Answer: 1.2703
Step-by-step explanation:
Given : Sample size : n= 17, which is a small sample (n<30), so we use t-test.
Significance level : 
Then , Critical value : 
Standard deviation: 
The formula to find the margin of error : -
Hence, the error bound (EBM) of the confidence interval with a 90% confidence level.=1.2703
V 23 is the correct answer
The first should be 80 the second part of it should be 210 idk if thats completely right sorry if I'm wrong i hope i helped a little
X- (1/6)= (1/12)
Add (1/6) to each side
x = (1/12)+(1/6)
x=(1/12)+(2/12)
x=(3/12)
x=(1/4) or .25
Answer:
the area is 5.25 and the perimeter is 14
Step-by-step explanation:
first multiply 6cm and 1 3/4 which converts to 1.75, so 6x1.75+10.5 and to find the area of a triangle you multiply the base by the height and divide by 2 so 10.5 divided by 2 is 5.25 for the area, the perimeter is 14 because you're supposed to add all the sides and the sum is the perimeter 20 6 and 1/4 is converted to 6.25 therefore you add 6.25,6, 1.75 together to get 14
