Answer:
The margin of error for the confidence interval is of 0.08 = 8%.
Step-by-step explanation:
A confidence interval has two bounds, an upper bound and a lower bound. The margin of error is half the subtraction between these two bounds.
In this question:
Lower bound: 0.5
Upper bound: 0.66
Margin of error: (0.66 - 0.5)/2 = 0.16/2 = 0.08
The margin of error for the confidence interval is of 0.08 = 8%.
I think it’s D I don’t know
Answer:
15:6:14
Step-by-step explanation:
AB:BD is split into a total of 3+4=7 parts.
AC:CD is split into a total of 3+2=5 parts.
So, if the two ratios are put on a number line together with the points A, B, C, and D, the number line would be split into a total of 35 parts (the LCM of 7 and 5).
AB would be (3/7)*35=15.
CD would be (2/5)*35=14
BC would be 35-(15+14)=6
So, the ratio is 15:6:14.
I kinda need help with this one
