The answers are 'Mike threw more touchdowns in one season.' and 'The differences in the medians and positions of the boxes show that Jeff generally threw more touchdowns than Mike.' I did the assignment myself. I hope this helps everyone!
Answer:
0.40 foot
Step-by-step explanation:
In the first case, a 50 - foot building casts a- foot shadow (1-foot). Let the angle of elevation of the sun from the shadow be represented by θ.
Then:
Tan θ =
Tan θ =
Tan θ = 50
⇒ θ = 50
= 88.8542
=
The angle of elevation is approximately .
For a 20-foot pole,
Tan θ =
Tan =
x =
= 0.4015
= 0.40 foot
The length of the shadow of the pole is 0.40 foot.
Answer:
Step-by-step explanation:
Given is the results of a hypothesis testing for sample mean with population mean.
(Two tailed test at 1% significance level)
Reason:Two tailed because confidence interval is (100,136) with mean =118
Significance level = 100-confidence level
Given that confidence interval is (100,136)
i.e. we can be 99% confident that if samples for large sizes are drawn from this population will have mean within this interval
In this case sample mean 88 does not fall within this interval
Hence our null hypothesis has to be rejected
#13 would be 100%.
#15 would be $9.90.
#17 would be 408.
#19 would be 27840.
#21 would be 26.
Sorry for the late reply.
