First, you would start with finding the center of the trapezoid. You would multiply 1.6 by 2.4, leaving you with 3.84 sq ft for the center. Then, you subtract 1.6 from 3.2 because you want to find the area of the triangles. You would get 1.6. That means there is a triangle with a base of 1.6 feet and a height of 2.4 feet. The formula for calculating the area of a triangle is base times height divided by 2, and in this case it is 1.6 times 2.4 divided by 2. You would get 1.92, and to find the total amount of ft sq, you would add 1.92 and 3.84 to get 5.76 feet squared(don't forget to label!).
The answer is 7 1/2 becasue if you add the whole #s then the fractions you get the answer
Answer:
0.3
Step-by-step explanation:
First, we get the standard error of the mean using
σm = σ / √N
= 5 / √100
= 0.5
Next, we subtract and add 1.96 standard deviations from the mean (since the confidence interval is 95%). So,
8 ±1.96 (0.5)
= 8 <span>± 0.98
The answer is
</span>E) 8±0.98
D = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
d = sqrt( (5 - 2)^2 + (7 - 3)^2 )
d = sqrt( 3^2 + 4^2 )
d = sqrt(9 + 16)
d = sqrt(25)
d = 5
