Answer:
height is 4 in
Step-by-step explanation:
total area 72
divide area by base length
72/18= 4
72 total area
18 base length
4 height
Answer:
B
Step-by-step explanation:
each side is corresponded to the other so Q=U and P=S
Answer:
581 m²
Step-by-step explanation:
The area of a trapezoid is determine as the average between the length of both bases T and B (46 and 37 m) multiplied by the height H. The area is:
Assuming that enough turf must be bought to cover the whole extension of the field, the amount of turf that should be purchased is 581 m².
Answer:
The correct answer is option (C)-0.245 = 2.160(0.205)
Step-by-step explanation:
Solution
Given that:
The slope = - 0.245
The size sample = n = 15
The standard error = 0.205
The confidence level = 95
The Significance level= α = (100- 95)% = 0.05
Now,
The freedom of degree = n-2 = 15 -2= 13
Thus,
the critical value = t* = 2.16
By applying Excel = [TINV (0.05, 13)]
The Margin of error is = t* (standard error)
=2.16 *0.205
= 0.4428
