Answer:
Step-by-step explanation:
The far right side of the triangle is 17 cm, which is the height.
The base would be 34 minus 17 because whole length of the rectangle is 34 and the triangle covers all but 17 of it.
So then you would take 1/2 of 17.
Then multiply it by 17 to get 160.5
Answer:
The margin of error is 3.465
Step-by-step explanation:
Margin of error = t × sd/√n
n = 92, degree of freedom = n - 1 = 92 - 1 = 91, t-value corresponding to 91 degrees of freedom and 90% confidence level is 1.6618, sd = 20
Margin of error = 1.6618×20/√92 = 33.236/9.592 = 3.465
The correct answer would be 6
