Step-by-step explanation:
Answer:
about 0.20
Step-by-step explanation:
The speed, acceleration, and distance satisfy the equation ...
v² = 2ad
So the acceleration is ...
a = v²/(2d) = (6 m/s)²/(2×9 m) = 2 m/s²
If we take the acceleration due to gravity to be 9.8 m/s², the coefficient of kinetic friction is the ratio of these:
k = (2 m/s²)/(9.8 m/s²) ≈ 0.20
Hi. The slope of the line is undefined, because it's vertical.
(b) △ABC is similar to △DEF
In △ABC the only angle missing is 30 due to the fact all angles in a triangle add up to 180. So 140+10+(30)=180 and (30)+(10)+140=180
Answer:
(a) The confidence interval is 0.5321<π<0.6679
(b) It can be said, with more than 95% certainty, that the majority of the taxpayers feel that the taxes are too high.
Step-by-step explanation:
First, we calculate the proportion p
For a 95% confidence interval, z-score is 1.96.
The lower and upper limit of the confidence interval can be calculated as
The confidence interval is 0.5321<π<0.6679
(b) The lower limit is above 53%, so it can be concluded that the majority of the taxpayers feel that the taxes are too high.
