Answer:
x=2
Step-by-step explanation:
In the table the ratio of x to y in the first one is 0:2 and ongoing.
Answer:
Step-by-step explanation:
a)
zo=(89.0-92.2)/sqrt((1.5/15)+(1.2/20))
zo=-8.00
p-value=0.0000
Reject the null hypothesis.
b)
95% confidence interval for difference
=(89-92.2)+/-1.96*sqrt((1.5/15)+(1.2/20))
=-3.2+/-0.78
=(-3.98, -2.42)
By law of the sine we have:
sine (y) /35.2=sine (95) / 86
Clearing we have:
sine (y) = (sine (95) / 86) * (35.2)
y = asine ((sine (95) / 86) * (35.2))
y = 24.0632456
Rounding:
y = 24 degrees
Answer:
The answer for this case is given by:
y = 24 degrees
