Answer:
13.9 inches, 14.1 inches
Step-by-step explanation:
The empirical rule tells you 68% of the distribution lies within 1 standard deviation of the mean:
14.0 ± 0.1 = [13.9, 14.1]
About 68% of outside diameters lie between 13.9 inches and 14.1 inches.
Answer:
(2,-3)
Step-by-step explanation:
First, you have to make a Y axis and an X axis. Classes go on the Y axis ( going up and down) and frequency goes on the x axis ( going across) then you graph (in bars) the amount of tallys that match to the amount of frequency. Do u get it? comment if u need more detail:)
Answer: y=28 degrees
Step-by-step explanation:
- To find angle B, all we have to do is subtract 145 from 180 since they're supplementary angles- so angle B is 35 degrees
- Now we can find x, by subtracting 14 from 35-> x=21
- We can create an equation using what we know about B to find y: 35= 63-y
- Solve the equation to get y=28 degrees
In this problem we used supplementary angles and algebra. We also used congruency.
