the Corresponding level of confidence is 0.98
Which is 98%
The decomposition of the parallelogram into triangle then into a rectangle is shown below
The measurement we need to calculate the area is the length and the width of the rectangle; 15 feet and 10 feet
Area = 15 × 10 = 150 feet²
Anytime you have text problem you need to write equation just read text bit by bit and write equation as you are reading text!
It starts with "the sum" which means we are using + to sum some numbers.
Next is "three". which means we are summing some 3 numbers.
Next is" consecutive even integers" for that you need to know if 4 is one number than next consecutive even number is 6 or 4+2.
And all is equal to 36.
which means we write:
x + (x+2) + (x+4) = 36 where x is least of those numbers.
3x + 6 = 36
3x = 30
x = 10.
Least consecutive even integer in this task is 10.
