Answer:
Step-by-step explanation:
if you were to be solving for be you it will need to be an equation in order to be able to be solved but in this format it is nearly impossible to obtain an answer.
Answer:
189 components must be sampled.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
That is z with a pvalue of
, so Z = 2.575.
Now, find the margin of error M as such

Assume that component lifetimes are normally distributed with population standard deviation of 16 hours.
This means that 
How many components must be sampled so that a 99% confidence interval will have margin of error of 3 hours?
n components must be sampled.
n is found when M = 3. So






Rounding up:
189 components must be sampled.
∠BCD = 57°
∴ ∠BDR = ∠BCD = 57° (angle that meets the chord and the tangent is equi-angular to the angle at the alternate segment)
Answer:
b
Step-by-step explanation:
there you go dude i did the math for you :)
Hey there!
3 + 67 = 70,
so your answer will be:
x = 3
Hope this helps!
Have a great day (:
