Answer:
16.9°
Step-by-step explanation:
tan x = 1.7/5.6
tan^-1 x = 16.9°
<span>5x-102=13
Add 102 to both sides
5x=115
Divide 5 on both sides
Final Answer: x=23</span>
Answer: 6/121
Step-by-step explanation:
P(not blue)= P(red) × P(green)
=6/11 × 1/11
6/121
Answer:
Now we can find the p value based in the alternative hypothesis and we got:
Step-by-step explanation:
Information given
represent the sample mean
represent the population standard deviation
sample size
represent the value to verify
z would represent the statistic
represent the p value
System of hypothesis
We want to verify if the true mean for this case is 64 or no, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
The statistic for this case is given by:
Now we can find the p value based in the alternative hypothesis and we got:
5 is correct! the real answer is 4.80
